Abstract:

In clinical practice, few orthodontic methods could be used to achieve simple mesial movement of molars, mesial movement of anterior teeth, anterior movement of whole dentition, or correction of midline of dentition. However, they are complicated or they have many side effects. Combining two cases, this paper introduces a new type of spring pushing device, which could achieve the whole dentition forward, the posterior teeth forward to close the gap, the anterior teeth forward, or the midline correction. The spring pushing device is composed of four components, such as the force control lever, the force pushing spring, the force transfer angle, and the force arm. The biomechanical structure principle and clinical application effect of the device were analyzed and discussed to provide a new treatment method for similar clinical patients.

Key words: novel spring, orthodontic advancement, fixed appliance, skeletal anchorage
