Objective: To determine if 3D shape correspondence can accurately quantify mandibularasymmetry in surgical patients. Methods: Pretreatment cone-Beam CT scans were acquiredof twenty orthognathic surgery patients with different degrees and types of facial asymmetry.The maxillofacial hard tissues were segmented and mirroring was performed for virtualsurgical planning using the Cran...

Aim: The aim of this study was to evaluate skeleto-dental abnormalities in 9-11-year-old school children, Tehran, Iran. Materials and Methods: In population-based cross-sectional descriptive study, a random cluster sampling done among 19 districts. A total 1,429 socioeconomically ethnically diverse Iranian schoolchildren, aged 9-11 years were studied. brief questionnaire including background in...

OBJECTIVE The aim of the study is to detect gender-wise difference in the skeletal asymmetry in the esthetically pleasing faces. MATERIALS AND METHODS a cross sectional study was conducted on 25 females and 25 males of age 18 -25 years using the posterior-anterior cephalograms. The selected part of grummon's frontal analysis for analyzing the vertical skeletal asymmetries, mandibular morpholo...

Introduction: Osteoma is a benign neoplasm resulting from the continuous formation of cortical or cancellous bone. Osteomas of the maxillofacial region mostly occur in the mandible. However, rarely osteomas seen in the mandibular condyle. Case Report: We present a case of a 33-year-old male patient reported with chief complaints of malocclusion, facial asymmetry, difficulty in chewing and devia...

This prospective cross-sectional, case-controlled morphometric study investigated three-dimensional facial morphological variation among and between 8- and 12-year-old children [40 with a unilateral cleft lip and palate (UCLP), 23 with a unilateral cleft lip and alveolus (UCLA), 19 with a bilateral cleft lip and palate (BCLP), and 21 with an isolated cleft palate (ICP)]. Eighty gender- and age-...

Management of significant facial asymmetry presents a challenge due to the geometric complexity of the bony and other facial structures. Manual model surgery is an essential part of treatment planning but it can be complicated, time-consuming and may contain potential errors. Computer-aided surgery has revolutionized the correction of maxillofacial deformities. The aim of this study was to repo...

AIM The purpose of this case report is to present the esthetic and functional rehabilitation of the teeth in a 20-year-old patient with amelogenesis imperfecta (AI), facial asymmetry due to functional mandibular shift, and unilateral posterior crossbite. BACKGROUND AI is a group of hereditary defects of enamel unassociated with any other generalized defects. AI results in poor development or ...

A reliable and accurate biometric identification system must be able to distinguish individuals even in situations where their biometric signatures are very similar. However, the strong similarity in the facial appearance of twins has complicated facial feature based recognition and has even compromised commercial face recognition systems. This paper addresses the above problem and proposes two...

The objective of this study was two-fold: (1) to explore the suitability of a novel modified Procrustes fit method to adjust data for head motion during instructed facial movements, and (2) to compare the adjusted data among repaired unilateral (n = 4) and bilateral (n = 5) cleft lip and palate patients and noncleft control subjects (n = 50). Using a video-based tracking system, three-dimension...
