Abstract

Background: Periodontal surgery is part of the dental curriculum at German universities. A particular challenge is to provide a basic understanding of surgery. This is the first pilot study evaluating the extent to which regenerative therapy or lower molar hemisection can be learned using a specially produced 3D-individualised patient model compared to a porcine cadaveric model.

Methods: During the periodontal surgery block practical, 14 students performed lower molar hemisection and regenerative therapy with bone graft substitute (Bio Oss, Bio Gide; Geistlich Pharma AG, Wolhusen, Switzerland) on an individualised 3D model. Interventions were then evaluated using a validated questionnaire. Differences between groups were statistically assessed for individual items and the overall questionnaire using the Wilcoxon test (p < 0.05).

Results: In the overall evaluation, the 3D-printed patient and animal cadaveric model did not differ significantly, with the animal cadaveric model scoring a slightly higher score. The 3D-printed patient model was considered more realistic for the anatomical appearance of each part, being evaluated superior for practicing regenerative therapy, removing inflammatory tissue and performing molar hemisections. The animal cadaveric model was rated better for soft and hard tissue tactile feedback.

Conclusion: With the 3D-individualised model, hemisection and regenerative therapy can be performed realistically, but soft and hard tissue feedback still needs to be optimised. 3D models are useful for teaching periodontal surgery. In the future, if optimised, 3D printing could completely replace the animal cadaveric model, as it offers clear advantages (e.g., easier organisation, better hygiene).

背景:牙周手术是德国大学牙科课程的一部分。如何让学生对外科手术有基本的了解是一项特殊的挑战。与猪尸体模型相比,本试验研究首次评估了使用专门制作的三维个性化患者模型学习再生疗法或下磨牙半切除术的程度:方法:在牙周手术模块实践中,14名学生在个性化三维模型上进行了下磨牙半切术和使用骨移植替代物(Bio Oss, Bio Gide; Geistlich Pharma AG, Wolhusen, Switzerland)的再生疗法。然后使用有效问卷对干预措施进行评估。使用 Wilcoxon 检验对各组间的单项差异和整体问卷进行统计评估(P 结果):在总体评估中,3D 打印病人模型和动物尸体模型没有显著差异,动物尸体模型得分略高。3D打印病人模型被认为在各部位的解剖外观上更为逼真,在进行再生治疗、去除炎性组织和进行臼齿半切除术方面更胜一筹。在软组织和硬组织触觉反馈方面,动物尸体模型被评为更好:结论:使用三维个性化模型,可以逼真地进行半切和再生治疗,但软组织和硬组织的反馈仍需优化。三维模型对牙周手术教学很有帮助。未来,如果经过优化,三维打印可以完全取代动物尸体模型,因为它具有明显的优势(如更容易组织、更卫生)。

期刊介绍: The aim of the European Journal of Dental Education is to publish original topical and review articles of the highest quality in the field of Dental Education. The Journal seeks to disseminate widely the latest information on curriculum development teaching methodologies assessment techniques and quality assurance in the fields of dental undergraduate and postgraduate education and dental auxiliary personnel training. The scope includes the dental educational aspects of the basic medical sciences the behavioural sciences the interface with medical education information technology and distance learning and educational audit. Papers embodying the results of high-quality educational research of relevance to dentistry are particularly encouraged as are evidence-based reports of novel and established educational programmes and their outcomes.
