You can scan impressions within a patient’s existing complete removable prosthesis reliably, predictably, and efficiently. While TRIOS scanners have been optimized to effectively scan these impression surfaces in a seamless, integrated manner, a designated scan strategy will render excellent scan results and a high-quality definitive prosthesis.
The reference denture technique is preferred by clinicians and technicians globally for its seamless, technically and clinically integrated workflow. This scan strategy delivers increased patient acceptance and satisfaction, reduces postoperative adjustments, and ultimately improves the patient experience as it requires fewer visits to the clinic. To understand how to obtain the best possible scans, you must designate distinct strategies for the maxilla and mandible, which will be described in detail in the scan strategy.
Quick Tip: allow time to render
After you have captured the internal alveolar ridge width and depth, allow these scans to render. When you begin to re-scan the peripheral borders, keep the 2D live image, so that at least one third of the window is positioned over the already aligned alveolar ridge scans and no more than two thirds is positioned over the new scans.
Proper strategy is required to achieve global accuracy in scanning the maxillary impression within the prosthesis due to its wide surface and anatomical features, including palate shape, undercuts, and ridge form. Fortunately, this can be handled easily.

The goal of scanning the mandibular impression within the prosthesis is to achieve global accuracy. This goal is achiev-able, but it requires a proper strategy due to the mandibular impression’s narrow surface and anatomical features, like the retromolar pad, alveolar ridge, lingual borders, and undercuts.

The goal in scanning the occlusion is to ensure adequate alignment of the maxillary and mandibular reference dentures in centric occlusion. This can effectively be accomplished by conducting the occlusion scan in two manners:
Personally, I prefer the bite scan feature for its predictability, efficiency, and accuracy. The feature involves simply scanning the maxillary and mandibular reference dentures either intra- or extra-orally. I prefer to conduct this method by using a rigid bite registration material and capturing the patient’s repeatable unstrained centric relation record.
