Crouzon syndrome is one of the frequent pathologies within craniosynostosis syndrome. Current progress in computers and biotechnologies allows improving surgical approach and forecasting final result of reconstruction as well. We present a case of successful surgical treatment of Crouzon syndrome, done by application of virtual planning allowing determining “monobloc” features, type of reconstruction and distraction protocol as well. A 20-year-old female had presented with craniofacial deformity. Clinical and radiological investigation revealed Crouzon syndrome. The “monobloc” creation, cranioplasty and internal distractors positioning, direction and schedule of advancement were done according to preoperative virtual planning data achieved by Materialise Mimics Research software. Nine months postoperative functional and esthetic result and radiological findings showed to be reasonable. That application of virtual simulation significantly allows to determine best direction of distraction and improves postoperative outcomes of surgical treatment of Crouzon syndrome.

Objective: (1) To establish cephalometric standards for the Turkish adult population, (2) to compare Turkish norms with the published standards of McNamara norms, and (3) to compare the assessment of craniofacial structure by extracranial and intracranial reference lines. Materials and Method: The main study sample consisted of 44 female and 29 male dental students aged between 19 and 29 years. All of the head films were taken in the natural head position, which was determined with 0.5-mm wire that was attached to a fluid level device to represent the true horizontal and a metal chain that was suspended in front of the cassette to check the true horizontal.

The most common abnormality in orthodontics is distal malocclusion. The patient will benefit more if is treated during active growth phase. Various types of functional appliances are used in order to control maxillary and mandibular growth. In this article we compared vertical changes in mandibular position as a result of 3 different distal malocclusion treatment methods. To this end, groups consisting of, 17 patients treated with dynamax appliance, 17 patients treated with Monoblock appliance, 16 patients treated with a Monoblock-Headgear combination were created. Research has shown that, treatment with removable functional appliances results in parallel downward positioning of mandible; treatment with semiremovable appliances results in backward and downward rotation of mandible and that the extraoral appliances are useless to control the lower facial height.
