A direct structural and functional connection between ordered, living bone and the surface of a load-carrying implant 1.
Endosseous dental implant
A device inserted into the jaw bone (endosseous) to support a dental prosthesis. It is the ‘tooth root’ analogue and is often referred to as a ‘fixture’ 2.
The component which attaches to the dental implant and supports the prosthesis. A transmucosal abutment (TMA) is one which passes through the mucosa overlying the implant. A temporary or healing abutment may be used during the healing of the peri-implant soft tissue before the definitive abutment is chosen 2.
A screw used to connect an abutment to the implant 2.
Single stage implant surgery
Surgical placement of a dental implant which is left exposed to the oral cavity following insertion. This is the protocol used in non-submerged implant systems 2.
Two stage implant surgery
Initial surgical placement of a dental implant which is buried beneath the mucosa and then subsequently exposed with a second surgical procedure some months later. This is used in submerged implant systems 2.
