简要总结
Compare pain response following microsurgical conventional flap approach using Piezosurgery versus flapless approach for esthetic crown lengthening in management of patients with short clinical crowns in the upper anterior region.
详细描述
The conventional approach: Anesthesia will be given followed by bone sounding using William graduated periodontal probe and measuring the pocket depth (using magnification loupes and microsurgical blades)
- Marking the bleeding points
- An internal bevel incision is made followed afterwards by a sulcular incision.
- The gingival collar is eliminated.
- Elevation of the flap is proceeded to allow access for osteoplasty using piezo surgery and an apical position of the bone 2-3mm beyond CEJ.
- Mattress suture (6.0) is made
The intervention approach:
Surgery is done the same as in the conventional approach but without opening a flap, gaining access via a tunneling instrument and piezo tips for osteoplasty
