Aim: To show the evolution of the authors’ clinical experience in the application of the Straumann Orthosystem method for anterior anchorage in nonextraction patients. Methods: The Straumann Orthosystem has been combined with different traditional distalizing devices, passing from indirect to direct loading methods. Results: The authors prefer the direct loading method, which minimizes coronal tipping of the first maxillary premolars. Among the different appliances examined, a modified version of the Hilgers pendulum provides better handling and easier activation, due to the extractable springs. Conclusion: The Straumann Orthosystem can be used with a direct or indirect load, but the authors suggest its use with the direct loading method to avoid reciprocal forces in the anterior sector and to aid the contemporaneous distalization of intermediate dental elements. The surgical implant insertion is simple and without serious risks, and patient compliance is not required. World J Orthod 2002;3:135–139.
