The shape or form of the conventional preparation that resist displacement or removal of the restoration from tipping or lifting forces. Principles: Depends on the restorative material Amalgam In most Class I and Class II, walls should converge occlusally. In class II, occlusal dovetail aid in . The cavity depth need be only 1 to mm for a high copper amalgam restoration. Make sure you have amalgam pluggers with very small working points so that you dont have to widen the cavity to provide convenience form. As an emergency measure, you can even cut off and flatten the tip of a straight probe to be used as amalgam condenser.
A(n) _____ is a small. oval-shaped matrix made of polished stainless steel that can be used for posterior amalgam and composite materials. Palodent The __________ is a matrix system designed to establish a temporary wall for the restoration of a class II restoration without the need to used it as a retainer. A Class II restoration must be completed to pass the WREB Exam. The restoration can be one (1) of the following: • Direct Posterior Class II Composite Restoration (MO, DO, or MOD) • Direct Posterior Class II Amalgam Restoration (MO, DO, or MOD) • Indirect Posterior Class II Cast Gold (inlay/onlay up to and including a ¾ Crown).

Indications. Amalgam is indicated for the restoration of a Class I, II, and VI defect when the defect (1) is not in an area of the mouth where esthetics is highly important, (2) is moderate to large, (3) is in an area that will have heavy occlusal contacts, (4) cannot be well isolated, (5) extends onto the root surface, (6) will become a foundation for a full coverage.
Class ii amalgam 1. Tooth preparation for class II amalgam restorations and its modifications 2. INTRODUCTION Amalgam although a brittle material, has been adequately serving as a restorative material since years, understanding of its properties and judgment of the preparation design are the vital factors controlling its use.

In relation to cavity depth and POS, this study shows that POS in deep cavity is more than medium and. Cavo-surface margins of the enamel (C C C) should all be bevelled about one-quarter length of the enamel rods for gold fillings and full length of the enamel rods for amalgam fillings.
1st Class Cavity 14 Cavity Preparation Fig. Illustrates 2nd class cavity prepared in upper bicus- pid. In the G.V. Black (GVB) amalgam Class I and II technique, occlusal margins in preparations are intrinsically obliquely transected, namely bevelled, because occlusal anatomy itself is inclined.
This generates an automatic enamel bevel in the occlusal preparation. But the proximal box walls feature butt margins that are 90 degrees to the cavosurface. Amalgam is a material that is commonly used for restorations; however, there are key features of the cavity that must be considered when preparing it for amalgam.
This post will look at these features and why they are relevant (generally for Class 1 cavities). 1. J.C. Rodda, Modern class II amalgam cavity preparations New Zealand Dent J () 2.

This study evaluates whether improvements in the physical properties of dental amalgam affect the use of Class II preparations without an occlusal dovetail.
Four amalgam alloys were selected providing combinations of particle shape and copper content. The amalgams were characterized for their h compressive and tensile strengths.

However, the impact of questionable and inadequate cavity preparations on the incidence of secondary caries was minor with regard to class II restorations made from amalgam. The gingival cavosurface bevel is a very important step to be performed in Class II cavity preparations for amalgam to remove the undermined enamel rods along the gingival cavosurface margin Preclinical dental training modules contribute to a major proportion of teaching hours in the undergraduate curriculum.
Class II Cavity Preparation for Amalgam When the lesion present in the proximal surface of premolars and molars, this requires class II cavity preparation, which is either MO or DO or MOD. If the carious lesion is present only in proximal surface and not involve the occlusal surface, the class II cavity should include all pits.

Class II Preparations. 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. Class II silver amalgam preparations will vary with the morphology, anatomy and extent of carious involvement of the individual tooth being restored.
However, certain fundamentals are common to all Class II silver amalgam cavity preparations. The Class II silver amalgam cavity preparation consists of: A- Occlusal segment and B- Proximal segment. To get the perfect Cavity you need to have the proper set of instruments to prepare the cavity and to restore it using any of the following filling materials – ZOE (temporary), GIC, Composite, Amalgam etc.

The fate of amalgam restoration is determined by geometry of the cavity preparation and cavosurface angle is one integral part of the cavity, which decides the marginal characteristics of the restoration and health of the tooth.
