Altered Passive Eruption of Teeth, Guided Surgery, Gummy Smile
Conditions
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. 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 .

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Wound Healing | 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 | During surgery | the time needed to complete each procedure from the first incision till the completion of bone removal |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient satisfaction | 1 day - 1 week - 2 weeks post operative | will be assessed using numerical visual analogue scale (scale of zero - no pain to ten- maximum pain) |
| Gingival margin stability | Baseline - 3 months post operative - 6 months post operative | The position of gingival margin in reference to an index is measured from the incisal edge to the free gingival margin |
