Evaluation of volumetric wear loss and pain scores of the digitally and conventionally manufactured occlusal splints for individuals with sleep bruxism.
Trial report in Journal of applied oral science : revista FOB, 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
introductionAccording to the latest international consensus in 2018, sleep bruxism is the activity of the masticatory muscles during sleep characterized by rhythmic or non-rhythmic teeth clenching or grinding. Regarding its harmful effects, bruxism is considered one of the predisposing factors of tooth wear and temporomandibular joint diseases. Occlusal splint therapy is the most frequently used treatment for minimizing these harmful effects.
objectivesThis study compared the volumetric wear loss and pain scores between digitally and conventionally manufactured occlusal splints for individuals with sleep bruxism. METHODOLOGY: A total of 30 individuals diagnosed with sleep bruxism were selected following the inclusion criteria and randomly divided into two groups. Pain scores were subjectively reported using a visual analog scale. Volumetric wear loss of the occlusal splint surface was measured using the Geomagic software. Data were analyzed with SPSS version 25.0.
resultsAt the six-month follow-up, conventionally manufactured splints (103.53±41.23) showed a volumetric loss significantly higher than that the digital ones (62.33±26.29) (p=0.005). We found no significant difference between the two splint types regarding VAS scores.
conclusionOcclusal splint wear can gradually alter the balance of occlusal contact and potentially reduce its therapeutic effectiveness, highlighting the importance of using wear-resistant materials. Our findings indicate that digital manufacturing processes provide advantages due to their long-term clinical outcomes.
