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).
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.
