Oral soft tissue metabolism monitoring system and method

Abstract

The invention relates to an oral soft tissue metabolism monitoring system which comprises a light source module (1), a collecting module (2) and an image processing module (3). The light source module(1) comprises a light source controller (11), an infrared laser (12), an orange light source (13) and a green light source (14). The input end of each light source is connected with the light sourcecontroller (11) through a respective drive device, and the output end of each light source is connected with an optical fiber coupler (16). The collecting module (2) comprises a handle (21), a diffusion piece (22) and a miniature image sensor (23). The diffusion piece (22) and the miniature image sensor (23) are installed on the handle (21). The diffusion piece (22) is connected with the optical fiber coupler (16) through an optical fiber. Large-range illumination is conducted in an oral cavity. The image processing module (3) is connected with the miniature image sensor (23). Analysis is conducted according to collected images to obtain the microcirculation blood supply information of oral soft tissue. Compared with the prior art, the system has the advantages of being large in collectingrange and convenient to operate.

Description

technical field [0001] The invention relates to a monitoring system for oral soft tissue (gingiva, oral mucosa, etc.) health status, in particular to a system and method for monitoring oral soft tissue metabolism. Background technique [0002] The health of soft tissue is one of the key factors for the success and long-term retention of implant restoration. The local gingival and mucosal blood flow conditions reflect the tissue perfusion ability, tissue anti-infection ability, and the ability of the graft to integrate with the implanted bed tissue. [0003] At present, the cases of oral soft tissue defects caused by trauma or tooth loss have been on the rise; and in order to restore the appearance of the tissue and ensure the health and aesthetics of the transplanted part of the surrounding tissue, free soft tissue transplantation is required. Therefore, real-time monitoring of the blood flow status of the gums after soft tissue surgery and the blood flow reperfusion in the ...

AI Technical Summary

Problems solved by technology

[0004] In the past, the evaluation of blood circulation in soft tissues was mostly done by naked eyes or direct observation during surgery. This subjective judgment lacks objective basis and cannot be used in clinical research.

[0005] There are two types of observation methods for skin microcirculation in the existing literature: in vitro specimens and in vivo observations. The in vitro methods are mainly to perform microvascular perfusion, casting, and staining of tissue sections on isolated specimens, but they can only be used for death or death. Observation of microvessels in isolated organs after surgery cannot be used clinically

[0006] Methods for observing blood flow in living tissues include laser Doppler imaging, laser scanning confocal microscopy, optical coherence tomography, orthogonal polarization spectral imaging, etc., some of which are limited by the equipment itself (such as equipment volume It is too large to be placed in the mouth), and cannot be applied to oral clinical research. At present, laser Doppler imaging technology is widely used in clinical research

Laser Doppler technology also has its limitations. First of all, its results are greatly affected by the position of the probe, and the signal-to-noise ratio is low. It can only achieve single-point measurement, and it is difficult to provide a wide range of blood metabolism information.
