Posterior Complex Carious Proximal Cavities
Conditions
Brief summary
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.
Detailed description
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.
Interventions
OTHERBulk-fill ormocer (Admira fusion x-tra, Voco, Cuxhaven, Germany) with Precontoured circumferential matrix system (Palodent 360, Dentsply Caulk, Millford DE, USA)
A suitable size precontoured circumferential matrix band (Palodent 360, Dentsply Caulk, Millford DE, USA) will be selected and placed. Teeth separation will be acquired with a suitable size wedge (Palodent V3, Dentsply Caulk, Millford DE, USA) and a separation ring (Palodent V3 universal ring, Dentsply Caulk, Millford DE, USA). Then the bulk-fill ormocer (Admira fusion x-tra, Voco, Cuxhaven, Germany) will be applied and light cured according to the manufacturer instructions.
OTHERBulk-fill ormocer (Admira fusion x-tra, Voco, Cuxhaven, Germany) with Precontoured sectional matrix systym (Saddle matrix, TORVM, Moscow, Russia)
A suitable size precontoured sectional matrix band (Saddle matrix, TORVM, Moscow, Russia) will be selected and placed. Teeth separation will be acquired with a suitable size wedge (fixing wooden wedges, TORVM, Moscow, Russia) and a separation ring (Delta ring, TORVM, Moscow, Russia). Then the bulk-fill ormocer (Admira fusion x-tra, Voco, Cuxhaven, Germany) will be applied and light cured according to the manufacturer instructions.
OTHERBulk-fill resin composite (X-tra fill, Voco, Cuxhaven, Germany) with Precontoured circumferential matrix system (Palodent 360, Dentsply Caulk, Millford DE, USA)
A suitable size precontoured circumferential matrix band (Palodent 360, Dentsply Caulk, Millford DE, USA) will be selected and placed. Teeth separation will be acquired with a suitable size wedge (Palodent V3, Dentsply Caulk, Millford DE, USA) and a separation ring (Palodent V3 universal ring, Dentsply Caulk, Millford DE, USA). Then the bulk fill resin composite (X-tra fill, Voco, Cuxhaven, Germany) will be applied and light cured according to the manufacturer instructions.
