“…6 Splitting osteotomy of the alveolar process has a negative influence on pulpal revascularization and also seems to exert a negative effect on postoperative root growth of transplanted immature third molars. 26 Adequate mesiodistal and vertical space is required at the recipient site. In the present study, the teeth were most frequently transplanted to recipient sites that lacked buccal and lingual alveolar bone, as illustrated in Figure 1B,C.…”

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.)

“…Therefore, we can assume that the thermoplastic retainer was effective for the protection transplanted teeth against early occlusal and lateral forces, especially those transplants with poor stability. The available literature describes many different stabilization techniques for transplanted teeth, including fixation with orthodontic brackets, ligature wires, acidetch composites, and sutures (1,5,6). The stabilization period for transplanted teeth varies between one and 4-6 weeks (6).…”

“…Moreover, use of a rigid splint has shown a negative influence on the revascularization of the pulp. There are many reports which have advised a suture splinting period of 7-10 days, but this technique was proposed only in cases with good primary stability, while rigid fixation for 4 weeks is seen in cases with poor initial stability (6,7). In contrast to these techniques, Akkocaoğlu et al (5) indicated that autotransplantation of teeth without primary splint stabilization was a reliable treatment.…”

“…However, this technique can only be used when transplants have good stability and sufficient mesiodistal width. Sometimes (especially when primer retention cannot be achieved) splinting is obligatory when transplants are small according to mesiodistal size (6). Considering that splinting is necessary for many transplants, especially cases with poor stability, as well as the disadvantage of rigid spIints, we used removable, non-rigid splints in the present study.…”

Objective: Different fixation techniques have been used for stabilization of autotransplanted teeth. Because rigid or extended fixation periods can cause complications such as ankylosis and disturbances of pulpal revascularization, our aim was to evaluate an alternative technique, a removable splint, for improving the success rate of autotransplanted molar teeth. Study Design: In 44 patients, (20 male and 24 female patients), 45 transplanted teeth were analyzed. These cases were followed for 31 to 47 months after operation. Transplanted teeth were evaluated after use of a thermoplastic retainer for 1 month, in terms of success rate and dissatisfaction with this apparatus. The primary stability, ankylosis, and root resorption were also analyzed. Results: To date, 1 transplant was extracted after 6 months due to unpreventable periapical root inflammation, and 2 transplants were extracted after one year due to external root resorption. Although 2 ankylosed transplants were still functional after an average follow-up period of three years, with no dissatisfaction by the patients, these cases were treated as failures because of the probable risk for external root resorption. The remaining 40 (88.8 % success rate) transplants remained asymptomatic and functioning for a mean follow-up period of 37 months. In the assessment of dissatisfaction with the thermoplastic retainer, 36 (81.8 %) patients had no or little dissatisfaction, 4 (9 %) patients had very appreciable or excessive dissatisfaction, and 4 (9 %) patients had moderate dissatisfaction. Conclusions: A thermoplastic retainer for use after autotransplantation of third molar teeth is a reasonable and useful method and a good alternative to conventional rigid or semi-rigid splints. This technique was especially useful in autotransplanted teeth that had poor stability, i.e., in cases in which it is conventionally advised to use long-term rigid or semi-rigid splints.
