A custom-made porcelain-fused-to-metal ring pontic for a removable partial denture may be color characterized and glazed by use of familiar procedures. The use of this type of pontic on removable partial dentures has the potential of superior esthetic results when replacing isolated maxillary anterior teeth.
Restoration of the mandibular compromised ridge requires various treatment modalities. The simplest approach often is to extend the denture base adequately for proper use of all available supporting tissues. If the patient is incapable of wearing a conventional denture, the surgical approach becomes necessary. Surgical avenues include vestibular extension procedures that increase vestibular depth and augmentation procedures, which include (1) overlay grafts of rib or the crest of the ilium, (2) osteotomy grafts to include the visor osteotomy and the interpositional bone graft, (3) alloplastic grafts of which hydroxyapatite augmentation is the most common, and (4) various types of implants to restore the compromised ridge. The ultimate goal, regardless of the treatment modality chosen, is to restore the patient to a level of masticatory function.
A patient with divergent roots as abutments was treated with a bar-clip overdenture. The treatment allowed complete seating of the abutment copings despite the divergence of the roots because the attachment-receptacle portions slide together during cementation.
Proper use of a pantograph to program fully adjustable articulators is dependent on stable clutch construction. The technique described uses modeling plastic molded to the labial surfaces of acrylic resin clutches. The labial extensions of the modeling plastic resist lateral movement of the clutches, thereby enhancing clutch retention and stability.
