简要总结
The use of ormocers with precontoured circumferential matrix system allow predictable restoration of complex proximal posterior cavities with less time and fewer tools required to produce optimum proximal contact size, location and magnitude and restoration durability with higher wear resistance.
详细描述
After profound local anesthesia, conservative cavity preparations will be performed with high-speed burs (no.:330, Meisinger, Germany) under constant refrigeration. Intermittent rotary instrument contact with tooth limited to the removal of compromised enamel. The cavity outline is restricted to the removal of carious tissue with spherical carbide burs at low speed. In the removal of defective restorations, the friable enamel and remnant carious tissue will be removed in the same way. All teeth will be restored using a rubber dam. The universal bonding agent (Voco, Cuxhaven, Germany) will be applied with previous selective enamel etching with 37% phosphoric acid for 30 seconds. These materials will be inserted following the manufacturer's instructions.
After cavity preparation, each participant will choose a random number from an opaque sealed envelope, then patient will select from random numbers prepared by Y.H. to randomly assign interventions to the participant oral cavity.
All restorations will be prepared, restored, finished and polished by one operator.
