Bone defect rehabilitation using lyophilized bone preshaped on a stereolithographic model

Area of Science:

• Oral surgery
• Regenerative medicine
• Biomaterials

Background:

• Bone grafting is crucial for dental implant success.
• 3D models aid surgical simulation and visualization of anatomical structures.
• Xenogenic bone and stereolithography offer advanced bone defect reconstruction.

Observation:

• A 56-year-old woman presented with an anterior maxilla bone defect.
• The defect was reconstructed using a preshaped lyophilized xenogenic bone block on a stereolithographic model.
• Bone regeneration was achieved with xenogenic grafting and a barrier membrane.

Findings:

• Postoperative follow-up and a 7-year evaluation were conducted.
• Tomographic examination after 7 years confirmed bone maintenance at the grafted site.
• The treatment demonstrated long-term success in bone regeneration.

Implications:

• Stereolithographic models and xenogenic bone grafts are effective for complex bone defect reconstruction.
• This approach offers a predictable method for achieving long-term bone stability in dental implantology.
• The findings support the use of advanced techniques for enhancing patient rehabilitation outcomes.
