Purpose: To investigate whether pretreatment patient satisfaction, oral health–related quality of life, or diagnostic complexity are predictive of a decision to choose implant treatment. Materials and Methods: Edentulous patients requesting dentures were enrolled in a prospective observational study. All subjects were provided with conventional dentures and then given the option to proceed with the placement of two mandibular implants and to have their prosthesis modified into an implant overdenture. Subjects were classified according to the Prosthodontic Diagnostic Index (PDI-CE) and asked to complete a Denture Satisfaction Questionnaire and the Oral Health Impact Profile for edentulous patients (OHIP-EDENT) at pretreatment, following the provision of new dentures, and following modification to overdentures. Results: Of the 125 subjects who had conventional dentures, 15 proceeded with implant treatment. The subjects who decided to have implants were not significantly different in terms of diagnostic complexity or level of satisfaction. Those who chose implants were significantly younger, had newer dentures, and had higher OHIP-EDENT scores at baseline. The most common reason for not being satisfied with dentures but avoiding implants was fear of surgery. Conclusion: The majority of subjects in this study were satisfied with conventional denture treatment, despite registering its limitations. Subjects who were more anatomically compromised were not more likely to choose implant treatment. It remains to be shown whether fear of surgery can be overcome in order to increase the uptake of implant treatment and improve patient outcomes.
