Introduction: Tooth movements require a stable base. The most stable endo-buccal base is bone, thus temporary bone-anchoring techniques have been well developed to date. Literature review of different bone-anchoring techniques reveals limitations in their regular use, particularly when it comes to mini-screw stability. The purpose of this paper is to present a reliable temporary bone-anchoring technique pushing the limits of orthodontic treatments. Technique: The device is made of one to two micro-screws connected to a steel or titanium molybdenum alloy (TMA®) wire going through one or two loops. The device is then inserted into the bony base after a mucoperiosteal incision. The connecting arm, which emerges through the mucosa, is then connected to the teeth to be pulled in a direct or indirect manner. Comments: This device provides advantages in terms of reliability, versatility of orthodontic movements, simplicity in terms of protocol installation and removal, and poses no anatomical risk. Conclusion: This is an orthodontic surgical technique that provides a real benefit to the patient.
Key words: micro-screw / orthodontic movement / bone anchorage
