Method for calculating the final position of a dental implant to be implanted in a patient's mouth in a hole made with the aid of a surgical template

Method for predicting the actual final positioning of a dental implant to be implanted in a patient's mouth in a hole made in a portion of the patient's cranium with the aid of a surgical template (10), the method comprising the steps of:

• a) providing a surgical template (10) having a bushing (12) positioned and orientated so as to define the axis of the aforesaid hole, said bushing (12) being adapted to receive drill guide sleeves with which drills of progressively increasing diameter are to be guided for the making of the aforesaid hole;
• b) performing a CT scan of said portion of the patient's cranium with the surgical template (10) positioned thereon;
• c) removing the surgical template (10) from the patient's mouth;
• d) performing a CT scan on the surgical template (10) only;
• and
• e) generating, from the CT scans obtained in steps b) and d), a three-dimensional digital model of said portion of the patient's cranium, in which the surgical template (10), and therefore the axis of the aforesaid hole, are placed in the same position as that in which they were placed in step b).
