Osteotomy
Pronunciation: os-tee-OT-oh-mee
The surgical preparation of a precise channel or cavity in bone into which the implant fixture is inserted.
Full Definition
In implant dentistry, an osteotomy is the drilled preparation site created in the alveolar bone using a sequential set of drills (osteotomy drills or burs) of incrementally increasing diameter. The term is borrowed from general orthopedic surgery, where it denotes a bone-cutting procedure, but in the implant context it refers specifically to site preparation rather than bone division. Editors should note that 'osteotomy' in this specialty context does not imply bone removal or realignment. Correct use is critical in operative reports and consent documents.
Usage
Usage note: In implant dentistry reports, 'osteotomy' refers to the prepared drill site, not a bone-cutting corrective procedure. Clarify context to avoid ambiguity when documents cross surgical specialties.
