Preparation for composite Preparation for composite differs from preparation for amalgam as follows: we do not create undercuts and we bevel enamel in the proximal cavity. We bevel axial walls and also the outer edge of the gingival step if it is located in the enamel part of the tooth. If the gingival step is located Class II Resin Restorations: Quick Tips to Help Manage the ... Another big challenge, if not one of the biggest ones, in placing and doing a great class II resin restoration, is to get ideal contours and ideal interproximal contacts. If you are like me, I learned using the good old tofflemire matrix, which had been used forever doing class II amalgams, and it worked great…..for amalgams!

Mainly the idea that if you prep a class II in the Black or slot way you have predisposed the tooth to fracture, regardless of material? Or is there a way to perform these preps skilfully to avoid these fractures for a very very long time? Also you talk putting an amalgam in a composite prep and how that's the reason for the cracks.

When the Class II procedure accounts for almost half of direct restorations 1, it’s time to rethink what it means to your practice.The new Class II Total Practice Solution by Dentsply Sirona is the only comprehensive Class II approach for more efficient clinical outcomes and bottom-line results. Increasing the predictability and longevity of Class II resins A reader is disappointed in the composites he places for Class II resin restorations and asks what he can do to avoid postoperative sensitivity, reduce open margins, and ensure there is no more recurrent caries on the gingival margins. Dr. Gordon Christensen says the resin-based composite restorative materials we have today are very good and that, in his opinion, the problem is you and me.

This was done using a 5th generation bonding agent, so total etch was done, starting with the enamel (10 sec) then dentin (10 more sec). Can also be done wit... Facial Slot Class II Restorations: A Conservative Technique Revisited 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 approach, followed the instrumentation sequence used for Class III preparations. When first presented, the facial slot preparation was considered ultraconservative because it allowed the most direct access to caries. Because amalgam was the recommended restorative material, mechanical retention was required ... Predictable Restoration of Class 2 Preparations With Composite Resin ...

Academic Studies | Directa Abstract: The aim of the present study was to evaluate the effect of iatrogenic preparation damage on the need for operative caries treatment of approximal surfaces, adjacent to Class II amalgam restorations. Changing concepts in Class I and II cavity preparation… From the time G V Black, father of Operative Dentistry outlined the principles of cavity preparation, and stressed on "extension for preventi
