Abstract
Twenty-two completely edentulous patients were selected from the Out-patient clinic of Prosthodontic Department, Faculty of Oral and Dental Medicine, Ain- Shams University. The patients were selected to evaluate their satisfaction after receiving two dentures one conventionally made with acrylic teeth and the other digitally constructed with High Impact Polymer teeth (HIPC).
At first, a conventionally constructed denture with acrylic teeth was constructed for each patient. Primary impressions were made using alginate impression material and special trays were constructed. Secondary impressions were made by using border tracing material and Zinc Oxide Eugenol impression Paste. Facebow record was registered and jaw relations were recorded in centric relation by bimanual manipulation and wax wafer technique. Setting up of the teeth were made followed by try-in and delivery of the conventional denture.
Then, a digitally constructed denture with HIPC teeth was constructed for each patient. During the try-in stage of the construction of each patient’s conventional denture, the Digital Smile Design protocol was followed creating a new smile design. This consisted of three frontal views, two profile views, a 12 O-clock view and an intra occlusal view. Facial analysis was made followed by dento-gingival analysis and the smile curve was established. The dental contour was made and the design was presented to the patient for his feedback. The master casts were scanned and future denture bases were designed and virtual setting was done. Then STL files of the designs were sent to the printing machine to produce the denture bases and milling machine to produce the HIPC teeth. The teeth were held together in position using a positioning key and they were cemented to the denture bases.
At the end of the study each patient was presented with OHIP-14 questionnaires one before with no dentures and one for each of the two dentures. Responses were recorded on a Lickert scale. According to the results both dentures showed significant improvement in the patient’s quality of life as compared to their edentulous state, but showed little or no significant differences on the patient’s quality of life scores despite being pleased with the digital denture’s esthetic result.
