Orbitofacial anthropometrics have become an important tool used in reconstructive surgery. The authors attempt to evaluate the relation between orbital lateral canthal distance and the cephalometric characteristic of mandible in Iranian population.In a cross-sectional study, anthropometric parameters of face in 200 subjects (100 males and 100 females) with mean age of 34.39 ± 18.83 were evaluated by three-dimensional computed tomography imaging.In this study, there was not a significant difference in the age of sex groups (P = 0.183). Also, there was no significant difference in the left and right mandible angle in different sex groups (P = 0.25, P = 0.124, respectively). There were significant differences in the anterior mandible distance, inferior mandible angle distance (P = 0.0001) and lateral cantus distance of sex groups (P = 0.0001). There was a significant correlation between lateral contuse distance and left mandible angle (r = 0.226, P = 0.001), right mandible angle (r = 0.283, P = 0.00), mandible angle (r = -0.266, P = 0.00), anterior mandible angle distance (r = 0.655, P = 0.00), and inferior mandible angle distance (r = 0.582, P = 0.00).Here, we conclude that orbital lateral canthal distance can predict the cephalometric characteristic of mandible in Iranian population.

Aim: This study aimed to analyze the upper airway dimensions in adult patients with different anteroposterior (sagittal) skeletal malocclusions (class I, II, and III) using cone beam computed tomography (CBCT) imaging.
Materials And Methods: This retrospective cross-sectional study involved 90 CBCT records from adult subjects who were categorized into three skeletal groups based on their ANB values: Class I ( = 30), class II ( = 30), and class III ( = 30) and were evaluated. The following upper airway measurements were considered: oropharyngeal airway volume, hypopharyngeal airway volume, pharyngeal airway volume, oropharyngeal airway length, hypopharyngeal airway length, pharyngeal airway length, the most constricted site of the pharyngeal airway, and the most constricted cross-sectional area (MIN-CSA) of the pharyngeal airway.
Revisiting Visual Criteria of the Ideal Neck in the Young Caucasian Female.

Plastic surgeon in private practice, Dallas, TX, USA.
Background: The description of the aesthetically ideal neck was first described by Ellenbogen and colleagues in 1980. Since then, visual and aesthetic goals of patients have evolved as new surgical techniques have been described.
Objectives: Our study aims to provide current objective data regarding the aesthetically ideal neck in a young Caucasian female and evaluate Ellenbogen's original criteria for a youthful neck in this specific population.
Aim: Fixed retention is the method of choice for permanent stabilization of the treatment outcome. In recent years, CAD/CAM techniques have been developed to produce retainers with high precision and tension-free fit. The aim of this retrospective study was to evaluate the suitability of a semi-industrial retainer manufacturing process (office-based construction, external laboratory manufacturing) in terms of positioning accuracy and post-treatment changes.

: The main aim of this paper was to perform the morphological assessment of children's mandibles of different etiology of dys-functions within the temporomandibular joint, from isolated idiopathic ankylosis to craniofacial malformations co-existing with genetic disorders. : The investigations encompassed seven patients at the age of 0-3. Measurements were conducted on the basis of data obtained from computed tomography.

Department of Agr. Machinery and Technology Engineering, Akdeniz University, Antalya, Turkey.
Background: Examining stress distributions in abutment teeth with periapical lesions is essential for understanding their biomechanical impact on dental structures and tissues. This study uses finite element analysis (FEA) to evaluate these stress patterns under occlusal forces, aiming to enhance treatment strategies and prosthetic designs.
Methods: Three FEA models were created: a healthy mandibular premolar (Model 1), a premolar with a single crown and a lesion repaired using a fiber-post (Model 2), and 3) a premolar with a lesion repaired using fiber-post to support a four-member bridge (Model 3).
