What is Bone Regeneration?

Bone regeneration is a fundamental procedure aimed at restoring the loss of bone tissue in the jaw and ensuring a sufficient foundation for the placement of dental implants or other prosthetic restorations.

Why is it necessary?

Bone loss can be caused by:

• Tooth extractions without immediate restoration.
• Advanced periodontitis.
• Trauma or fractures.
• Infections or cysts.
• Natural bone resorption over time.

Without sufficient bone substrate, the placement of implants becomes risky or even impossible.

What grafts are used?

• Autografts: Bone taken from another site of the patient's own body.
• Allografts: Processed human bone from graft banks.
• Xenografts: Bone materials of animal origin.
• Synthetic grafts: Artificial materials that promote the growth of new bone.

The choice of material is based on the needs of each case and the patient's medical history.

Bone Graft Placement Procedure

Following the appropriate clinical and imaging evaluation, the procedure is generally performed under local anesthesia. The approach to the bone defect is made through an incision in the mucosa. The bone graft is placed in the desired position and is usually covered with a special membrane. The surgical wound is sutured, and the healing period follows. In some cases, simultaneous implant placement is possible.

Factors that affect the success of bone regeneration:

• Good blood supply to the area.
• Stability of the graft and absence of microbial infection.
• General health condition of the patient (e.g., diabetes, smoking).
• Selection of appropriate surgical technique and materials.
• Patient's compliance with post-operative instructions.

Conclusion

Bone regeneration of the jaws is an essential step for the successful placement of dental implants when the bone substrate is insufficient. With proper preparation and guidance from a specialized professional, optimal aesthetic and functional results can be achieved.
