Objectives: This study aimed to establish cephalometric norms for an Omani population of Arab descent and to compare these with established cephalometric values for Caucasians. Methods: This cross-sectional studywas conducted at the Military Dental Centre and Oman Dental College in Muscat, Oman, between May 2014 and October 2016. A total of 150 Omani patients between 20–29 years old seeking orthodontic treatment were included. All participants had a symmetrical face, class I molar and canine relationships, proper intercuspation, a normal overjet/overbite (<3 mm) and mild spacing/crowding of

Introduction: Open bite malocclusion is one of the most difficult dentofacial deformities to treat. Although this type of malocclusion can occur unilaterally or bilaterally in the buccal segments. It is mostly seen in the anterior segment where there is no incisal contact and vertical overlap of the lower incisors by the uppers.

Abstract:

Angle Class I malocclusion with bimaxillary protrusion is characterized by severe buccal tipping of incisors, which causes upper and lower lip protrusion. First premolars extraction is recommended to reduce facial convexity as a result of anterior teeth retraction, which keeps canines and first molars in key to occlusion. In order to yield orthodontic results that are compatible with ideal esthetic and cephalometric outcomes, the space closure phase needs to be carried out with overbite and incisors torque control. The majority of cases also requires maximum anchorage of posterior teeth. This

Abstract:

Orthodontic treatments can have an impact on the soft tissues and more particularly on the cutaneous profile. The aim of this work was to evaluate profile changes following orthodontic treatment. Material and methods: This study concerned 90 patients randomly selected in the orthodontic department of Monastir (Tunisia). Profile headfilms at the start and at the end of orthodontic treatment were compared using, as reference lines, the SN-7° plane and the orthogonal to SN-7° plane going through the S-point (POSN- 7°). The Student test was applied to evaluate the variations in the cephalometric m

Abstract:

The Eastman Standard values for cephalometry were first described almost 40 years ago and their derivation is not clear. The present study examines the rationale for the Standard and considers the way it was originally described. Based on a sample of 30 cases of Class I occlusions with normally related skeletal bases the mean incisor angulations were found to be exactly on the Eastman Standard, which, therefore, still remains appropriate as a basis of assessment and treatment planning in orthodontics.
