How To Achieve Optimum Proximal Contact and Good Anatomy in Class II Composite Resin Restoration?

The caries classification system by GV Black categorizes caries into six classes based on their location. GV Black Class II caries can affect the occlusal, mesial, and distal surfaces, including MO (mesio-occlusal) and MOD (mesio-occlusal-distal) lesions.

The primary requirements for posterior restorative treatment in Class II cavities include good aesthetics, proper preparation width, well-established proximal contact, and proper occlusion. Class II cavity restoration using composite resin with the aid of a matrix is essential to prevent food impaction.

The restoration process begins with selecting and placing the matrix, applying etching for 10 seconds, curing it with a light cure, and applying bonding using a microbrush. The composite resin is then incrementally placed, starting with the formation of the proximal wall. The procedure continues with contouring, finishing, and polishing to achieve optimal results
