Missing teeth should be replaced as soon as possible to maintain arch integrity and thereby avoid both morphologic and functional derangements in the occlusion. Otherwise, changes occur that upset the masticatory system, such as extrusion of the teeth opposing the edentulous areas along with their alveolar housing, their supporting tissues and ultimately the maxillary sinus. Concurrently with extrusion, shifting of the interproximal contacts and migration of the adjacent teeth occur, thereby impairing function and causing disharmony. Good oral health cannot be achieved when changes in tooth position alter the coronal contour and occlusion interfering with mutual support, which encourages food impaction and retention, further leading to osseous defects.
