Abstract

The purpose of ‘digital imaging’ in orthodontics is to display anatomical structure of a patient for proper diagnosis and treatment planning. Until now, imaging technology was limited to two dimensions. Some 3-dimensional (3D) imaging techniques have been developed but they are limited by the amount of information they can display and by their static nature. The development of an interactive 3-Dimensional digital model of a patient’s anatomy would greatly improve our ability to determine different treatment options, to monitor changes over time, to predict and display final treatment results, and to measure treatment outcome more accurately. But the main disadvantage is that it cannot be articulated. Digital orthodontic models are as reliable as traditional stone models and probably will become the standard for orthodontic clinical use. Now a days Study model, Digital radiograph and digital photography plays vital role in diagnosis and treatment planning of orthodonticpatient. This article describes about indication,advantages, disadvantage and the procedure of digital model.

Abstract

Cleft defects are very common deformations in the head and neck region. This requires immediate intervention by specialists from birth. Counseling patient and family members from the initial period is vital. Treatment is done phase by phase. There have been various factors affecting prevalence of this defect. This article is a review of the epidemiology of cleft defects, observed in different regions and in India.

Keywords

Abstract

Teeth play a fantastic role in the line of mammalian evolution. Apart from being covered in one of nature’s hardest substances so that it can take anything a million years of geology can throw at it, a tooth’s 3D shape is a phenomenally subtle food processing surface. Much like Charles Darwin found out about the beaks of finches, different types of teeth have an evolutionary history as well. Darwin found that the birds’ beaks were specially shaped depending on the type of food they ate. Short, sturdy beaks belonged to finches that needed to crack nuts to get nutrition, while long and pointy beaks were used to poke into the cracks of trees to find juicy insects to eat.

Some of the most noticeable changes in the evolution of the genus have been in the dentition and the jaws which support them. In general, living people have smaller teeth and less robust jaws than people living 25,000 years ago. Neanderthals, from perhaps 120,000 and becoming extinct in Europe after 30,000 years ago, had unusually large incisor and canine teeth, together with several other unique dental features. The oldest British hominin fossil teeth, at about 500,000 years ago, from the Boxgrove site in Sussex, were more significant still. In order to understand such differences, it is essential to see the teeth in the context of their use during life.
