Gum tissue guide, systems and methods of producing and utilizing the same
A method, device and system for modifying the gingival margin of a patient is disclosed. A method includes obtaining an electronic model of the dentition of a patient, determining an incision path along the gingival surface based on the electronic model, generating and fabricating a guide arrangement to assist in cutting the gingival surface of the patient, mounting the guide arrangement to the dentition of the patient, and cutting the gingival surface of the patient with the assistance of the guide arrangement. A guide arrangement includes a mounting portion and a template portion coupled to the mounting portion along the gingival surface of the guide arrangement and positioned to provide a desired incision path. A system includes a three dimensional scanner, a computer system and a fabricating device.
1. A gum tissue modification guide arrangement fabrication system comprising:
a three-dimensional scanner configured to obtain spatial data corresponding to dentition, including a gingival surface, of a patient;
a computing system coupled to the three-dimensional scanner, the computing system being programmed to generate an electronic model image representing the dentition of the patient based on the spatial data obtained by the scanner, generate an incision path along the gingival surface of the dentition based on a desired modification to a gingival contour of the dentition, and generate an electronic model image of a guide arrangement that defines a desired gingival contour of the dentition and includes a template portion defining a guide edge along the incision path; and
a fabricating device coupled to the computing system, the fabricating device configured to fabricate the guide arrangement based on the electronic model images of the guide arrangement, wherein the guide arrangement is configured to extend beyond the patient's gingival margin when worn by the patient.
2. The system of claim 1 , wherein the computing system is also configured to enable display, manipulation, storage, and transmission of the electronic models.
3. The system of claim 2 , wherein the computing system is also configured to enable a user to manipulate the electronic model of the teeth of the patient to plan a desired gingival contour of the teeth.
4. The system of claim 1 , wherein the three-dimensional scanner is a line-scanner.
5. The system of claim 1 , wherein the fabricating device is configured to print the guide arrangement in surgical grade polymer.
6. The system of claim 1 , wherein the spatial data corresponding to dentition of a patient is obtained from a dental cast, the dental cast representing the dentition of a patient.
7. The system of claim 1 , wherein the spatial data corresponding to dentition of a patient is obtained from an intra-oral scanner.
