This is how we, as clinicians, obtain a good-fitting set of dentures - with well-adapted, accurate impressions that fully capture all of the fine details of the patient’s anatomy and an impression that has suction when removed from the mouth.Ĭurrently, there are case studies in the dental literature that have fabricated impression-free dentures utilizing scanners that are available now. We also have the patient move their tongue and cheeks in the early stages of the impression setting to capture the range of motion.

Dentists typically adapt or customize the impression tray to approximate the patient’s anatomy and use an impression material that will capture the full depth of the vestibule. Can a digital scanner accurately record the full depth of the vestibule and the range of motion of the soft tissue while in function in order to fabricate a denture that fits well?Ĭonsider what we have to do when taking a physical dental impression for dentures. Some patients have moveable mucosa that extends well onto the crest of the mandibular ridge. All of the soft tissue and muscle attachments move in function. Other than the hard palate and alveolar ridges, there really are no other stationary landmarks. And if the fit doesn’t work out as expected, the denture can be altered with a chairside denture reline - which you are going to do anyway.ģD dental impressions for the fully edentulous patient. It gives you the opportunity to develop a reproducible scanning technique that works well in your hands.
As a clinician who has literally made thousands of immediate and replacement dentures over the course of my career, if I were going to delve into taking impression-less dentures today, this is where I would start.
Since immediate dentures will require relining as healing progresses, it makes sense to test the digital impressions for complete dentures technique on an immediate denture case. The clinician in this article thoroughly scans the patient’s teeth and tissue that is affixed to the bone and scans the periphery of soft tissue directly adjacent to the hard tissue.įrom a practical standpoint, an immediate denture doesn’t have to fit perfectly because the tissue and underlying bone are expected to shrink and change with healing. Saiki, DDS, published in Glidewell’s Chairside Magazine. This technique was demonstrated in an article by Dean H.
#Impression dental care software#
The scans are saved into STL (standard tessellation language) files and sent electronically to the denture lab where specialized software is used to “print” 3D models that can be articulated into centric occlusion. If the patient has some natural teeth that occlude, it is possible to reproduce most everything present in the mouth digitally without taking immediate denture impressions for dentures or a bite registration.
That is because current intraoral scanners work well at capturing accurate digital images of the teeth and other hard tissues present in the mouth if the clinician systematically scans the mouth without creating overlap and distortion. If you plan to fabricate immediate dentures for a patient who still has most of his teeth, digital impressions will work. It depends on what dental appliances you are providing. Has technology progressed to a point that polyvinyl siloxane and rubber base impressions are a thing of the past? The answer is yes and no. digital Impressions: which ones work best to make a set of dentures that fit well?
