Dental handpieces, fluoride varnishes, abutments up for comment

March 13, 2017

Dental professionals are invited to contribute their expertise by reviewing and commenting on two draft dental standards and one technical report.

The deadline for comments is April 22, and copies of the draft standards and technical reports are available via the ADA toll-free number, ext. 2506, or email, standards@ada.org.

The following documents are available for comment:

  • Proposed ANSI/ADA Standard No. 35 Dental Handpieces and Motors, a modified adoption of an international standard related to dental handpieces and motors. It covers all handpieces and motors used in dentistry for patient contact, regardless of their construction or power supply. It specifies requirements, test methods, manufacturer's information, marking and packaging.
  • Proposed ANSI/ADA Standard No. 117 Fluoride Varnishes, a modified adoption of an international standard on fluoride varnishes. This standard specifies requirements and their test methods for total digestible fluoride content in dental varnishes containing fluoride, intended for use in the oral cavity directly on the outer surfaces of teeth and fillings. It also specifies the requirements for their packaging and labeling, including the instructions for use. This standard covers fluoride varnishes to be applied by dental health care workers.
  • Proposed ANSI/ADA Technical Report No. 146 CAD/CAM Abutments in Dentistry CAD/CAM, which covers requirements and test methods for assessing safety, reliability, accuracy and reproducibility of patient specific computer aided-design/computer-aided manufacturing abutments designed for use, either for a manufacturer’s own implants or for use with implants from other manufacturers. It also covers guidelines for standardization of future products. The abutment is individually designed by a laboratory or doctor to be attached to an implant by means of an abutment screw. This document covers milling done at a central milling facility, at the dental lab or by an in-office milling machine.

The ADA has played a key role in the development of standards since 1928 and is an American National Standards Institute accredited standards developer.
