Biomaterials 24 (2003) 1093–1099. Investigators concluded that zirconia could be considered a superior ceramic coating to alumina. In a study conducted by Deprich et al,34 24 screw-type zirconia implants (Konus Dental, Bingen, Germany) with acid-etched surfaces were compared with 24 implants of commercially pure titanium with acid-etched surfaces. The same researchers28 observed the role of osseointegration around the 1-stage zirconia screw implant (Goei) with various conditions for loading support after 2 years of function in monkeys. To make this possible, Z-Systems has developed the Z-Look3 implant system. Epub 2009 Mar 8. Review. Jank S, Hochgatterer G. Success rate of two-piece zirconia implants: a retrospective statistical analysis. Rough surfaces and in particular zirconia-blasted implants seemed to favor bone deposition on the titanium surface. After thorough cleaning, decontamination and priming of the abutment and abutment space of the implant, both maxillary and mandibular abutments were cemented to the implants with a resin modified glass ionomer cement (Fuji GC cement) (Figure 13). Blaschke et al46 reported that dental implants made from zirconia are a feasible alternative to titanium dental implants. The Italian Journal of Dental Medicine is published quarterly. 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. Alternative treatment options were presented including overdentures on four ceramic implants. 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). Two-piece zirconia implants are indicated in cases where obtaining implant parallelism is a challenge, poor bone quality (bone D3/D4), partial edentulism, restoration of the posterior quadrants, regenerative therapy, complex implant placement and in full-arch and full mouth oral rehabilitation. Given the sinus elevation requirement, future investigators may exclude patients with less than 5 mm residual bone. Sennerby et al39 observed bone tissue responses to machined and surface-modified zirconia implants. Kwon T, Bain PA, Levin L. Systematic review of short- (5-10 years) and long-term (10 years or more) survival and success of full-arch fixed dental hybrid prostheses and supporting implants. Cranin et al20 investigated the osseointegration of vitallium implants with the addition of ceramic coatings, such as alumina (n  =  9) or zirconia (n  =  9). Ceramic Implants are made from Zirconia—a biocompatible ceramic material that fosters complete assimilation into jaw bone. Today, dental restorations are made out of materials that offer many practical and aesthetic advantages over conventional alternatives. However, even when there is good bone support, the monolithic structure of these implants can lead to difficulties in  terms of surgical insertion in patients with limited opening, short clinical crowns and limited interocclusal space. The patient has been followed up periodically for the last eighteen months and there have been no complications to date (Figure 21 and Figure 22). Fracture values for metal-ceramic and Procera crowns after artificial loading were significantly higher than for the loaded Empress I crowns. The interface reaction of bone toward coated implants was faster than toward uncoated ones. Case report 1 had a three-year follow-up, while the second case was evaluated up until 18 months. The implant-abutment connection not only ensures high stability of the abutment, preventing potential rotational movements of the prosthesis with the hexagonal connection, but also a greater protection of the hexagonal seal provided by the conical seal that reduces the gap between implant and abutment thus preventing bacterial infiltration (13). Dental implants are the single most effective way to preserve foundational bone in the jaw and restore the function and beauty of your smile. This is brought about by inserting the cement of the fixed prosthesis, which combines with the cement of the abutment and creates a seal that according to the manufacturer is supposed to limit bacterial infiltration (Z3c Z-SystemS AG, Oensingen, Switzerland). Prettau ® Zirconia is stronger and much more durable than acrylic. The aim of this study is to review clinical and research articles conducted on zirconia dental implants, compare them with titanium dental implants, and provide information on zirconia dental implant osseointegration and mechanical strength. Impiego di impianti in zirconia per le riabilitazioni delle edentulie singole e multiple: protocollo chirurgico-protesico. The following paper focuses on conventional titanium implants and more recently introduced and increasingly popular zirconia implants. There are no reports available in the literature on the loss of retention of the abutment for two-piece implants with cemented abutments using self-curing resin cements (16,17). The machined zirconia implants showed statistically significant lower RTQ values than the other 2 implant types after 8 and 12 weeks, and the SLA titanium implant showed significantly higher RTQ values than the sandblasted zirconia surface at 8 weeks. The average surface roughness of zirconia with 3% Y2O3 and of zirconia with 4% CeO2 was correlated with the starting powder size and substrates. In fact, it is necessary to ensure prosthetic designs that redirect occlusal forces in a vertical/axial direction. No significant differences in strength and stiffness of attachment between the 2 implant designs were detected at this time point. a solution for replacing missing teeth or broken down teeth with a fixed 41. Sugiura T, Yamamoto K, Horita S, Murakami K, Tsutsumi S, Kirita T. Effects of implant tilting and the loading direction on the displacement and micromotion of immediately loaded implants: an in vitro experiment and finite element analysis. Zirconia implants can also be useful for people with thinner gum tissue and where a metal implant could potentially show through the gum. 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. Mechanical modifications include machining processes and sandblasting processes, while chemical ones include etching processes. All implants showed new bone trabeculae, vascularized medullary spaces, and close contact with preexisting bone at 2 weeks. Borgonovo AE, Censi R, Ghirlanda G et al. In the last study conducted by Stübinger et al,38 the influence of erbium-doped yttrium aluminium garnet (Er∶YAG), carbon dioxide (CO2), and diode laser irradiation on surface properties of polished zirconia implants was evaluated. Langhoff et al18 compared the BIC of chemically modified (plasma-anodized or coated with calcium phosphate) titanium implants, pharmacologically coated (bisphosphonate or collagen type I with chondroitin sulphate) titanium implants, SLA titanium implants, and SLA zirconia implants. 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. Int J Oral Maxillofac Implants. Surface analyses revealed that the highest surface roughness was measured for the SLA titanium implant, followed by the sandblasted zirconia implant and the machined zirconia implant. 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. Wennerberg A, Albrektsson T. Effects of titanium surface topography on bone integration: a systematic review. Clin Oral Implants Res 2015;26(4):413–8. Only three mandibular teeth were present (Figure 17) with no teeth remaining in the left quadrant and moderate to advanced vertical bone loss. Franchi et al23 also evaluated in an animal study peri-implanted tissues for titanium implants with different surfaces—smooth, titanium plasma sprayed, and zirconia blasted. Clinically, all implants were immobile for 24-month loading, and healthy peri-implant mucosa was achieved in the single freestanding, connected freestanding, and implant-tooth support groups, with favorable values for clinical parameters. Int J Dent. Association of masticatory performance with age, posterior occlusal contacts, occlusal force, and salivary flow in older adults. The zirconia implants demonstrated a slightly higher degree of bone apposition (54%–55%) compared with the titanium implants (42%–52%) at the 2-week time point, but bone apposition was higher in titanium (68%–91%) than in zirconia (62%–80%) at 4 weeks. 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.

It was found that zirconia coating would enhance implant osseointegration. A two-phased treatment plan consisting initially of full arch extractions, immediate implant placement in both arches and soft reline immediate dentures for both arches. Zirconia dental implants are extremely strong and durable, and their long-term success is one of the most attractive features of the system. (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. 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. Implant stability had to be subjectively evaluated since there is no device designed to measure the stability of two-piece ceramic implants with cementable abutments. J Oral Implantol. All implants returned average Implant Stability Quotient Values (ISQ) values above 74. A study conducted by Spies et al. Corrosion of titanium in presence of dental amalgams and fluorides. The Snow ceramic implant system is the only 100% ceramic system available (metal- and plastic-free) – the drills, implants, abutments, and setscrews are all zirconia. Additionally, studies have shown that titanium and zirconia implants have a very similar bone to implant contact or Osseointegration (Manzano et al. The surface roughness of zirconia was found to be comparable with that of titanium implants. These abutments used on two-piece implants with dedicated internal morphology (Zeramex® T Zeralock™, Zeramex®, Dentalpoint AG, Spreitenbach, Switzerland) enable mechanical fixing by a rotational movement of 60°. The patient has been followed up for the last three years and there have been no complications to date. 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. Cionca N, Müller N, Mombelli A. Two-piece zirconia implants supporting all-ceramic crowns: A prospective clinical study. Furthermore, Oliva et al50 reported the first clinical case of an ovoid zirconia dental implant. Dentists often recommend crowns as a way to support broken, weak, or misshapen teeth. On the basis of available peer-reviewed data, osseointegration of zirconia dental implants may be comparable with that of titanium implants. The PubMed search resulted in 108 articles. The patient elected not to have it replaced with another implant. The carbon-PEEK screws (Figure 7) are made of carbon fibre reinforced PEEK (Vicarbo®, Dentalpoint AG, Spreitenbach, Switzerland). 2011;37:367–376. The zirconia frameworks and permanent prosthetics were designed and milled based on the wax teeth set up. Lopes A, Maló P, de Araújo Nobre M, Sánchez-Fernández E, Gravito I. Titanium and titanium alloys are widely used for fabrication of dental implants. Insertion torque value for all implants was 25 Ncm and all implants showed good initial clinical primary stability. In the other study,37 machined zirconia, sandblasted zirconia, and SLA zirconia surfaces were evaluated. Criteria for success of osseointegrated endosseous implants. These patterns could be characterized as favorable or nondestructive. & Pozhitkov, Alexander & McLean, Jeffrey & Kotsakis, Georgios. A longitudinal study of the survival of All-on-4 implants in the mandible with up to 10 years of follow-up. Nonetheless, it should be noted that zirconia has intrinsic characteristics and surface properties that allow limited plaque organisation and limited bacteria adherence and microbiota compared to titanium(12). The short-term cumulative survival rates and the MBL of zirconia implants in the presented systematic review are promising. The tightening for the titanium and gold micro-screws must not exceed 15 Ncm, while for the PEEK micro-screws it must not exceed 5 Ncm.
