Preparation: Administration of 2% lidocaine local anesthesia with epinephrine; caries removal; 1-1.5 mm incisal reduction; 1 mm mesial/distal contact breaking using diamond burs; minimal labial/palatal reduction; rounding of sharp line angles. Seating \& Cementation: Selection of appropriate Bioflx crown size via mesiodistal caliper measurement; crown try-in; cavity sealing and final cementation using self-curing glass ionomer cement (IMICRYL Nova); excess cement removal with explorer and dental floss.

Preparation: Local anesthesia administration; caries removal; shade selection; incisal and proximal reduction. Matrix \& Bonding: Celluloid strip crown form selected, trimmed to length, verified for cervical adaptation, and vented at the incisal edge. Enamel etched with 37% phosphoric acid (CharmEtch) for 15 seconds, rinsed, and dried. Universal bonding agent (All-Bond Universal) applied and light-cured for 15 seconds. Placement \& Finishing: Crown form filled with shade-matched composite resin (Beautifil), seated firmly on the tooth, excess material removed, and light-cured. Celluloid form stripped off using an excavator; final polishing performed.
