Principles of selection of anterior artificial teeth depend on shape of face and bone, size of the teeth in relation to dimension of the teeth, sex and age of the patient. In addition to choosing anterior teeth according to color. It depends on age and sex, appearance and personality of the patient. Selecting anterior teeth depend on material may be porcelain, Ceramic, acrylic resin. Also arrangement of anterior teeth according to function and phonetics. Depend on less grinding teeth, position of anterior teeth and movement of the mandible as it has great importance in pronunciation.

The term “selection of teeth” is defined as the way to select, locate, tilt, rotate and placing the teeth in the denture in relation to the patient needs. After selection it must be arranged in the denture according to the protrusion of the mandible as the protrusion is classified into three classes as that each class need a special technique of arrangement as in class I the lower incisor should be opposed to the cingulum of the upper incisors in the other hand class III the upper incisor is in the cingulum of the lower incisor but in class II the icisal edge of the lower incisor I free of contact to any other teeth. Some complications may face the dentist in stabilizing the artificial teeth which is resorption of the alveolar ridge and the changes of the maxillo-mandibular relationship and restoring normal appearance of the patient but the most important thing is the selection because it gives the artificial teeth the appearance of the natural teeth. According to any professional dentist selection of anterior artificial teeth depends on some considerations as shape, size, color, material, phonetics and function of anterior teeth.

Selection of anterior teeth depends upon shape of the teeth in relation to shape of the face as they follow the same characteristics as Shetty etal (1) states that “In 1915 Williams introduced the square, ovoid and tapering concept of choosing the form of the teeth for dentures. A square face deserved square teeth, an ovoid face deserved ovoid teeth and tapered face, the tapered teeth” these proves that there are four types of faces which are ovoid , tapered , square and tapered square face as in fig. 11.1. Another factor affecting the arrangement of anterior teeth depends on the types of the palatal arch as they are two shapes U, v and square types. The palatal arch is affected by age as bone resorption happens in older people these affect the arrangement of the teeth as it needs larger teeth to contribute the resorption of the alveolar ridge.
