Description

Technical Field

[0001] This utility model relates to the fields of oral implant restoration and digital dental technology, and in particular to an implant restoration scanning rod with screw anti-loss and angle recognition. Background Technology

[0002] In the field of oral medicine today, more and more patients with missing teeth are choosing implant restoration to improve their oral condition and enhance their quality of life. Implant restoration is even called the third set of teeth for humans and is favored by many patients. As a result, more and more patients after implant surgery need to take oral impressions and then send them to a denture processing factory for denture fabrication. The conventional method for implant impressions is to install a special transfer bar in the mouth, and then use a tray and silicone rubber to take the impression. This method is not very comfortable because it requires a large amount of fluid silicone rubber to be injected into the patient's mouth, and some patients cannot take an impression, so it has certain unsuitability.

[0003] Due to various problems with traditional impression taking, digital impression taking using scanning poles and intraoral scanners has begun. However, current digital scanning poles often suffer from installation problems due to overly large perforation designs or premature displacement of enlarged perforation designs, leading to gingival and bone obstruction and resulting in improper installation and restoration failure. Furthermore, current digital implant positioning scanning poles are prone to angular positioning errors. Some digital scanning poles have screws that separate from the scanning pole, while others have added threads at the interface to prevent screws from falling out, but these still have shortcomings. Separated screws are easily lost and inconvenient to use; the interface threads still have the problem of unscrewing during ultrasonic cleaning, and the thinner screw shafts pose a risk of breakage, increasing clinical safety risks. Moreover, current scanning poles require scanning the implant perforation cuff first, and then scanning the scanning pole itself; this results in long scanning times, and the cuff rebounds, increasing patient discomfort. Therefore, improvements are needed to address these issues. Utility Model Content

[0008] Preferably, a circular groove is provided in the middle of the inner wall of the cylindrical hole of the positioning seat, and an elastic steel wire is installed in the circular groove.

[0009] Preferably, the correction seat extends upward in a conical shape.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example: See Figure 1-5 This utility model discloses a screw-proof and angle-identifying implant restoration scanning rod, including an interface seat 1, a gingival seat 2 connected to the upper end of the interface seat 1, and a positioning seat 3 provided at the upper end of the gingival seat 2. The interface seat 1 facilitates matching with the implant and identification according to the implant model, making placement smoother and easier to identify. The gingival seat 2 allows for a direct view of the distance between the dividing line and the implant when taking X-rays, and also ensures that the scanning rod has sufficient strength and is not easily deformed. The positioning seat 3 facilitates the calibration of the implant horizontal angle. The interface seat 1 and the gingival seat 2 are provided with an interface Mohs cone angle, and a correction seat 4 is installed between the gingival seat 2 and the positioning seat 3. The correction seat 4 facilitates the calculation and correction of the vertical angle of implant positioning.

[0021] In this utility model, the interface seat 1 has a central hole through its middle, and the through seat 2, positioning seat 3, and correction seat 4 have cylindrical holes through their middle sections. The central hole and the cylindrical hole are connected at the Morse taper angle of the interface and are conical. The central hole and the cylindrical hole facilitate the installation of screws. The cylindrical hole of the positioning seat 3 has a circular groove in the middle of its inner wall, and an elastic steel wire 5 is installed in the circular groove. The circular groove facilitates the installation of the elastic steel wire 5 and helps to prevent the screw from falling out, thus achieving the effect of preventing loss. The correction seat 4 extends upward in a conical shape. The top surface of the positioning seat 3 is a regular hexagon, one of which is not flat, leaving a cylindrical body area. The side length of the regular hexagon is greater than the diameter of the cylinder, and the front face of the positioning seat 3 is lower than the other four faces. The five faces and the positioning seat 3 can be used for computer data positioning and recognition, making computer recognition simpler, easier, and less prone to errors.

[0022] Working Principle: In the use of this invention, during implant restoration, the patient's healing abutment is first removed. Then, the central and cylindrical holes of the interface seat 1, transgingival seat 2, positioning seat 3, and correction seat 4 are screwed into the notch. At this point, a gap is visible between the gingival cuff at the implant site and the transgingival seat 2 and positioning seat 3. After drying this area with the help of the dental chair's airflow, an intraoral scanner is quickly used for scanning. This scan acquires relevant data from the transgingival seat 2 and positioning seat 3, and accurately scans the shape of the gingival cuff, completing the data acquisition. The acquired data is then input into a computer system. This system uses the five marking planes on the upper part of the positioning seat 3, the cylindrical body retention area on the positioning seat 3, and the top positioning structure to determine the depth and horizontal angle of the implant. Simultaneously, the vertical angle of the implant positioning is calculated and corrected using the correction seat 4, thereby achieving precise implant positioning and providing accurate data support and reliable technical assurance for subsequent implant restoration.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
