“…Accordingly, piezosurgery facilitates both socket preparation and atraumatic extraction of third molars 23 . Different approaches integrating digital planning and 3D printing technologies have been proposed to update and simplify the surgical technique to achieve better outcome rates for this technique 14,24 . However, free‐hand preparation of the donor site is still required.…”

Objective Tooth autotransplantation with a complete root formation to replace one or more lost teeth is indicated as a cost‐effective alternative to implants. The aim of this case report was to describe a successfully guided autotransplantation of a maxillary third molar with fully formed roots into a surgically created socket after orthodontic space opening. Clinical considerations A guided autotransplantation of the maxillary left third molar into the missing maxillary left first molar site was chosen. After virtually orientating donor tooth to confirm its optimum fit, it was deemed necessary to open 4 mm the mesiodistal space. Following the orthodontic movement, a 3‐dimensional (3D)‐guiding template and a milled surgical guide were manufactured to allow the donor tooth to be transplanted exactly in the planned position. The 2‐year follow‐up periapical radiograph showed a continuous periodontal space with no signs of apical periodontitis or root resorption. Conclusions Virtual planning and 3D‐printed tooth replica combined with guided surgery can simplify the autotransplantation technique for both the clinician and the patient, particularly when the socket has been completely created during surgery. Clinical significance Virtual digital planning, which can accurately calculate the exact space to open orthodontically before an autotransplantation, could prove essential to enhancing the precision of 3D placement of the donor tooth in the recipient site.

Auto transplantation is a fast and economical option when a suitable donor tooth is available for replacement of a tooth considered impossible to treat. The purpose of this case report is to describe methods used for autotransplantation and its advantages for cases with a missing bilateral mandibular firstmolar, as compared with a dental implant, removable partial denture, and other methods of prosthesis. In the present patient who underwent auto transplantation, clinical and radiographic outcomes were considered satisfactory at one and two years postoperatively. Bone healing was observed around the roots of transplanted teeth, which showed good function. In autotransplantation cases, even when the donor tooth has complete root formation, a high success rate can be achieved when the patient is properly selected and treated. Although the chance of root resorption remains because of necrotic pulp and periodontal irritation during manipulation, auto transplantation should be considered as a good treatment modality in feasible cases. Based on the present findings, even though autotransplantation is not common in general dental practice, we consider that it offers a clinically and economically viable alternative as compared to other more complicated prosthetic and dental implant treatments. The purpose of this report is to show that auto transplantation is a superior treatment method for single molar defects as compared to other prosthetic methods, as the periodontal ligament of the patient can be used and cutting adjacent teeth is avoided. In addition, it is a treatment method that can effectively utilize a wisdom tooth.
