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

Abstract

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.

Influence of Sagittal Root Positions on the Stress Distribution Around Custom-made Root-analogue Implants: A Three-dimensional Finite Element Analysis

“…RAIs are de ned as implants that have the same contour as the extracted root [2,3]. Compared to traditional implants, RAIs have some advantages, such as a better t in the extraction socket, eliminating the need for conventionally used bone drills and other traumatic procedures that are required to prepare for implantation, as well as uncomplicated immediate implant placement, increased patient comfort, and better aesthetic effectiveness through immediate temporary restoration [1,[4][5][6][7][8].…”

“…Although many researchers had reported many successful clinical cases using RAIs in the past years [6,9], there have been some failures [8,10]. Research has shown that stress distribution in the bone around implants under loading is related to the success of implantation [11].…”

Clinical Outcomes of Root-Analogue Implants Restored with Single Crowns or Fixed Dental Prostheses: A Retrospective Case Series

“…Studies on root-analogue implants and potential advantages appear repeatedly in the literature. As the procedure is not established in clinical routine, only case reports with different follow-up intervals [ 14 , 15 , 16 , 17 , 20 , 22 ] or literature reviews exploring the subject [ 33 ] are available. Recently, an article reviewing the historical development of RAIs was published [ 34 ].…”

Customized Root-Analogue Implants: A Review on Outcomes from Clinical Trials and Case Reports

“…Titanium remains still as “the gold standard” metallic material for dental implants. However, an increased concern with aesthetical issues has led to an increased interest in ceramic materials, namely zirconia, for such applications [ 12 ]. Apart from its tooth-like colour, its high corrosion resistance, biocompatibility and high wear resistance make zirconia a promising material for dental implants [ 13 ].…”
