Intended Use

The Codent Low Speed Dental Handpieces and Accessories are intended for removing carious material, excess filling material, cavity and crown preparation, finishing tooth preparations and restorations, root canal preparations and polishing teeth.

Device Story

Codent Low Speed Dental Handpieces and Accessories consist of air motors, straight handpieces, and contra-angle handpieces. Devices are air-powered; used in dental clinics by dental professionals. System components include air motors (AI4C, AI2N, AE4N, AE2N) and various handpiece attachments (LAISAI, LBIPA1, LEIPD4, LEIPC4, LAESA2, LDEPA2). Air motors operate up to 25,000 rpm; handpieces feature gear ratios of 1:5 and 1:1 with maximum speeds of 200,000 rpm and 40,000 rpm respectively. Clinicians use these tools to perform restorative procedures, cavity preparation, and tooth polishing. The mechanical action of the rotary instruments facilitates the removal of dental tissue and restorative materials, aiding in the restoration of tooth structure and oral health.
