Immediate Implant Placement Using Xenograft Mixed with Vitamin D Versus Hyaluronic Acid.

Dental implants in fresh extraction sockets and healed sites have a erratic morphology, creating a wide space defect between the implant and buccal alveolar bone. This defect is critical for implant success, known as a jumping gap. Proper management of this space is essential for esthetic and functional success. Studies show adequate bone fill can be achieved in jumping gaps, but wider gaps increase implant body exposure risk.

The application of biological mediators embedded in the biomaterial can induce specific cell and tissue response, which can improve bone quality and quantity. Dental research has focused on improving bone substitutes by morphologic or bio- chemical modification.
