Dental Implants

• First known use by Maya civilization (600 AD).
• 1952 Dr. Leonard Linkow placed first implant.
  Known to be the father of modern implant
  dentistry.
• 1959 Stefano Melchiade Tramonte saw titanium
  screw could support prosthesis. Human trial
  results (1966).
• Bone grafts required.

3
Bone Grafting

• Surgical procedure to replace damaged or
  unhealthy bone.
• Patients suffering from periodontal disease.
  Dental implants needed.
• Osteoconduction vs. Osteoinduction
• Graft material sources
• Autograft
• Allograft
• Biomaterials (Metal, Ceramic, Synthetic Polymers,
  etc.)

4
Fast Response Biomaterial

• Dr. Cameron Lutton - Inflammatory response
  polymer.
• Healing process
• Structure attracts/repels proteins.

5
Results

• Luttons preliminary results were successful.
• Presented to Orthopedic Research Society (2008).
• Currently animal trials. (Limitation)
• Begin treatment of patients with bone disease.

Future Innovations

• Titanium foam implants (Fraunhofer Institute for
  Manufacturing Technology and Advanced Materials
  Research).
• Laser cut implants, degradable (Institute for
  Laser Technology).
• Closer to biological joint replacement.
• Bone grafts still remains a competitive market.
