Abstract
Abstract
Introduction:
A dental autotransplant is a controlled case of dental avulsion based on the transplantation of erupted teeth within the same individual, from one place to another, in sites where an extraction was performed or that were surgically prepared. Autotransplantation has become a viable method to replace lost teeth since transplanted teeth may operate as fully normal teeth.
Objective:
The objective of this study was to summarize the available scientific evidence regarding predictors of success in autotransplanted teeth.
Materials and Methods:
A systematic review of systematic reviews, known as an umbrella review, was performed. Two calibrated and standardized investigators independently analyzed the quality using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline and evaluated the confidence level and bias review with the Amstar-2 guideline. The PubMed, Embase, and Scopus databases were used. The search was conducted in August 2022 and updated on March 22, 2023. Systematic reviews or meta-analyses carried out from publications on human beings, between 2017 and 2022, were included.
Results:
From 104 achieved, 4 systematic reviews and meta-analyses were assessed. The overall survival of autotransplanted teeth ranged from 81% to 98%, the prevalence of overall inflammatory root resorption ranged from 2.1% to 43%, and the prevalence of ankylosis ranged from 1.2% to 43%. Predictive factors for success identified in the literature included tooth type or root development and clinical intervention factors, including socket preparation, splinting, occlusion control, antibiotic regimen, treatment time of endodontics, and orthodontic treatment.
Conclusions:
The existing evidence on autotransplanted teeth in humans indicates that the survival rate of such teeth involves a series of presurgical and surgical variables. Analyses of factors associated with complications or failures still require primary studies where associations may be made to draw more solid conclusions.
