Clinical Trial Summary

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.

Intervention

Procedure:
• Test group
The surgery will be done with the use of 4x magnification loop, the knives are micro blades and micro-sutures 7//0 used with the microsurgical instruments kit
• Control group
esthetic crown lengthening with conventional approach with an internal bevel incision, following CEJ anatomy, this will be followed by an intra-sulcular incision, removal of the strip of outlined marginal gingiva and elevation of a mucoperiosteal ?ap to the level of the alveolar bone crest.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mid-buccal gingival margin level	periodontal probe with William's graduation will be used to measure the distance from the CEJ to the gingival margin at the mid-buccal surface	6 months
Secondary	Pink Esthetic Score (PES)	The PES is based on seven variables: mesial papilla, distal papilla, soft-tissue level, soft tissue contour, alveolar process deficiency, soft-tissue color and texture. Each variable shall be assessed with a 2-1-0 score, with 2 being the best and 0 being the poorest score. The mesial and distal papilla will be evaluated for completeness, incompleteness or absence	6 months
Secondary	Post-Surgical swelling	will be evaluated post-surgically with Verbal Rating Scale with words ranging from (absent-slight-moderate-intense) Absent (no swelling), Slight (intraoral swelling at the operated area), Moderate (moderate intraoral swelling at the operated area) and Intense (intensive extra oral swelling extending beyond the operated area).	7days
Secondary	Post-Surgical Patient Satisfaction: 3-item questionnaire	A 3-item questionnaire is asked and the patients shall use a 7-point answer scale	6 months
