Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group A : Saddle contoured metal matrix

The prepared teeth received the Saddle contoured metal matrix. The saddle clip of matrix connect the band and secured around prepared cavity wall. The anatomical wedge placed into the gingival embrasure to maintain the height of gingival floor and ensure the optimal adaptation of the matrix band in the cervical region.

Group Type EXPERIMENTAL

Saddle contoured metal matrix, Pre-contoured self-adhesive matrix

Intervention Type DEVICE

Saddle contoured metal matrix placed with the small clipper. The -contoured self-adhesive matrix has self adhesive ability.

Group B:pre-contoured self-adhesive matrix

Teeth received the Pre-contoured self adhesive matrix with anatomical wedges. The adhesive end of band closed around the prepared cavity.

Group Type ACTIVE_COMPARATOR

Saddle contoured metal matrix, Pre-contoured self-adhesive matrix

Intervention Type DEVICE

Saddle contoured metal matrix placed with the small clipper. The -contoured self-adhesive matrix has self adhesive ability.
