    How to use VITA Multifunctional Teeth to create new dentures in the upper and lower jaw

    How this denture tooth line leads to integrated esthetics and quality function for economical rehabilitations.

    Denture patients often ask for cost-effective solutions that simultaneously offer individual esthetics and proper function. Practitioners desire simple and reproducible set-ups that accomplish efficient workflows and offer their patients economical solutions without any issues. In order to fulfill all these expectations, choosing the right denture teeth is essential. In this case report, denturist and dental technician Daniel Lavrin demonstrates how VITA Multifunctional Teeth can be used to create new dentures in the upper and lower jaw.

    Clinical situation

    A 52-year-old male patient presented in the clinic with a fractured upper denture. During his first clinical visit, it became obvious that the old dentures had extreme functional deficits, including poor esthetics (Fig. 1). The denture in the lower jaw presented with missing teeth in regions 22 and 27 (in the lower cuspids), after the extraction of the patient’s natural teeth. No occlusal contacts on the right molars or a general substantial loss of the vertical dimension were visible. The Class III set-up didn’t offer functionality and stability. The denture teeth were severely abraded and looked dull. The patient didn’t use his lower denture because it didn’t offer stability when he talked or chewed. The upper and lower alveolar ridge presented signs of atrophy, resulting from extractions and a missing load (Fig. 2).

    It was determined to rehabilitate the patient with new dentures. The goal was to switch the bite to Class I in normal occlusion and to give the patient functional security. Denture fit and comfort as well as esthetics needed to be re-established.

    Clinical pre-treatment

    Alginate impressions were taken and anatomical models fabricated to create individual trays. The mucodynamic impression on the tray rim took place with rigid Impression Compound (Kerr Dental). In a second step, the bony anatomy was molded with low viscosity A-silicone using Virtual® Light Body (Ivoclar Vivadent). Master models were poured out and light-cured plates with a wax bite block were fabricated on them. The intraoral bite registration in centric position was realized with the A-silicone CADbite (Ivoclar Vivadent). The articulation of the master models was configured according to the bite registration, followed by the creation of the wax try-in (Fig. 3).
