Which of the following implant materials density equals that of the alveolar bone
1) Chromium-cobalt
2) Titanium alloy
3) Stainless steel alloy
4) Bioglass
Prosthodontics
Answer: 2
Titanium alloys are commonly used in dental implants due to their favorable properties, including biocompatibility and mechanical strength. The density of titanium alloys is relatively close to that of human alveolar bone, which helps in achieving a good integration (osseointegration) between the implant and the bone. Other materials listed, such as chromium-cobalt and stainless steel alloys, have different densities and are not as compatible with bone in terms of density and biological response. Bioglass, while biocompatible, is not typically used as a structural implant material in the same way as titanium.
First step in altering the abutment contour for clasp retention in RPD is
1) Placement of guiding planes after disking the proximal surfaces
2) Placement of occlusal rests after reducing the occlusal surface
3) Planning for placement of clasps after reducing the proximal surfaces
4) The abutment tooth is not contoured unless it is short
Prosthodontics
Answer: 1
Before altering the abutment contour for clasp retention, it is essential to establish the guiding planes. This is done by disking the proximal surfaces of the abutment teeth to create a flat, smooth surface that will guide the RPD during insertion and removal. Once the guiding planes are in place, the contour of the abutment can be altered to accommodate the placement of the retentive elements such as rests and minor connectors.
