Embodiment
[0039] A supragingival scaling device based on high repetition rate femtosecond pulsed laser, such as figure 1 As shown, it includes a light source module, a trajectory control module, and a supragingival cleaning module; the supragingival cleaning module includes a maxillary supragingival cleaning module and a mandibular supragingival cleaning module;
[0040] The light source module generates femtosecond pulsed laser with high repetition rate, which is transmitted to the supragingival cleaning module of the upper jaw and the supragingival cleaning module of the mandible, and at the same time, the trajectory control module controls and monitors the femtosecond pulsed laser with high repetition frequency in real time for cleaning and treatment of the supragingival area. The working track of the module performs high-precision and high-efficiency supragingival cleaning on all teeth of the upper and lower jaw arches in a non-contact and heat-free manner.

Abstract
The invention discloses a supragingival cleaning device based on high repetition frequency femtosecond pulse laser. The supragingival cleaning device includes a light source module, a trajectory control module, and a supragingival cleaning module; the supragingival cleaning module includes a maxillary supragingival cleaning module and a mandibular supragingival cleaning module; The second pulse laser is transmitted to the maxillary supragingival cleaning module and the mandibular supragingival cleaning module respectively. At the same time, the trajectory control module controls and monitors the working trajectory of the high repetition frequency femtosecond pulse laser in the supragingival cleaning module in real time, with non-contact, In a non-thermal injury way, high-precision, high-efficiency supragingival scaling is performed on all teeth in the upper and lower dental arches at the same time.
Description
technical field [0001] The invention relates to the technical fields of biomedicine and ultrafast optics, in particular to a supragingival cleaning device based on high repetition frequency femtosecond pulse laser. Background technique [0002] Periodontal disease is a common and frequently-occurring disease of the human oral cavity, including two types of diseases: gingival disease that only involves gingival tissue and periodontitis that affects deep periodontal tissues such as periodontal ligament and alveolar bone. The fourth national oral health epidemiological survey report shows that the detection rates of gingival bleeding in the 35β44 and 65β74 age groups in my country are 87.4% and 82.6%, respectively, and the detection rates of dental calculus are 96.7% and 90.3%, respectively. %, the detection rates of deep periodontal pockets (β₯6mm) were 6.9%, 14.7%, and the detection rates of attachment loss (β₯4mm) were 33.2%, 74.2%. Compared with the results of the third natio...
