This paper describes an adhesive technique to restore cervical erosion and abrasion lesions so that the area can be used for clasp retention of a removable partial denture. An enamel fragment is used to recontour the area, achieving function and esthetics.
The purpose of this research was to test the traction resistance of cast posts and cores with and without roughness cemented with zinc phosphate cement in cuspids roots, with smooth and roughness canals walls. From the results of the tests and statistical analysis there was significant difference between roughness posts cemented in root canals with roughness walls and smooth posts cemented in smooth root canals. It was also analyzed, the retention of cast crows cemented on roughness posts and canals and it was concluded that posts are responsible for crows retention, when the cores were done at the correct way.
Three techniques of centric relation registration were compared using the "Jig" (LUCIA), the "Leaf-Gauge" (LONG JUNIOR) and an wax anterior guide. The casts were mounted and analysed in a Whip-Mix articulador. The results permitted to conclude that, from the statistical viewpoint, did not occurred significant differences among techniques and centric relation occurred in an area not in a point. Because of facility and quickness the technique advocated by LON JUNIOR is recommended.
