3M ESPE has announced new indications for its Protemp Crown temporization material. Dentists can now use the preformed, malleable temporary crown for implant abutments and digital impressions, as well as for long-term temporization, the company said.
The material is currently used for creating single-unit temporary posterior crowns.
The crown can be used to offer patients a more natural-looking appearance after the healing and osseointegration of an implant has occurred, and before the final restoration is placed, according to the company.
Additionally, dentists who use digital impression devices can now use Protemp Crown to model pre-existing tooth structure and anatomy for use in digital imaging applications. The malleable, tooth-colored material requires no impression or matrix, and can be trimmed and adapted to custom-fit a crown preparation or implant abutment, according to 3M.
The company said it has new clinical data showing that Protemp Crown performs well in the mouth for up to one year, verifying its usefulness for long-term temporization. It cited a study evaluating the crown's performance that found that margin quality, proximal contacts, surface roughness, and occlusal wear all remained acceptable after six months and one year.
Protemp Crown is available in one universal shade and various preformed sizes. After adapting the crown to its oral environment, dentists light cure, polish, and cement using standard temporary cements. Additionally, Protemp Crown can be customized and/or repaired using a conventional flowable.
