Materials and methods. Although fabrication of surface modifications for zirconia is difficult, CO2 lasers revealed distinct surface alterations to zirconia, and additional studies about this technique may help to improve surface roughness. The surfaces of ceramic implants have been constantly evolving over the years, which has been necessary to achieve higher performance characteristics for improved osseointegration. Our dentist, Dr. Leonard Umanoff, is experienced in planning and placing titanium and zirconia dental implants. The zirconia frameworks and permanent prosthetics were designed and milled based on the wax teeth set up. However, the CO2 laser produced distinct surface alterations to zirconia. Insertion torque value for all implants was 25 Ncm and all implants showed good initial clinical primary stability. Is Metal Particle Release Associated with Peri-implant Bone Destruction? Of these, 30 were laboratory studies, 3 were clinical studies, 2 were case reports, and 2 were review articles. 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. Becker J, John  G, Becket K, Mainusch S, Diedrichs G, Frank S. Clinical performance of two‐piece zirconia implants in the posterior mandible and maxilla: a prospective cohort study over 2 years. (28,29,30). In general, chemical treatments lead to an improvement of the morphological alterations since, in topographic terms, they create a more uniform surface than just sandblasting. Most teeth were periodontally involved or fractured at the gingival level. Ito H, Sasaki H, Saito K et al. An anatomically oriented ovoid zirconia implant (CeraRoot Type 14), which was specially designed to replace a missing premolar, was discussed. This modality has been well proven and documented to assess implant stability and readiness to be restored. ), Department of Prosthodontics, Faculty of Dentistry, Yeditepe University, Goztepe, Istanbul, Turkey. On the basis of available peer-reviewed data, osseointegration of zirconia dental implants may be comparable with that of titanium implants. Prettau zirconia bridge reviews have been very good so far. 10.1111/cid.12676. Once the waxed prototypes were approved, multiple clinical photographs and bite registration records were taken for effective transfer of information with the dental laboratory. Wax rims, wax try-in were done for space analysis, occlusion, speech and aesthetics (Figure 20). Whether they are requesting treatment for ill-fitting, poorly functioning removable prosthetics or a long-term solution for terminal dentition, these patients experience discomfort, diminished chewing capability (34), suffer from digestive problems, malnutrition and low self-esteem as a result of their condition. Unfavorable soft tissue conditions or recision of the gingiva may lead to compromised esthetics. 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. In the other study,37 machined zirconia, sandblasted zirconia, and SLA zirconia surfaces were evaluated. Two-piece implants, on the other hand, are more versatile than one-piece implants in the situations described above, since the dentist can opt for submerged healing of the implant in cases where this situation is indicated and can choose between different types of abutment. Why Prettau ® Zirconia is a better choice for dental bridges than acrylic with denture teeth. Emami E, de Souza RF, Kabawat M, Feine JS. Zirconia implants, which may also be referred to as ceramic implants, seems to be the new implant material. Corrosion of titanium in presence of dental amalgams and fluorides. In clinical implant dentistry, such level of failure is unacceptable [4]. In detail, sandblasting ensures an adequate bone adhesion, while acid etching evens out the topography of the implant, smoothing the peaks. S54630. Blaschke et al46 reported that dental implants made from zirconia are a feasible alternative to titanium dental implants. At 1, 4, or 12 weeks, BIC was slightly better on titanium than on zirconia surfaces. The carbon-PEEK screws (Figure 7) are made of carbon fibre reinforced PEEK (Vicarbo®, Dentalpoint AG, Spreitenbach, Switzerland). Noncoated zirconia implants were used as controls. As already mentioned, in the two-piece system, the implant can be connected to the abutment in two different ways: screwed or cemented. However, these novel technologies must maintain the characteristics that provide titanium implants with their high success rates. Thus, the inclusion criteria for articles were as follows: (1) Articles were related to zirconia dental implants, and (2) abstracts were obtained when the full texts could not be obtained. Given the sinus elevation requirement, future investigators may exclude patients with less than 5 mm residual bone. However, it was quickly abandoned because, although it achieved good osseointegration, in the longer term its mechanical properties proved insufficiently resilient to mastication and function. Criteria for success of osseointegrated endosseous implants. Clinical Implant Dentistry and Related Research. Minamizato et al42 investigated the compressive strength of the blade type of zirconia dental implants with tunnels drilled by laser process, and found that specimens with tunnels showed lower compressive strength (237 kg/mm2) than specimens without tunnels (371.5 kg/mm2). Stress values were found to be similar for both models for all regions. 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. The patient elected not to have it replaced with another implant. They stimulate gum tissue growth to improve healing; They fuse with the jawbone like titanium implants for stability; Hypoallergenic and do not release toxins To achieve a porous surface, the zirconia implants were coated with 2 different slurries containing zirconia powder and a pore-former, which gave different surface structures. Sennerby et al39 observed bone tissue responses to machined and surface-modified zirconia implants. 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. Surgical planning was done on a computer using the native software of the Prexion 3D CBCT scanner. 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. With regard to abutment fractures, the fracturing of the abutment has been recorded in only a few clinical studies (17, 20,) and, when it occurred, the fracture line was located at the base of the connection (17). Testori T, Galli F, Fumagalli L, Capelli M, Zuffetti F, Deflorian M, Parenti A, Del Fabbro M. Assessment of Long-Term Survival of Immediately Loaded Tilted Implants Supporting a Maxillary Full-Arch Fixed Prosthesis. 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). 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. Additional zirconia implant systems are the CeraRoot system (Oral Iceberg, Barcelona, Spain), the ReImplant system (ReImplant, Hagen, Germany), the White Sky system (Bredent Medical, Senden, Germany), the Goei system (Goei Inc, Akitsu-Hiroshima, Japan), the Konus system (Konus Dental, Bingen, Germany), the Z-systems (Z-systems, Konstanz, Germany), and the Ziterion system (Ziterion, Uffenheim, Germany). This implant shape, however, does not dissipate well the oblique forces that are concentrated at the implant apex and neck. J Prosthodont Res 2018 Oct;62(4):397-406. These realities imply a high risk for fracture.11 In recent years, high-strength zirconia ceramics have become attractive as new materials for dental implants. Malo P, de Araujo Nobre M, Lopes A, Moss SM, Molina GJ. 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. ... Zirconia … To reduce the presence of a micro-gap, some implants have a designed space at the implant-abutment juncture which is created to form a hermetic seal. Does sinus floor elevation in the presence of Schneiderian membrane pathology increase therisk of membrane perforation and implant failure rate? The results of these treatments not only determine a rough thread, but also allow to achieve an optimal degree of roughness at microscopic and macroscopic level (2-3 μ) (26). At 3 months, it was observed that implant surface morphology strongly influenced the rate and the modality of peri-implant osteogenesis. Full-arch implant rehabilitation techniques use a minimum of four implants per arch to treat complete edentulism. J Dent Res. 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). Clin Oral Implants Res 2009;20 (Suppl. Internal cone connection (Z3c Z-Systems AG, Oensingen, Switzerland; SDS® 2.0, SDS Swiss Dental Solutions AG, Kreuzlingen, Switzerland). 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. Scarano et al30 demonstrated the bone response to zirconia implants at 4 weeks. Clin Implant Dent Relat Res 2012;14:e139-50. However, no differences were observed between the zirconia groups and SLA titanium at 6 and 12 days. The recommended maximum tightening torque is not to exceed 25 Ncm and, as previously stated, it is recommended to use the screw only once. Furthermore, zirconia particles used for surface modifications of titanium implants may have the potential to improve initial bone healing and resistance to removal of torque. The growing demand for metal-free restorations even for complex treatments, such as full-arch restoration in edentulous patients, spurred research on alternatives such as zirconia implants. Only three mandibular teeth were present (Figure 17) with no teeth remaining in the left quadrant and moderate to advanced vertical bone loss. Insertion torque value for all implants was in the range of 20 to 25 Ncm and all implants showed good clinical primary stability. However the authors have observed the above-mentioned incidents clinically in private practice. Internal multi-lobe connection (NobelPearl, Nobel. However, it is important to underline that while both treatments improve the maintenance of osseointegration they do not increase its speed: it is not possible to establish which of the two treatments has a greater effect on bone growth. Buczynski BW, Kory MM, Steiner R, Kittinger TA, Ramsier RD. However, one of the mandibular implants failed to osseointegrate and was removed two months after placement. However, compared to the single-piece implant, the two-piece ceramic implant systems can potentially undergo similar complications observed in titanium implants. Zirconia implants have enabled modern implantology to overcome the limitations of titanium, which are not just in terms of restoration, such as the anterior quadrant in patients with thin gingival biotype, but also in terms of immunological response to the implant material. 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. Regarding studies on two-piece zirconia implants, the results obtained in terms of implant success and survival have shown data comparable to those of titanium implants. Sennerby L, Dasmah A, Larsson B, Iverhed M. Bone tissue responses to surface-modified zirconia implants: a histomorpho- metric and removal torque study in the rabbit. Zirconia vs. titanium implants Originally the first dental implants (1980’s) had two parts: the fixture (which goes screwed into the bone) and the abutment (where the prosthetic crown is cemented). Clin Implant Dent Relat Res. Zirconia bioceramic composites have emerged as reliable and predictable alternative implant materials. Since patients have increasingly become knowledgeable, sophisticated and health conscious, there has been a rise in requests for metal free alternatives of teeth replacement. No significant difference was observed between the hardness of all coatings and substrates. 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. Akagawa et al27 examined the initial implant-bone interface with the 1-stage zirconia screw implant (Goei Industry, Akitsu-Hiroshima, Japan) with different occlusal loading conditions after 3 months in beagle dogs. 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°. 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. 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. Adhesive, morphologic, and structural properties of the plasma-sprayed coatings were evaluated. In the last study conducted by this group,2 the osseous healing of zirconia implants (Konus) was compared with that of acid-etched titanium implants with the same macroscopic design in an animal experiment. Optimal osseointegration of Zirconia Implants without any signs of inflammation or foreign body rejection. The highest values for BIC, bone ingrowth, and Vickers hardness were measured in implants sandblasted with zirconia particles, which have higher surface roughness (arithmetical mean roughness [Ra]: 1.52 µm, maximum peak [Rt]: 12.06 µm, and ten-point mean roughness [Rz]: 11.54 µm), followed by zirconia sandblasted implants with lower surface roughness (Ra: 1.32 µm, Rt: 8.76 µm, and Rz: 8.86 µm). Immediate dentures were fabricated and duplicated to make a surgical guide. 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. The manufacturer surgical protocol was closely followed. 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. 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. At 12 weeks, ultrastructural evidence of successful osseointegration of both implant systems was found. Clin Oral Impl Res 2007;18:496-500. Franchi et al22 evaluated peri-implant tissues of zirconia-coated titanium implants and acid-etched titanium implants by light microscopy. Clin Implant Dent Relat Res 2003;5:2-9. (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.

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). Titanium and titanium alloys are widely used for fabrication of dental implants. As with titanium implants, the same implant morphological principles apply to implants in zirconia. Since the decementation of an implant is a not infrequent complication, even for two-piece implants, the abutment may become detached from the implant owing to decementation. Zirconia is very compatible with the human body and began being used in hip replacements before its introduction into dentistry. Because of this one-piece design, they are often easier to handle and offer a relatively seamless option for surgeons who want to place the implant and then continue on with the crown procedure itself. Additionally, the increasing aesthetic demands from patients, particularly for their anterior teeth, shows that failing to achieve a highly aesthetic restoration ultimately means an overall unsuccessful result, despite having functional success. A recent review of the literature conducted by Haro Adánez Mireira et al. The operative phases concerning the cementation are very simple, which means it can be used even by less experienced operators. These issues occur at the implant-abutment interface owing largely to the greater risk of bacterial colonization in the micro-gap that can be created at the abutment-implant connection (11). The same protocol was followed for the mandibular implants and four implants were placed with similar insertion torques and primary stability observations. Clin Oral Implants Res 2015;26(4):371–6. However, it does not have an anti-rotational function and can lead to serious complications in the event of fracture. This material is not radiopaque, with an elastic modulus >160 GPa, flexural strength >1100 MPa, tensile strength 2000 MPa and is biocompatible according to ISO10993.

Minerva Stomatol 2003 Mar;52(3):111-21. 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. All on 4 implant reviews are good but as stated complications do arise. Because of potential immunologic and possible esthetic compromises with titanium implants, novel implant technologies are being developed. Although a few short-term clinical reports are available and provide satisfactory results, controlled clinical trials with a follow-up of 5 years or longer should be performed to properly evaluate the clinical performance of zirconia implants and to recommend them for routine clinical use. 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. These materials have attained mainstream use because of their excellent biocompatibility, favorable mechanical properties, and well documented beneficial results.2,3 When exposed to air, titanium immediately develops a stable oxide layer, which forms the basis of its biocompatibility. This occurs not only in situations where the bone does not have sufficient density at the time of implant placement, but also in sites where prior or simultaneous regenerative procedures such as  GBR, sinus lift, trans-sinus lift have been carried out. snap on implant dentures. Zirconia seems to be a suitable implant material because of its toothlike color, mechanical properties, biocompatibility, and low plaque affinity. Dent Mater 2018 Sep 1. pii: S0109-5641(18)30475-5. No bleeding was detected on probing. Kohal et al43 evaluated the fracture strength of titanium implants with metal-ceramic crowns, zirconia implants with Empress I crowns, and zirconia implants with Procera (Al2O3 based) crowns before and after exposure to the artificial mouth. J Oral Implantol 1 June 2011; 37 (3): 367–376. Clin Oral Implants Res 2013 May;24(5):569-75. Gahlert M, Gudehus T, Eichorn S, Steinhauser E, Erhardt W.

Aluminium oxide (Al2O3) was one of the first ceramic materials used for implants. Influence of glycemic control on survival of zygomatic implants in relation with type-2 diabetes mellitus: 10 years’ follow-up results, Role of probiotics for the treatment of peri-implant mucositis in patients with and without type-2 diabetes mellitus. D. Duddeck,  J. Neugebauer. The search for biocompatible materials as an alternative to titanium for dental implants has led dentistry to the use of innovative materials that can overcome some of the issues observed with titanium. 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. Using more sophisticated and sensitive diagnostic methods, such as LTT lymphocyte transformation tests, it has been possible to reveal immunological reactions in patients exposed to titanium implants (3) at even higher percentages. Fretwurst, T., Nelson, K., Tarnow, D. P., Wang, H.-L., & Giannobile, W. V. (2018). Kohal et al45 observed the stress distribution patterns of zirconia implants (ReImplant), which were found to have low, well distributed, and similar stress distribution compared with titanium implants. Almeida EO, Freitas Jr AC, Bonfante EA, Marotta L, Silva NRFA, Coelho PG. The Italian Journal of Dental Medicine is published quarterly. 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.
