TWO-STAGE PRECISION GUIDE AND METHOD FOR FIXING TO A LOW-HEIGHT MAXILLARY BONE A TRIPOD WITH SHORT DENTAL IMPLANT FUNCTION

摘要

The invention relates to a two-stage precision guide (45) and a method for fixing to a low-height maxillary bone a tripod with short dental implant function, said guide allowing an osteointegrated tripod to be positioned on a low-height maxillary bone in two simple steps. The guide (45) is formed by two elements, which are a fixation guide (1) and a drilling guide (25). In the first stage of use, using the fixation guide (1) adhered to the body (2A) of the tripod, the two-stage guide (45) allows the body (2A) of the tripod, which is characterised in that it contains five perforations, to be positioned on the bone. In the second stage of use, and once the body (2A) of the tripod has been fixed to the bone, the two-stage guide (45) allows the bone to be worked on safely using the drilling guide (25), by coupling the drilling guide to the two elements described above, that is to say, the fixation guide (1) and the body (2A) of the tripod. Once the holes have been made, the two parts of the two-stage guide (45) are removed to be subsequently fixed to the bone by means of the body (2A) of the tripod claimed, which has three identical feet. With the feet in place in the bone, a dental prosthesis can immediately be situated on the tripod when required, the tripod thus acting as a short dental implant
