      INFERENCE OF THE FACIAL NERVE IN DENTAL OCCLUSION (Abstract): Facial nerve distributes its branches to an unitary structure called superficial musculoaponeurotic system (SMAS). It consists IN a conjunctive and muscular network which gives mechanical support for perioral muscles by forming of tension zones. Our aim is to demonstrate the anatomical and physiological connection between mimic muscles, supplied by facial nerve and masticatory muscles with perioral topography, supplied by trigeminal nerve. We compared the results of dissection of anatomical piece with intraoperatory and imagistic studies to understand the the role of support provided by SMAS in dental occlusion and mastication. Both dermal and periostal insertions of perioral SMAS allow lip symmetrical mobilizing and occlusion. We traced the force vectors of the supporting SMAS insertions which proved they act as levers for masticatory muscles activity.
Key words: FACIAL NERVE, MASTICATION, DENTAL OCCLUSION, SMAS
