Objective: The aim of this study was to assess the influence of patient characteristics on edentulous subjects' preferences for different prosthodontic treatments with implants., Materials and Methods: A cross-sectional study was carried out with 131 edentulous subjects referred for treatment at a university clinic. Participants received detailed information about available treatment options and were asked to rank their preferences among three alternatives for rehabilitation of the maxilla and mandible: conventional dentures (CD), 2-implant-retained overdentures (IOD), or 4-implant fixed dentures (IFD). Individual data and prosthodontic-related variables were assessed through interviews. Oral health-related quality of life impacts was measured using the Brazilian version of the Oral Health Impact Profile for edentulous subjects (OHIP-Edent). Descriptive statistics, bivariate tests, and binary and multinomial logistic regressions were used for data analysis., Results: The majority of participants chose CD as their most preferred treatment for the maxilla (45.8%), while IFD was the most prevalent choice for the mandible (38.9%). Regression analysis showed that the OHIP-Edent "oral pain and dysfunction" (OPD) domain scores were positively associated with IOD preference for the maxilla (OR = 1.31; p = 0.010) and mandible (OR = 1.46; p = 0.002) and with IFD preference for the mandible (OR = 1.20; p = 0.031). Subjects with lower levels of formal education and those with lower income levels were less likely to choose IFD., Conclusion: Level of education, income, and perceived quality of life impacts are potentially predictive variables of edentulous patients' preference for rehabilitation with implants. These factors may constitute important aspects to be considered by clinicians when treatment planning for edentulous patients., (© 2019 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objective: This study aimed to explore the perceptions and long-term experiences of edentulous patients rehabilitated with single-implant mandibular overdentures (SIMO)., Methods: Thirteen participants, mean age 65.7 years, 69.2% women, who had had their treatment completed for at least 1 year, were invited and included in the study. Focus groups including four to five participants each were conducted, audio and video recorded and transcribed verbatim. Subsequently, the transcripts were analysed according to the principles of thematic analysis., Results: Four major themes emerged as follows: before decision to undergo treatment with SIMO, implant surgery experience, perception of treatment outcomes and impressions about the care received. Lack of information, cost, comorbidities, older age and fear were initial barriers to the decision for treatment. Dissatisfaction with previous treatment and a sense of opportunity motivated the decision. There were ambivalent reports of absence of pain during surgery and discomfort during anaesthesia. Post-surgical recovery exceeded the pre-surgical negative expectations in most cases. There was a tendency for a positive impact of SIMO on the patients' quality of life, comprising improved ability to chew and communicate, dietary diversification, greater comfort and safety, increased self-confidence and social interaction. Few minor inconveniences were reported such as the feeling of insecurity after an episode of denture fracture and the need to use adhesive paste. Satisfaction with the care received and the trust in the dentist and dental team were evident., Conclusion: In general, participants presented positive perceptions and rewarding experiences after rehabilitation with SIMO., (© 2018 John Wiley & Sons A/S.
