MODULAR REFERENCE SYSTEM TO DETERMINE SPACE REFERENCES ON A DENTAL GUIDE DEVICE TO GUIDE A DENTAL IMPLANTOLOGY PROCEDURE

摘要

A modular reference system for determining, on a diagnostic dental guide (24), space references to guide a dental implant procedure comprises: e) a first component (1), which is made from radio- transparent material and can be fixed in a preferred point (27) of the dental guide (24); f) a plurality of second components (2, 3) divided into reference components (2) made from radio-opaque material, all having the same dimensions, and spacer components (3) made from radio-transparent material, each second component (2, 3) comprising respective means of coupling (7-10) for the pack assembly of the second components (2, 3), alternating reference components (2) with spacer components (3); g) a portion (4) for coupling of the first component (1) comprising a surface for assembly of the pack of second components; h) a third component (13) comprising at least one first portion (14), which can be mounted on the coupling portion (4) with coupling means (15, 16) in place of the pack of second components (2, 3) and on which it is possible to mark the space references (22) that can be obtained from an analysis of a respective volumetric computerised tomography cross-section image of a maxillofacial complex including the dental guide (24) on which the pack of second components (2, 3) is fixed, and a second portion (17), which is perpendicular to and integral with the first portion (14); on the first (14) and second (17) portions of the third component (13) it being possible to mark two respective space references (22, 23) that can be obtained from an analysis of two respective volumetric computerised tomography cross-section images, at right angles to each other, of a maxillofacial complex including the dental guide, it being possible in these images to see the pack of second components (2, 3) according to respective views along two planes at right angles to each other.
