Class II Cavity Preparation for Amalgam and Variations Introduction: Since the advent of restorative dentistry, management and treatment of posterior proximal caries lesion has posed great ... Class 2 Amalgam Slot Preparation - STUDYBLUE Class 2 Amalgam Slot Retention/Resistance form: 1. Cavity walls exit at ___ degree angles and parallel the ___ ___. 2. Retentive grooves are placed at a depth of ___ mm extending from the ___ floor to the ___ surface at the line angle formed by the axial wall and the proximal wall. Increasing the predictability and longevity of Class II resins Make small Class II tooth preparations! Unfortunately, one of the most-used burs for Class II preparations is a #557. This bur cuts a wide, right-angled slot in the tooth and, because of the cross-striations, makes ultrasonic vibrations in the tooth, potentially causing cracks.

Class 2 slot preparation Matrix bands and retainers • Contour, insert and place wedge • Purpose: Restoration of proximal contact • Types: Tofflemire, T-band, compositight* Condensing and Carving of Amalgam • Using an amalgam carrier, add increments and condense using positive finger rest. • Overfill prep and begin to carve and burnish the The strength of Class II composite resin restorations as ... 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. Restorations in the Primary Dentition and the Consequences of ... As seen by case one, slot preparations cannot withhold occlusal forces and therefore are more prone to leakage and reccurent decay. The use of stainless steel crowns is the most reliable restorative option available for primary teeth. Both cases two and three had deep class II composite restorations that led to leakage and reccurent decay.

Roggenkamp and others 9 first described the facial slot Class II cavity preparation for use with dental amalgam in 1982. This preparation, which involves accessing caries by the facial composite resin as a restorative material for facial slot prepara-tions, possibly because of isolation requirements, finishing

Fracture resistance of class II approximal slot restorations ... 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

CLASS II CAVITY PREPARATION CHARACTERISTICS OF AN IDEAL CLASS II Contact area carious lesion Proximal view Vertical section - Buccal view Class II carious lesions are diagnosed using bitewing radiographs. In reading a bitewing radiograph, it is important to know that a proximal lesion that appears to be 2/3 Operative Dentistry: Class II Cavity Preparation Operative Dentistry: Class II Cavity Preparation Introduction A Class II carious lesion develops apical to the contact area on the proximal surfaces of posterior teeth. The procedure for the removal of the carious lesion is the same as that of a class I. The first step is the development of the ideal cavity preparation. Predictable Restoration of Class 2 Preparations With In cases where initial caries is only on the proximal surface, a conservative slot preparation of the proximal surface combined with a sealant for the occlusal surface will suffice. When the caries extends into the occlusal pits and fissures or if an existing class 2 amalgam or composite resin is being replaced, an isthmus width of one fourth Fundamentals of cavity Preparation - SRM Institute of
