Calcium Based Dental Bone Cement for Dental Implant Osseointegration

Improved Dental Bone Cement for Stabilizing Dental Implants, Preventing Dental Implant Failure

Approximately 1.2 million dental implant procedures are performed, and 80,000 implants fail, in the United States annually. One of the most important factors for dental implant success is bone osseointegration. Patients with compromised healing, such as the elderly, smokers, diabetics, and those who have undergone radiation in the head or neck, experience significantly increased dental implant failure as compared with healthy patients. The researchers at the University of Minnesota have developed a dental bone cement that can be primarily used for initially unstable dental implants typically found in low quality bone of elderly and patients with compromised healing capacity.

A Non-Resorbable, Rapidly-Setting and Sustainable Dental Implant Cement

The innovation provides a non-resorbable dental bone cement of Portland cement, an accelerant and, dispersant. The cement has excellent biocompatibility, superior molding capacity, rapid set-up, and is not easily washed away by blood, which makes it highly useful in providing initial stability to the dental implant. The created bone cement also has relatively high tensile strength which extends its clinical applications in stress-bearing areas. The bone cement is easy to use and has small particulate size to infiltrate into trabecular bone to create "hybrid zone" without fracturing the hard but weak trabeculae.

BENEFITS OF DENTAL CEMENT FOR USE IN IMPLANTS:

  • Stays in place; adequate viscosity and rapid-set to prevent wash-out by blood and dental implant failure
  • Reliable; load-bearing capacity and long-term fatigue resistance
  • Easy to use; hydrophilic, flowable, small particulate size to infiltrate into trabecular bone to create "hybrid zone" without fracturing the hard but weak trabeculae
  • Excellent biocompatibility and osteoconductivity
