It is said that Cephalometrics is the language in which poetry of orthodontic diagnosis and treatment planning is written. Cephalometrics is useful in determination of morphology and growth, diagnosis of anomalies, forecasting future relationships, planning appropriate biomechanics, evaluating pre and post treatment changes/efficacy of treatment mechanics, and studying relapse. It is the single most important research tool in the hands of orthodontists, physical anthropologists and growth science biologists. Cephalometric analyses provide information about size and shape of the craniofacial components and their relative position and orientation. Cephalogram’s mainstay is that it is the only practical quantitative method that permits the investigation and evaluation of the spatial relationships between cranial and dental structures. This book provides the clinician with background information on the evolution of cephalometric radiography in Orthodontics, an overview of the various hard tissue cephalometric analyses and studies done on Indian population, recent advances in the cephalometric radiography.
