Method and system for providing feedback data useful in prosthodontic procedures associated with the intra oral cavity
First Claim
1. A system for providing feedback useful in at least one prosthodontic procedure associated with an intraoral cavity, the system comprising:
- one or more processors; and
memory, including instructions for execution by the one or more processors to cause the system to at least;
(a) obtain data relating to a first procedure comprising mounting of a dental prosthesis to a dental preparation in the intraoral cavity, wherein the data comprises information regarding a geometry of at least a portion of the dental preparation,(b) determine, based on the data and the first procedure, that a finish line of the dental preparation is not continuously defined about a periphery of the dental preparation, and(c) output feedback comprising finish line data, based on the determination of the not continuously defined finish line in step (b), comprising one or more areas of the finish line of the dental preparation about the periphery of the dental preparation missing from the data, by superimposing the finish line data on the data.

Abstract
Feedback data useful in prosthodontic procedures associated with the intra oral cavity is provided. First, a 3D numerical model of the target zone in the intra oral cavity is provided, and this is manipulated so as to extract particular data that may be useful in a particular procedure, for example data relating to the finish line or to the shape and size of a preparation. The relationship between this data and the procedure is then determined, for example the clearance between the preparation and the intended crown. Feedback data, indicative of this relationship, is then generated, for example whether the preparation geometry is adequate for the particular type of prosthesis.

18. One or more non-transitory computer-readable storage media having stored thereon instructions that, when executed by one or more processors of a computer system, cause the computer system to at least:
-
(a) obtain data relating to a first procedure comprising mounting of a dental prosthesis to a dental preparation in the intraoral cavity, wherein the data comprises information regarding a geometry of at least a portion of the dental preparation, (b) determine, based on the data and the first procedure, that a finish line of the dental preparation is not continuously defined about a periphery of the dental preparation, and (c) output feedback comprising finish line data, based on the determination of the not continuous defined finish line in step (b), comprising one or more areas of the finish line of the dental preparation about the periphery of the dental preparation missing from the data, by superimposing the finish line data on the data. - View Dependent Claims (19, 20, 21)
