Introduction:
Health-conditioned quality of life determines patient’s self-assessment concerning the impact of the disease and treatment on their functioning in physical, mental and social aspects.

Aim of the study:
To assess the impact of the design of dentures made according to two different methods of clinical and laboratory practice on the quality of life of edentulous patients.

Material and methods:
The study material consisted of a group of sixty toothless patients (58 to 68 years old) of both sexes, using full dentures. The patients were divided into two groups: Group I (30 patients) in which full dentures made according to the biofunctional method were used Group II (30 patients) in which dentures made according to the Cracow modification of the calotte method were used. All the patients were interviewed, the physical examination was conducted together with the clinical evaluation of prosthetic restorations used so far. The General Oral Health Assessment Index (GOHAI) questionnaire was used to subjectively assess the quality of life associated with oral health, and patients in both groups were surveyed before and after treatment. The obtained results were subjected to statistical analysis.

Results:
Better comfort of using dentures was reported by patients using dentures made according to the BPS system.

Conclusions:
The betterment of the quality of life in patients using full dentures is associated with the denture design, which improves chewing performance and aesthetic appearance. In patients using full dentures, the quality of life is statistically significantly better after the application of dentures made according to the biofunctional system.
