Problems solved by technology

[0004] Therefore, the present invention aims to provide a method for measuring oral bone density and its equipment to solve the problem that the density image of bone tissue cannot be directly obtained in the prior art, and it is necessary to rely on the dental clinician to observe the patient's tooth film with the naked eye, and rely on the reconstruction of the bone density image in the image. The sparseness of the spatial arrangement of the trabeculae is used to conduct bone density of the jaw, resulting in poor accuracy of bone density assessment

Abstract

An oral cavity bone mineral density measuring method comprises the following steps that S1, high-energy X-rays are sent to a scanned body; S2, the high-energy X-rays penetrating through the scanned object are received; attenuation processing is conducted on the high-energy X-rays to obtain low-energy X-rays, and the low-energy X-rays are received; and S3, the processing unit obtains high-energy X-rays and low-energy X-rays penetrating through the scanned body, and a density image of the bone tissue is obtained through an image reconstruction algorithm. By means of the method, the density image of the bone tissue can be obtained, and therefore the problem that in the prior art, an oral clinician needs to observe a dental film of a patient with naked eyes, oral jawbone bone density evaluation is conducted according to the sparse degree of spatial arrangement of bone trabecula in a reconstructed image, and consequently bone density accuracy evaluation accuracy is poor is solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and mainly relates to a method for measuring oral bone density and equipment thereof. Background technique [0002] Dental implants are by far the most ideal way to restore missing teeth, and the implementation process is quite complicated. Before implanting dental implants, patients first need to perform radiographic examinations on the pre-implantation sites to evaluate various aspects, including gum space, alveolar bone hardness, Implantation angle and depth, etc. Among them, the assessment of bone density in the implant area is a key step in the success of dental implants. How to measure the bone density of the jaw accurately, effectively and practically is important for the formulation and prognosis of implant and periodontal surgery. The judgment has a very important guiding role. In addition, oral bone loss is an important factor affecting the retention of teeth and the success ...
