“…10 Therefore, some authors prefer using RAZI instead of RATI. 28 Chen at al. in their research assessed the root analog titanium implants (RATI) and the primary stability and stress distribution in the bone of root analog threaded titanium implants (RATTI).…”

“…Firstly, due to the CT/CBCT scan banks, the surgical procedure is marked by reduced treatment time and an immediate plant by 0.1-0.2 mm to diminish stress in the cortical bone and to avoid fracture of the thin alveolar bone wall. 28 Pirker et al state better esthetics (no metallic elements showing through the mucosa), enhanced mechanical (high flexural strength, hardness, fracture toughness, high electrical resistance) and chemical properties (superior plaque resistance) of RAZI. 28 A rough root surface topography (micro-and macroretentions) speeds up the osseointegration process.…”

“…30 In the presented study, RAZI was modified according to the Pirker's protocol. 28 The macroretentions were limited only to the interdental space (mesial and distal part of the root) for better primary stability and osseointegration. The buccal and lingual faces were reduced by 0.1-0.2 mm to avoid fracture and bone loss.…”

“…Fabrication of RAZI may be carried out also by scanning the extracted tooth using the laser scanner. 28 Nevertheless, using just the laser scanner has some disadvantages. If the tooth is damaged before or during the extraction, it becomes difficult to put it together and scan.…”

Custom‐made root‐analogue zirconia implants: A scoping review on mechanical and biological benefits

et al. 2018

View full text Add to dashboard Cite

The aim of this study was to conduct a literature review on the potential benefits of custom-made root-analogue zirconia implants. A PubMed and ScienceDirect bibliographical search was carried out from 1969 to 2017. The increased interest in zirconia-based dental structures linked to aesthetic and biological outcomes have been reported in literature. Recent technological advances have focused on novel strategies for modification of zirconia-based surfaces to accelerate osseointegration. However, only a few studies revealed mechanical and biological benefits of custom-made root-analogue zirconia implants and therefore further studies should investigate the influence of different design and surface modification on the performance of such implants. Custom-made root-analogue zirconia implants have become a viable alternative to overcome limitations concerning stress distribution, aesthetics, and peri-implantitis induced by biofilms. However, further in vitro and in vivo studies on surface-bone interactions and mechanical behavior of zirconia should be evaluated to reduce clinical issues regarding mechanical failures and late peri-implant bone loss. © 2018 Wiley Periodicals, Inc.

ObjectivesThe aim of this review was to evaluate the clinical success and survival rates of zirconia ceramic implants after at least 1 year of function and to assess if there is sufficient evidence to justify using them as alternatives to titanium implants.Materials and methodsAn electronic search in MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Clinical Trials (CENTRAL) databases was performed in April 2015 by two independent examiners to retrieve clinical studies focusing on the survival rate of zirconia implants after at least 1 year of function. Implant survival was estimated using the overall proportion reported in the studies with a Clopper-Pearson 95 % confidence interval (random effect model with a Der-Simonian Laird estimate).ResultsFourteen articles were selected out of the 1519 titles initially screened. The overall survival rate of zirconia one- and two-piece implants was calculated at 92 % (95 % CI 87–95) after 1 year of function. The survival of implants at 1 year for the selected studies revealed considerable heterogeneity.ConclusionsIn spite of the unavailability of sufficient long-term evidence to justify using zirconia oral implants, zirconia ceramics could potentially be the alternative to titanium for a non-metallic implant solution. However, further clinical studies are required to establish long-term results, and to determine the risk of technical and biological complications. Additional randomized controlled clinical trials examining two-piece zirconia implant systems are also required to assess their survival and success rates in comparison with titanium as well as one-piece zirconia implants.Clinical relevanceZirconia implants provide a potential alternative to titanium ones. However, clinicians must be aware of the lack of knowledge regarding long-term outcomes and specific reasons for failure.
