Abstract
BackgroundIt has been reported that the load for (or to) implant-supported restoration may lead to bone remodeling as bone resorption and/or formation. While many authors supported the process of bone resorption, others elaborated bone apposition and increasing bone density close and remote to implant body (or fixture). This may suggest the role of the implant to reserve alveolar ridge from physiologic/pathologic resorption. The aim of this systematic review was to predict to how extend dental implants can preserve the residual alveolar ridge based on previous clinical investigations.MethodsThis systematic review based on the retrospective and prospective studies, randomized clinical trial, and case reports. The process of searching for proposed articles included PubMed, Ovid, and Web of Science databases, with specific inclusion and exclusion criterion.ResultsA total 2139 citations were identified. After expunging the repeated articles between databases and application of exclusion and inclusion criteria, 18 articles were found to meet the topic of this systematic review. Many of the articles reported bone preservation with implant-assisted restorations, and the rest denoted noticeable bone apposition.ConclusionAccording to the published clinical studies, the behavior of bone remodeling around implant predicts a sort of residual alveolar bone preservation.
Highlights
Edentulism is rated between 7 and 69% internationally [1]
Regardless the debate to understand the way of resorption [3], the loss of periodontal ligament by tooth extraction leaves alveolar bone without a chance of reformation which leads to bone resorption only
Rather than monitoring the bone atrophy, this review investigates the capability of the implant to be responsible for preserving residual alveolar ridge bone and the role of implant-assisted restoration to reduce the alveolar ridge atrophy
Summary
Edentulism is rated between 7 and 69% internationally [1]. Many biological and non-bilogical predisposing factors lead to the main result of edentulism [2]. The tracing of the bone resorption is difficult for the complete denture with the continuous rated atrophy of the residual alveolar ridge beneath the conventional. It has been reported that the load for (or to) implant-supported restoration may lead to bone remodeling as bone resorption and/or formation. While many authors supported the process of bone resorption, others elaborated bone apposition and increasing bone density close and remote to implant body (or fixture). This may suggest the role of the implant to reserve alveolar ridge from physiologic/pathologic resorption. The aim of this systematic review was to predict to how extend dental implants can preserve the residual alveolar ridge based on previous clinical investigations
