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 prevention", dentistry has taken long strides. It is high time we fully realised the importance of preserving healthy tooth structure. Restoring proximal caries lesions conservatively with tunnel ... Marginal ridges can develop crack lines prior to or during cavity preparation and can fracture after the restoration.25 In addition, overhangs may be formed on Class II composite resin restorations, and Frankenberger et al26 reported that the use of magnifying loupes was beneficial for reducing marginal overhangs by up to 40% in standard Class ... The New Science of Strong Teeth: Class II Preps | Dentistry Today The tooth, composite, and marginal ridges should deliver decades of excellent service to the patient without retreatments. Figure 20.
