Aesthetics
The patient was summoned to come to the practice for the assessment of aesthetic results before finalizing the restoration. Aesthetic prototypes were placed inside the oral cavity of the patient and the dentist checked the aesthetics, phonetics, dimensions of the vestibular part and as a consequence – support of the upper lip. Central position, lateral movements and protrusion were also controlled. Shifts were made on the dental unit as at this stage teeth are fitted to wax (Fig. 3).
After receiving the patient’s consent – the prototype was returned to the laboratory. In order to conduct further works, the clinically modified dentures were fixed in a silicon key. Then, master models were placed in a flask and high-precision silicon was used to create a mold. After curing, the prototype and working models were removed from the flask.
To create a beam model and test aesthetic conditions, templates were digitalized using the laboratory scanner. The received files were uploaded into the software to model the basic structure to obtain anchoring elements in a plane parallel to the chewing plane (Fig. 4).
The beam was designed in such a manner that it is possible to place counters on it without the need to apply fitting adhesive. It also allows their potential replacement using a very simple method. The beam surface from the mucosal [...]
