NCT06404944

Brief Summary

An interventional prospective randomized clinical trial (RCT) was conducted in parallel groups. The sample size consisted of 30 patients who were randomly assigned to two groups based on the type of surgical intervention. The first group received implants with a sloped edge platform (Dentsply Sirona CIS, ASTRA TECH Implant System, registered in Russia on 21/12/2019, No. РЗН 2015/3214). The second group received implants with bone grafting. The assessment in the postoperative period included evaluating the condition of the soft tissues, bone resorption, number of analgesics, duration of the operation, edema, keratinized mucosa width, implant stability quotient, pain severity, and quality of life.

Outcome Measures

Primary Outcomes (1)

  • determination of the level of the marginal bone

    This parameter was determined by analyzing radiovisiography performed on the Vatech EzSensor device (Vatech, South Korea) with an X-ray load of 2μSv 6 months after the operation (after completion of prosthetics). The radiographs were studied using X-ray software on a 27-inch monitor (ASUS) with a screen resolution of 2560 × 1440 pixels. The marginal bone level was assessed using a measuring tool built into the program. The reference point for measurement was the implant shoulder on the medial and distal sides.
