- - Bone augmentation is a procedure that addresses bone defects in dental implant treatments by using a prosthetic material covered with a titanium mesh that is shaped to fit the defect.
- - The Selective Laser Melting (SLM) method allows for the customization of the titanium mesh based on preoperative CT scans, resulting in quicker surgeries and better bone shape regeneration compared to traditional methods.
- - In two case studies using the SLM titanium mesh, both patients healed without complications, suggesting this method could be a promising option for bone augmentation in dental implants.
