Implant Therapy in the Case of Unilateral Brodie’s Syndrome : a Case Report
Objectives: This case report aims to describe an approach consisting of a segmented Le Fort I osteotomy associated with implant placement on the right side to obtain a functional occlusion in the case of Unilateral Brodie's Syndrome when the orthodontic approach is unsuccessful.
Methods: A 40-year-old female patient presented with a right scissors bite and severe unilateral molar overbite. After the failure of an attempt to ingress the right molars and premolars by orthodontics, the patient was referred to our Department of Periodontology.
First, we proceeded to tooth extraction (14, 15, 16, 17, and 18 in the maxilla, and 45,46,47, and 48 in the mandible) with immediate placement of a removal partial denture with modified occlusal relationships.
6 months later, as the mandible was considered normal, a segmented Le Fort I osteotomy of the right maxilla was planned with combined implant placement in sites 14, 15, 16, and 17 with modification of the implant axis under local anesthetia. After 3 months, dental implants were placed in sites 45,46 and 47.
3 months later, the second stage surgery was accomplished, followed by an open tray technique impression after two months.
Lastly, definitive zirconia crowns were inserted with periodical clinical maintenance.
Results: The unilateral scissor bite was successfully treated by dental implants associated with orthognathic surgery.This allowed for a correction of the skeletal discrepancy and for the achievement of functional occlusal relationships on the right side.
Conclusions: In cases where orthodontic treatment fails, dental implants and orthognatic surgery can be used to successfully treat unilateral Brodie's Syndrome.
In the case of severe malocclusions, a meticulous clinical and radiological study must be carried out before proceeding with such a challenging treatment plan, and the practitioner's experience is essential.
