During this procedure, the cavity must be dried at regular intervals in order to be able to effectively distinguish between residual filling material and tooth substance as part of minimally invasive therapy.
Once caries excavation has been completed, a matrix and wedge are inserted into the interdental space to prevent excess filling material and to shape the restoration anatomically. Etching of the cavity using phosphoric acid is followed by the application of primer and bonding layer, which is cured for 30 seconds using an LED light.
The cavity bottom is sealed with a flow able material that helps to increase adhesion to the cavity walls and reduce excess filling material. To minimize polymerization shrinkage, the composite material is applied in layers (increment technique). Eeach layer is cured for 30 seconds. In the occlusal area, the cusp and fissure relief is rebuilt with a small Heidemann spatula as well as a condenser.
A curved scalpel and polishing strips are used for removal of excess material and polishing the interproximal area. In order to finish and polish the occlusal surfaces of the restorations, a flame-shaped diamond burr (red ring), brown and green rubber polishers as well as an occlusal brush are used. The occlusion and articulation are checked thoroughly.
