Various procedures and techniques have been devised in an attempt to generate tighter and more anatomic proximal contacts with class II composite restorations. The investigators study focuses on using Saddle contoured metal matrix and pre-contoured self-adhesive matrix .Moreover, the investigators have attempted to study proximal tightness and proximal contours of composite restoration as separate variables.
A total of 60 posterior teeth with proximal cavity to be assigned on alternate basis in two equal groups. Group A teeth received the Saddle contoured metal matrix and group B pre-contoured self-adhesive matrix after cavity preparation. All teeth to be restored with Nano hybrid composite restorative material. Outcome of proximal contours and contact tightness is determined by a blinded assessor just after the restoration.

RECRUITINGproximal contacts tightness
The tightness of the proximal contact area resulting from Saddle contoured metal matrix and pre-contoured self-adhesive matrix . It was measured using a nine inch long nylon dental floss (Oral-B, USA).
Time frame: immediately after procedure
Proximal contours and overhangs
To be examined clinically with an explorer and mouth mirror and then on the radiograph by the blinded co investigator.
Time frame: immediately after procedure
