Long-Term Survival Rate of Autogenous Tooth Transplantation: Up to 162 Months

Abstract

Background and Objectives: The purpose of this study is to observe the usefulness of autogenous tooth transplantation by examining the cumulative survival rate according to the period of auto-transplanted teeth as pre-implant treatment. Materials and Methods: This study was conducted on 111 patients who visited Kyungpook National University Dental Hospital and underwent autogenous tooth transplantation between November 2008 and January 2021 (about 13 years). The cumulative survival rate of autogenous tooth transplantation according to the causes of extraction of the recipient tooth (caries, periapical lesion, crack, crown fracture, periodontitis) and condition of opposing teeth (natural teeth vs. fixed prosthesis). The cumulative survival rate of autogenous tooth transplantation according to the age (under 30 vs. over 30) was also investigated and it was examined whether there were any differences in each factor. Results: The average follow-up period was 12 months, followed by a maximum of 162 months. The 24-month cumulative survival rate of all auto-transplanted teeth was 91.7%, 83.1% at 60 months and the 162-month cumulative survival rate was 30.1%. There were no statistical differences between the causes of extraction of the recipient’s teeth, differences in the condition of the opposing teeth, and differences under and over the age of 30. Conclusions: The survival rate of autogenous tooth transplantation appears to be influenced by the conditions of the donor tooth rather than the conditions of the recipient tooth. Although autogenous tooth transplantation cannot completely replace implant treatment, it is meaningful in that it can slightly delay or at least earn the time until implant placement is possible.

Long-Term Evaluation of Tooth Transplantation: An Umbrella Review

“…Yanik et al found in another study that 4% of cases showed root resorption [ 5 ]. When the recipient’s immune system targets the implanted tooth’s root, root resorption takes place, which results in tooth loss [ 7 ]. The causes of failure of the autotransplant is chronic root resorption, inflammatory resorption, replacement resorption i.e., ankylosis, marginal periodontitis, apical periodontitis, caries, and trauma [ 8 ].…”

Successful Non-Surgical Root Canal Treatment on Auto-Transplanted Maxillary Premolar with Apical Periodontitis

“…Therefore, in most young patients, implant-retained restorations or fixed partial dentures are only an appropriate treatment plan in the later stages of development. For this reason, auto-transplantation can successfully replace congenitally missing teeth and teeth lost to trauma or caries in young adolescent patients [ 2 ]. Auto-transplanted teeth can also induce bone growth, which will continue as the patient matures and develops [ 3 ].…”

“…Auto-transplanted teeth can also induce bone growth, which will continue as the patient matures and develops [ 3 ]. When the procedure is performed correctly, success rates of revascularization are approximately 85%, and patients can expect a long-term tooth survival rate of 83–98% [ 2 , 4 , 5 ]. However, not all cases of auto-transplantation are successful.…”
