Study Overview
Brief Summary
The objective of the present study was to evaluate the effectiveness of surgical esthetic crown lengthening using digitally assisted 3D printed surgical stents in management of excessive gingival display due to altered passive eruption.
Detailed Description
The objective of the present study was to evaluate the effectiveness of surgical esthetic crown lengthening using digitally assisted 3D printed surgical stents in management of excessive gingival display due to altered passive eruption.
Primary objectives:
Wound healing Score: the clinical features of periodontal wound healing were measured according to Hagenaars et al using the following parameters: swelling of the soft tissue , color of the gingiva, probing pocket depth, bleeding index, plaque index, clinical attachment level. These signs were assessed at 1 week, 3 months and 6 months post-operative.
Operating time: the time needed to complete each procedure was calculated in minutes by using a stopwatch from the time of the first incision till the completion of bone removal.

Arms & Interventions
Control Group
Eight patients indicated for ECL were managed by conventional crown lengthening.
Intervention: Conventional Esthetic crown lengthening (Procedure)
Test Group
Eight patients indicated for ECL were treated using digitally assisted crown lengthening utilizing 3D printed surgical stents.
Intervention: Computer guided Esthetic crown lengthening (Procedure)
Outcomes
Primary Outcomes
Wound Healing
Time Frame: Change in soft tissue features from 1 week to 6 months post operative
the clinical features of periodontal wound healing were measured according to Hagenaars et al using the following parameters: color of the gingiva (C) (a score of 0-2) 0=no redness, 1=moderate redness, 2=pronounced redness
Operating time
Time Frame: During surgery
the time needed to complete each procedure from the first incision till the completion of bone removal
Secondary Outcomes
- Patient satisfaction(1 day - 1 week - 2 weeks post operative)
- Gingival margin stability(Baseline - 3 months post operative - 6 months post operative)
