Abstract
A method of mapping a gingival surface of a patient's jaw using at least one spatially trackable reference object in a fixed spatial relation to that jaw and a spatially trackable mapping tool. A plurality of gingival surface coordinate sets are captured in a coordinate frame of the jaw. Each of the gingival surface coordinate sets is captured when the mapping tool is in contact with a corresponding gingival surface location on the gingival surface. A geometrical gingival surface descriptor is computed from the plurality of gingival surface coordinate sets.

A method of mapping a gingival surface of a patient's jaw using at least one spatially trackable reference object in a fixed spatial relation to that jaw and a spatially trackable mapping tool, the method comprising:
- capturing a plurality of gingival surface coordinate sets in a coordinate frame of the jaw, wherein each of the gingival surface coordinate sets is captured when the mapping tool is in contact with a corresponding gingival surface location on the gingival surface;
- and
- computing a geometrical gingival surface descriptor from the plurality of gingival surface coordinate sets.
A system for mapping a gingival surface of a patient's jaw using at least one spatially trackable reference object in a fixed spatial relation to that jaw and a spatially trackable mapping tool, the system comprising:
- at least one image sensor;
- and
- at least one processor;
- wherein the at least one image sensor is configured to capture a plurality of gingival surface coordinate sets in a coordinate frame of the jaw,
- wherein each of the gingival surface coordinate sets is captured when the mapping tool is in contact with a corresponding gingival surface location on the gingival surface;
- and
- the at least one processor is configured to compute a geometrical gingival surface descriptor from the plurality of gingival surface coordinate sets.
A non-transitory computer readable medium storing computer-executable instructions for configuring one or more processors to perform a method of mapping a gingival surface of a patient's jaw using at least one spatially trackable reference object in a fixed spatial relation to that jaw and a spatially trackable mapping tool, the method comprising:
- acquiring a plurality of gingival surface coordinate sets in a coordinate frame of the jaw, wherein each of the gingival surface coordinate sets is captured when the mapping tool is in contact with a corresponding gingival surface location on the gingival surface;
- and
- computing a geometrical gingival surface descriptor from the plurality of gingival surface coordinate sets.
