Rehabilitation of a Unilateral Cleft Palate with Endosseous Implants in an Edentulous Elderly Patient.

The objective was to describe the use of a maxillary obturator supported by dental implants and ball abutments in an adult edentulous unilateral cleft patient. Adult edentulous cleft patients who have had no corrective surgeries or failed attempts at cleft repair in childhood suffer from oronasal communication resulting in hypernasal speech, dysphagia, and compromised masticatory ability. Tissue-supported obturator prostheses in such patients provide for compromised function due to instability and lack of retention.

Effect of Long-term Immersion in Water and Artificial Saliva on the Flexural Strength of Two Heat Cure Denture Base Resins.

Aim: The aim of the present study was to compare and evaluate the flexural strength of heat-polymerized Lucitone 199 and SR Ivocap denture base resin materials which uses polymerization techniques of compression molding and injection molding respectively and effect of artificial saliva and distilled water on long-term.

Materials And Methods: Ninety specimens each from both the materials measuring 65 × 10 × 3 mm were prepared. After the polymerization, flexural strength was calculated after 24 hours (control group) without immersing in the liquid medium.
