Case Details
Interproximal caries is the most common type of dental pathology and therefore interproximal fillings in the posterior area are the most common restorative procedures. Restoring adequate cervical contour and tight interproximal contacts are of utmost importance for long term stability of such restorations. Open contacts and cervical overhangs lead to development of secondary caries and periodontal pocket.
Modern sectional matrices, interproximal wedges and ring systems like the Garrison sectional matrix system make the procedures more predictable and allow dental practitioners to restore such cavities easily.
The presented case is removal of the interproximal caries with deep cervical margin and wide buccal and palatal extensions. After the cavity preparation and isolation with the rubber dam, Garrison matrix with extension, Blue (small) wedge and Wide Prep (green) ring were placed. The wide extensions of the ring allow to restore adequate buccal and palatal contours of the tooth. The sectional matrix is easily shaped to restore proper anatomy and tight contacts. The rest of the cavity is filled with respect of the simplified tooth anatomy. Rough polishing and contouring were done under the rubber dam isolation. After the removal of the rubber dam the procedure ends with fine polishing and occlusal corrections.
