Tsukiboshi Y. Digital Simulation and Designing of a Novel Osteotomy Guide for Autotransplantation in the Anterior Region. Dent Traumatol 2024. [PMID: 39318182 DOI: 10.1111/edt.12994] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2024] [Revised: 08/24/2024] [Accepted: 08/27/2024] [Indexed: 09/26/2024]
Abstract
Autotransplantation of teeth (ATT) is a viable treatment option for replacing teeth lost due to various reasons. Periodontal ligament (PDL) on the donor tooth is one of the most crucial factors determining the success of ATT. To preserve the PDL during surgery and improve the success rate of ATT, digital dentistry has been applied to ATT. In this article, a digital workflow including surgical simulation, a three-dimensional (3D) replica fabrication, and a novel osteotomy guide design is introduced. Digital simulation of ATT on a patient's integrated model enables visualization of anatomical structures and the 3D position of the donor tooth prior to the actual surgery. The 3D-printed osteotomy guide allows the transfer of the direction and depth of the planned osteotomy into the intraoral environment. The 3D replica helps prepare the recipient site before the actual transplantation, which minimizes the extra-alveolar time of the donor tooth and decreases trauma during the try-in process. The proposed virtual planning and the use of the guide and the 3D replica can facilitate the surgical procedures while minimizing complications.

An evaluation of 910 premolars transplanted in the anterior region-A retrospective analysis of survival, success, and complications. Dent Traumatol 2024; 40:22-34. [PMID: 37731296 DOI: 10.1111/edt.12887] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 08/23/2023] [Accepted: 08/31/2023] [Indexed: 09/22/2023]
Abstract
AIM The aim this retrospective analysis was to evaluate the survival, success and possible complications of transplanted premolars to the anterior region subdivided in development stage and patient's age. MATERIALS AND METHODS The material comprised patients that underwent a tooth transplantation between April 2004 and December 2021. A total of 910 premolars were transplanted in 707 patients. Tooth mobility, oral hygiene, and periodontal parameters were clinically evaluated. Standardized radiographs were used to evaluate pulpal and periodontal healing and root formation. The cumulative survival rate was calculated using the Kaplan-Meier method. RESULTS The data were subdivided in three groups based on the stage of root development and patient's age. The average age at surgery was 16 years. The main indication for transplantation was trauma, followed by agenesis and other indications. Two premolars were lost during the whole observation period. The overall survival and success in the immature premolars group after an observation period of 10 years was 99.8%. The 10-year survival and success rate when fully developed premolars were transplanted in the anterior region in adolescents were 100% and 96.3%, respectively. In adults, the 10-year survival and success rate were 87.5%. CONCLUSION Transplantation of premolars with developing and fully developed roots to the anterior region in children, adolescents, and adults is a predictable treatment modality.

Abstract
Tooth autotransplantation is the technique of transplanting embedded, impacted or erupted teeth from one site into another in the same individual. It is relatively common for the anterior segment of the mouth to be affected by traumatic tooth injuries, impacted and/or congenitally missing permanent teeth. Autotransplantation of teeth into the anterior dental arch can provide unrivalled biological solutions when such issues arise in this critical aesthetic zone, particularly for adolescent patients. The combination of meticulous pre-surgical assessment, synergistic interdisciplinary collaboration and carefully performed anterior tooth autotransplantation has been demonstrated to achieve impressive outcomes, with respect to both transplant survival and clinical success. © 2023 Australian Dental Association.

Abstract
Tooth autotransplantation is a versatile procedure with several clinical applications among patients across different age groups. The success of this procedure depends on multiple factors. Despite the wealth of studies available, no single primary study or systematic review is able to report on every factor affecting the outcomes of autotransplantation. The aims of this umbrella review were to evaluate treatment-related and patient-related outcomes of autotransplantation and to assess the pre-, peri- or post-operative factors that could affect these. An umbrella review was conducted according to the PRISMA statement. A literature search of five databases was performed up to 25 September 2022. Systematic Reviews (SR) with and without meta-analysis evaluating autotransplantation were included. Calibration among reviewers was carried out prior to study selection, data extraction and Risk of Bias (RoB) assessment. Study overlap was calculated using corrected covered area. Meta-meta-analysis (MMA) was performed for suitable SRs. The AMSTAR 2 critical appraisal tool was used to evaluate the quality of evidence. Seventeen SRs met the inclusion criteria. Only two SRs were suitable for conduct of MMA on autotransplantation of open apex teeth. The 5-year and 10-year survival rates were >95%. A narrative summary on factors that could affect autotransplantation outcomes and comparisons of autotransplantation to other treatment options were reported. Five SRs were rated as 'low quality' and 12 SRs were rated as 'critically low quality' in the AMSTAR 2 RoB assessment. In order to facilitate a more homogenous pool of data for subsequent meta-analysis, an Autotransplantation Outcome Index was also proposed to standardise the definition of outcomes. Autotransplantation of teeth with open apices have a high survival rate. Future studies should standardise the reporting of clinical and radiographic findings, as well as the definition of outcomes.

Abstract
AIM The aim of this retrospective analysis was to evaluate the survival, success and possible complications of transplanted premolars in the posterior region subdivided by developmental stage and patient age. MATERIALS AND METHODS This study included patients who underwent tooth transplantation between April 2004 and December 2021. A total of 1654 premolars were transplanted into 1243 patients. Tooth mobility, oral hygiene and periodontal parameters were clinically evaluated. Intraoral radiographs were used to evaluate pulpal and periodontal healing, and root formation. The cumulative survival rate was calculated using the Kaplan-Meier method. RESULTS Data were subdivided into three groups based on the stage of root development and patient age. The mean age at surgery was 14.5 years. The main indication for transplantation was agenesis, followed by trauma and other indications, such as impacted or malformed teeth. A total of 11 premolars were lost during the study period. The overall survival and success rates in the immature premolar group after an observation period of 10 years were 99.7% and 99.4%, respectively. High survival and success rates (95.7% and 95.5%, respectively) were also observed when fully developed premolars were transplanted into the posterior region of adolescents. In adults, the success rate after 10-year follow-up is 83.3%. CONCLUSIONS Transplantation of premolars with developing and fully developed roots is a predictable treatment modality.

Abstract
BACKGROUND/AIMS Tooth auto-transplantation is a treatment option, which is often not considered to replace anterior maxillary incisors in children and adolescents. There are multiple prognostic factors that may influence the outcomes of premolar auto-transplantation, but there is limited evidence from human studies. The aim of this study was to report the outcomes of auto-transplanted premolars in the anterior maxilla following traumatic dental injuries (TDIs) and to identify their prognostic factors. MATERIALS AND METHODS The clinical records of patients who had premolars transplanted in the anterior maxilla following TDI, with appropriate radiographs and a minimal of 1-year follow-up, were reviewed retrospectively. A specific data extraction form was developed, tested and used to collect information for the prognostic factors and outcomes. RESULTS The cohort included 120 patients with 144 auto-transplanted premolars. The mean age was 12.2 years (±2.0), and the mean observation period was 3.7 years (±1.8). The success rate was 80%, and the survival rate was 93%. Unfavourable outcomes included external replacement resorption in 12.5%, uncontrolled external inflammatory resorption in 2.7%, and both resorption types in 4.9% of teeth. Periodontal healing was significantly associated with donor tooth root maturity, graft handling at the time of surgery including ease of donor tooth extraction and placement at the recipient sites, recipient site alveolar bone status, and post-operative transplant mobility. Seventy-four teeth (53.4%) were immature at the time of transplantation where pulp revascularisation was anticipated, and 52 (70%) of those had radiographic and clinical signs of pulp healing. Pulp healing was significantly related to donor tooth eruption stage, ease of extraction of donor tooth, and ease of placement in the recipient site. CONCLUSIONS Good outcomes were observed for premolar teeth auto-transplanted in the anterior maxilla. The main prognostic factors were ease of extraction of donor tooth and ease of placement in the recipient sites and donor tooth root maturity.

Abstract
OBJECTIVES To determine the survival of intentional autotransplantation of developing teeth. MATERIAL AND METHODS An electronic search was carried out in the MEDLINE database, Web of Science, and Cochrane Library. The criteria used are the ones described in the PRISMA Declaration. The following MeSH terms were used: ("tooth" [MeSH Terms] OR "tooth" [All Fields]) AND ("transplantation, autologous" [MeSH Terms] OR ("transplantation" [All Fields] AND "autologous" [All Fields]) OR "autologous transplantation" [All Fields] OR "autotransplantation" [All Fields]) AND ("humans" [MeSH Terms]. Randomised clinical trials and prospective and retrospective clinical studies were included. RESULTS The meta-analytic study of overall survival included a total of 14 studies, yielding an overall survival rate of 97.9%. In studies with 1-year follow-ups, survival was 98%. The resulting 2-year follow-up rate was 97%, while the 5- and 10-year survival rates were 95.9% and 96.9%, respectively. CONCLUSIONS The autotransplantation technique performed in a single-phase and on teeth that have not completed their development is a predictable technique, with a described survival rate at a 2-year follow-up of more than 97%. CLINICAL RELEVANCE The technique of dental autotransplantation is considered an important resource for the resolution and rehabilitation of tooth loss in patients, especially in those who are still in a growth period. Moreover, this technique has a low complication rate and a 10-year survival rate of 96.9%. It should therefore be considered a safe and reliable procedure.

Abstract
BACKGROUND Autotransplantation is a highly successful technique to replace ankylosed teeth. The authors propose a modified therapeutic approach to guide the autotransplant of an immature maxillary premolar using a tooth-shaped osteotome. CASE DESCRIPTION A 9-year-old boy reported an avulsion of his maxillary permanent left central incisor with a delayed replantation. An autotransplant of the immature maxillary right first premolar into the position of the affected tooth was planned. A surgical 3-dimensional guiding template and a tooth-shaped osteotome were manufactured to prepare the neo-alveolus (referring to the creation or modification of an alveolus to house the tooth) modification. Although the donor tooth was placed in the recipient socket with the buccal side of the root fully exposed, the transplant outcome was successful. PRACTICAL IMPLICATIONS The use of 3-dimensionally designed surgical osteotome could improve accuracy and surgical handling of a donor tooth autotransplant, even with substantial bone defects in the recipient site.

Abstract
One of the most challenging problems for orthodontists is that of multiple missing maxillary teeth in a growing patient. In many patients, a good treatment option is autotransplantation. This case report describes the multidisciplinary treatment of an 11-year-old girl with regional odontodysplasia affecting the maxillary right and left central incisors, and congenitally missing maxillary left lateral incisor and canine. Autotransplantation of the mandibular second premolars to the affected area was combined with orthodontic space closure, and the transplanted premolars were reshaped and restored with a resin composite to be in line with the left central and lateral incisors. After completion of the orthodontic treatment, gingivectomy was performed to obtain an even gingival contour and symmetrical gingival tissue. Space closure of the maxillary anterior teeth was achieved. Autotransplantation enabled the patient to retain her natural teeth rather than having a prosthesis or dental implant. The autotransplanted tooth allows for alveolar bone growth in synchrony with neighboring teeth and the formation of normal interdental papilla while adapting to functional stimuli and confers a high survival rate in the long term.

Abstract
A solitary median maxillary incisor can occur as a rare single dental anomaly or a symptom of the early-intrauterine developmental brain disorder of holoprosencephaly. The few published case reports about orthodontic treatment for this disorder have only described space opening for prosthodontic replacement of a central incisor. In contrast, the present patient was treated with extraction of the solitary median maxillary central incisor and orthodontic space closure with subsequent minimally invasive restorations in order to avoid looming esthetic or periodontal sequelae associated with any type of fixed bridgework or implant-borne crowns in the sensitive maxillary anterior area-which is especially indicated in young girls with a hyperdivergent growth pattern.

Abstract
INTRODUCTION The aim of this retrospective study was to assess the success, survival rate, and soft tissue esthetic of autotransplanted teeth. METHODS This study included patients with at least 1 tooth autotransplanted to the maxilla during childhood or adolescence. The autotransplantation technique included the removal of an immature tooth from a donor site and its placement in the maxilla as a replacement for a missing or extremely compromised tooth. The cases were properly restored to ensure function and esthetic. To be considered successful, the tooth should be asymptomatic at the time of assessment, no pain to palpation and percussion, have no signs of apical periodontitis or a sinus tract, have a periodontal probe ≤3, and have an absence of root resorption and development of at least 70% of the normal root. The esthetic evaluation of the soft tissue was based on the pink esthetic score and graded as very unsatisfactory, unsatisfactory, poor, fair, good, or excellent. Data were statistically analyzed at a significance level of 5%. RESULTS Thirty-five patients (23 males and 12 females) had 43 anterior teeth replaced, including 42 central incisors and 1 lateral incisor. The follow-up period ranged from 1-25 years. In regard to success and the survival rate, 43 teeth were assessed; 34 cases (79.07%) were considered successful and 9 (20.93%) unsuccessful. Only 1 tooth was lost, and 42 teeth remained functional (survival rate = 97.67%). In regard to the esthetic, 40 teeth could be assessed and were considered as excellent (30%), good (35%), fair (27.5%), and poor (7.5%); there were no reports of unsatisfactory or very unsatisfactory cases. CONCLUSIONS Tooth autotransplantation can be considered a valid procedure to replace lost teeth in the maxilla, presenting high survival and success rates. The overall esthetic of the patients was considered as satisfactory.

Abstract
Treatment following avulsion of a tooth in the growing patient requires a complex multidisciplinary therapeutic approach for the clinical team. The literature offers different therapeutic solutions following the avulsion of one or more teeth, but unfortunately all of them have negative repercussions on the patients' life quality, they involve long treatment plans, they are not always feasible, and they have limits. Alternatively, a new treatment concept that uses mini-implants can be considered and is presented with its rationale, clinical steps and 13 years of follow up of one case.

Abstract
PURPOSE Autotransplantation of teeth is an alternative treatment method in growing patients with hypodontia or impacted teeth. The purpose of the present study was to investigate the occurrence of, and predictors for, the loss of transplanted teeth in children and young adults. PATIENTS AND METHODS All patients who had undergone tooth transplantation at the Department of Oral and Maxillofacial Surgery, Turku University Hospital, from October 1, 2009 to January 5, 2017, were identified from the hospital's database. The outcome variable was survival of the transplanted tooth. The predictor variables were the transplantation type, donor tooth, maturity of the donor tooth, number of roots of the donor tooth, recipient's jaw, the need for extraoral storage of the donor tooth during surgery, continuation of root development during follow-up, and institution experience. One tooth was randomly selected from each subject. The Kaplan-Meier method for survival analysis, and the Cox proportional hazards regression analysis results were used to assess the association between survival and the risk factors. RESULTS The sample included 36 subjects with a mean age of 14.3 years; 33.3% were male, 45 teeth were transplanted, and the median follow-up time was 1.3 years. The 1-year survival rate was 87% (95% confidence interval [CI], 75 to 99%). A significant predictor for tooth survival was the continuation of root development (hazard ratio, 21.3; 95% CI, 2.1 to 215.0; P = .009). Although not statistically significantly, more favorable prognoses were found for distant than for transalveolar transplantations, 1-rooted than multirooted teeth, premolars than molars, teeth not stored in an extraoral media, and teeth that had been transplanted later during the study period. CONCLUSIONS The experience of the professional team, use of open apex premolars, and postoperative continuation of root development of the transplant were the factors associated with favorable outcomes. Transplants could benefit from the use of 3-dimensional models during surgery.

Autotransplantation of a Premolar with Incipient Root Development, an 18-Year Follow-Up. Eur Endod J 2017; 2:1-5. [PMID: 33403338 PMCID: PMC7757955 DOI: 10.14744/eej.2017.170080] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2017] [Revised: 03/10/2017] [Indexed: 11/30/2022] Open
Abstract
In young patients, premature tooth loss in the anterior maxilla after trauma is challenging for the patient and the dental professional, with serious implications from aesthetic and functional points of view, as well as from a craniofacial growth aspect perspective. Premolars autotransplanted into the maxillary anterior region have been shown to be a biological alternative in this situation. This report describes the clinical management of a case of premature loss of a maxillary central incisor after traumatic injury. A mandibular premolar at the stage of initial root development was transplanted into the alveolar socket of the lost incisor. After 18 years, the transplanted tooth remained responsive to pulp sensibility tests and the periradicular bone and soft tissues were within normal limits. Autotransplantation of premolar teeth into the maxilla could be considered an excellent treatment choice with many biological advantages over implants or fixed dentures as long as proper case selection is followed.

[PMID: 27633512 PMCID: PMC5025610 DOI: 10.1186/s13256-016-1041-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2016] [Accepted: 08/25/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Tooth replantation after traumatic avulsion or transplantation is a challenge in oral surgery. A special method named auto-alloplastic replantation, in which a titanium post is used after extraoral endodontic treatment, combines several advantages. The treatment is performed in one step with no further endodontic intervention, no wide root canal instrumentation, no recontamination, and reduced endodontic infection. This is the first report on replantation of an ectopic tooth in a patient with a cleft lip and alveolus using this method. CASE PRESENTATION This case report presents the treatment of a 13-year-old white boy with a cleft lip and alveolus who had an ectopic incisor in the cleft region. His rehabilitation was performed by a tooth transposition using the auto-alloplastic replantation technique. After preparation of the displaced incisor from the vestibule, extraoral endodontic treatment followed using a titanium post prior to replantation in a newly formed socket. In the follow-up, the tooth is still in place and functioning after 2 years. CONCLUSIONS This method can be used to bridge the years while a patient is young and jaw growth is incomplete until bone augmentation and implantation can be performed. The tooth will preserve the remaining alveolar ridge and help the adolescent psychologically.
