SUMMARY:

This study aimed to identify the factors that influence the decision to replace a conventional mandibular complete denture by treatment with dental implants, as well as to evaluate satisfaction, quality of life and masticatory performance (MP) after rehabilitation with overdentures with a single implant in adapted and not adapted to conventional mandibular complete denture (PT). Initially, a cross-sectional study was carried out with 117 users of conventional complete dentures (PTs), who were evaluated for outcomes related to the denture (number of anterior mandibular PTs, time of use of the current denture, whether the dentures were made by a dentist and regarding regular use of the mandibular prosthesis) and regarding the period of mandibular edentulism, mandibular bone height and the patient's willingness to undergo implant therapy. Among these patients, 22 patients who were interested in undergoing therapy with implants were selected, being allocated by pairing into 2 groups: adapted to the mandibular prosthesis (PTA Group - "adapted to mandibular PT") and non-adapted (PTN Group - " not adapted to mandibular PT”). In each patient, a single implant was installed in the midline and after the osseointegration period, the mandibular prostheses were converted into overdentures. Masticatory performance was evaluated by the sieve method, mandibular bone height by paranoid radiographic measurement, satisfaction by quantitative scale with a validated questionnaire and the impact of oral health on quality of life by the OHIP-Edent-19 questionnaire. The chi-square test was used for data analysis and the prevalence ratios adjusted by means of multivariate Poisson regression, with a confidence interval of 95% in the second, for the statistical analysis in each group and between groups, non-response tests were used. -Wilcoxon and Mann-Whitney parameters, with a significance level of 5%. Seventy-eight participants (66.7%) were interested in implant-supported mandibular PT, mean age 65.68±6.38, predominantly female.PM was not influenced by the choice of mandibular implant-supported PT. Preference for mandibular implant-supported PT was correlated with longer experience in mandibular PT (p=0.021) and was significantly associated with dissatisfaction regarding retention (p=0.005). After the implant intervention, all non-adapted patients became adapted. There was no difference between PTA and mandibular PTN for OHIP-Edent (p=0.276) and PM (p=0.222), satisfaction was significant only for the criterion “comfort in the lower arch” (p=0.043). For pre- and post-treatment comparisons with overdentures, the median total OHIP-Edent decreased significantly in both groups. In the intragroup comparison, this reduction was significant in PTA only for “functional limitation” (p=0.026), and in PTN in almost all domains, except “social dysfunction” and “disability” (p>0.05). There was a statistically significant increase in overall satisfaction from 75.41 to 90.25 (p=0.012) in PTN and from 76.10 to 90.50 (p=0.007) in PTA. The parameters “chewing”, “adaptation”, “retention” and “comfort” in the lower arch were significantly different in both groups, and “gustation”, “phonation” and “pain” in the lower arch were significant only for the group not adapted (p<0.05). There was a significant difference for PM in PTN (p=0.002) and PTA (p=0.047) when comparing the type of rehabilitation. There was no correlation between PM and OHIP before and after rehabilitation (p>0.05). It can be concluded that the previous experience with conventional mandibular PT and the dissatisfaction with the retention of these, influence the will of rehabilitation with mandibular implant-supported overdenture, as well as, rehabilitation with overdenture on single implant presents itself as an alternative for patients not adapted to mandibular conventional PT, helping to accept the use of mandibular prosthesis, as well as proving a positive effect on satisfaction, quality of life and masticatory performance.
