Abstract

INTRODUCTION
To correct abnormal occlusal plane by orthognathic surgery, we need to have clear criteria for therapeutic occlusal plane. Authors introduced the concept of individualized ideal occlusal plane(Yplane), which is determined by the size and form of the mandible, and the ideal incisor tip considering upper and lower lip. Authors studied the following to verify if the actual occlusal plane of the patients with optimal jaw relationship corresponds with the individualized ideal occlusal plane. PATIENTS: We reviewed 44 patients who have normal occlusion visitied in the Dept. of orthodontics, Pundang CHA hospital.
METHODS
We evaluated if there are agreement between individualized ideal occlusal plane(Y plane) and occlusal plane of actual patients. And we confirmed if tested group has a normal face by measuring FABA, FMA, AB-LOP.
RESULTS
There were no significant differences of FABA, FMA, AB-LOP, Mo-Y plane between male and female. FABA, FMA and AB-LOP were included in the normal value. Average distance of Mo-Y plane was 0.75+/-0.78mm.
CONCLUSION
Individualized ideal occlusal plane may be applied to orthognathic surgery
