I just took Dr. Joseph Massad’s course on making impressions for complete dentures. He uses unique trays that he has designed for the edentulous arch that are disposable and made out of plastic. You can heat them and then mold them to the desired shape. You can trim them easily with a vulcanite bur. He teaches a multi-step protocol for using different viscosity polyvinylsiloxane impression materials to make the final impression. Have any of you tried his trays and used his impression technique? What is your experience?
Editor’s Note: According to Dentsply:
“With the Massad edentulous impression tray, Aquasil Ultra Smart Wetting impression material and the Massad Technique, accurate custom tray impressions can be obtained in one visit. In the past, edentulous impressions were either too rigid or too wet. Rigid material compresses the soft tissue while very wet material doesn’t capture the needed muscular detail. The marriage of the Massad impression tray and technique and Aquasil Ultra impression material has resolved both of these issues.
Joseph Massad, DDS, has invented an impression tray and technique which allows the usage of multiple viscosities of Aquasil Ultra impression material in one disposable tray – capturing all the detail needed to create a perfectly fitting full set of dentures. When used with the Massad technique and tray, Aquasil Ultra impression material affords the clinician the optimal outcome.”
