Clinical Trial Summary

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

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in implant stability	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.	immediately, at 1 week, at 3 months
Primary	Change in Bone density	The Patients will be asked to do CBCT immediately after surgery and after 3 months	immediately, after 3 months
Primary	Change in bone formation	Amount of bone formed buccal and lingual to the implant will be assessed using CBCT	immediately, after 3 months
Primary	Marginal bone loss	it will be assessed using CBCT	after 3 months
