Abstract
ABSTRACT Tooth autotransplantation is an option for treating patients presenting early tooth loss. The teeth most commonly removed are the first molars, and their absence could lead to several oral health problems in patients. This transplant technique consists of the transposition and repositioning of a tooth from one area to another, in the same patient. Dental implants have high success rates, but tooth autotransplantation is less complex and less expensive, because the patient’s own tooth is used. In the context of dental rehabilitation, tooth transplantation is focused on re-establishing masticatory function and esthetics. Success rates are variable, but in the majority of cases they exceed 80%. This article aims to report the case of a patient who underwent autotransplantation of the maxillary left third molar into the maxillary right first molar position. The surgical procedure was performed on two stages. After a 3-year clinical and radiographic follow-up period, a satisfactory result was achieved with the transplanted tooth presenting a healthy pulp and periodontal tissues, reestablishing the patient’s function and esthetics.
Highlights
The first permanent molars are the teeth in the oral cavity that are most frequently lost, because they are the first permanent teeth to erupt [1,2] and are often the teeth most frequently extracted in patients at an early age
A treatment option for patients presenting absence of the first molars, or an unfavorable prognosis for their maintenance, is tooth transplantation. This technique consists of the transfer of a tooth from one site to another, in the same person [4-6]
The cost of performing transplantations must be considered, since it is lower than that of rehabilitation with implants, or even with dental prostheses, because no high cost materials are used[9,22]. Another option for the treatment of tooth loss is the use of dental prostheses, transplantation of the natural tooth has the advantage of impeding alveolar bone resorption; promoting its formation[13], and preserving its volume and morphology[23]
Summary
The first permanent molars are the teeth in the oral cavity that are most frequently lost, because they are the first permanent teeth to erupt [1,2] and are often the teeth most frequently extracted in patients at an early age The absence of this tooth may lead to migration of adjacent teeth, making it difficult to perform later rehabilitations [3]. A treatment option for patients presenting absence of the first molars, or an unfavorable prognosis for their maintenance, is tooth transplantation This technique consists of the transfer of a tooth from one site to another, in the same person (autogenous tooth transplantation or dental autotransplantation) [4-6]. This autotransplantation procedure enables a compromised or absent tooth to be replaced by a transplanted tooth For this purpose, impacted third molars are generally used, and they would be transferred to a prepared or existent alveolus. This treatment is indicated for patients with congenitally absent teeth, in cases of traumatisms, iatrogenic events or when it is unfeasible to perform prosthetic restoration [3]
