Ceramic implantology, Two-piece implants, Zirconia implants. Epub 2014 Jun 26. Review. 2005;7(suppl 1):S13–S20. Nordlund et al 21 studied the tissue integration of 3 types of implant materials in monkeys: (1) alumina with 4% zirconia and 25% magnesia, (2) alumina with 25% silicon carbide, and (3) unalloyed titanium implants. Malo P, Rangert B, Nobre M. “All-on-Four” immediate- function concept with Branemark System implants for completely edentulous mandibles: a retrospective clinical study. Another common problem of all the systems that involve a connection screw is the possibility that it can become unscrewed. Full-arch implant rehabilitation techniques use a minimum of four implants per arch to treat complete edentulism. Malo P, de Araujo Nobre M, Lopes A, Francischone C, Rigolizzo M. “All-on-4” immediate-function concept: a clinical report on the medium (3 years) and long-term (5 years) outcomes. Every effort is made to avoid a micro-gap during cementation of the abutment, but it is not always achieved. All on 4 teeth can fracture and break This rarely happens if the all on 4 teeth are made of an up to date material like zirconia. SEM analyses demonstrated that diode and Er∶YAG lasers did not cause any visible surface alterations. Additionally, studies have shown that titanium and zirconia implants have a very similar bone to implant contact or Osseointegration (Manzano et al. Histologically, the direct bone-implant interface was generally attained in all observed zirconia implants. (16), the success rate and survival rate were 93.3% for zirconia implants and 100% for titanium implants at a 24-month follow-up. The zirconia implants presented 20% more bone contact than the titanium implants at 2 weeks, improved toward 4 weeks, then were reduced at 8 weeks. 2014). The same protocol was followed for the mandibular implants and four implants were placed with similar insertion torques and primary stability observations. It has been established that and according to the Gell and Coombs classification, type IV immunological reactions can occur following placement and/or restoration when using titanium and titanium alloys. In another study,1 Gahlert et al examined zirconia implants with a machined or a sandblasted surface and compared them with SLA titanium implants. Of the various types of laser usable for this treatment, a study conducted by Delgado‐Ruíz et al. The cemented portion of the abutment remains cemented within the implant and removal often leads to destruction of the internal connection portion of the implant. Zirconia seems to be a suitable implant material because of its toothlike color, mechanical properties, biocompatibility, and low plaque affinity. One-piece implants are particularly suitable for the anterior quadrants especially in the case of thin biotypes, in the restoration of single-tooth edentulism, and in patients who have optimum bone support that is able to withstand mastication or other forces during the osseointegration phase. 2017 Aug;47(4):251-262. doi:10.5051/jpis.2017.47.4.251. Insertion torque value for all implants was in the range of 20 to 25 Ncm and all implants showed good clinical primary stability. Kohal et al32 evaluated the soft and hard tissue conditions of sandblasted zirconia implants (ReImplant, Hagen, Germany) and compared them with sandblasted and acid-etched (SLA) titanium implants. This implant type allows the two-piece to be treated in a similar way to the one-piece type. The BIC percentage was 31.8 ± 3.05% for uncoated titanium implants and 43.8 ± 2.05% for titanium implants coated with zirconia at 4 weeks. The success and survival rate of implants in zirconia are comparable to that of titanium implants, and several authors have compared the two implants (Zr-Ti) in order to evaluate their clinical reliability (14). The operative phases concerning the cementation are very simple, which means it can be used even by less experienced operators. Zirconia implants, used initially in their one-piece variant, have been further developed and we now have available two-piece versions of ceramic implants. In addition to the survival rate, the review also examined average marginal bone loss values after 1 year and at the end of the follow-up period. This paper is to show two case reports that demonstrates the possibility and feasibility of full-arch implant restorations with two-piece zirconia implants. Of particular interest are the systems that involve a combination of the two connection techniques, as they require both a micro clamping screw and cementation (SDS2.0, SDS Swiss Dental Solutions AG, Kreuzlingen, Switzerland). In addition, titanium implants were used. Clin Oral Implants Res 2013 May;24(5):569-75. The same researchers compared osteoblast behavior on structured zirconia (Konus) and titanium surfaces in another study.35 Attachment kinetics, proliferation rate, and synthesis of bone-associated proteins on both surfaces were examined and compared. Most of the time, I recommend Titanium dental implants to my patients and I would opt for Titanium in my own mouth. 2014 Oct;42(10):1228-41. doi: 10.1016/j. Zirconia implant blanks (ceramic.implant, VITA) were sandblasted (105‐μm alumina, 6 bar), subsequently HF‐etched, and finally heat‐treated at 1250°C. Additionally, the use of one-piece implants necessarily involves the use of a temporary tooth that must be free of occlusion and lateral contact or a protective appliance. Besides the detachment of the abutment, the greater problem lies in the fact that, in the initial phases of decementation, there are micro-movements of the structure. Using implants with these screws means that the restoration cannot be defined as completely metal-free, although it should be specified that the metal connection screw is not in direct contact with the patient's tissues. In January 2020, Straumann, a leading dental implant company, received FDA approval for release of the Snow ceramic implants. Implant bulk material and design, restoration type, and the application of minor augmentation procedures during surgery, as well as the modes of temporization and loading, had no statistically significant influence on MBL. The most frequently used zirconia surface treatments involve mechanical and chemical subtractive processes. Impiego di impianti in zirconia per le riabilitazioni delle edentulie singole e multiple: protocollo chirurgico-protesico. Once the permanent prosthetics phase started, the removable dentures were either duplicated or new teeth set ups and wax try-ins were done in order to improve aesthetics, occlusion and fit. The full-arch restoration treatment concept was pioneered by Malo and colleagues. They are considered to be inert in the body and exhibit minimal ion release compared with metallic implants. Clin Oral Implants Res 2012:23:281-286. The periodontally involved teeth had mobility type II with moderate to advanced bone loss and gingival recession (Figure 16). As a result ceramic implants lost their appeal and eventually manufacturers withdrew them from the market. Dentists often recommend crowns as a way to support broken, weak, or misshapen teeth. Several two-piece systems involve the use of carbon-PEEK connection screws (Zeramex® P6 and XT, Zeramex®, Dentalpoint AG, Spreitenbach, Switzerland; NobelPearl, Nobel®, Nobel Biocare Italiana srl, Vimercate, Italy). Dubruille et al29 compared the BIC on 3 types of dental implants: titanium, alumina, and zirconia (Sigma, Lausanne, Switzerland); these were placed into the dog mandible. Other Full Mouth Implant Cases Exist. At 2-year follow-up, a stable implant and an unchanged peri-implant marginal bone level were observed. Buczynski BW, Kory MM, Steiner R, Kittinger TA, Ramsier RD. Wang JL, Liu RL, Majumdar T et al.A closer look at the in vitro electrochemical characterisation of titanium alloys for biomedical applications using in-situ methods. At 1, 4, or 12 weeks, BIC was slightly better on titanium than on zirconia surfaces. Ayub KV, Ayub EA, Lins do Valle A, Bonfante G, Pegoraro T, Fernando L. Seven-Year Follow-up of Full-Arch Prostheses Supported by Four Implants: A Prospective Study. In addition to excellent cosmetic results, zirconia implants allow a degree of osseointegration and soft tissue response that is superior to that of titanium dental implants. At day 3, cell growth was significantly higher on the zirconia surfaces than on the titanium surfaces. 3.1. Clinical Implant Dentistry and Related Research. Overall, the marginal bone loss was respectively 0.89 mm (CI 95% 0.60-1.18) and 0.98 mm (CI 95% 0.79-1.18). However, the CO2 laser produced distinct surface alterations to zirconia. Franchi et al22 evaluated peri-implant tissues of zirconia-coated titanium implants and acid-etched titanium implants by light microscopy. In the nonloaded group, fracture strength was 531.4 N for titanium, 512.9 N for zirconia-Empress I, and 575.7 N for zirconia-Procera. After minor occlusal adjustments, the all-ceramic porcelain fused to zirconia cementable hybrid bridges were bonded to the implant-abutment assemblies following the previously described cementation protocol (Figure 15). Conventional Impressions were made using polyvinylsiloxane heavy and light body with the closed tray technique. Scarano et al30 demonstrated the bone response to zirconia implants at 4 weeks. Because of potential immunologic and possible esthetic compromises with titanium implants, novel implant technologies are being developed. The mean RTQ for machined zirconia implants was 25.9 N/cm, the mean RTQ for zirconia rough implants was 40.5 N/cm, and the mean RTQ for SLA titanium implants was 105.2 N/cm. Zirconia implant fracture occurred at 725 to 850 N when the implant heads were not prepared, and at 539 to 607 N when prepared. Is Metal Particle Release Associated with Peri-implant Bone Destruction? Depprich R, Zipprich H, Ommerborn M, Mahn E, Lammers L, Handscel J et al. Cemented two-piece zirconia ceramic implants for full mouth rehabilitation. Although zirconia may be used as an implant material by itself, zirconia particles are also used as a coating material of titanium dental implants. Today, dental restorations are made out of materials that offer many practical and aesthetic advantages over conventional alternatives. Surgical planning was done on a computer using the native software of the Prexion 3D CBCT scanner. Internal square connection with parallel sides (Straumann. 2010 Mar;27(1):3-10. doi: 10.1111/j.1741 2358.2009.00294.x. Coated or surface-modified zirconia implants showed higher removal torque values than machined zirconia implants. The arrival of zirconia a material with good mechanical properties, high biocompatibility and with excellent aesthetic result encouraged researchers to investigate its possible use as a material for endosseous implants. The overall success rate was reported as 98%. A custom-made 2-piece zirconia implant was used to replace a left upper central incisor with zirconia abutment and a zirconia-based single crown. These patterns could be characterized as favorable or nondestructive. They are reliable and well proven. The Osstell device was used to measure the implant stability level for each implant after four months of healing time (Osstell Ô, Integration Diagnostics, Gothenburg, Sweden). These failed implants were placed in situations where sinus elevation was required. The Italian Journal of Dental Medicine is published quarterly. Clin Oral Impl Res 2007;18:662-8. Clin Oral Implants Res 2017; 28(1):29-35. Sennerby L, Dasmah A, Larsson B, Iverhed M.

A short communication, Creative Commons Attribution-NonCommercial 4.0 International License (CC BY-NC 4.0). Borgonovo AE, Censi R, Ghirlanda G et al. Specifically, in a study conducted by Payer et al. Also, zirconia implants are very hard and strong. External connections allow in some cases the simplified engagement of the implant in several possible positions (Zeramex® P6, Zeramex®, Dentalpoint AG, Spreitenbach, Switzerland) and also, for the prosthetic stages, they allow an indirect capture of the impression free of tension. A recent review of the literature conducted by Haro Adánez Mireira et al. The growth of osteoblasts on these implant surfaces treated both chemically and mechanically has been widely documented (18). Some commercially available implants also have cylindrical-conical models (Zeramex® XT, Zeramex®, Dentalpoint AG, Spreitenbach, Switzerland; NobelPearl, Nobel®, Nobel Biocare Italiana, Vimercate; SDS 2.0, SDS Swiss Dental Solutions AG, Kreuzlingen, Switzerland). jdent.2014.05.016. A two-phased treatment plan was put in place with extractions of the remaining maxillary teeth, immediate implant placement in both arches and soft reline both maxillary and mandibular immediate dentures. (6) confirmed that the increase in the rough surface of sandblasted and etched zirconia implants has an important influence on bone integration and bone stability. (2018). Sandblasting with aluminium oxide in Y-TZP implants, performed before the sintering process, this manufacturing sequence protects the zirconia from transforming from the tetragonal phase to the monoclinic phase therefore avoiding to undermine its physical properties. When dentists perform implant therapy for teeth replacement in full-arch indications, not only do they restore form and function, but also improve the quality of life for the patient. Payer M, Heschl A, Koller M, Arnetzl G, Lorenzoni M, Jakse N. All-ceramic restoration of zirconia two-piece implants - a randomized controlled clinical trial. Dent Mater 2018 Sep 1. pii: S0109-5641(18)30475-5. 2017 Jul/Aug;32(4):904-911. doi: 10.11607/jomi.5578. Int J Oral Maxillofac Implants 2013;28(1):103-108. A sandblasting process with round zirconia particles may be an alternative surface treatment to enhance the osseointegration of titanium implants. Int J Oral Maxillofac Implants. The material also provides high strength, fracture toughness, and biocompatibility.14 The inflammatory response and bone resorption induced by ceramic particles are less than those induced by titanium particles, suggesting the biocompatibility of ceramics.15,16. The results of this study reveal that two-piece zirconia implants have competitive success rates. At 12 weeks, ultrastructural evidence of successful osseointegration of both implant systems was found. It was reported by Roehling et al and Koch et al that the general rate of zirconia implants representing cracks of the implant head was nearly twenty two and thirty percent respectively. Screw-retained full mouth rehabilitation with hybrid: two-piece ceramic implants. In fact, it is necessary to ensure prosthetic designs that redirect occlusal forces in a vertical/axial direction. The surfaces of ceramic implants have been constantly evolving over the years, which has been necessary to achieve higher performance characteristics for improved osseointegration. The success rate has progressively increased, with initial levels higher than 96.7% in the first generations, up to levels exceeding 98.5% in the latest generations. Materials and methods. In the other study,37 machined zirconia, sandblasted zirconia, and SLA zirconia surfaces were evaluated. J Periodontal Implant Sci. The mean mineralized BIC achieved after 9 months of healing and 5 months of loading was 72.9% for titanium implants and 67.4% for zirconia implants. Clin Implant Dent Relat Res 2003;5:2-9. Zembic A, Johannesen L, Schou S, Malo P, Reichert T, Farella M, Hammerle C. Immediately restored one-piece single-tooth implants with reduced diameter: one-year results of a multi-center study. The patient has been followed up for the last three years and there have been no complications to date. Its specific feature is in its intrinsic structure as the carbon fibres are continuous and go in a longitudinal direction (60% CF) and are held in a matrix of PEEK (Polyetheretherketone 40%). With the aging population, the reliability of dental implants, the comfort and convenience of oral rehabilitation with fixed prosthetics has led to an increase in requests by patients for full arch and full mouth rehabilitation on dental implants. Gil-Montoya JA, de Mello AL, Barrios R, Gonzalez-Moles MA, Bravo M. Oral health in the elderly patient and its impact on general well-being: a nonsystematic review.

Payer M, Arnetzl V, Kirmeier R, Koller M, Arnetzl G, Jakse N. Immediate provisional restoration of single-piece zirconia implants: a prospective case series - results after 24 months of clinical function. The smartpegs specifically designed for the implants were screwed into the implants and stability measurements were made using resonance frequency analysis technology (Figure 19). The aim of the study was to systematically analyze the effect of these process steps on surface morphology and mechanical strength of the implants. The evolution of ceramic implantology has led to the introduction of two-piece implants, in response to the growing demand for metal-free restorations and to the demand for an alternative that would allow its use in cases where single-piece types in zirconia were not suitable. Subject: Zirconia Dental Implants: A Literature Review, (Optional message may have a maximum of 1000 characters. Pirker et al48 placed a zirconia implant to the maxillary first premolar region immediately and evaluated the clinical outcome of this implant. For example, two-piece implants are indicated in cases where ideal implant parallelism is difficult to achieve, poor bone quality (bone type D3/D4), partial edentulism, restoration of the posterior quadrants, regenerative therapy, operative difficulties in implant insertion and in full-arch restoration of edentulous patients. The surface roughness of zirconia was increased by airborne particle abrasion and additionally by acid-etching. Nordlund et al21 studied the tissue integration of 3 types of implant materials in monkeys: (1) alumina with 4% zirconia and 25% magnesia, (2) alumina with 25% silicon carbide, and (3) unalloyed titanium implants. Titanium is an ideal material for implants because it resists fracture in places with high chewing load. 2017 Apr;19(2):233-244. doi:10.1111/cid.12456. Uni Köln 2014/2015]. Internal cone connection (Z3c Z-Systems AG, Oensingen, Switzerland; SDS® 2.0, SDS Swiss Dental Solutions AG, Kreuzlingen, Switzerland). Thus, the purpose of this review is to summarize research articles conducted on zirconia dental implants, compare them with titanium dental implants, and provide information on zirconia dental implant osseointegration. With regards to abutment-implants connections by means of  luting cements for two-piece zirconia implants, joining the abutment to the implant require the use of a resin modified glass ionomer cement preceded by decontamination and priming of the surfaces.

Once it was determined that the patient had adjusted to and was comfortable with the provisionals, they were scanned and duplicated in a zirconia framework which was manufactured with CAD/CAM milling technology. snap on implant dentures. Investigators concluded that zirconia could be considered a superior ceramic coating to alumina. Gahlert M, Roehling S, Sprecher CM, et al. Three clinical studies investigated zirconia implants. Zirconia bioceramic composites have emerged as reliable and predictable alternative implant materials.

Most of the studies were conducted in vitro.1,2,11,18,20–45 Osseointegration and bone-implant contact (BIC) were investigated in 18 articles,2,18,20–35 surface analyses in 4 articles,1,36–38 removal torque testing (RTQ) in 4 studies,1,39–41 mechanical strength in 4 articles,11,42–44 and stress analyses in 1 article.45 Three clinical studies involved clinical survival rate.46–48 Other published articles were case reports49,50 and reviews.51,52, Eighteen articles discussed osseous healing, histologic analyses, and BIC of zirconia dental implants.2,18,20–35 Seven of these articles evaluated zirconia as a coating material,20–26 and 11 evaluated zirconia dental implants.2,18,27–35. However, one of the mandibular implants failed to osseointegrate and was removed two months after placement. Carbon-PEEK connection screws have proven to be able to better withstand the tension forces thanks to their intrinsic adaptation capacity. Titanium and titanium alloys are widely used for fabrication of dental implants. However, these novel technologies must maintain the characteristics that provide titanium implants with their high success rates. The literature indicates the presence of a demonstrable immunological reactivity in about 5% of patients with titanium implants. Acta Biomater 2017 May;54:469-478. In addition, in order to increase the stability of the connection, abutments have recently been introduced that have a ring in PEEK at the base (Zeralock™ PEEK ring, Zeramex®, Dentalpoint AG, Spreitenbach, Switzerland). Spies BC, Fross A, Adolfsson E, Bagegni A, Doerken S, Kohal RJ. The implant's ability to withstand occlusal load enables its long-term survival without loss of osseointegration. Degidi M, Daprile G, Piattelli A. Int J Oral Maxillofac Implants 2010 May-Jun; 25(3):558-61. This aspect is justified by the fact that using only one parameter fails to guarantee an adequate spatial distribution in the surface topography. doi: https://doi.org/10.1563/AAID-JOI-D-09-00079. Gerodontology. Element release from titanium devices used in oral  and maxillofacial surgery. According to Albrektsson et al, the quality of the implant surface is one major factor that influences wound healing at the implantation site and subsequently affects osseointegration.17 Therefore, various chemical and physical surface modifications have been developed to improve osseous healing.2 To improve surface properties, 2 main approaches may be used, such as optimizing the micro-roughness (sandblasting, acid-etching) or applying bioactive coatings (calcium phosphate, bisphosphonate, collagen).18 The clinical use of zirconia dental implants is limited because fabrication of surface modifications is difficult, and smooth implant surfaces are not beneficial for osseointegration because of poor interaction with tissues.19. Prettau ® Zirconia is stronger and much more durable than acrylic. The carbon-PEEK screws (Figure 7) are made of carbon fibre reinforced PEEK (Vicarbo®, Dentalpoint AG, Spreitenbach, Switzerland). Delgado-Ruíz RA, Calvo-Guirado JL, Moreno P, Guardia J, Gomez-Moreno G, Mate-Sánchez JE, Raminez-Fernández P, Chiva F. Femtosecond laser microstructuring of zirconia dental implants. In fact, a recent study has observed a superior bone bonding around sandblasted and etched implants compared to those that had undergone sandblasting treatment only (25). A study conducted by Spies et al. Sennerby L, Dasmah A, Larsson B, Iverhed M. bone tissue responses to surface-modified zirconia implants:a histomorphometric and removal torque study in the rabbit. (15) on 17 clinical studies observed that, for a total of 1704 zirconia implants (1521 one-piece, 183 two-piece), monitored for a period of between 1 and 7 years, the average survival rates were 95% (95% CI 91-97%). For a rapidly aging and health-conscious population, the need for replacement solutions of missing teeth is growing as well as the request for alternative methods and materials that are more flexible and safer (31,32). The remaining maxillary teeth were non-restorable (Figure 10) and the mandibular ridge presented moderate resorption of bone. They are virtually indistinguishable from natural teeth and gums. A cone beam CT scan was obtained and reviewed to assess bone levels, anatomy as well as critical anatomical structures in the areas of planned implant placement. This is of great concern when the maxillary incisors are involved.5 Furthermore, reports suggest that metals are able to induce a nonspecific immunomodulation and autoimmunity.6 Galvanic side effects after contact with saliva and fluoride are also described.7 Although allergic reactions to titanium are very rare, cellular sensitization has been demonstrated.8,9, Because of these disadvantages, novel implant technologies that produce ceramic implants are being developed.10 However, ceramics are known to be sensitive to shear and tensile loading, and surface flaws may lead to early failure.
