Abstract:
1. A GRS implant drilling guide for placing a pilot hole for a dental implant post comprising: a cylinder with a long axis comprising an open top first end, an open lower second end, an exterior circular circumference and a circular hollow interior, the circular hollow interior extending from the open top first end to the open lower second end wherein the external circular circumference adjacent to the second end has a circular circumferential ball-shaped enlargement; a housing with a long axis comprising an exterior and a hollow interior with a circular circumference, an open top first end and an open lower second end, the hollow interior extending from the open top first end to the open lower second end, a circular ball-shaped enlargement of the interior circumference adjacent to the lower second end shaped to receive the circumferential circular ball-shaped enlargement of the cylinder, the hollow interior progressively enlarges from the circular ball-shaped enlargement towards the top first end, the progressive enlargement at 20 degrees to the long axis of the housing wherein in use the second housing end is placed upon an edentulous dental ridge where it is secured, or held in place, with a putty and the circular circumferential ball-shaped enlargement of the cylinder fits within the circular ball-shaped enlargement of the housing and the first end of the cylinder fits within the top first end of the housing wherein the cylinder may be pivoted around the ball shaped enlargement end up to 20 degrees from the housing long axis; a threaded set screw housing containing a threaded channel with a set screw at a right angle to the housing long axis adjacent to the circumferential circular ball-shaped enlargement, the threaded channel opening into the housing interior wherein when the set screw is turned clockwise inwards until the set screw is seated against the circular circumferential ball-shaped enlargement of the housing, locking the cylinder in its axial position within the housing; a longitudinal positioning guide with a first and second end and an axial circumference comprised of a platform at the first end, a longitudinal stem extending from the platform to the second end and circumferential male keyways on the stem adjacent to the platform; a surgical circular ring with an interior and an exterior, the interior containing keyway grooves which engage the male keyways of the positioning guide when the stem of the positioning guide is placed within the interior of the surgical circular ring and turned clockwise wherein, with the surgical circular ring attached to the positioning guide, the second end of the positioning guide is placed in the first end of the cylinder and seated to the second end of the cylinder where the positioning guide is used to position the cylinder, when the cylinder is correctly positioned the set screw is turned clockwise which locks the cylinder in position, the surgical circular ring is then secured to the edentulous ridge and adjacent teeth with a putty and the cylinder, housing with set screw housing and longitudinal positioning guide are removed; and a longitudinal surgical sleeve with a first end, second end, an exterior and an interior wherein the first end has a platform, adjacent to the platform the exterior of the sleeve and contains circumferential male keyways, the interior defines a longitudinal tube sized to receive a drill, the positioning guide is removed from the surgical circular ring and second end of the surgical sleeve is placed within the surgical circular ring, seated and is turned clockwise wherein the male keyways of the surgical sleeve engage the keyway grooves of the surgical ring, the surgical sleeve is now positioned in the same position as the positioning guide occupied and functions as a drilling guide, successive sleeves with different size interior longitudinal tubes may be placed in exactly the same position relative to the edentulous dental ridge.
