Advantages of Composite Direct and New Semi-Direct Techniques - Morphological Correction and Improving Esthetics of Anterior Diastema

Diastemata is a common esthetic problem in mixed and early permanent dentitions at the time of eruption of the maxillary incisors. Different materials such as composite resin and ceramics are commonly used with indirect tech- niques, yet the recent major improvements in composite resin properties suggest a more conservative approach. Direct bonding in diastema closure cases allows clini- cal control in definition of the interproximal layer, even with multiple dental treatments. It is crucial to have an efficient and stable guide for the layering of each mate- rial. In the case of anterior multiple distemas, a semidi- rect technique may improve the precision of the resto- ration. Laboratory-fabricated composite layers, adapted with cyanoacrylate glue on the rigid silicone template, are bonded on the palatal surface of each tooth. Both techniques allow us to improve dental morphol- ogy and enhance the esthetics of a smile, using compos- ite restorations with a minimally invasive approach. It ensures that any future dental interventions can remain minimally invasive in their scope. The positive response of periodontal tissues confirm a perfect integration of the restorations. Morphological corrections with direct and semidirect techniques allow us to realize an intervention that would further improve esthetics while minimizing the biologic cost.
