Handling of Polyvinylsiloxane Versus Polyether for Implant Impressions

Dental implants are a valuable treatment option for rehabilitation after tooth loss. While optical, contact-free methods for taking implant impressions are increasingly gaining attention, conventional impressions are still considered the standard, with polyether and polyvinylsiloxane (PVS) the two impression materials most often used. Given the comparable accuracy of these materials under standardized conditions,1 other material properties, such as rigidity, viscosity, and polymerization time, become important in the individual dentist’s decision regarding which material to choose.2 These properties might influence the handling (ie, ease of use) for the dentist, hence they are important for a successful dental impression. The aim of this study was to assess and compare the handling of PVS and polyether.
