RESUMO

The objective of the research was to compare the intensity of the bite force, using an gnatodinamometer in edentulous patients that use superior complete denture and inferior Overdentures retained by clip bar system and to evaluate general satisfaction of these patients after the rehabilitation with the prostheses on implants through a questionnaire. The study was developed in two stages: the first part focused the mensuration of the intensity of the bite force in the area of the first molars on both sides, with the patient using the superior complete denture and the inferior overdenture and after the removal of the bar on implant, thus becoming a patient with a complete conventional denture. On average the maximum intensity of the bite force, obtained when the patient was with the bar (inferior overdenture) was of 8,9 Kgf, and when the bar was removed (prosthesis total bimaxilar) it was of 4,8 Kgf. notecing an increase of 100% practically in the intensity of the force with the placement of the prosthesis on inferior implant. In the second part a questionnaire was applied with the intention of comparing the capacity of the patient to chew certain types of foods with the old prosthesis and with the prosthesis on implant, and to evaluate his/her personal satisfaction. The results of the questionnaires demonstrated that 100% of the patients talked about difficulties regarding the mastication of raw carrot and peanut. However, with the prosthesis on implants, more than 91% reported to feel comfortable when chewing those foods. The percentages reached 100% for pudding, banana and apple. With the old prosthesis, the capacity to chew was reduced, as grades (0) zero and (4) four were attributed by more than 86% of the patients. As regards the prosthesis on implants, the evaluation of the capacity of chewing got much better as 100% of the patients attributed grades equal or superior to 8 (eight). This way it can be concluded that the rehabilitation with prostheses on implants in edentulous patients , provides an increase of the intensity of the bite force in more than 100%, in other words, the double in relation to conventional complete denture and the general satisfaction, regarding the treatment involving implants was great, as more than 95% of the patients evaluated the work with grades equal to 9 (nine) or 10 (ten).
