简要总结
The goal of this randomized controlled clinical study is to compare Fully digital to wax-up/mock-up guided esthetic crown lengthening procedure in management of excessive gingival display caused by altered passive eruption type 1B
The main question it aims to answer is:
Does the fully digital guided gingivectomy approach able to introduce a more precise, accuracy and reliability technique with more patient satisfaction compared to the mock-up guided method?
详细描述
In today's world, the idea of smile and dental aesthetics extends beyond just the teeth. The fundamentals of a smile center on the interaction between the three key elements: the teeth, lips , and the gingiva.
Gummy smile (Excessive gingival display) is acknowledged by the American Academy of Periodontology (AAP) as a deformity and mucogingival problem that impacts the area surrounding the teeth
This condition may result from various etiological factors: short lip, hypermobile/hyperactive lip, short clinical crowns, dentoalveolar extrusion, altered passive eruption (APE), gingival hyperplasia, and vertical maxillary excess.
Altered passive eruption is described as "the gingival margin in adults is positioned incisal to the crown's cervical convexity and distanced from the tooth's cementoenamel junction."
Altered passive eruption defined as "the gingival margin in the adult is located incisal to the cervical convexity of the crown and removed from the cementoenamel junction of the tooth".
