An evaluation of wear of human enamel opposed by ceramics of different surface finishes.

Statement Of Problem: Surface of porcelain restoration is a matter of clinical concern because of its abrasive action on the opposing enamel.

Purpose: This study comparatively evaluated wear of enamel when opposed by three different surface finishes of ceramic.

Materials And Methods: A total of 60 metal-ceramic discs (10 mm × 2 mm) with different surface finishes were fabricated.

Prosthodontic management of a completely edentulous patient with microstomia: a case report.

Patients with microstomia who need to wear removable dental prosthesis often face difficulty of being unable to insert or remove the prosthesis because of restricted opening of the oral cavity. Prosthetic rehabilitation of patients with microstomia presents difficulties in all the clinical steps. In such patients, it is difficult to make impressions and fabricate dentures using conventional method.

Waxing techniques to develop proper occlusal morphology in different occlusal schemes.

Static and dynamic occlusal interferences frequently need to be corrected by selective grinding of the occlusal surface of conventional cast, porcelain fused to metal and all-ceramic restorations. Proper dimensional contours and occlusal morphologies of these restorations is an important consideration in overall success of the case. Various types of occlusal morphologies and contact relationships of posterior reconstructions are dependent on the occlusal schemes (Cusp-fossa or Cusp-marginal ridge) and the requirements of the patient's masticatory system.
