Mini Implants for Long-Term Use? | OsseoNews Discussions on Dental Implants: "Mini-implants have the advantages of low cost, simple surgical placement and high versatility, have moderate success rates and are easy to insert when anatomic measurements are carefully considered. When failures are noted, retrieving the loosened one and/then inserting another mini-implant has little discomfort and is usually well accepted by patients. A vast majority of clinicians believe that implants not requiring surgical preparation have higher failure rates, while implants with better stability require flap surgeries for insertion and removal. Whereas conventional or modified oral implants have been shown to successfully serve as anchorage for orthodontic appliances, mini-implants failed to reach these high success rates. When the high failure rates of mini-implants are under evaluation two main factors have to be considered. The biomechanical loading of peri-implant bone as well as the time schedule of loading have been shown to have a major impact on the peri-implant bone healing and can be assumed to determine the clinical fate of mini-implants. Therefore, mini-implants can serve as anchorage for orthodontic force systems when loads do not exceed a tolerable strain level. It is important to note that the amount of stresses and strains are dependent on the geometry of the screw as well as on the mechanical properties of the implant and bone. The"
