Purpose: The aim of this study was to evaluate the improvement in mandibular complete dentures (MCD) stability using a modified neutral zone technique (MNZT). Materials and Methods: For 21 patients who were dissatisfied with their primary MCD, MCDs were fabricated using the MNZT. Results: Nearly all of the patients showed considerable improvement in oral health-related quality of life, and 85.7% of the patients stated an improvement in general denture stability and while chewing. A masticatory function test showed no significant changes. Conclusion: This MNZT seems to improve MCD function, especially in patients who cannot be treated with implants.
