Patent ID: 7909606

Claim:
Method for planning and performing dental treatments, comprising: acquiring a set of data representing a position, a shape and dimensions of at least one site inside the oral cavity of a patient who has to undergo a dental treatment and representing the shape of at least one portion of an outer surface of the face of said patient in a plurality of different facial expressions, wherein said step of acquiring comprises transduction of said acquired set of data into a set of digital data; subsequently storing said set of digital data inside a storing unit operatively associated with a computer; conducting a check-up of the condition of the patient and determining the type of necessary dental treatment, wherein said check-up is performed on a first virtual model suitable for visually reproducing said at least one site and the at least one portion of the outer surface of the patient's face; designing a prosthesis virtual prototype of a dental prosthesis that can be fitted at said at least one site during said treatment, and determining a second virtual model suitable for visually reproducing said at least one portion of the outer surface of the patient's face after said dental prosthesis is installed in the patient's oral cavity, using a software program implemented on said computer that starts from said set of digital data and processes said digital data to build said prosthesis virtual prototype and said second virtual model; preparing said at least one site using a dental instrument and said software program and using said prosthesis virtual prototype of the dental prosthesis and using said second virtual model, before said dental prosthesis is manufactured and installed; and using said software program to perform the following steps: processing, using said prosthesis virtual prototype of the dental prosthesis and using said second virtual model, a three-dimensional graphic representation of the relative position of said dental instrument with respect to the at least one site to be prepared, and controlling a quantity of material removed using said dental instrument from a tooth, from a pillar of an osteointegrated implant or from an area of bone tissue where an osteointegrated implant is to be installed; wherein said method further comprises: reading a virtual impression of said at least one site prepared for the fitting of said dental prosthesis, wherein said virtual impression is in the form of a three-dimensional image, said step of reading being performed at the same time as said step of preparing using said dental instrument; and manufacturing and installing said dental prosthesis.
