Relationship between Changes of Nasal Length and Upper Lip Height during Smile

Relationship between Changes of Nasal Length and Upper Lip Height during Smile

Depressor septi nasi is an important muscle in the nose and upper lip dynamics.1-4 Hypertrophy of this muscle leads to a deformity during smiling presented by depression of nasal tip, shortening of upper lip, and a horizontal crease in upper lip.4 Rhino-gingivolabial syndrome was defined as depression of nasal tip, shortening of upper lip, and gingival show. This syndrome was attributed to the ...

Evaluation of Upper lip length in vertical growth pattern individuals with and without gummy smile

Abstract Background and Aim :The most esthetic smile is when the entire length of the crown of the tooth and 2 mm of the gums are visable. Most of it is not aesthetically pleasing and is called gummy smile or gingival smile.Upper lip length is one of the factors influencing the gummy smile. The aim of the present study was to investigate the upper lip length in patients with vertical growth pat...

Relationship between Hyperactivity of Depressor Septi Nasi Muscle and Changes of Alar Base and Flaring during Smile

BACKGROUND Hyperactivity of depressor septi nasi muscle leads to smiling deformity and nasal tip depression. Lateral fascicles of this muscle help in widening the nostrils. The purpose of this study was to evaluate the relationship between the nasal length changes and the alar base and the alar flaring changes during smile. METHODS Standard photographs are performed in the face and lat...

[Anthropometrical measurements of the height of the upper lip and length of the philtrum].

BACKGROUND indirect anthropometrical measurements of the height of the upper lip and length of the philtrum. AIM to describe the measurements of the height of the upper lip and length of the philtrum, extracted from video x-rays, in children with mixed dentition, relating these measurements to facial typology--medium and long-, to occlusion--Angle's class I and II--and to the rest position of...

Evaluation of Relationship between Smile Line and Age

Smile line is one of the most important element of the smile esthetics. In an attractive smile, the maxillary anterior incisal curve is parallel to the lower lip. With the changes in face, lips and teeth muscles, which are caused by aging, this element (smile line) also changes. Aging causes smile line to move from its parallel position and in complete smile, formulate different shapes relative...
