Comparison of platelet-rich fibrin and cellulose in palatal wounds after graft harvesting.

Aim: The aim of the present study was to compare patient morbidity and healing outcomes of free gingival graft (FGG) harvesting at palatal donor sites and after using platelet-rich fibrin (PRF) and oxidized regenerated cellulose (ORC). FGG harvesting leaves open palatal wounds, which heal by secondary intention. Patients might experience discomfort or pain during the first 2 weeks of healing.

Comparative study of torque resistance and microgaps between a combined Octatorx-cone connection and an internal hexagon implant-abutment connection.

Statement Of Problem: Although the implant-abutment connection may prevent crestal bone loss around dental implants, its failure often leads to treatment failure. Microgap and micromovement of the implant-abutment connection could be causes of bone resorption around dental implant neck.

Purpose: The purpose of this study was to compare torque resistance and microgaps between a new cone and index connection (Octatorx) and an internal hexagon implant-abutment connection (Internal hex).
