Class II Composite Training Bundle – Upper & Lower Posterior Models

A complete 3D printable training bundle designed for practicing Class II composite restorations on both upper and lower posterior teeth. The bundle includes 4 training models: Upper reference + prepared teeth model Upper prepared-teeth practice model Lower reference + prepared teeth model Lower prepared-teeth practice model The preparations include premolars and molars with proximal and occlusal involvement, designed for practicing Class II composite build-up, proximal wall reconstruction, contact points, marginal ridges, and occlusal anatomy. The reference models allow the natural tooth morphology to be viewed while working on the prepared teeth, while the dedicated practice models provide a simpler setup for repeated exercises. Suitable for dental students, operative dentistry training, restorative courses, simulation labs, and individual practice. All models are designed for 3D printing and repeated training use.
