title: Handling of Polyvinylsiloxane Versus Polyether for Implant Impressions.
abstract: OBJECTIVE
  This study compared polyvinylsiloxane with polyether in handling dental impressions.
  
  
  METHODS
  Each participant (N = 39) made four impressions, each a combination of pickup and reseating techniques with polyether or polyvinylsiloxane, of one implant cast representing a specific clinical situation (tooth gaps, limited residual dentition, or edentulous jaw). Handling of impressions was subsequently rated by using a 12-item questionnaire with 100-mm visual analog scales.
  
  
  RESULTS
  While mean satisfaction scores were higher for polyvinylsiloxane than for polyether (69.5/63.0, P < .001), differences among subgroups were statistically significant only for pickup technique, limited residual dentition, and edentulous jaw.
  
  
  CONCLUSIONS
  Implant impressions made with polyvinylsiloxane using a pickup technique seem to be the best option for most clinical situations.
