Abstract
The purpose of this study was to propose and validate an index evaluating 2D and 3D radiographic variables of autotransplanted maxillary canines. Setting and sample population are from the Department of Oral and Maxillofacial Surgery at University Hospitals Leuven. Eight oral‐maxillofacial surgeons rated 12 autotransplanted maxillary canines and adjacent bone using 11 rating variables. A new autotransplanted maxillary canine radiological index (AMCRI) was proposed. It consisted of 11 variables. These variables were based on 2D (intraoral) and 3D Cone Beam Computed Tomography (CBCT) radiographs. Intraclass correlation coefficient (ICC) and Fleiss's kappa statistics were performed to analyze intrarater and interrater agreement. Considering cumulative assessment of the AMCRI, the mean ICC value for the interrater agreement of the eight examiners was 0.94, representing an excellent agreement. Intrarater agreement was 0.91. The AMCRI is an objective tool in rating radiological outcome of autotransplanted canines and adjacent bone, when compared with the contralateral canine.
Highlights
Contraindicated (Andersson et al, 2012; Czochrowska, Stenvik, Bjercke, & Zachrisson, 2002; Schwartz‐Arad, Levin, & Ashkenazi, Maxillary canine impaction has been reported to occur in 2–3% of the 2004)
An autotransplanted tooth can be present in the jaw bone of autotransplanted maxillary canines in the long‐term follow‐up
It was developed considering the lack of a standardized method of evaluating and measuring radiographical outcome after autotransplantation of impacted maxillary canines
Summary
Contraindicated (Andersson et al, 2012; Czochrowska, Stenvik, Bjercke, & Zachrisson, 2002; Schwartz‐Arad, Levin, & Ashkenazi, Maxillary canine impaction has been reported to occur in 2–3% of the 2004). Autotransplantation is a potential are recommended for replantation in cases of dental trauma treatment option in cases in which surgical exposure and orthodontic (Andersson et al, 2012). 2008; Grisar et al, 2018) This treatment could be preferred consider- maxillary canine is the radiographic control with intraoral and 3D ing an unfavorable displacement, as well as failure of orthodontic CBCT images. There are other reasons This index can be helpful for the general dentist, orthodontist, and supporting this treatment, even if life‐long survival cannot be maxillofacial surgeon. It can be used in the screening for important achieved. Transplanted teeth have the capacity to preserve the alveo- variables determining outcome and the assessment of the final lar ridge, especially during growth, during which dental implants are result
