Q. Explain the Bone Implant Interface?
Three phases have been described in the development of bone implant interface.
1. Stabilization phase
Subendosteal and subperiosteal calluses form and adhere to implant surface. This bone is low in density (woven bone) and forms rapidly.
2. Strength phase
Once the implant is stabilized process of resorption by osteoclasts begins. Bone formed is stronger (lamellar bone) and is weight bearing.
3. Durability phase
Bone undergoes extensive remodeling and additional strength is developed. With remodeling and proper prosthodontic function the interface bone tends to show very mature osteonal and lamellated bone. Bone remodeling and changes occur continuously to long terms success and can conversely contribute to failure.
