• 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 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.
