Abstract
A dental instrument for performing a variety of procedures includes an elongate, rigid body and a bit. The body preferably includes an axial bore and at least one lateral bore. The axial bore holds the bit so that it extends outward along the longitudinal axis of the body. The lateral bore holds the bit so that it projects laterally outward at an acute angle to the longitudinal axis.
Claims29
A dental instrument comprising:
- an elongate, generally linear, rigid body having a, longitudinal axis and first and second ends, said body also having a first lateral bore extending in said body at an acute angle to said longitudinal axis and proximate said first end, a second lateral bore extending in said body at an acute angle to said longitudinal axis and proximate said second end, and an axial bore extending inwardly from one of said ends generally along said longitudinal axis;
- a bit having a mounting end secured within one of said bores and a working end opposite said mounting end, said bit projecting laterally from said body when said mounting end is sectored in one of said lateral bores;
- and
- a securing element for engaging said mounting end to hold said bit in one of said bores.

A dental instrument comprising:
- an elongate rigid body having a longitudinal axis, said body including a bore extending therein at an acute angle;
- and
- a bit having a longitudinal axis and secured within said bore so as to project laterally from said body at an acute angle to the longitudinal axis of said body and terminating in an end surface for engaging a tooth or a dental article, said engaging end surface lies in a first plane that extends perpendicular to the longitudinal axis of said bit such that a second plane extending perpendicular to the first plane and along the length of said engaging end surface bisects the longitudinal axis of said bit and forms an acute angle with the longitudinal axis of the body.
