Abstract
Prosthodontic decision-making process is done through analysis of clinical information and mutual communication between patient and dentist. When opposing teeth are extruded due to missing tooth or tooth defects, selection of appropriate treatment plan and predictory prognosis can be complicated in functional rehabilitation. In case of severely disharmonious occlusal plane result from extruded teeth, re-establishment of the occlusal plane is required, if necessary via prudent evaluation. In this case, class III patient had unesthetic appearance and mastication discomfort caused by disharmonious occlusal plane due to severe extrusion. Through a structured diagnostic process, appropriate treatment plan was selected. Esthetic and functional results were obtained through from full mouth rehabilitation with re-establishment of the occlusal plane. (J Korean Acad Prosthodont 2016;54:451-7)
