摘要

#CMT# #/CMT# The dental drill has a head (1) provided with cutting edges and having a rounded basic form. Two of the cutting edges cross over at a front side in an intersection cutting edge. The drill is made from a plastic material, which exhibits hardness between 60 and 250 Knoop. The cutting edges are formed in such a manner that the dental drill cut with soft material. The plastic material is strengthened with fibers such as glass fibers and carbon fibers. #CMT#USE : #/CMT# Dental drill. #CMT#ADVANTAGE : #/CMT# The dental drill is produced in a simple and cost-effective manner. The efficiency of removal of diseases during cavity preparation is improved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view of a dental drill with a spherical head. 1 : Head 6 : Shank #CMT#INDUSTRIAL STANDARDS : #/CMT# The hardness measurement of the dental drill according to Knoop refers to DIN EN ISO 4545 #CMT#POLYMERS : #/CMT# The dental drill is manufactured from polyoxymethylen (POM), polycarbonate (PC), polyethermid (PE), polyether sulphone (PES), polysulphone (PSU), polyamide-imide (PAI), polyphenylsulfone (PPSU)or polyetheretherketone (PEEK).
