Abstract
An in-vivo dental surgical guide verification method including: receiving first information including: dental surgical guide information of a dental surgical guide, and hard structure information of a hard structure of a patient's mouth; positioning the surgical guide within the patient's mouth; contacting a stylus to a surface of the hard structure of the patient mouth; acquiring image information corresponding to an image which includes at least a portion of the stylus and a portion of the dental surgical guide therein using an imager; and comparing the image information with the first information.
Claims20
An in-vivo dental surgical guide verification method using a dental measuring device, said dental measuring device comprising a stylus and an imager connected to said stylus, the method comprising:
- a. receiving first information comprising:
- i. dental surgical guide information of a dental surgical guide;
- ii. subgingival bone information of a subgingival bone of a patient's mouth;
- and
- iii. a relation between parts of said dental surgical guide and said subgingival bone when said dental surgical guide is within said patient's mouth;
- b. calibrating said imager to said stylus in order to generate a known position of a tip of said stylus in relation to said imager;
- c. positioning said surgical guide within said patient's mouth;
- d. while said surgical guide within said patient's mouth, contacting said stylus with a surface of said subgingival bone of said patient's mouth;
- e. while performing said contacting, acquiring image information corresponding to an image which includes at least a portion of said stylus and a portion of said dental surgical guide therein using said imager;
- and
- f. comparing said image information with said first information, said comparing comprising:
- iv. estimating, using said image information, a first dimension between said dental surgical guide and said patient's mouth subgingival bone in relation to said known position of said tip of said stylus in relation to said imager when performing said contacting;
- and
- v. comparing said first dimension with said first information,
- g. detecting if a result of said comparing is a match between said first dimension and said first information thereby verifying that a topography of a preplanned drilling site matches a drilling plan as defined by said dental surgical guide and said expected topography matches the contacted surface of said subgingival bone.
An in-vivo dental surgical guide verification system comprising:
- a. a dental measurement device including a distal portion sized and shaped to be inserted into a human mouth, said distal portion comprising:
- i. a stylus;
- and
- ii. at least one imager configured to acquire at least one image when said stylus is in contact with a subgingival bone of a patient's mouth, said image including at least a portion of said stylus and at least a portion of a dental surgical guide positioned within a patient's mouth;
- b. circuitry configured to:
- iii. receive first information comprising:
- A. dental surgical guide information of said dental surgical guide;
- B. subgingival bone information of said subgingival bone;
- and
- C. a relation between parts of said dental surgical guide and said subgingival bone when said dental surgical guide is within said patient's mouth;
- iv. calibrating said imager to said stylus in order to generate a known position of a tip of said stylus in relation to said imager;
- v. while said dental surgical guide within said patient's mouth, receive said at least one image, when said stylus is in contact with said patient's mouth subgingival bone;
- and
- vi. compare said at least one image with said first information by:
- D. estimating, using said at least one image, a first dimension between said dental surgical guide and said patient's mouth subgingival bone in relation to said known position of said tip of said stylus in relation to said imager when performing said contacting;
- and
- E. comparing said first dimension with said first information;
- vii. detecting if a result of said comparing is a match between said first dimension and said first information thereby verifying that a topography of a preplanned drilling site matches a drilling plan as defined by said dental surgical guide and said expected topography matches the contacted surface of said subgingival bone.
