<p>This invention is a dental prosthesis for replacing a tooth or teeth in a patient's mouth either adjacent to existing teeth or between a first tooth anterior and a second tooth posterior of the edentulous space. The dental prosthesis includes a multi-section infrastructure (10) with a main supporting bar (11), a secondary support section (15) comprised of buccal buttress (16), and lingual buttress (17) received in grooves (18, 19), respectively. The secondary support acts to prevent or limit rotation of the pontic around the longitudinal axis of the main support bar (11). Additionally, a method for replacing a tooth or teeth in an edentulous space either adjacent to existing teeth or between a first tooth anterior of the second tooth posterior of the edentulous space, and a method for forming an improved dental prosthesis for such edentulous space in situ in the patient's mouth.</p> |
