About this study

Official title: The Use of Implants With a Sloped Platform Edge in Patients With Ridge Atrophy

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.

Read the detailed 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: Day 180 compared to the 0th day (initial value)

The record lists 1 site in Russia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

determination of the level of the marginal bone (time frame: Day 180 compared to the 0th day (initial value)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 May 2024.
