Improvement of surgical skills in students using a newly developed 3D printed osteotomy model of a partially retained wisdom tooth.
Article in BMC medical education, 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
objectivesAgainst the background of digitalization, practicing on 3-D models for dental education has become more important. To improve the surgical skills of dental students, this study aimed to develop a 3-D-printed model for osteotomy of a partially retained lower wisdom tooth and evaluate surgical skills of students with practical experience acquired through phantom exercises compared to students who acquired experience only by assisting oral surgeons. MATERIALS AND
methodsWe developed a 3-D model that allows dental students to perform an osteotomy of a partially retained real wisdom tooth in region 48. The model was evaluated by oral surgeons (OS; n = 5), students with phantom experience (PE; n = 26), and students with experience with clinical assistance (CE; n = 29). Additionally, student performance was rated.
resultsThe OS, PE, and CE groups all evaluated the model as suitable for student courses, except for the gingiva mask. The CE group developed slightly better. In the exercise, the PE group showed better incision results, while the CE group was slightly better in the preparation of the working field.
conclusionsThe osteotomy model is suitable for hands-on courses for dental students, but the gingiva should be improved. However, phantom exercise cannot replace clinical experience. CLINICAL RELEVANCE: To improve education, knowledge and self confidence of students in dental school.
