Multidisciplinary approach of complicated crown fractures of both superior central incisors: a case report

Abstract –  Anterior crown fractures are a common form of traumatic dental injuries that mainly affect the maxillary central incisors, in children and teenagers. Since the development of the adhesive dentistry, many case reports of crown fractures restored using adhesive reattachment techniques were published. Complex cases, in which more than one tooth are involved, with fractures differing from each other, require specific treatment of each fracture, taking different advantages of the different remaining tooth structures. This case report describes a patient with dissimilar crown fractures of both superior central incisors. After the endodontic treatment, the patient was treated using the combination of several techniques: periodontal surgery (crown lengthening with apically repositioned flap and osseous resective surgery), adhesive technique and cast restoration plus esthetic crown. The periodontal procedure re-created the biologic width and proved to be a reliable adjunctive procedure to the adhesive and the prosthetic techniques used.
