Dental dilacerations are abrupt deviations of the longitudinal axis of the crown or root portion of the tooth, caused by traumatic axial displacement of previously formed hard tissue in relation to the developing soft tissue.
Case presentation: A 13-year-old boy in good general health was referred for root canal treatment of the maxillary left central incisor, for which abnormal crown morphology impeded orthodontic treatment. He presented bilateral crown dilaceration at both maxillary central incisors. Treatment involved a CAD/CAM milled veneer of the maxillary left central incisor and semidirect warm composite veneer of the maxillary right central incisor. Follow-up and monitoring of the restoration was performed through .stl file analysis.
Discussion: Crown dilaceration severity assessment is crucial for deciding the best treatment plan for each case. In this patient, additive restorative protocols, CBCT, and 3D digital model analysis were the most useful aids by providing key multidisciplinary information.
Conclusion: A multidisciplinary treatment workflow with a minimally invasive approach aided by digital tools such as CBCT and CAD/CAM technologies is useful to achieve successful and predictable outcomes in crown dilaceration cases.
