Cephalometric analysis
Cephalometric analysis is the clinical application of cephalometry. It is analysis of the dental and skeletal relationships in the head.〔(Centre for Cancer Education, March 5, 2000 )〕 It is frequently used by dentists, orthodontists, and oral and maxillofacial surgeons as a treatment planning tool.〔(Cephalometric analysis as a tool for treatment planning and evaluation, ''European Journal of Orthodontics'' 1981 3(4):241-245 )〕
Two of the more popular methods of analysis used in orthodontology are the ''Steiner analysis'', named after Cecil C. Steiner, and the ''McNamara analysis'', named after James A. McNamara.〔(A comparative evaluation of Steiner's and McNamara's methods for determining the position of the bone bases, ''Minerva Stomatol.'' 1991 Jun;40(6):381-5 )〕 There are other methods as well, including the ''Ricketts analysis''.〔(Evaluating Ricketts' Cephalometric Analysis as Diagnostic Aid in Black Females, Center For the Study of Human Growth and Development April 5, 2008 )〕
==Cephalometric radiographs==
Cephalometric analysis depends on cephalometric radiography to study relationships between bony and soft tissue landmarks and can be used to diagnose facial growth abnormalities prior to treatment, in the middle of treatment to evaluate progress or at the conclusion of treatment to ascertain that the goals of treatment have been met.〔Predoctoral Orthodontic Laboratory Manual 2008, Department of Undergraduate Orthodontics, New Jersey Dental School〕
A Cephalometric radiograph is a radiograph of the head taken in a Cephalometer (Cephalostat) that is a head-holding device introduced in 1931 by Birdsall Holly Broadbent Sr. in USA〔US Patent #2032833 by Birdsall H. Broadbent http://www.google.com/patents/US2032833〕 and by H. Hofrath in Germany. The Cephalometer is used to obtain standardized and comparable craniofacial images on radiograghic films.
