Endosteal implants
Also known as: Endosseous implant, Root-form implant, Endosteal implant
Implants placed within the jaw bone itself — the classification that covers virtually all modern root-form dental implants.
Research in progress. Some fields on this entry are not yet verified against a primary source, so we have left them blank rather than filling them in — and this page is not published to search engines until they are.
Key facts
| Classification | Endosteal implants pierce only one cortical plate of the maxilla or mandible; the most frequently used endosteal implant is the root-form implantVerified spec[1] |
|---|---|
| How it differs | Distinguished from subperiosteal implants, in which a custom cast frame is placed directly beneath the periosteum, and from transosteal implants, which cross both cortical platesVerified spec[1] |
| Terminology | "Endosteal" and "endosseous" are used interchangeably. Because nearly every implant a patient will be offered today is endosteal, the term is more useful for reading older literature and device classifications than for choosing between treatments. |
| Typical use | The default category for replacing one tooth, several teeth or a full arch wherever there is, or can be created, sufficient bone volume to house the implant body. |
| Clinical evidence | Insufficient evidence(The category is too broad for a single survival figure; evidence is reported by system, site and indication rather than by classification) |
Overview
Endosteal simply means "within the bone", and it is the classification into which essentially every implant in routine use falls, including all the screw-shaped root-form implants patients are shown in a consultation. Its counterparts in the older classification are the subperiosteal implant, which rests on the bone under the periosteum, and the transosteal implant, which passes right through the jaw. The distinction matters mainly for reading the literature and device regulations: a paper from the 1980s comparing "implant types" may be comparing categories that no longer compete with one another. Because the group is so broad, it makes little sense to quote a survival rate for endosteal implants as a class — outcomes are reported by system, site and indication instead.
