ABSTRACT:
Background: Orthognathic surgery is one of the most used approaches for treating dentofacial deformities. Patients seeking orthognathic surgery are mainly motivated by esthetical concerns as well as by issues related to temporomandibular joint (TMJ) dysfunctions. Surgery consists of osteotomies of both the maxillary bone (LeFort I) and the mandible (BSSO) followed by fixation. Different types of devices include bicortical screws, miniplates with monocortical screws and natural fit plates. One of the primary risks of this type of surgery is the condylar sag, which is an immediate or late change in position of the condyle in the glenoid fossa and may lead to a modification of the preplanned occlusion.
Methods: A preliminary study was conducted to compare the biomechanical stability of three different types of mandibular fixation. The analyzed devices included bicortical screws, miniplates and TEKKA natural fit plates, placed after a bilateral sagittal split osteotomy (BSSO) of the mandible in patients with malocclusion class II and III.
Conclusions: In this preliminary study the onset of condylar sag, as well as future TMJ dysfunctions, seem to be reduced using TEKKA Natural Fit Plates for osteosynthesis. Further investigations will be performed increasing the sample size in the future, to verify the conclusions of this study.
