Comparison of Increase in Masticatory Efficiency Between Removable Partial Dentures Retained With Clasps and Retained With Attachments.
Article in Clinical and experimental dental research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectivesThis study aimed to evaluate and compare the masticatory efficiency of removable partial dentures (RPDs) retained with clasps versus those retained with attachments. MATERIAL AND
methodsA total of 107 patients fitted with 138 RPDs participated in the study; 87 RPDs (63.0%) were clasp-retained, and 51 RPDs (37.0%) were attachment-retained. Subjects chewed 5.0 g of peanuts for 30 s, and masticatory efficiency was measured using a spectrophotometer at an absorption rate of 590 µm. Measurements were taken before insertion, immediately after, and 1 and 3 months post-insertion of RPDs.
resultsThe analysis revealed progressive masticatory efficiency improvements for both clasp-retained and attachment-retained RPDs over time, with significant enhancements observed at the 3-month post-insertion mark. Initially, clasp-retained RPDs showed slightly higher efficiency than attachment-retained RPDs; however, attachment-retained RPDs demonstrated superior efficiency after 3 months (p = 0.001). Consistent improvements were noted across different denture support types, with Triangular and Quadrangular supports showing the most notable gains by 3 months (p ≤ 0.006). GLMM analysis underscored the significant impact of time on masticatory efficiency (F(3, 511) = 4.926, p = 0.002), with no significant effects attributed to RPD type or support type alone, nor any significant interaction effects, indicating a universal improvement in masticatory function over time regardless of RPD design.
conclusionsRPD insertion significantly improves masticatory efficiency, particularly evident 3 months post-insertion, with attachment-retained RPDs outperforming clasp-retained types. Improvements in masticatory function over time are consistent across all RPD designs, unaffected by denture type or support structure. This emphasizes the role of denture design in both immediate adaptation and long-term treatment success, suggesting that time significantly contributes to enhanced masticatory efficiency regardless of RPD design, highlighting the importance of tailored prosthetic rehabilitation.
