Clinical Evaluation

The clinical evaluation of the patients before treatment.

The presence of oligodontia is associated with alterations of maxillary and
mandibular growth⁵^,⁷^,⁹ and several dentoalveolar alterations ⁸^,¹⁰^,¹¹.
The missing teeth and the growth pattern influence the soft tissue profile.

The most prominent craniofacial alterations are

·	Maxillary hypoplasia mandibular hypoplasia and bimaxillary hypoplasia
·	Reduced vertical and transversal dimension of alveolar process
·	Receding mid-face
·	Decreased anterior facial height
·	Increased nasal-labial angle
·	Deep labiomental sulcus

The most prominent dentoalveolar alterations are

· Occlusal disturbances

1. Deep bite
2. Cross bite
3. Steep inclination of incisors
4. Unusual abrasion

· Disturbances of eruption

1. Alteration of tooth position
2. Impaction
3. Over eruption

· Alterations of tooth morphology

1. Conical shape of existing teeth
2. Decreased size of existing teeth
