Summary

Class II caries affects proximal surfaces of premolars and maintain their anatomical proximal contact of tooth, is important to avoid food impaction in the interdental area for protection of periodontium and occurrence of secondary carious lesion.Different types of Matrix band system are used to restore tooth cavities with missing proximal walls, including flat or pre-contoured bands, retainer-fixed circumferential systems, and sectional matrices, and either metal or plastic matrices which produces good contours and contacts for use with amalgam and can also be employed for insertion of composite resin.This study aimed at assessing the influence of different matricing techniques :either sectional matrix or circumferential matrix and the influence of operator experience on reproduction of optimum proximal contacts for posterior proximal resin composite restorations.

Conditions

  • Tooth Decay

Interventions

DEVICE

Sectional matrix

The sectional matrix is the best way to achieve a strong contact point in Class II restorations with composite resin in the posterior dental sector. The pre-wedging is essential to get a separation between teeth which avoid the matrix deformation during its insertion

DEVICE

Circumferential matrix

Circumferential matrix (thickness 0.038mm) ,the band encircle the tooth and secured by retainer on the buccal and lingual aspect
