Immediately loaded single-implant mandibular overdentures compared to conventional complete dentures: A...

Area of Science:

• Dental Implantology
• Prosthodontics
• Health Economics

Background:

• The single-implant mandibular overdenture (SIMO) presents a simplified alternative to conventional overdenture designs for edentulous patients.
• This study evaluates SIMO as a simplified implant intervention.

Purpose of the Study:

• To conduct a cost-effectiveness analysis of the SIMO compared to the conventional complete denture (CCD).
• To assess patient-reported outcomes and satisfaction over a 1-year period.

Main Methods:

• A randomized clinical trial compared SIMO with CCD.
• Costs were tracked for one year, and effectiveness was measured using OHIP-Edent and satisfaction scores.
• Incremental cost-effectiveness ratios (ICER) were calculated.

Main Results:

• The SIMO group showed significant improvements in OHIP-Edent and satisfaction scores, unlike the CCD group.
• SIMO incurred an 80.7% incremental cost compared to CCD (I$1,068.20 vs I$590.99).
• The ICER for SIMO was I$48.20 per 1-point reduction in OHIP-Edent and I$12.56 per 1-point increase in satisfaction.

Conclusions:

• The SIMO is an effective, simplified, and low-cost implant intervention for edentulous patients.
• SIMO is a cost-effective alternative to CCD, with potential to increase dental implant utilization among older adults with financial constraints.
