- 2. INTRODUCTION • Excessive gingival display (EGD) or gummy smile is identified as displaying more than 2 mm of gingiva during maximum smiling. • The origins of EGD could be skeletal as in cases of vertical maxillary excess, muscular as in cases of short/hypertonic upper lips, or dentogingival abnormalities like in cases of altered passive eruption (APE) or a combination of these causes.
- 4. AIM - The study was carried out to compare the stability of gingival margin levels, pain levels, wound healing, and operating time after digitally guided ECL versus conventional ECL, in an attempt to shed light on the importance and convenience of digital dentistry in esthetic periodontal surgery
- 5. METHODOLOGY
- 6. • Gummy smile due to APE type 1B. • Age range of 20–40 years. • Systemically (medically) free. • Patients with thick gingival phenotype, and good compliance with the plaque control instructions • Smokers • Pregnant or lactating, • Teeth with compromised periodontium, • Using medications that affect periodontal wound healing or • Had periodontal surgery in the esthetic zone in the past 6 months.

The operating time needed to complete the surgery was recorded on a stopwatch from the time of the first incision till the completion of bone removal. 2.Pain Scores 3.Gingival margin stability (GMS) 4.The clinical features of periodontal wound healing were assessed 1 week, 3 months, and 6 months postoperatively using the following parameters:

- 18. CONCLUSION Within the limitations of this study, it can be concluded that: 1. Digitally assisted surgical ECL helps shorten the operating time and reduces the possibility of human errors during the measurements. This will be useful in helping practitioners (who might have a higher possibility for errors) to achieve better results. 2. Better results in terms of operating time were achieved by the digitally assisted ECL Group. 3. Similar results in terms of wound healing, patient satisfaction, and GMS were found in both groups.
