Ridge Mapping
A clinical technique using a calibrated probe or caliper to measure the buccolingual width and height of the alveolar ridge through the overlying soft tissue prior to implant planning.
Full Definition
Ridge mapping involves inserting a calibrated probe at multiple points along the residual alveolar ridge under local anaesthesia to measure bone dimensions through the mucosal tissue. The resulting measurements help the clinician determine whether sufficient bone volume exists for implant placement without radiographic cross-sectional imaging alone. It is commonly used as a low-cost adjunct to two-dimensional radiography. Editors should note the term is always two words and is not synonymous with ridge augmentation, which is a surgical corrective procedure. Documentation of ridge mapping findings typically appears in pre-surgical assessment notes.
Usage
Usage note: Do not hyphenate as 'ridge-mapping' when used as a noun; hyphenation is acceptable only when used as a compound modifier before a noun (e.g., 'ridge-mapping technique').
In Context
- "Ridge mapping confirmed a buccolingual width of 4.2 mm, indicating the need for lateral bone augmentation prior to implant placement." — Pre-surgical clinical notes
