Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
134 words
A drill guide comprising: a reference block from which protrudes a location pin adapted to fit in a hole in a mouth of a patient; and at least one guide block comprising an extension arm which slides in and out of an aperture formed in said reference block, said extension arm defining a generally straight longitudinal axis extending from said at least one guide block to said reference block, said extension arm being selectively fixable with respect to said reference block at a point on said longitudinal axis by means of a fastener which fastens said extension arm to said reference block. wherein said guide block is formed with a through hole for guiding therethrough a drill bit; and wherein said guide block and said extension arm are rotatable generally about said longitudinal axis.
Claim 2
Dependent Claim
134 words
A drill guide comprising: a reference block from which protrudes a location pin adapted to fit in a hole in a mouth of a patient; and at least one guide block comprising an extension arm which slides in and out of an aperture formed in said reference block, said extension arm defining a generally straight longitudinal axis extending from said at least one guide block to said reference block, said extension arm being selectively fixable with respect to said reference block at a point on said longitudinal axis by means of a fastener which fastens said extension arm to said reference block. wherein said guide block is formed with a through hole for guiding therethrough a drill bit; and wherein said guide block and said extension arm are rotatable generally about said longitudinal axis.
