Abstract

Objectives: This study aimed to enhance Osseo densification by using Platelet-rich fibrin (PRF) on sinus lifting of maxillary implant in class II partially edentulous cases.
Materials and Methods: fourteen maxillary class II partially edentulous patients were selected and divided into two groups. Single implant was inserted in the edentulous region with closed sinus lifting technique for each patient in both groups, for group I implant was placed with the Densah bur drilling system together with PRF while in group II other implant was placed with that same system without PRF. Implant primary stability was measured using Resonance Frequency Analysis by Osstell immediately after torqueing the implants and every two weeks for 2 months. Rate of bone formation was followed up by taking CBCT after implant loading and followed up for one year.
Results: No significant difference was found regarding Osstell values at all follow up appointments for both groups. Regarding the bone formation, the group with PRF there was significant difference than the group without PRF.
Conclusions: Using Densah burs in closed sinus lifting consider very safely and effective technique and using PRF as grafting material in closed sinus lifting enhancing rate of bone formation.
