Description

Technical Field

[0001] This application relates to the field of oral medical technology, and particularly relates to an improved digital positioning and depth guiding plate. Background Art

[0002] A completely impacted tooth refers to a tooth that still exists within the jawbone after the tooth eruption period has passed and has not erupted, and is completely located within the jawbone. It cannot be observed intraorally during clinical examination and can only be detected through imaging examinations. It can occur in any position of the jawbone. Since it may occupy the spatial position of normal teeth, it often causes adjacent teeth to shift, rotate, be blocked from eruption, have root resorption, or be accompanied by odontogenic cystic lesions, etc. Therefore, it is necessary to surgically extract the impacted tooth. Since impacted teeth are often adjacent to normal teeth and important anatomical structures, adjacent tissues may be damaged during the surgical process.

[0003] A related impacted tooth positioning guide plate is divided into two parts: the lower part: tooth-mucosa supported type, and the upper part: bone surface supported type. During the operation, first place the lower part of the guide plate in position, then incise and flap along the incision line, and then place the upper part of the guide plate in position and tightly connect it to the lower part. After removing the bone by fenestration, the impacted diseased tooth is extracted. Although it can accurately locate the impacted tooth and reduce surgical trauma, the two-part design increases the difficulty of guide plate design and production to a certain extent, and the connection between the two ends of the guide plate is prone to errors. At the same time, it increases the clinical operation steps and reduces the surgical efficiency. Utility Model Content

[0049] Combination Figure 1 and Figure 2, an embodiment of the present application discloses an improved digital positioning and depth guiding plate, including: a tooth-supported fixing plate 11, an incision guiding member 2, a positioning and depth determining member 3, and a splitting guide ring member. The splitting guide ring member includes a splitting connecting plate 41 and a splitting ring 42. The tooth-supported fixing plate 11 is sleeved outside the tooth, the inner peripheral side of the tooth-supported fixing plate 11 fits with both sides of the tooth, a connecting column 12 is fixedly arranged on the outer side of the tooth-supported fixing plate 11, the incision guiding member 2 is detachably arranged on the outer side of the tooth-supported fixing plate 11 through a connecting member 5, the positioning and depth determining member 3 is detachably arranged on the tooth-supported fixing plate 11, and one end of the splitting connecting plate 41 is detachably arranged on the outer side of the tooth-supported fixing plate 11; the circumference of the splitting ring 42 is fixedly connected to the end of the splitting connecting plate 41 away from the tooth-supported fixing plate 11; wherein, a third opening 43 is arranged at the connection between the splitting connecting plate 41 and the tooth-supported fixing plate 11. The tooth-supported fixing plate 11 is made of a biocompatible material.

[0050] In the embodiment of the present application, the tooth-supported fixing plate 11 is arranged in a fitting manner with the tooth. It should be noted that before manufacturing the tooth-supported fixing plate 11, after obtaining the oral scan data and CBCT data of the patient, where the oral scan data includes the dental arch and the surface of the oral soft tissue, then the oral scan data is exported in the STL format, the CBCT data is exported in the DICOM format, the data is imported into Mimics software to extract the bone tissue structure of the area of the designed body surface projection type impacted tooth extraction positioning guide plate, after three-dimensional reconstruction, the data is exported in the STL format, and then the CBCT data, the oral scan data and the data after three-dimensional reconstruction are subjected to fitting and registration. While performing the fitting and registration, the tooth-supported fixing plate 11 is designed, and then the bone model and the tooth-supported fixing plate 11 are combined with a biological material and printed by 3D printing technology. Thus, the tooth-supported fixing plate 11 can be accurately obtained.

[0051] The connecting column 12 is arranged in a square shape. The connecting column 12 can be set by 3D printing technology or can be set after printing. Specifically, the embodiment of the present application does not make a specific limitation. The splitting connecting plate 41 and the splitting ring 42 are set according to the jaw model and the doctor's diagnosis data, that is, corresponding splitting connecting plate 41 and splitting ring 42 are set for each patient. Among them, the biocompatible material can be medical-grade polyetheretherketone (PEEK) or polylactic acid (PLA), as long as it has good biocompatibility and corrosion resistance and can ensure that it will not cause adverse effects on the patient's oral cavity during long-term use.

[0052] In specific use, before the operation, the tooth-supported fixing plate 11 is sleeved outside the patient's teeth to ensure that the tooth-supported fixing plate 11 fits closely with the teeth. Then, according to the surgical needs, the incision guiding member 2 is fixed on the supported fixing plate for cutting. After the cutting is completed, the positioning and depth-determining member 3 is replaced for fixation to determine the positioning depth and position of the implant. Immediately, the positioning and depth-determining member 3 is removed and the split connecting plate 41 is fixed on the tooth-supported fixing plate 11. The split ring 42 determines the split position and at the same time is used to accommodate the splitting tool and provide tooth-splitting guidance. During the tooth-splitting operation, the tooth-splitting tool can be placed in the split ring 42 and move along the guidance of the split ring 42 to ensure the accuracy of the tooth-splitting operation. Thus, during the operation, the doctor can sequentially complete the surgical incision, implant positioning, and tooth-splitting operations according to the functional guidance of different guide plate structures, thereby improving the overall accuracy and operation efficiency of the operation.
