The Digital Process
At Master-Touch we pride ourselves on being pioneers in the field of digital dentures and partials. We use a variety of technologies, equipment and materials to provide high quality removable prosthetics from your digital impression, often in half the time it takes to fabricate traditional restorations.
step 1 - acquisition
Use your intraoral scanner to acquire a mucostatic impression of the patient's teeth and tissue. Be sure to capture adequate soft tissue for proper design of the denture base extensions and clasps. Some scanners may require an application of powder in order to reduce the glare of teeth and tissues during scanning. a scan of the opposing arch and an accurate bite registration should also be acquired during this appointment. If the patient does not have enough natural dentition to provide occlusal stops during the bite scan the vertical can be built up and held in place through the use of wax rims or impression material.
Most partial dentures can be fabricated using intraoral scans as final impressions. For full dentures, intraoral scans may be used to capture preliminary impressions that we will use to 3D print custom trays for the final impressions.
Send your scans to us using 3Shape Communicate, the 3M Connection Center, or send your STL files to us by e-mail.
Step 2 - fabrication
Valplast Partials - We will fabricate the majority of cases directly from your digital impression and bite scan without the need for a try-in. If indicated, a 3D printed prototype of the denture will be provided for the trial appointment.
Chrome and PEEK RPD Frames - The framework will be fabricated directly from your digital impression and bite scan. Teeth will be digitally designed and 3D printed with the gingiva in monolithic "blocks" that can be evaluated along with the fit of the frame during the trial appointment. After try-in, the final denture base will be processed with teeth.
Full Dentures - From your preliminary digital impression scans we will 3D print custom impression trays for you to take final impressions using the materials of your choice. Upon returning the final impressions to us, we will then fabricate wax rims on 3D printed baseplates for the occlusal registration appointment. Once we receive the bite rims, the denture will be digitally designed and a monolithic prototype of the teeth and gingiva will be 3D printed for a try-in appointment. Upon verification of the trial dentures we will mill the final denture based in acrylic and attach the final denture teeth.
