Study Notes

Rest Seat Preparations

Rest seat preparations should be made in sound enamel, following proximal guiding planes to eliminate undercuts.
Occlusal rest seats in sound enamel are prepared using burs and polishing points, aimed to achieve a smooth surface similar to the original enamel. A larger round bur is used initially to lower the marginal ridge and establish the rest seat outline.
A smaller round bur then deepens the occlusal rest seat floor, creating a spoon shape. Polishing points finalize the preparation contour.
Fluoride gel should be applied to abutment teeth after enamel re-contouring.
Occlusal rest seats in existing preparations can be widened to compensate for shallowness, but the floor should still be apically inclined from the marginal ridge. A secondary occlusal rest can be used if this isn't possible, placed on the opposite side of the tooth to prevent slipping.
Occlusal rest seats in new restorations, crowns or inlays, should provide clearance in the preparation.
Sufficient occlusal reduction is important to accommodate the rest seat depth in the abutment crown.
