“…1 A method for autotransplantation of immature premolars was described in 1967 and 1974 by Slagsvold and Bjercke. 2,3 High initial success rates 2,[4][5][6][7] and also long-term results are reported. [7][8][9][10] The most common complications associated with autotransplanted teeth are ankylosis and root resorption.…”

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.)

“…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]. In fact, replacement resorption (ankylosis) may be evident only 3-4 months to 1 year after the procedure, whereas inflammatory may take about 3-4 weeks to become evident [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”

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 periodontal response can though be greatly influenced by the preoperative periodontal status and maintenance of good oral hygiene habits in the postoperative period (Kewitt and Van Sickels, 1999;Mommaerts et al, 2005). Andreasen et al (1990) defined periodontal healing by ''a newly formed PDL space surrounding the entire root periphery.'' In this investigation, not yet-well organized connective tissue between the distraction callus and the damaged root surface was observed.…”

SUMMARY. Aim: The objective of the study was to evaluate the impact of dental lesions on the periodontium, in a canine model of mandibular osteodistraction. Material and methods: In six adult male Beagle dogs, an osteotomy was made between the right second lateral incisor and canine, and a distraction device placed. The roots adjacent to the osteotomy were deliberately damaged by the reciprocating saw and chisel, with preservation of the attached gingiva. The osteodistraction protocol used was: latency of 7 days, rate of distraction 1 mm per day, and rhythm once a day for 5 days. Vital staining was carried out with tetracycline, Xylenol Orange and Calcein Green. The dogs were sacrificed after 12 weeks of consolidation and the specimens were evaluated with light microscopy (native, polarized light, fluorescence, and after toluidin blue staining). Results: The periodontal ligament (PDL) regeneration was observed in the 2500 slices examined. Cementum and dentine lesions were repaired by cellular cementum. Loose dentine and cementumedentine fragments were embedded in regenerated PDL and their surface repaired by cementum. By means of light microscopic examination and within the limited observation time, no degenerative pulpal changes were found, when the pulp canal was not entered. Extensive pulp exposure and destruction resulted in ingrowth of the PDL and bone-like tissue. In that case, cellular cementum also lined the dentine surface of the pulp canal. Conclusion: Although there was an extensive reparative response to the para-pulpal lesions, none of the changes observed showed evidence of a loss of functional integrity of the periodontium at the distraction site. The fate of the tooth with exposed pulp canal remains uncertain. Ó 2008 European Association for Cranio-Maxillofacial Surgery
