LLUSD (2015) - Chapter 3 - Biologic Basis for Bone Response to Implants There is never 100% bone contact at the implant-bone interface.*FalseTrueThe hardness of the bone immediately adjacent to implants is the same as that located farther away from the implant.*TrueFalseThe bone that forms during the stabilization phase is high density bone (woven bone) and it forms rapidly.*FalseTrueThe blood from an osteotomy site coats the implant and fills any spaces that may be present between the implant and bone.*FalseTrueThe response of bone to dental implants is the same as the response of bone to occlusal function as transmitted by the roots of teeth.*TrueFalseThe first phase in the development of the bone-implant interface has been termed the stabilization phase where subendosteal and subperiosteal calluses form and adhere to the implant.*FalseTrueIt has been proposed that the physiologic mechanism for maintaining osseous integration (osseointegration) is a sustained elevation in remodeling adjacent to the bone-implant interface.*FalseTrueWhen copious irrigation is used during implant placement surgery and slow revolution of the cutting instruments is used, there will be no bone necrosis.*FalseTrueThe blood that coats an implant undergoes coagulation and clot organization prior to formation of a pre-osseous matrix and bone.*FalseTrueThe second phase in the interface development is called the strength phase where strong weight bearing lamellar bone is formed.*FalseTrueIt takes about 12-16 weeks for the socket of an extracted tooth to fill with cancellous (woven bone).*FalseTrueBrånemark defined osseointegration as "a direct structural and functional connection between ordered, living bone and the surface of a load-carrying implant."*TrueFalseThe biologic activity of bone during growth and aging, and following surgical and prosthodontic procedures, is one of constant dynamic activity.*FalseTrue
