The Local Effect of Vitamin K2 on Bone Remodeling in Socket Preservation

This study is a randomized controlled trial comparing the effects of socket grafting with crushed vitamin K2 (menaquinone)capsules versus no grafting on bone density and socket dimensions following tooth extraction. Patients are randomly assigned to one of two groups: Study Group (Group I): Patients receive socket grafting with crushed vitamin K2 (menaquinone) capsules. The socket is covered with an absorbent sponge, and non-resorbable sutures are placed to stabilize the graft material and achieve soft tissue stability. Control Group (Group II): Patients undergo socket healing without grafting. The socket is covered with an absorbent sponge, and non-resorbable sutures are placed over it. Outcome measures include bone socket dimensions evaluated immediately after extraction with graft material, as well as assessment after 4 months using cone beam computed tomography (CBCT) radiographs. Additionally, core biopsies are taken at the time of implant placement.
