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.
