Development and validation of the autotransplanted maxillary canine radiological index

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.

Long‐term outcome of autogenously transplanted maxillary canines

“…Radiographical outcome of the transplanted canine was assessed with the autotransplanted maxillary canine radiographical index (AMCRI) (Grisar, Vanpoecke, et al, ). Twelve of the transplanted maxillary canines were scored to have an excellent, 3 with a good, 7 with an acceptable and 4 to have a poor radiological outcome (Figure ,,).…”

“…Radiologic examination allowed evaluation of root resorption, periodontal ligament and lamina dura formation, ankylosis, alveolar bone loss, and apical inflammation. Radiographical outcome of the transplanted canine was assessed with the autotransplanted maxillary canine radiographical index (AMCRI) as described by Grisar et al (Grisar, Vanpoecke, et al, ).…”

“…All transplanted teeth that were still in place were eligible for recall and further evaluation. Each patient signed a written informed con- ( Grisar, Vanpoecke, et al, 2018).…”

“…The success rate was only calculated for the transplanted teeth that were evaluated on recall visits. In this study was 22 of the 27 surviving transplanted teeth on recall were evaluated as successful after clinical aesthetic and radiological evaluation (Grisar, Claeys, et al, 2018;Grisar, Vanpoecke, et al, 2018).…”

Current status of digital dental surgery

“…Since the speed of processing of mathematical calculations of new generation processing units has been greatly improved, analytical and CAD softwares for dental applications are nowadays able to detect in real-time any area of reduced bone density or to make the 3D plan for an ideal bone defect reconstruction. 17,18 We should bear in mind that these CAD planning processes have not yet been automated; these are still largely based on the human factor of reasoning, analysis and guidance. 19 The development of the system towards automation is directly connected with the development of artificial intelligence able to control and manage these services, and it has not been sufficiently developed to respond to a challenge like this.…”
