Dental implant fractures

: a systematic review

Abstract

Background: Dental implantology has advanced significantly since the introduction of osseointegrated implants, providing patients with esthetic and functional benefits that can greatly improve their quality of life. However, despite high success rates, failures can occur. While uncommon, implant fractures can have serious consequences for patients and implant removal is often necessary. Thus, a better understanding of this complication is needed in order to provide the best possible care for patients. Aim: The aim of this study is to review the available literature related to the implant fracture risk factors and its reported incidence. Materials and methods: A protocol based on the PRISMA guideline was used in this systematic review. An extensive research was conducted in the electronic databases PUBMED and COCHRANE, which included controlled clinical-trials and RCT´s (Randomized Controlled Trials) from the last 15 years. Results: The initial research led to 457 articles (PUBMED and COCHRANE), combined with the results of the hand search, there were a total of 624 articles. After screening, full-text assessment and application of inclusion/exclusion criteria 12 articles were selected. This review found a fracture incidence between 0% and 2% on a follow-up period of 1 - 235 months. Conclusions: Implant fractures are rare, however with severe complications. Factors such as implant location, material, design, diameter, length and prosthesis have been proposed as risk factors. Clinical significance: Identifying risk factors related to dental implant fracture can help prevent it and it´s correspondent adverse effects.
