Problems solved by technology

However, the commonly used sub-angle projection technology is time-consuming, prone to distortion and deformation, while the parallel projection technology can meet the requirements of image accuracy and small distortion, but the parallel projection technology is cumbersome to operate when using a general-purpose X-ray film holder. more time-consuming and difficult to achieve
At the same time, the implant is located in the alveolar bone and cannot be seen outside the body, so it is difficult to determine its three-dimensional direction when shooting

Embodiment Construction

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the present invention Embodiments, and all other embodiments obtained by persons of ordinary skill in the art without creative efforts, all belong to the scope of protection of the present invention.

[0034] (1) Pre-design the X-ray clips using a reverse engineering software program. According to the size of common imaging plate, build 2 intersecting plates (occlusal plate and imaging plate). Add a guide post in the center of the occlusal surface and a clip near the imaging plate.

[0035] (2) Based on the three-dimensional data (A) after the crown restoration design of the implant patient is completed, design the attachment structure (B) that matches the upper crown of the ...

Abstract

The utility model discloses an X-ray film holder for implant evaluation, relates to the field of oral care, and in particular relates to an intraoral occlusion wing panel occlusion fixing projection stent for shooting dental crowns of upper and lower jaw teeth and occlusion conditions of the upper and lower teeth. Clinical data of a patient before and during an operation are used in combination with computer aided design and computer aided manufacturing technology (CAD-CAM), the stent is matched with the intraoral condition of the patient, and the stability of the stent is good.

Description

technical field [0001] The invention relates to the field of oral care, in particular to an X-ray film holder for implant evaluation and a manufacturing method. Background technique [0002] Oral implants are more and more accepted by people, and with the development of the times, the proportion of oral implant treatments is getting higher and higher. After implantation, it is necessary to accurately evaluate the position of the implant and the changes in the surrounding marginal bone level through radiographs, which is crucial for monitoring the therapeutic effect of dental implants. However, the commonly used sub-angle projection technology is time-consuming, prone to distortion and deformation, while the parallel projection technology can meet the requirements of image accuracy and small distortion, but the parallel projection technology is cumbersome to operate when using a general-purpose X-ray film stand. more time-consuming and difficult to achieve. At the same time...
