Abstract

Dental attrition is the mechanical wear caused by functional or para-functional dento-dental contact without food interposition or the action of other tooth extrinsic factors [1]. Microscopically, parallel striations are observed. Macroscopically glossy faces appear with well-rounded edges. Two male patients with accentuated attritions to the upper frontal teeth were examined. The primary difference between the two cases, which has led to a different therapeutic approach, is the presence in one of the patients of the diastema and inter-dental spaces of considerable size. As a result, in one patient the treatment consisted of a fixed partial denture that included the whole group of upper frontal incisors. A unitary fixed denture could not be achieved for the second patient because coronary morphology and height-to-width. It was decided to individually recover each tooth through corono radicular reconstruction using glass fiber posts, after the pulpectomy has been done. The first patient benefited from a fixed physiological partial denture that included the entire group of upper frontal incisors. For the second patient, individual metal crowns were made to achieve optimal morphofunctional appearance. Increased mechanical wear to the level of the upper incisors occurred as a result of the loss of chewing units in the lateral areas. In addition to the unaesthetic appearance, dental sensitivities have begun to appear in some of the frontal teeth, which require devitalization. The purpose of any prosthetic treatment is to achieve the restoration of dental morphology and implicitly of facial aesthetics, corroborated with the restoration of stomatognathic system functions.
