  3. 3. Mohammed Almuzian, 2013, University of Glasgow Page 3 Maxillary midline diastema and frenum Prevalence • 6% in general • Male more than female • Black more than white • Young more than adult Causes of diastema 1. Normal development in the deciduous dentition 2. Ugly duckling stage before the eruption of the permanent canines 3. Abnormal frenal attachments 4. Microdontia (peg-lateral incisors) 5. Presence of a supernumerary 6. Abnormal shape or crown-root angulation of the centrals 7. Congenitally missing teeth 8. Abnormal pressure habits (tongue thrust, digit sucking, 9. Trauma, leading to tooth loss in the incisor region 10.Hereditary & Racial predisposition, Negros 11.Pathological migration of the anterior maxilla teeth (rarely) 12.Iatrogenic during RME Diagnostic feature for a prominent labial fraenum as a reason for 1. It can often be seen between the maxillary central incisors on direct visualization; 2. Blanching in the region of the frenum can occur when tension is applied by lifting the upper lip;
  4. 4. Mohammed Almuzian, 2013, University of Glasgow Page 4 3. A spade-shaped or notched intermaxillary segment can be visible on radiographic examination. 4. Diastema with crowding elsewhere Management A. It depends primarily upon the removal of the underlying cause. B. in the deciduous dentition , no treatment C. in mixed dentition just reassure D. in permanent dentition 1. Aesthetic build-up of the centrals 2. Active orthodontic treatment to close a diastema is usually carried out in the permanent dentition. Using: • URA • FA 3. Long-term retention is usually mandatory. For this reason, particularly for a minor diastema, persuading the patient that it is a feature of individuality that does not require closing can be advantageous. 4. Adjunctive procedure like frenectomy Edward 1977 mentioned the opposite. Retention and relapse 50% risk of relapse with high incidence in patient with:  More than 2mm diastemas  Family tendency
