Platelet Rich Fibrin and Concentrated Growth Factors on Osseointegration of Immediate Implants
A Comparative Study Between the Effect of Platelet-rich Fibrin and Concentrated Growth Factors on Osseointegration of Immediate Implants (a Randomized Clinical Trial)
This study will involve 14 patients with mandibular premolars indicated for extraction and immediate replacement. The patients will be randomly allocated into two groups and each patient will receive one implant. In Group A, a CGF membrane will be laid in the implant cavity. While in Group B, a PRF membrane will be laid in the implant cavity. Bone graft material will be applied to fill the empty parts of the socket.
Resonance frequency measurement will be done using the OSTELL device intraoperatively, at the 1st week and after 3 months. Cone-beam computed tomography will be done preoperatively, immediately following surgery, and after 3 months

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Change in implant stability
Tidsramme: immediately, at 1 week, at 3 months
|
Osstell instrument (Integration Diagnostics, Goteborg, Sweden) with Smartpeg™ (Integration Diagnostics, Goteborg, Sweden), a transducer suitable for implants will be used to assess stability of implants by RFA.
ISQ (implant stability quotient) will be obtained from the measurement results.
During measurement, the Smartpeg™ will be placed over the location of implant prosthesis and the Osstell probe will be approximated to it from the buccal, palatal, mesial and distal aspects of the implant giving four ISQ values.
A mean ISQ for each implant is then calculated by averaging the four values.
The ISQ values of the implants will be measured during the operation, at the first week and three months after the operation.
