Perceptions and experiences of patients following treatment with single-implant mandibular overdentures: A qualitative study.

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.
