The complexity of rehabilitation for totally edentulous patients makes it necessary to devise treatment strategies that meet the patients' expectations in terms of function, esthetic, psychological, and social aspects. The aim of this study was to i) compare the satisfaction of edentulous patients who had been rehabilitated with implant-supported overdentures and fixed prostheses in the mandible, and ii) assess the technical aspects of the prostheses in relation to patient satisfaction. This was a cross-sectional study involving 30 patients, 15 of whom had been rehabilitated with implant-supported overdentures and 15 who had been treated with fixed prostheses. The patients answered the OHIP-EDENT questionnaire, validated for the Brazilian Portuguese language, to assess satisfaction. Also, patients underwent clinical examination to assess the condition of their prostheses. Statistical analysis using the Mann-Whitney U-test revealed no significant differences in satisfaction between patients with overdentures and those with fixed prostheses. Likewise, Fisher's exact test demonstrated no significant differences in patient satisfaction concerning the condition of the prostheses as evaluated by the prosthodontist. It was concluded that both types of prostheses were perceived as being equally satisfactory by edentulous patients, and that the condition of the prostheses did not influence individual satisfaction in terms of rehabilitation.

    • "The GOHAI scores after treatment were similar for individuals who underwent fixed or removable complete treatment. This was already demonstrated in previous studies using OHIP as a tool [32,39]. Finally, all the patients were satisfied about their chewing ability and the aesthetics. "

    ABSTRACT: Very few studies on the impact of implant therapy on Oral Health Related Quality of Life (OHRQoL) in partially edentulous patients have been published.Aim: This study aimed at analysing the improvement of OHRQoL of patients who underwent dental implant treatment using the "functional", "psychosocial" and "pain and discomfort" categories of the Geriatric Oral Health Assessment Index (GOHAI). Within a prospective cohort of patients rehabilitated with Straumann dental implants, the OHRQoL of 176 patients (104 women and 72 men) was assessed using the GOHAI questionnaire, at two different times, before and after implant placement. The degree of oral treatment was categorised into three classes: "Single Tooth Implant" (n = 77), "Fixed Partial Denture" (n = 75), "Fixed or Retained Full Prostheses" (n = 24). The participants' characteristics (gender, age, tobacco habits, periodontal treatment, time between both evaluations) were assessed. Before treatment, the GOHAI score was lower for participants with fewer teeth (F = 19, P < 0.001). After treatment, no difference was observed between participants; significant improvements were observed in the GOHAI scores obtained (repeated measures, analysis, (F = 177, P < 0.001)) for each of the GOHAI fields studied (functional, psychosocial and pain & discomfort), regardless of the degree of treatment. The best improvement was observed in patients who needed complete treatment (P < 0.001). The presence of preliminary periodontal treatment, tobacco habits, age and gender of the participants did not have a significant impact on OHRQoL. Changing the time between the two evaluations (before and after treatment) had no impact on the changes in the GOHAI score. Implants enhanced the OHRQoL of participants that needed oral treatment.

    • "Only a few studies have used OHIP- EDENT questionnaire, which is the most indicated version for edentulous patients wearing dentures. Zani et al. (2009) applied the OHIP-EDENT to evaluate the impact of overdentures and fixed prostheses on QoL, finding that both types of prostheses were perceived as being equally satisfactory by edentulous patients. Adam et al. (2007) showed that OHRQoL improved significantly in four (psychological discomfort and disability, social disability and handicap) of the seven domains after patients were provided with a new set of complete dentures.

    ABSTRACT: Objectives: The aim of this prospective, randomized clinical trial was to evaluate the effect of a minimally invasive implant procedure for denture stabilization on patients' quality of life (QoL). Materials and methods: Thirty totally edentulous patients were selected for this study. All prostheses were adjusted and relined before randomization and allocation to treatment either with two small diameter implants (SDI) - retained overdenture (study group) or non-intervention group (control group). Quality of life was assessed using the Oral Health Impact Profile-EDENT (OHIP-EDENT) questionnaire before intervention and at one-year follow-up. Between-group comparisons were carried out using the non-parametric Mann-Whitney test. Results: Magnitude of change in the OHIP-EDENT total score at one-year follow-up was 25.4 ± 10.7 for the study group, revealing a statistically significant difference with the control group, that showed a change of 9.5 ± 8.3 (P = < 0.001). Conclusions: After one-year follow-up, patients wearing mandibular overdentures with two minimally invasive splinted SDI, experienced more improvements in perceived oral health-related quality of life, than patients having conventional treatment.
