Abstract

In a method and apparatus for supporting dental implantation surgery, a three-dimensional CT image of jaws of an object is acquired. A reference site of the jaws and an implantation position of a gum in the jaws are set in the three-dimensional CT image. The implant is implanted at the implantation position. A three-dimensional optical image of an inside of an oral cavity of the object is then produced. The reference site is positionally set in the three-dimensional optical image through recognition of a shape of the reference site in the three-dimensional optical image. A surgical tool is positionally controlled to the implantation position in the oral cavity, based on i) a relationship between the position of the reference site and the implantation position of the gum in the three-dimensional CT image and ii) the position of the reference site in the three-dimensional optical image.

Description

technical field [0001] The present invention relates to a method and apparatus for supporting dental implant procedures. Background technique [0002] Dental implants are artificial tooth roots that are placed in the jaw to hold a crown or support a prosthetic appliance. The parameters of the dental implant, such as size, orientation, shape, etc., need to be determined on a patient-to-patient basis and according to the condition of the site where the dental implant is implanted. For example, the patent document JP-A-2009-501036 proposes a method of determining these parameters on a computer-based simulator. [0003] When implanting dental implants, precise positioning needs to be performed in the patient's mouth. For this purpose, patent document US2009 / 0253095A1 proposes a method in which a guide member is used to fix the position of the patient's head for implanting a dental implant at a predetermined position using a surgical device interlocked with the guide member. ...
