CATEGORY 50 AUSTRALASIAN DENTIST XSL and Shofu Beautifil LS II packable composite, employing the snowplough technique due to the relatively small size of the defect. On the distal aspect, only the proximal wall was reconstructed in order to convert the Class II defect into a Class I configuration. Given the large size of the distal wall defect, the proximal wall was built in two increments – first from the buccal side and then from the lingual. This incremental approach was selected to minimize polymerization shrinkage stress. Once the walls were completed, the matrix bands were carefully removed. Notably, no excess composite flange or flash was observed, demonstrating the precision and sealing efficiency of the Garrison Quad Matrix system. bicarbonate powder with an air polisher unit (image 11). The rubber dam was removed, and high points were checked using 40-micron paper, followed by 8-micron foil in static occlusion. For dynamic occlusion, 200-micron paper was used, and adjustments were made to the cuspal slopes and non-functional cusps. Conclusion The quadrant restorative approach using the Garrison Quad Matrix System allowed precise reconstruction of proximal contacts, anatomical contour, and occlusal morphology in multiple adjacent Class II lesions. By first converting extensive MOD cavities into controlled Class I preparations through incremental wall build-up, polymerization shrinkage stress was minimized and tooth structure was preserved. The combination of Shofu Injectable XSL and Beautifil LS II packable composites, along with selective use of short-fibre composite, provided excellent marginal adaptation and structural reinforcement. This technique proved to be highly predictable, time-efficient, and minimally invasive, making it an ideal protocol for restoring multi-surface posterior defects while ensuring long-term functional stability and aesthetics. u CLINICAL Figure 8.

Due to large defect on distal side we decided to use short fiber composite followed Shofu Beautifil LS II packable as a final layer. All the layer placed incrementally in order to reduce shrinkage stress. Stains have added to make restoration look like more natural. The contours and embrasures were well established and finished using a Shofu Super Snap purple disk. The oxygen inhibition layer was removed using sodium Figure 14.
