Using of Implants With a Sloped Platform Edge

Status Completed

Clinical Trial 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.

Clinical Trial Description

The research aimed to compare the clinical and radiological assessment of soft and hard tissues surrounding implants with a sloped edge platform. Thirty patients with alveolar ridge atrophy were examined at the Department of Surgical Dentistry of the E.V. Borovsky Institute of Dentistry, I.M. Sechenov First Moscow State Medical University. These patients displayed a deficiency in hard tissue width, necessitating augmentation for dental implant placement. Patients were randomly divided into two groups based on treatment methods. 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 underwent treatment with implants of a "standard" design combined with bone grafting. Gender and age characteristics were matched between the groups for comparability. Patients in the first group were implanted with sloped edge platform implants, while the second group received implants with a different design (Dentsply Sirona CIS, ASTRA TECH Implant System, registered in Russia on 21/12/2019, No. РЗН 2015/3214) incorporating guided bone regeneration. All groups underwent muco-periosteal flap mobilization followed by wound closure without tension using simple interrupted sutures. In the early postoperative phase, antibacterial and anti-inflammatory therapy was combined with the use of local antiseptics for daily care. Implant uncovering with healing abutment installation occurred 4-6 months post-intervention. The postoperative assessments included evaluating soft tissue condition, bone resorption, analgesic consumption, operation duration, edema, keratinized mucosa width, implant stability quotient, pain severity, and quality of life. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
