Malocclusion Clinical Trial
Official title:
Jawline Improvement Using Patient-specific Angle Implants With Virtual Planning in Orthognathic Surgery
Background: Jawline improvement is nowadays a strong patients' demand. Among patients undergoing orthognathic surgery, it remains sometimes a challenge to manage angle definition due to the classic mandibular osteotomy trait which mostly allows sagittal mandibular movements but can't modify the ramus height. A few types of osteotomies can be used to improve jawline's shape while correcting malocclusion, but they remain technically difficult and often imply the necessity for bone grafting and/or the use of a specific saw and screwdriver. The advent of computer-assisted surgical planning and computer-aided design/ computer-aided manufacturing (CAD-CAM) techniques for patient-specific implant (PSI) fabrication has enabled new methods for managing the jawline in orthognathic surgery. The aim of this study was to assess jawline improvement with patient-specific angle implants in patients undergoing orthognathic surgery with standard osteotomies.Methods: A virtual simulation of a Le Fort I osteotomy (if needed), a sagittal split ramus osteotomy with patient-specific titanium angle implants, and a genioplasty (if needed) was conducted on a preoperative three-dimensional (3D) model of each patient's skull using ProPlan CMF software (Materialise, Leuven, Belgium). Computer-assisted osteotomy saw-and-drill guides and patient-specific implants (PSIs, titanium plates and angle implants) were produced and used during the surgery. The investigators chose to focus on jawline improvement by comparing the preoperative and the post-operative 3D-photographs using the VECTRA H2 3D imagine system (Canfield Scientific, **).
