Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The amount of bone formed on the implant. Timepoint: Intervals of 12 weeks (in the mandible) and 16 weeks (in the maxilla) after stage 2 surgery. Method of measurement: Clinically determined by the percentage of exposed implant threads in the second stage of surgery.;Implant success rate. Timepoint: At intervals of 12 weeks (in the mandible) and 16 weeks (in the maxilla) after surgery. Method of measurement: Implant success rate is determined by reflection frequency analysis (RFA) test using Osstell Mentor (Integration Diagnostics Ltd., Göteborg, Sweden) as well as the application of a reverse torque force of 35 N / cm by the reverse mode of the implant surgery engine and angle 20: 1, It is measured during the second stage of implant surgery. In the osstell mentor device, according to osseointegration a number between 1 and 100 is shown. This number is the Implant Stability Quotient(ISQ) . The higher the ISQ displayed by the device, the higher the degree of integration. In evaluation by reverse torque force, success is expressed as stable and implant failure as unstable. | — |
Secondary
| Measure | Time frame |
|---|---|
| Periodontal tissue healing rate on implant. Timepoint: At 1, 2 and 4 weeks after surgery. Method of measurement: periodontal tissue healing rate is expressed as the absence of membrane and bone graft exposure(A), only membrane exposure (B), or membrane and bone graft exposure (C).;The incidence of infection in the surgical area. Timepoint: At 1, 2 and 4 weeks after surgery. Method of measurement: The incidence of infection in the area is measured and expressed as the presence (+) or absence (-) of infection according to the symptoms of infection in the area (swelling, pain, persistent erythema and secretion of pus).;Patients' postoperative pain. Timepoint: In the first, third and tenth day after surgery. Method of measurement: The amount of pain after surgery of the patient is recorded using a VAS scale in a questionnaire designed for this purpose. In this scale, the amount of pain is classified from 0 to 10 based on the severity of pain.0 is the absence of pain and 10 is the presence of the most severe pain possible. | — |
