Brief Summary

The growing interest of patients in esthetic procedures, as well as the development of less invasive protocols in dentistry, has promoted the development of treatment plans that include stability, harmony, and function in orofacial rehabilitation.

Poor esthetics interfere with an individual's personal, social, and professional relationships and is an individual consideration that varies according to the patient's age, time, region, and culture concerning what is considered beautiful.

Detailed Description

People are increasingly being inspired to get more corrective and cosmetic surgeries as an esthetic smile becomes a more fundamental component of what it means to be beautiful.

There are several variables that affect how appealing and esthetic a smile is Esthetic perception varies according to cultural, societal, environmental, and individual factors like experience and educational level Previous studies have shown that a smile with less gingival display (GD) is viewed as more beautiful, with dental professionals being more critical of gingival presentation than laypeople According to research by several authors, the ideal GD ranges from 1 to 3 mm While many factors influence how pleasant a smile is seen, excessive GD (EGD), sometimes referred to as a gummy smile, is regarded as a key factor in smile analysis and one of the main issues connected to an unsatisfactory dental smile.

To reduce the relapse associated with repositioning surgery and to provide a lasting treatment without the need for reapplication, as in the case of the toxin, a combined treatment using the toxin preoperatively was considered.

Arm && Interventions

Group	Intervention	Description
intervention group	botox prior to modified lip repostioning	botox injection prior to surgical intervention by 5 to 10 days A surgical marker was used to outline the boundaries of the surgical incision region. the height of the superior incision was measured as 15 mm within the vestibule. Superior and inferior incisions were made with a scalpel blade number 15 and linked bilaterally by two vertical incisions. A partial thickness dissection was used to remove the strip of the indicated mucosa, exposing the fascia of the connective tissue beneath. When necessary, all salivary glands and frenal attachments were removed. The surgical site was then properly closed using a periosteal simple interrupted suture was put in place prior to the continuous interlocking sutures. It was placed by commencing the needle 2 mm coronal to Per surgery site, 3 to 4 periosteal sutures were typically The new mucosal boundary to the gingiva was stabilized in its new place using this suture
