“…It is well known that a key of a successful tooth autotransplantation is the viability of periodontal ligament cells damaged by the extraction [ 4 , 5 , 6 ]. Therefore, in Japan, the extracted tooth without root canal treatments is transplanted into the socket as soon as possible, fixed with wire or bonding, and then endodontic treatments will start within 1 month, conventionally [ 7 ].…”

“…The preservation of periodontal ligament cells is considered to be critical for the success of a transplanted tooth [ 4 , 5 , 6 ]. However, the timing of root canal treatments for donor tooth with complete roots has not been sufficiently discussed, nor well-documented [ 7 , 9 , 14 , 15 ].…”

“…On the other hand, in Korea, it seems that RCF prior to the donor tooth extraction was recommended, except for the impacted teeth or ones were the access was impossible [ 15 ]. Additionally, a unique technique was also considered and reported in India [ 6 ]. The donor tooth after intraoral RCF was extracted and put in a customized reservoir, to reduce the extraoral time during the surgery [ 6 ].…”

“…Additionally, a unique technique was also considered and reported in India [ 6 ]. The donor tooth after intraoral RCF was extracted and put in a customized reservoir, to reduce the extraoral time during the surgery [ 6 ]. In the present case, the extracted donor tooth was fixed using a newly developed device, and immediate RCF was performed in the device extra-orally, just after tooth extraction.…”

“…The survival and success rates of transplanted teeth varies, depending on the type of transplanted tooth, stage of root development of donor teeth, surgical technique, the follow-up period, and methodology of the research [ 2 , 3 ]. It is well known that the viability of the periodontal ligament cells after extraction of the donor tooth is most important aspect for the success of tooth transplantation [ 4 , 5 , 6 ]. The transplanted tooth with complete root formation is rarely expected to revascularize and reinnervate [ 7 ].…”

This clinical report describes immediate tooth auto-transplantation with an autograft of partially demineralized dentin/cementum matrix (pDDM), based on an orthodontic treatment plan for a 16-year-old male patient with a congenital missing tooth (#45). First, vital teeth (#14, #24) were extracted, and root canal filling (#14) was immediately performed with the support of a fixation device. Simultaneously, the tooth (#24) was crushed in an electric mill for 1 min, and the crushed granules were partially demineralized in 2% HNO3 solution for 20 min as the graft material. Next, the donor tooth was transplanted into the created socket (#45), and stabilized using an enamel bonding agent. The wet pDDM was loaded into the location of the congenital missing tooth, and the flap was repositioned. The bonding agent for stabilization was removed at 28 days, and also small contact points between the transplanted tooth and the upper premolar (#14) were added using photopolymerizable composite resin. X-ray photos were taken sequentially, and there were no postoperative complications. The radiographic images showed that the periodontal ligament space and alveolar ridge line could be observed at 18 months. The pDDM was harmonized with the mandible, and the remodeled bone-like shadow was observed in the graft region. We concluded that immediate tooth transplantation with root canal fillings and autogenous pDDM may be a valuable alternative to dental implanting or bridge formation for patients with a congenital missing tooth, followed by orthodontic treatment.

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.

Purpose The aim of this study was to evaluate the clinical outcome of autotransplantation of a mature third molar to a fresh molar extraction socket using three-dimensional (3D) replicas and a preoperative simulation, which includeduse of preoperative cone-beam computed tomographicy(CBCT) planning and 3D replicas of donor teeth to prepare the artificial tooth sockets. Methods Three patients underwent autotransplantation using 3D replicas and preoperative simulation. Before the procedure, the direction and depth of the donor tooth were confirmed with a computer using replica data, then a simulation was performed using the replica and the research model as pseudo-autotransplantation surgery. The replica was manufactured using a 3D printing technique. The surgical procedure was based on guided autotransplantation surgery methods associated with Andreasen’s technique. Results Based on Chamberlin's criteria for successful transplantation, all three patients had good results. The average extraoral time of the donor tooth was shortened to an average 3.33 minutes when using a 3D replica. Additionally, we previously presented a report of a case without 3D replica autotransplantation with a time of 16 minutes. Conclusions The present approach enables planning and production of a 3D printed surgical template with use of the latest diagnostic methods and guided autotransplantation surgery techniques. Autotransplantation using a 3D replicas with preoperative simulation is an effective method that can reduce extraoral time as well as periodontal ligament damage to the donor tooth, and can reduce the rate of failure.
