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

Immediate Implant Placement Using Xenograft As Space Filling Material Mixed with Vitamin D Versus Hyaluronic Acid in Posterior Mandible Region: a Randomized Controlled Clinical Trial.

Immediate implant placement using xenograft as space filling material mixed with vitamin D versus hyaluronic acid in posterior mandible region This study aims to evaluate implant stability and density after placement of immediate implant and Xenograft mixed with Hyaluronic acid or Vitamin D at posterior mandible region

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.
