Patient-customized Site Specific Crown Lengthening

Abstract

Short clinical crowns result in poor retention form and thereby leads to improper tooth preparation and ultimately failure of restoration. The purpose of this case report was performing patient customized site specific surgical crown lengthening of grossly decayed tooth structure in left mandibular 2nd premolar area. The tooth was root canal treated with width of keratinized gingiva about 2mm on buccal side, with fibrotic gingival enlargement on interdental area and lingually. Apically displaced flap on buccal side with osseous resection of 3mm and undisplaced flap on interdental and lingual side with osseous resection of 3mm was done. Optimal clinical crown length was achieved and was maintained at 3months and 6 months follow up.
