IRCT20200825048522N1 IRCT 2020-09-01 Islamic Azad University Comparison of immediate and delayed implantation Comparison of Immediate and Delayed Implantation on Insertion Torque and Primary Stability 2019-10-02 anticipated 8 Complete https://irct.ir/trial/50524 interventional Randomization: Not randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Single, Purpose: Treatment. N/A Treatment of edentulous with implant. Intervention 1: Intervention group:The site to receive the implant immediately. After the atroumatic extraction of the tooth and then the full thickness flaps will be prepared under local anesthesia and the osteotomy areas will be prepared according to the manufacturer's instructions. Exploratory examination of the socket after extraction will be performed by the probe to identify defects - especially in the buccal wall - which in this study are considered immediate contraindications. According to the existing protocol for one-step surgery, two implants will be placed in each patient by a calibrated torque wrench for implant placement and torque measurement. The amount of torque for each implant is measured relative to time and the maximum final value will be calculated in Ncm. Immediately after implant placement, an RF analyzer will be used to directly measure initial stability. The resulting data will be displayed as a graph with RF-domain axes. The RF values calculated from the amplitude peak will be displayed as a quantitative scale from zero to 2 called the Implant stability quotient (ISQ). Thus, the higher the ISQ, the higher the stability of the implant. After surgery, the ISQ value for each implant will be measured by the same surgeon (initial stability). The flaps are returned to their original position by the sling suture. All implant stability measurements are repeated three times for each case and the average of three numbers will be recorded as the final value. If the difference between these three numbers in an implant is more than one unit, or indicates an error device, the measuring device will be disconnected, reconnected and the measurement will be performed again. Intervention 2: Control group: On the edentulous side, full-thickness flaps will then be provided under local anesthesia, and osteotomy areas will be prepared according to the manufacturer's instructions. A scale will be placed for implant placement and torque measurement. The amount of torque for each implant is measured relative to time and the maximum final value will be calculated in Ncm.
