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. Secondary objectives: Patient satisfaction: was assessed using visual analogue scale at 24 hours, 7 days and 14 days post operatively. (Zero is for minimum pain and ten is for maximum pain). Gingival margin stability: The position of gingival margin in relation to a reference point was evaluated immediately after surgery, 3 months and 6 months healing period .
