The specific aim of this study was to determine the differences between 6 anthropometric (taken from the surface) and cephalometric (taken from x-rays) measurements and 12 proportion indices formed by the measurements obtained from the face of 51 healthy Caucasoid young adult males and females. The z-score analysis revealed negligible differences in frequency of normal values, in surface measur...

Cephalometric analysis has an important role in dentistry and especially in orthodontics as a treatment planning tool to gauge the size and special relationships of the teeth, jaws and cranium. The first step of using such analyses is localizing some important landmarks known as cephalometric landmarks on craniofacial in x-ray image. The past decade has seen a growing interest in automating thi...

His famous dissertation, published in 1947, The Face in Profile. An Anthropological X-ray Investigation on Swedish Children and Conscripts, is an outstanding contribution. That monograph became the classic example for numerous scholars to follow so that, 25 years later, a second printing was necessary. research fellow and guest lecturer at Northwestern University in Chicago, Illinois. In 1958 h...

Objective – Technological improvement is usually followed by comparisons between conventional and new. Those who work with radiographic assessment, such as cephalometric analysis for orthodontic diagnosis, have been living a new challenging and learning phase since the introduction of digital images. It is possible to obtain reproducible and clear images with digital radiography, but radiograph...

OBJECTIVE The efficacy of mandibular advancement devices (MADs) in the treatment of obstructive sleep apnea (OSA) ranges between 42% and 65%. However, it is still unclear which predictive factors can be used to select suitable patients for MAD treatment. This study aimed to systematically review the literature on the predictive value of cephalometric analysis for MAD treatment outcomes in adult...

Background. Rocabado’s hyoid triangle is the only cephalometric parameter that can assess the effects of orthodontic treatment on tongue posture. Aim. To evaluate the restoration of tongue posture and function by conducting a cephalometric assessment of the hyoid triangle before and after rapid maxillary expansion. Methods. Sixtyfour healthy patients aged 6-11 years with skeletal class II maloc...

PURPOSE This study was performed to evaluate the reliability of the identification of anatomical landmarks in panoramic and lateral cephalometric radiographs on a standard medical grade picture archiving communication system (PACS) monitor and a tablet computer (iPad 5). MATERIALS AND METHODS A total of 1000 radiographs, including 500 panoramic and 500 lateral cephalometric radiographs, were ...

In this study we examined anteroposterior cephalometric changes in children enrolled in a randomized controlled trial of early treatment for Class II malocclusion. Children, aged 9.6 +/- 0.8 years at the start of study, were randomly assigned to control (n = 81), bionator (n = 78), and headgear/biteplane (n = 90) treatments. Cephalograms were obtained initially, after Class I molars were obtain...

Maxillo-mandibular advancement MMA is considered an efficacious treatment for patients affected by severe obstructive sleep apnoea syndrome (OSAS). Even though OSAS improvement is the main goal of MMA, excessive maxillo-mandibular protrusion should be avoided to guarantee pleasant postoperative facial aesthetics. In order to attain such a result, the amount of MMA should be planned preoperative...
