ABSTRACT
The number of patients treated with total removable dentures is still high, despite the development in the field of implantology. A 68-year-old patient with loose dentures and complaints regarding pronunciation and phonetic came to the University Dental Clinic with the wish to construct new stable dentures. In clinical examination, moderate resorption of the lower residual ridge was observed. In order to achieve optimal stability and retention, the construction of new dentures was done using the third impression technique. The following procedures were done: The primary impression was made with alginate. The individual trays were constructed and sectional border molding was done. After constructing the master cast, the base and the occlusal rims were prepared. The record with the face bow was done. The piezography impression was achieved by instructing the patients for the phonetic exercises. During the third impression, the periprosthetic organs left their impression during the phonetic movements. By respecting the neutral zone, the surrounding tissue supports the denture. The forces applied by the tongue are balanced by the forces applied by the cheek and lips. The area where the artificial teeth would be arranged was registered. During the try-in stage, another impression was taken with light silicone to check for the piezographic technique. After confirming aesthetic and centric occlusion, the traditional flasking and polymerizing procedures were done. Immediately, in the insertion phase the patient reported improvement of stability and improvement of the phonetic was observed. The number of adjustments were minimal. The reported satisfaction of the patient was also confirmed clinically by two experts in the field and the satisfaction of the patient was re-confirmed again after 1 weeks, 2 weeks, 1 month and 6 months. This is a clinical case that highlights the importance of the use of the third impression in order to increase the outcome of the total removable dentures.
