Restorative Technique for Class II Amalgam Preparations

Dentin desensitizer is placed on the prepared tooth structure per manufacturer instructions to reduce sensitivity.
Excess moisture is removed without desiccating the dentin to ensure optimal desensitizer placement.
The matrix's primary function is to enable proper restoration of anatomic contours and contact areas.
Qualities of a good matrix include rigidity, anatomic contour establishment, correct proximal contact relationships, prevention of gingival excess, convenient application, and easy removal.
The universal matrix system (Tofflemire Retainer) is designed by B.R. Tofflemire and is indicated when three surfaces (mesial, occlusal, distal) of a posterior tooth have been prepared.
The universal matrix is also commonly used for the two-.
The universal matrix system is used for restoring proper anatomic contours and contact areas in posterior teeth.
The placement technique for the universal (Tofflemire) and precontoured matrix systems is presented.
The precontoured matrix system is utilized to restore proper anatomic contours and contact areas in posterior teeth.
The precontoured matrix system is convenient for clinicians due to its pre-shaped design.
Proper placement of both universal and precontoured matrices is essential for successful restoration of posterior teeth.
The matrix system is crucial for achieving optimal results in the restoration of posterior teeth.
