offer precision, faster wound healing, less discomfort,
and superior aesthetics. To attain satisfactory results,
cases suggested for crown lengthening in the aesthetic
zone require unique considerations. The employment of
appropriate diagnostic methods, surgical and

certainity and achievement. This review article will go
