Background Edentulous patients with severe bone loss encounter lower complete denture (L-CD) instability problems. Mini dental implant (MDI) retained L-CDs are an alternative treatment for unstable L-CD patients. This study subjectively and objectively evaluated masticatory efficiency before and after MDI retained L-CD treatment. Materials and methods The subjects received 4 MDIs in the anterior mandible to retain their L-CD. Masticatory efficiency was evaluated after using their L-CD at least 3 months prior to MDI placement, 1 month after L-CD loading, and 3 months after L-CD loading. The subjective evaluation used a four-point rating scale questionnaire to assess chewing performance to generate the çPerceived Chewing Ability Scoree (PCAS). The objective evaluation used a two-colored wax cube analysis method, determining the çPercentage of Chewing Abilitye (PCA). Results The median PCAS and mean PCA values increased through Tests 1, 2, and 3. There were significant differences (p ≤ 0.001) between before and after MDI retained L-CD treatment in both evaluations. Conclusions All L-CD patients subjectively and objectively improved their masticatory efficiency after MDI placement. Our results suggest that minimally invasive MDI treatment is an attractive option for patients with L-CD instability problems, leading to improved masticatory efficiency and quality of life.
