Background: In forensics, sex estimation is an important step in identification process which can be seen from gonial angle. The purpose of this study was to identify sexual dimorphism angle based on the difference external factors such as diet and environment children, assess their capacity a estimator. Study design: present consists 104 subjects (51 males 53 females) between 7 12 years age we...

objectives: accurate localization of the inferior alveolar canal (iac) is extremely important in some dental treatments. anatomical variation of the canal means that it can be difficult to locate. the purpose of this study was to assess the relationship of the gonial angle (ga) size and iac position using cone beam computed tomography (cbct). materials and methods: in this in vitro study, 61 dr...

The effect of the Eureka Spring (ES) appliance was investigated on 37 consecutively treated, noncompliant patients with bilateral Class II malocclusions. Lateral cephalographs were taken at the start of orthodontic treatment (T1), at insertion of the ES (T2), and at removal of the ES (T3). The average treatment interval between T2 and T3 was four months. The Class II correction occurred almost ...

The purpose of this study was to investigate the outcome of early interceptive treatment of primary anterior crossbites with posterior occlusal acrylic resin blocks in combination with a 2 × 4 appliance, and to examine the differences in craniofacial morphology between the stable and relapse groups. Lateral cephalograms of 46 subjects (17 males and 29 females; average mean age 4 years 2 months ...

The aim of this article is to present intra- and extra-oral and cephalometric findings of three patients with a rare disease: the pycnodysostosis. Two cases had skeletal Class III malocclusion due to maxillary retrognathia and one had bimaxillary retrusion with Class I relationship. Total circular crossbite, increased gonial angle and vertical facial proportions, deep-narrow palates and retrude...

Pycnodysostosis (PDO) is a rare genetic disorder characterized by cathepsin K deficiency which plays an important role in bone metabolism. Among clinical features of this disease which are mainly caused by altered bone remodeling are craniofacial abnormalities such as hypoplastic maxilla and obtuse gonial angle which consequently lead to respiratory insufficiency in forms of pharyngeal narrowin...

Background: The purpose of this study was to investigate whether there is a role the low gonial angle on marginal bone resorption around implants placed in posterior mandible. Methods: This retrospective study, including 20 patients with 46 followed 36 months were inserted toothless area. Patients without systemic disease included study. measured panoramic x-ray; more than 1250were classified a...

BACKGROUND In Asian countries, many patients with a prominent mandibular angle desire its correction, because they consider it to be an unappealing feature. Reduction mandibuloplasty has been frequently performed through the intraoral approach, but an invisible mandibular angle forces the surgeon to perform blind ostectomy. In addition, the limited mobility of the oscillating saw leads to semi-...

This case report describes the treatment of a severe anterior and lateral open bite combined with multiple congenitally missing teeth. A 10-year-old girl presented with an open gonial angle, absence of lip sealing, and soft tissue pogonion retrusion. She had an open bite of 8.5 mm, agenesis of the upper right and left lateral incisors and the upper left first premolar, and transverse maxillary ...
