Abstract

BackgroundThe aim of this study was to evaluate the clinical outcome of autotransplantation of mature third molars to fresh molar extraction sockets using 3D replicas.MethodsTen patients underwent teeth autotransplantation with or without GBR. We observed the mobility, percussion, radiography examination, the probing depth and the masticatory function of the transplanted teeth during 2 years following up, which were transplanted into fresh molar sockets by using 3D replicas, and GBR when it is necessary.ResultsThe average extra-oral time of donor tooth had been shortened to 1.65 min when used the 3D replica. Some probing depth of the transplanted tooth were deeper than 3 mm at 4 or 5 weeks temporarily. And one patient felt slight sensitive when chewing with soft food at 4 weeks, then disappeared. The clinical examination of the autotransplantation teeth during 1 year follow-up showed no sign of failure.ConclusionsThe tooth autotransplantation using 3D replica with or without GBR is an effective method which can reduce the extra-oral time of the donor teeth and may result in less failure.

Highlights

The aim of this study was to evaluate the clinical outcome of autotransplantation of mature third molars to fresh molar extraction sockets using Three Dimensions (3D) replicas
Retrospective, we evaluated 10 patients (8 male and 2 females, mean age 31.6 + 8.75, range from 19 to 42 years) who underwent transplantation of their third molar to their fresh first or second molar extraction socket, using a 3D replica
Transplantation of the mature impacted tooth to compromised molar which was in the same region occurred in six cases, the other were in different region

Summary

Introduction

The aim of this study was to evaluate the clinical outcome of autotransplantation of mature third molars to fresh molar extraction sockets using 3D replicas. Percussion, radiography examination, the probing depth and the masticatory function of the transplanted teeth during 2 years following up, which were transplanted into fresh molar sockets by using 3D replicas, and GBR when it is necessary. Conclusions: The tooth autotransplantation using 3D replica with or without GBR is an effective method which can reduce the extra-oral time of the donor teeth and may result in less failure. The tooth autotransplantation is a predictable method to replace a tooth that needs to be extracted due to caries, trauma, or tooth fracture Since it was first introduced by Fauchard in his book, Le Chirurgien Dentiste, in 1728, the clinical protocol had been developed for hundreds of years [1,2,3]. Many factors affect the success of tooth autotransplantation, such as the stage of root development, surgical trauma, the recipient site (local inflammation, alveolar bone volume and quality), the surgery procedure
