1results about How to "Avoid photodamage" patented technology

This invention belongs to the field of orthodontic instrument technology, specifically a periodontal targeted near-infrared light bimaxillary therapy device that protects tooth crowns. It includes a protective brace and a bimaxillary irradiation device. The protective brace includes a maxillary protective brace and a mandibular protective brace, each comprising a lingual plate and a labial plate. The labial plate includes a cervical sleeve and a receiving groove. The bimaxillary irradiation device includes an outer irradiation plate, an inner irradiation plate, and a flexible occlusal plate. Near-infrared laser lamps are installed on the outer and inner irradiation plates. This invention achieves simultaneous irradiation of the labial and lingual periodontal tissues of both jaws, significantly improving orthodontic efficiency. It can simultaneously irradiate the entire periodontal area of ​​both jaws in a single treatment, eliminating the need for separate upper and lower jaw procedures, shortening treatment time, achieving simultaneous activation of all periodontal tissues, and improving tooth movement efficiency. The bimaxillary irradiation device uses precise lamp placement according to the periodontal ligament area, working in conjunction with the protective brace to fully cover the protective crown, synergistically avoiding thermal and light damage.
