Abstract:

Introduction: A fixed version of removable double plate have been recently introduced, it is the Fixed Lingual Mandibular Growth Modificator (FLMGM). Aim: This case series study aimed at evaluating short-term morphological and positional changes of TMJ osseous structures as a result of 8. 3 months treatment using FLMGM. Materials and Methods: The study sample included 11 patients at pubertal growth spurt period with overjet more than 4mm, and skeletal Class II relationship associated with retruded mandible. Cone beam computed tomography, taken before and immediately after treatment, was used to three dimensionally evaluate the effects of treatment on the morphological and positional relationships of osseous structures of 19 TMJs. Results: Visual inspection of two dimensional slices failed to prove significant morphological changes in 58% of condyles in all three dimensional planes. Metric measurements showed, generally, minimal but significant changes including increased condylar width, articular fossa width and condylar area by 0. 35mm, 0. 46mm, 5. 74mm2 respectively, while inclination of articular eminence was decreased by 4?. At the baseline, the anterior position of the condyle onto the articular fossa was physiological, and as a result of treatment, limited total displacements anteriorly and inferiorly relative to Frankfort plane, were noted in the condyle (1. 2mm), fossa (0. 7mm) and articular eminence (1mm), with preserving the original position of the condyle onto the fossa. Conclusions: FLMGM treatment resulted in limited morphological and positional changes of TMJ?s osseous structures. Adaptation ability represented by adaptive condylar growth and temporal remodelling might be essential to compensate the anterior displacement of the mandible.
