Anterior Zirconia vs. Resin Strip Crowns

"Technique:~I.Select shade of resin-based composite II.Rubber dam isolation III.Select primary incisor celluloid crown form with mesiodistal width similar to the tooth to be restored and trim the selected crown form to fit.~IV.Remove decay with slow speed round bur. Perform pulp therapy, if indicated. V.Reduce incisal edge by 1.5 mm VI.Reduce interproximal surfaces by 0.5 to 1.0 mm with feather edge at gingival margin. The interproximal walls should be approximately parallel.~VII.Reduce buccal surface by 1.0 mm and lingual surface by 0.5 mm with feather edge at gingival margins.~VIII. Round line angles IX.Etch for 15 to 20 seconds, rinse and air dry X. Apply bond and polymerise XI. Fill crown form to 2/3 full with composite resin and seat onto the tooth. Remove excess material with hand instrument. Polymerise.~XII. Remove celluloid crown form with scaler XIII. Finish and polish"

I.Choose appropriately sized crown based on tooth's dimension; evaluate occlusion. II.Rubber dam isolation. III.Remove decay, perform pulp therapy if indicated. IV.Prep mesial half of incisal edge to complete thickness of 001 donut bur. V.Prep and blend distal half of incisal edge to create uniform incisal reduction. VI. Create chamfer margin at gum line at least half the thickness of bur tip. VII. Taper incisal half lingually to create a thin incisal edge. VIII. Remove cingulum and 0.75-1.25mm of lingual enamel; blend together forming smooth, slightly concave surface extending to tissue. IX. Thin incisal half. X.With 004 flame bur, remove chamfer margin at tissue level. Keep bur parallel to long axis of tooth. Remove chamfer in incremental steps, XI. Extend tip of bur full 2mm subgingivally. While hugging bur axially along root surface, make 3 circumferential passes. XII.Clean tooth and control bleeding. XIII.Cement crown with pure glass ionomer cement
