简要总结
the study compare gingival margin stability following conventional approach versus microsurgical approach of esthetic crown lengthening in management of patients with short clinical crowns in the upper anterior region.In management of patients with short clinical crowns in the upper anterior region, there is no difference in gingival margin stability between conventional and microsurgical approaches of esthetic crown lengthening.
