Dental Implants Occlusal Overload

Studies have established that occlusal overload frequently led to marginal bone loss or de-osseointegration of effectively osseointegrated implants. The crestal bone around dental implants might be a fulcrum for lever action whenever a bending moment is used, recommending that implants may well be more prone to crestal bone loss by mechanical pressure.
Factors connected with elevated bending overload in dental implants:
• Prostheses based on a couple of implants in the posterior region
• Straight alignment of implants
• Significant deviation from the implant axis in the type of action
• High crown/implant ratio
• Excessive cantilever length (>15 mm within the mandible, >10-12 mm within the maxilla)
• Discrepancy in proportions between your occlusal table and implant mind
• Para-functional habits, heavy bite pressure and excessive premature contacts (>180 µm in monkey studies, >100 µm in scientific testing on people)
• Steep cusp inclination
• Poor bone strength and density/quality
• Insufficient quantity of implants
