Abstract
Abstract An apparatus for guiding a dental instrument in drilling, in the alveolus of a patient, a second longitudinal perforation that is parallel to a first longitudinal perforation. The apparatus includes (a) a first shaft having a lower portion that is insertable into the first longitudinal perforation, an upper portion and a butt therebetween, the butt having a diameter that is greater than a diameter of the lower portion such that the butt abuts a surface of the jaw of the patient with the lower portion inserted into the first longitudinal perforation; (b) sleeve defining a longitudinal bore for receiving another shaft, the sleeve having a bottom surface and a top surface; (c) first arm for connecting the upper portion of the first shaft to the sleeve with the bore disposed parallel to the first shaft and with the bottom surface of the sleeve disposed above the butt with the first shaft in a vertical orientation such that, when the first shaft is inserted in the first perforation with the butt abutting the surface of the jaw of the patient, the bottom surface of the sleeve is spaced above the jaw; (d) a second shaft insertable into the bore; and (e) second arm means, including a second arm, for connecting an upper end of the second shaft to a head of the dental instrument such that the second arm is disposed above the top surface of the sleeve with the bore disposed in the vertical orientation and with the second shaft inserted in the bore.

Claim 8
Dependent Claim
283 words
A process for guiding a dental instrument in drilling, in the alveolus of a patient, a second longitudinal perforation that is parallel to a first longitudinal perforation, said process comprising the steps of: (i) inserting into the first longitudinal perforation a lower portion of a first member, said first member comprising (a) a first shaft having said lower portion, an upper portion and a butt therebetween, the lower portion having a diameter that is smaller than a diameter of the first perforation and the butt having a diameter that is greater than the diameter of the first perforation such that the butt abuts a surface of the jaw of the patient with the lower portion inserted into the first longitudinal perforation, (b) a sleeve defining a longitudinal bore for receiving another shaft, said sleeve having a bottom surface and a top surface; and (c) a first arm, connecting the upper portion of the first shaft to the sleeve with the bore disposed parallel to the first shaft and with the bottom surface of the sleeve disposed above the butt such that the bottom surface of the sleeve is spaced above the jaw; (ii) inserting into the bore a second shaft of a second member, said second member comprising said second shaft and further comprising a clamp for connecting the second member to a head of the dental instrument and a second arm connecting an upper end of the second shaft to the clamp such that the second arm is disposed above the top surface of the sleeve with the second shaft inserted in the bore; (iii) connecting the clamp of the second member to the bore; and (iv) drilling the second longitudinal perforation.
Claim 9
Dependent Claim
283 words
A process for guiding a dental instrument in drilling, in the alveolus of a patient, a second longitudinal perforation that is parallel to a first longitudinal perforation, said process comprising the steps of: (i) inserting into the first longitudinal perforation a lower portion of a first member, said first member comprising (a) a first shaft having said lower portion, an upper portion and a butt therebetween, the lower portion having a diameter that is smaller than a diameter of the first perforation and the butt having a diameter that is greater than the diameter of the first perforation such that the butt abuts a surface of the jaw of the patient with the lower portion inserted into the first longitudinal perforation, (b) a sleeve defining a longitudinal bore for receiving another shaft, said sleeve having a bottom surface and a top surface; and (c) a first arm, connecting the upper portion of the first shaft to the sleeve with the bore disposed parallel to the first shaft and with the bottom surface of the sleeve disposed above the butt such that the bottom surface of the sleeve is spaced above the jaw; (ii) inserting into the bore a second shaft of a second member, said second member comprising said second shaft and further comprising a clamp for connecting the second member to a head of the dental instrument and a second arm connecting an upper end of the second shaft to the clamp such that the second arm is disposed above the top surface of the sleeve with the second shaft inserted in the bore; (iii) connecting the clamp of the second member to the bore; and (iv) drilling the second longitudinal perforation.
