Surgical guide system for dental implantology and method for making the same

摘要

A surgical guide system for dental implantology has a plate (10) provided with a guide sleeve (2) delimiting a through hole with an axis oriented to a predetermined direction. A drill (4) for osteotomy has a spindle connected to a handpiece with drilling portion (41), the drill (4) being for association with the guide sleeve (2) during osteotomy. The diameter (d41) of the drilling head portion (41) is larger than the inner diameter (d2) of the guide sleeve (2) and the spindle is of smaller diameter, such that the association of the drill (4) to any of the guide sleeves (2) can be performed only by inserting the spindle through a gingival side of the sleeves. Upon association of the drill with the sleeve, the drilling head (41) protrudes from the gingival side (2G) thereof. The surgical guide has a void (100) accommodating the drilling head (41) of the drill.

主权项

1. A method for making a guide surgical system for dental implantology, the method comprising:
producing a plate provided with at least one guide sleeve delimiting a corresponding through hole of which an axis is oriented according to a predetermined direction, and producing a model of anatomical structures that underlie a dental arch or part of a dental arch by means of electronic processing of diagnostic images, in which said model exhibits holes oriented according to a given angle, in each of said holes being inserted a laboratory implant; wherein, the step of producing a plate comprises:
placing a spacer on each said laboratory implant, the spacer being provided with:
a shank inserted into a cavity of the laboratory implant,a cylindrical middle part having a lower base contacting an upper base of the laboratory implant, anda cylindrical upper part having a diameter less than a diameter of the cylindrical middle part and a threaded stem screwed in said cylindrical middle part, wherein a height of said cylindrical middle part is greater than a height of a drilling head of a drill for osteotomy;placing said at least one guide sleeve on the cylindrical upper part,placing self-curing resin around said at least one guide sleeve to form said plate with said at least one guide sleeve incorporated therein; andwhen curing of the self-curing resin is completed, unscrewing said upper cylindrical part from said cylindrical middle part and extracting said upper cylindrical part through said at least one guide sleeve.
