A standard MOD slot-type tooth preparation was applied to 30 extracted maxillary molars. A modified sandwich restoration was used, in which the enamel/dentin bonding agent was applied first, followed by a Ketac Molar or Fuji II LC base …
2.1. Cavity Preparation. Class II mesioocclusal cavities were prepared using straight and pear shaped diamond points.Packable composites are indicated for posterior stress bearing areas due to their less polymerization shrinkage and improved handling properties, with an application technique similar... Class II composite marginal ridge failure: conventional vs.… This study evaluated the force necessary to cause failure at the marginal ridge of teeth prepared with conventional class II cavity design and teeth prepared with proximal box-only or vertical slot preparation. The teeth were restored with Herculite XR or Tetric Ceram. Mean failure loads were not...

CLINICAL IMPLICATIONS. A slot-type preparation should be used as a routine practice for small approximal caries in posterior teeth. From the fracture resistance point of view, composite restoration should be preferred in Class II slot preparations. Class II - Composite Techniques - Photo Galleries | Cosmedent ... CLASS II. The above amalgam replacement illustrates a standard Class II posterior composite restoration. The first step in this technique is to remove the old amalgam from the tooth. Then place a radiopaque cavity liner (Cosmedent’s Renamel De-Mark) on the tooth so that you can Predictable Restoration of Class 2 Preparations With ... The occlusal cavosurface margins were at right angles to the cusp ridges. This right angle margin allows for a bulk of composite resin at the high-stress-bearing occlusal margin that will prevent fracture of the composite resin. Also, beveling the gingival margin of a class 2 composite resin preparation should be avoided, even if it ends on enamel. Steps Of Cavity Preparation - SlideShare Steps Of Cavity Preparation 1.

This study evaluated the load, applied to the marginal ridge, required to produce failure in Class II posterior composite resin restorations with four different preparation designs. In group 1, the preparation had an extension through the occlusal groove. The other three groups employed a proximal box-only (slot) preparation. Cavity preparation factors and microleakage of Class II ... Purpose: To determine if alteration of any of the following factors could reduce microleakage following placement of Class II resin-based composites (RBC) at intraoral temperature: cavity preparation (vertical wall bevels), finishing technique (delayed vs. immediate), or postoperative re-bonding (marginal sealing).
