Autotransplantation of premolars and space closure in a patient with inflamed sinuses

A new era in modern dentistry has emerged where tooth loss is no longer an issue as a result of rapid advancements in implantation and alveolar ridge reconstruction. Despite its wide range of indications, autotransplantation is dependent upon careful patient selection and a suitable technique to ensure successful results both functionally and aesthetically. It is possible to restore physiological occlusion, aesthetics, and masticatory function by varying implant length, diameter, surface, and design, along with autogenous, alogenous, alloplastic, or xenogenous bone substitutes. However, none of the technologies that are used in implant dentistry today can adapt to a child's growing jaw during adolescence. Thus, the young age of the patient restricts implants and creates a challenge for dentists wishing to replace missing teeth. Therefore, tooth autotransplantation can be a good option for treatment. Our objective in this review is to highlight the biological principles required for the successful autotransplantation of teeth. Limits, indications, and prognoses will be analyzed. Hopefully, with increased awareness and acceptance in the dental profession, autotransplantation will become another viable treatment option for those with compromised teeth who still have significant growth potential.

“…utotransplantation of teeth offers a unique treatment option, especially when this is combined with orthodontic treatment. 1,2 Many orthodontic patients in which anterior or posterior teeth have to be extracted replace a missing tooth with a natural tooth rather than with a dental implant or bridgework. 3,4 The advantage of tooth transplantation, unlike dental implants, is that transplanted teeth have living periodontal ligaments.…”

This case report describes the successful orthodontic treatment of a 12-year-old girl with skeletal Class III malocclusion and severe root resorption of the maxillary anterior teeth. Ectopic eruption and mesial inclination of the bilateral maxillary canines caused severe root resorption of the right central and lateral incisors and the left lateral incisor. These 3 teeth were extracted, and traction was applied to the maxillary right and left canines toward the extracted right central incisor and left lateral incisor, respectively. In the mandibular arch, the bilateral first premolars were extracted, and the crowding was corrected. The extracted mandibular right first premolar was transplanted after extraction of the maxillary right lateral incisor. To prepare for the tooth transplantation, a cone-beam computed tomography image was used to fabricate a 3-dimensional printed replica of the donor tooth. The crown shape of the maxillary anterior teeth was corrected, and the patient achieved functional occlusion with pleasing esthetics. Root resorption was negligible in the transplanted tooth. This study demonstrates the satisfactory treatment outcome and an effective 3-dimensional simulation for tooth transplantation.

Background/AimThis study aims to evaluate the precision and efficacy of utilizing computer‐aided design (CAD) in combination with three‐dimensional printing technology for tooth transplantation.Material and MethodsThis study analysed 50 transplanted teeth from 48 patients who underwent tooth transplantation surgery with the aid of CAD and positional guides. A consistent coordinate system was established using preoperative and postoperative cone‐beam computed tomography images. Linear displacements and angular deviations were calculated by identifying key regions in both virtual designs and actual transplanted teeth. Additionally, an analysis was conducted to explore potential factors influencing these deviations.ResultsThe mean cervical deviation, apical deviation, and angular deviation among the 50 transplanted teeth were 1.16 ± 0.57 mm, 1.80 ± 0.94 mm, and 6.82 ± 3.14°, respectively. Cervical deviation was significantly smaller than apical deviation. No significant difference in deviation was observed among different recipient socket locations, holding true for both single‐root, and multi‐root teeth. However, a significant difference was noted in apical deviation between single‐root and multi‐root teeth. Our analysis identified a correlation between apical deviation and root length, leading to the development of a prediction model: Apical deviation = 0.1390 × (root length) + 0.2791.ConclusionsThe postoperative position of the donor teeth shows discrepancies compared to preoperative simulation when utilizing CAD and 3D printed templates during autotransplantation procedures. Continual refinement of preoperative design is a crucial endeavour.
