Having proper contact in multiple cl II restorations was considered a nightmare for clinicians. The most challenging in these cases is to restore proper, healthy, and functional contacts to prevent future food stagnation. Accordingly, the aim of this case is to simplify the procedure of restoring multiple proximal cavities.

Initial situation, a male patient presented to the clinic with multiple proximal caries. The initial photograph demonstrated that the patient is suffering from cavitation and food impaction between teeth 14 and 15.

Complete cleaning and cavity design were achieved on both teeth.

For tooth 15, a transparent sectional matrix was used for the distal wall to restore a correct proximal contour without distortion. In addition, placing a ring was considered important for ensuring an intimate adaptation of the matrix with the tooth surface and to gain more separation. For mesial proximal wall, a metal sectional matrix was secured by a wedge.

After finishing the restoration for the tooth 15, the restoration of the tooth 14 was started by placing a sectional matrix secured with a wedge. To restore a proper proximal contour, placing a ring for separation and adaptation of the band on the tooth surface were considered the key of the treatment plan.

After completing the restoration for the tooth 14, the finishing and polishing procedure is achieved.
The proper proximal contour for both premolars can be clearly seen.

Restoring multiple proximal cavities can be challenging. To simplify the working flow and to get the ideal results, a good diagnosis and a preoperative treatment plan are crucial.
