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.

The study is designed as a randomized controlled trial to investigate the effects of socket grafting with crushed vitamin K2 (menaquinone) capsules compared to no grafting on bone density and socket dimensions following tooth extraction.

Participants: Patients scheduled for tooth extraction are enrolled in the study and randomized into two equal groups.

11. Interventions

- Patients were randomly divided into two equal groups.

In both groups:

Tooth extraction will perform under local anesthesia All sockets were thoroughly curetted to remove granulation tissue, followed by irrigation and rinsing with sterile saline.

Bone density and socket dimensions will be evaluated immediately after extraction with graft material and after 4 months by using a cone beam computed tomography (CBCT) radiograph and at the time of implant placement core biopsy will be taken.

In group I (study): the socket will be filled with crushed capsule of vitamin k211. Interventions

In group I (study): the socket will be filled with crushed capsule of vitamin k2 and cover with an absorbent sponge a Figure of eight tension-free non-resorbable 3-0 sutures will be placed over the filled socket to stabilize the graft material in the socket and to achieve soft tissue stability.

in group II (control): the socket will be left to heal without grafting, and it will be covered with an absorbent sponge. A figure-of-eight tension-free non-resorbable 3-0 sutures will be placed over the socket.
