Technical Field
The invention relates to the field of oral care, in particular to an X-ray film holder for implant evaluation and a manufacturing method thereof.
Background
The oral implant is more and more accepted by people, and with the development of times, the proportion of oral implant treatment is higher and higher. After the implantation, the position of the implant and the change of the bone level of the peripheral edge of the implant need to be accurately evaluated through X-ray pictures, which is important for monitoring the treatment effect of the dental implant. However, the commonly adopted sub-angle projection technique is time-consuming in operation, easy to distort and deform, while the parallel projection technique can meet the requirements of accurate images and small distortion, but the parallel projection technique is complicated in operation, more time-consuming and difficult to achieve when a general X-ray film bracket is used. Meanwhile, the implant is positioned in the alveolar bone and invisible in vitro, and the three-dimensional direction of the implant is difficult to determine during shooting. In addition, the longitudinal axis of the implant may be in an oblique position relative to the implant, thus requiring the use of customized positioning devices to ensure that the X-ray film is parallel to the implant during clinical operation.
The invention designs a method for manufacturing a customized X-ray film shooting bracket suitable for an implant by combining computer aided design and computer aided manufacturing (CAD-CAM) by utilizing three-dimensional data of a CT and the implant in an implantation operation and combining the intraoral condition of a patient, and provides an oral clinical treatment process with strong clinical operability, simplicity, time saving and good shooting effect.

The manufacturing method of the X-ray film holder comprises the following steps:
(1) the X-ray clamp is pre-designed using a reverse engineering software program. 2 intersecting plates (bite plate and imaging plate) were built according to the size of a common imaging plate. A guide post is added at the center of the occlusal surface, and a clamp is added near the imaging plate.
(2) Exporting the design data of the step (1) into a standard three-dimensional model file. Using three-dimensional design software, a pre-designed X-ray film clip is imported into the CAD software program as an accessory.
(3) Making the implant crown/abutment. A three-dimensional digital scan model with an implant specific scan is obtained, either worn inside the portal or fixed in the final plaster model. And importing the scanning data into a CAD software program, and designing the crown restoration body/abutment on the virtual abutment by utilizing the implant crown design process.
(4) And designing a customized X-ray film bracket. And (3) placing a positioning guide plate near the implant crown/abutment in three-dimensional design software, matching the accessory in the step (2) with the virtual implant, adjusting to a proper position to form a self-defined X-ray film bracket, and exporting design data into an STL file or a corresponding 3D model file.
(5) And finishing the X-ray film bracket. And (4) printing the STL file in the step (4) into a real object by using a 3D printer.
(6) X-ray imaging is performed. And (4) putting the X-ray imaging plate into the film frame printed in the step (5). When radiography is carried out, a parallel projection technology is used, and a radiation head is aligned to a circular ring of an X-ray clamp to directly shoot, namely parallel projection.
Preferably, the software program is common three-dimensional engineering software in the market.
Preferably, the imaging plate is eventually parallel to the implant axis.
Preferably, the bite plate and imaging plate, guide post and clamp are all pre-designed.
Preferably, the implant crown may be a temporary prosthesis, a final prosthesis or an implant abutment.
Preferably, the accessory in step (4) is customized to match the target tooth.
Preferably, the 3D printer is a commercially available printer, requiring no additional customization.
Preferably, the printing support material is a medical 3D printing material.
Compared with the prior art, the invention has the beneficial effects that:
(1) the imaging plate, the implant and the X-ray projection ring are parallel, and the parallel projection effect is easy to obtain.
(2) The clinical data before and during the operation of the patient are utilized, and the economic and time expenditure of the additional burden of the patient is not needed.
(3) The clinical data before and during the operation of the patient are used, the bracket is matched with the intraoral condition of the patient, and the stability of the bracket is good.
(4) The problems of inconvenient X-ray film shooting, long time consumption and easy deformation of images after clinical planting are solved.
(5) The software and the printing equipment are common in the market, easy to obtain and high in popularization degree.
(6) The operating program can be embedded into oral professional software, and the working efficiency is further improved.
(7) Because the accessory is customized individually, the bracket can be directly bitten without being held by hands during clinical use, and instability caused by hands in the shooting process is avoided.
(8) Because the accessories are customized individually, the bracket can be directly bitten without holding by hands in clinical use, and bacterial pollution caused by hand hygiene is avoided.
