Occlusal Wear Of Bioflx Crowns Compared To Zirconia Crowns On Primary Molars

"Crown Selection \& Tooth Preparation~Measure the mesiodistal width using calipers to select an appropriately sized crown.~If a mesial or distal wall is missing, use the contralateral tooth for size selection.~Choose the crown that closely matches the measured mesiodistal width. Select the smallest crown that preserves proximal contacts using a trial-and-error approach.~if crimping is necessary use Howe's pliers.~Tooth Preparation Perform 1-1.5 mm occlusal reduction using a tapered diamond bur. Reduce proximal areas by approximately 0.5 mm to clear the contact area.~Crown Placement \& Cementation Ensure a snug fit of the selected crown. Apply a thin layer of glass ionomer cement inside the crown. Seat the crown firmly using finger pressure. Have the child bite down gently to ensure proper seating.~Final Adjustments \& Cleanup Remove excess cement with floss or an explorer. Verify the crown's fit, occlusion, and stability."

Select the smallest crown that preserves proximal contacts.~Tooth Preparation~Reduce the occlusal surface by 1.5-2 mm using a tapered diamond bur. Reduce interproximal areas by 1-1.5 mm, ensuring a feather-edge finish. Perform a 1-2 mm subgingival preparation using a tapered fissure bur.~Crown Placement \& Passive Fit Check~Place the selected crown and check for passive fit.~Cementation of the Crown~Apply a thin layer of glass ionomer cement inside the crown. Seat the crown with passive finger pressure. Have the child bite down gently to ensure proper seating.~Final Adjustments \& Cleanup~Remove excess cement using floss or an explorer. Verify fit, occlusion, and stability"
