Do implant overdentures improve chewing ability and quality of life despite no effect on nutritional status?
Article in Evidence-based dentistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
data sourcesThis prospective study involved 35 edentulous adults aged 50 years and older, treated at a dental clinic. Data were collected across four time points: baseline (T0), 3 months post-application of conventional complete dentures (CD; T1), and 3 and 6 months after the transition to implant-supported overdentures (IOD; T2 and T3). Patient outcomes were assessed using: Mini Nutritional Assessment (MNA): To evaluate nutritional status, Oral Health Impact Profile (OHIP-14): To measure oral health-related quality of life (OHRQoL) and Chewing Ability Questionnaire: To document functional improvements.
resultsMini Nutritional Assessment (MNA) scores declined initially after transitioning to CDs (T0-T1) but stabilized following implant overdenture placement. Significant improvements were reported, with chewing difficulty decreasing from 91.4% at baseline to 51.4% at T3. Marked enhancements in OHIP-14 scores at T2 and T3, indicating better oral health perception.
conclusionWhile implant overdentures significantly improved chewing ability and quality of life, they did not lead to measurable improvements in nutritional status. The findings highlight the functional and psychosocial benefits of implant overdentures for older adults, suggesting that oral rehabilitation enhances overall well-being even without direct nutritional effects. This study provides a moderate level of evidence based on its prospective design, validated outcome measures, and clear findings related to chewing ability and oral health-related quality of life. However, the small sample size, lack of long-term follow-up, and absence of significant improvements in nutritional status suggest the need for further research to validate and strengthen these findings. Future studies with larger populations and extended observation perimplant overdentures are essential to enhance the robustness and generalizability of the evidence.
