OBJECTIVES To adequately perform orthognathic surgery procedures, it is from basic interest to understand the morphologic changes caused by orthognathic surgery. Anthropometric analyses of standardized frontal view and profile photographs could help to investigate and understand such changes. STUDY DESIGN We present a pre- to postoperative evaluation of orthognathic surgery results based on a...

It is perceived that fuller lips are more attractive, and hence lip augmentation has become common in esthetic plastic surgery. Numerous materials have been used, including collagen, autologous adipocytes, and more recently Restylane; however, little data exist on what comprises esthetically beautiful lips. Photographs of 28 models from fashion magazines were scanned to obtain digital images. T...

statement of the problem: in the evolution of orthodontics, the changes in soft tissue, especially smile line attracts considerable attention. purpose: the present study was carried out to evaluate the correlation of the smile line with the vertical parameters of anterior part of face. materials and methods: forty-six iranian adults, aged between 18-25 years were selected. five quantitative and...

BACKGROUND The whistle deformity is one of the common sequelae of secondary cleft lip deformities. Santos reported using a crossed-denuded flap for primary cleft lip repair to prevent a vermilion notching. The authors modified this technique to correct the whistle deformity, calling their version the cross-muscle flap. METHODS From May 2005 to January 2011, 14 secondary unilateral cleft lip p...

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 ...

OBJECTIVE To evaluate whether mandibular setback surgery (MSS) for Class III patients would produce gradients of three-dimensional (3D) soft tissue changes in the vertical and transverse aspects. MATERIALS AND METHODS The samples consisted of 26 Class III patients treated with MSS using bilateral sagittal split ramus osteotomy. Lateral cephalograms and 3D facial scan images were taken before ...

STATEMENT OF PROBLEM In complete mouth reconstructive dentistry, the occlusal vertical dimension may be increased to provide adequate restorative space or to improve esthetics. The effect of increasing the occlusal vertical dimension on the smile is not well understood. PURPOSE The purpose of this study was to evaluate the effect of increasing the occlusal vertical dimension on the dimensions...

OBJECTIVES To evaluate the cephalometric features of subjects with incompetent lips, and to find the most discriminant variables for lip incompetence among the following: dental protrusion and proclination, antero-posterior and vertical skeletal relationships, and lip dimensions. METHODS This retrospective study was conducted at King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia, betw...

Background Lip lifting is a widely accepted and efficient surgical procedure for volumizing the upper lip to achieve more youthful appearance. A previous study by Hwang et al. identified lip-related ratios most preferred Koreans: height-to-width ratio (LTW) of 0.4, an upper-to-lower vermilion (ULR) 0.8, thickness-to-upper height (VUL) 0.5. The current investigated whether attractive favored Kor...

We present the first results from applying a recently proposed novel algorithm for the robust and reliable automatic extraction of lip feature points to an audio-video speech data corpus. This corpus comprises 10 native speakers uttering sequences that cover the range of phonemes and visemes in Australian English. The lip-tracking algorithm is based on stereo vision which has the advantage of m...
