For periodontal surgery programs building crown lengthening technique — screw-retained teeth and resorbable gingiva allow repeated flap, resection, and suturing practice on a single model.

The model is an upper arch with screw retained teeth, and we left an edentulous area in tooth # 8 and #11 for implant placement. The gingiva is made of a silicone rubber for realistic  suturing.  Another popular feature is the gingiva on the palate is made thicker, so you can practice palatal harvesting. Lastly, you can practice suturing on the model and when you are done the tissue is replaceable.
