Objective: To evaluate the success rate of autotransplantation of teeth in consecutive patients and to analyze factors affecting the outcome. Materials and Methods: The subjects consisted of 215 consecutive patients (101 women and 114 men; aged 9.1-56.4 years, median age 15.2 years [P 10 5 11.4, P 90 5 19.7]) who had undergone transplantation of a total of 269 teeth, all by the same surgeon. In patients with multiple transplants, only the first transplant was included, to ensure that all transplanted teeth were independent units. The transplants were recorded as unsuccessful if the tooth had been extracted or was surviving but with root resorption or ankylosis. The interval between transplantation and final follow-up was a median 4.8 years (P 10 5 2.0, P 90 5 5.5) for successful transplants and a median of 2.4 years (P 10 5 0.4, P 90 5 7.7) for unsuccessful transplants. Results: One-hundred seventy-five (81%) of the transplantations were recorded as successful and 40 (19%) as unsuccessful. Twenty-five teeth had been extracted and 15 had survived but did not fulfill the criteria for success. Conclusions: The success rate of 215 consecutively transplanted teeth was 81%. The highest success rate was for transplantation of premolars to the maxillary incisor region (100%).Complications at surgery such as difficult extraction, deviant root anatomy, or damaged root periodontium affected the outcome. During growth, a successful transplant preserves alveolar bone. (Angle Orthod. 2010;80:446-451.)

“…It must be recognized, however, that not only will the intact and vital PDL be attached to the root surface but also PDL attachment to the bony walls of the recipient sockets play an important role in healing [24]. It is desirable to extract a tooth with as much as PDL attached to it as possible, even though the cementoblast layer by itself seems to be effective in preventing root resorption [24][25][26][27][28]. Attention was paid during the plantation not to damage the periodontal ligament of the donor tooth by pushing it into the recipient site.…”

“…Attention was paid during the plantation not to damage the periodontal ligament of the donor tooth by pushing it into the recipient site. A summary of factors contributing to successful transplantation is presented in Table 3 [24][25][26][27][28]. Complete periapical healing and periodontal health are one of the most reliable methods of prognosis and success because slight external root resorption is often not radio graphically detectable [29].…”

Auto Transplantation of a Mandibular Third Molar with Complete Root Development - A Case Report?

Autogenous transplantation is an economical as well as the most sorted option for the treatment of badly destroyed teeth when a suitable donor tooth is available. This paper presents successful auto transplantation of a mature mandibular right third molar (48) without anatomical variance is used to replace a grossly decayed mandibular right first molar (46). The mandibular first molar was nonrestorable due to extensive root caries. After extraction of mandibular first molar, root canal therapy was done for the third molar extraorally, and the tooth was reimplanted into the recipient site. After 1.8 years, clinical and radiographic examination revealed satisfactory outcome with no signs or symptoms suggestive of pathology. In selected cases, autogenous tooth transplantation, even after complete root formation of the donor tooth, may be considered as a practical treatment alternative to conventional prosthetic rehabilitation or implant treatment. IntroductionAuto transplantation of teeth has been done for many years but with varying degrees of success. It is considered as an alternative treatment for a single tooth oral rehabilitation and it is possible that it becomes more frequent if the technique respects the protocol to be followed. Auto transplantation is defined as the transplantation of embedded, impacted or erupted teeth from one site into the extraction sites or surgically prepared sockets in the same person [1]. Auto transplantation of tooth ensures maintenance of alveolar bone volume by physiological stimulation of the periodontal ligament (PDL). Recently, auto transplantation has begun to gain attention again, most likely because of the research on PDL healing after auto transplantation has provided helpful information that can be applied to the procedure [2,3]. Transplantation has a key role in the replacement of young patients missing teeth [4]. Osseointegrated implants are generally contraindicated for young patients with developing alveolar bone because infraocclusion results when the implant fails to form alveolar bone. Since the procedure causes bone and dental implant material to be fused together, the implant does not erupt along with the adjacent teeth, so the placement of dental implants may be avoided in young adolescent patients. Because of this tooth auto transplantation, which maintains the PDL, will continue to be a suitable and attractive option in many cases for replacing missing units [5]. Successful tooth transplantation offers improved esthetics, arch form and dentofacial development, mastication, speech and arch integrity. A transplanted third molar also maintains a natural space, with little or no root resorption [6], alveolar bone volume 4, 7 and the morphology of the alveolar ridge through proprioceptive stimulation [4][5][6][7][8]. The outcome of this procedure depends on careful case selection and understanding of the biological principles. Teeth traditionally selected for this procedure are impacted maxillary canines that play an important role in dentofacial esthetic...

“…The more root formation the greater the chances of root resorption and the poorer pulpal healing. 7,8 A single prophylactic dose of an appropriate antibiotic such as amoxicillin should be given to cover the operative procedure. This may be given orally one hour pre-operatively or intravenously during the procedure.…”

“…The longer the time the donor tooth spends in an extra-alveolar environment the poorer is the post-operative healing. 7,8 Either an artificial root or a similar unwanted tooth extracted at the same visit (for example the contralateral tooth) should be used as a template if possible. Where there is an excellent fit of the transplanted tooth in the recipient socket it can be held in position by running a suture over the incisal/occlusal surface from buccal to lingual gingiva.…”
