METHOD OF MAKING A SURGICAL TEMPLATE USED FOR A COMPUTER-GUIDED DENTAL IMPLANT SURGERY

摘要

A method of making a surgical template comprises: producing a 3-D geometrical image by a CT scanning performed on a patient's jaw and establishing corresponding implant planning data to obtain a 3-D first digital image, making a positive plaster model of the patient's jaw, scanning the plaster model to obtain a 3-D second digital image, overlapping the second digital image on the first digital image to obtain a computer representation of the plaster model and at least one implant to be mounted according to the implant planning data, drilling the plaster model to form at least one pinhole according to the implant planning data, inserting a pin into the pinhole, producing a negative template body from an assembly of the plaster model and the pin with a thermoplastic dental material so that the negative template body has at least one implant guide hole and constitutes the surgical template.
