Dental instrument having overlapping helical scoring pattern
DCFirst Claim
1. A dental apparatus, comprising:
- a tubular, hollow metal handle with first and second ends and an exterior peripheral surface therebetween wherein first and second, different, helical scoring patterns are cut into the handle,first and second closing members wherein each closing member includes a body portion and an attachment portion, wherein each of the attachment portions slidably engages a respective hollow end of the handle and wherein the attachment portions are metallically bonded, without adhesive, to at least one adjacent region of the respective end.

Abstract
A dental apparatus or instrument includes a hollow, tubular metal handle, closing members fastened to opposite open ends of the handle, and tool parts connected to the closing members. The metal handle includes a central substantially smooth region and two surface contoured regions adjacent to the closing members. The surface contoured regions include wide grooves in a criss-crossed pattern superimposed on V-shaped narrow grooves in a criss-crossed helical pattern. The combination of the two type grooves gives a sure grip feel to the two surface contoured regions. The closing members each include an attachment portion which tightly interfits into an open end of the handle and which is brazed into the handle.
