Description
Technical Field
The utility model belongs to the field of digital restoration and personalized restoration of dental edentulous implants, and particularly relates to a scanning rod for dental implant restoration.
Background
At present, the accuracy of intraoral scanning in dentistry cannot reach the accuracy in the industrial field, and the accurate coordinates of an X axis, a Y axis and a Z axis in accurate 3D data are required to be obtained and have larger errors; therefore, data docking is carried out by combining with a mature scanning technology in the industrial field, and accurate position coordinates of the implant are finally obtained for repairing.
The reason why the dental restoration cannot be independently completed using the industrial scanning technique with higher precision is that the industrial scanning has no way of completely obtaining the function of detailed information in the dental mouth. The reason for combining the industrial scanning technology is that more intraorally identifiable markers are scanned to obtain more operation parameters, so that the proof transformation process of computer software is more accurate, and more perfect automatic adjustment can be performed after dental data and industrial data are combined, so that a more appropriate prosthesis can be made. Specifically, although the dental scan is stable when acquiring coordinate data of the mesial-distal and buccal sides (labial side) and the lingual side (palatal side), a large error still exists in acquiring occlusion data, so that an error is increased when acquiring intraoral information of an edentulous jaw, and the reason is that a scanned object is insufficient in area due to the fact that a marker of a complete tooth is not used as a reference, and when computer software performs evidence-taking transformation operation, the acquired intraoral information of a patient is inaccurate due to a relatively thin comparison parameter.
SUMMERY OF THE UTILITY MODEL
In order to more accurately obtain information in an edentulous jaw of a patient, it is an object of the present invention to provide a scanning bar for dental implant restoration.
The purpose of the utility model is realized by the following technical scheme:

Wherein: the surface of the representing point block facing to the maxillofacial side and/or the labial-buccal side is provided with representing points.
The fixed column is of a hollow structure, a through hole is formed in the fixed column along the height direction, a screw is arranged in the through hole, and the whole scanning rod is fixed on an implant in the oral cavity of a patient or a printed oral cavity model through the screw.
The connecting rod is in the shape of a dental arch, the end face of the connecting rod is square, and the connecting rod of the scanning rod is in adjacent connection with the scanning rod in a cold welding or bonding mode after the overlapping part is cut off, so that a scanning rod connecting bridge body is formed.

2. The connecting rod of the utility model is in a tooth-arch shape, so that the connecting rod can be conveniently fixed with the connecting rod of the adjacent scanning rod, the square end surface design is convenient for having enough supporting force after being fixed, the fixed bridge of the scanning rod after being fixed is not deformed, the original record in the mouth of a patient can be better kept, an opening transfer rod and a temporary repair reinforcing rod can be replaced, and the time cost of a doctor can be saved when the scanning rod is cut off and used.
3. The length of the connecting rod on the required scanning rod can be cut off at will according to the specific situation in the patient's mouth to be fixedly connected with the adjacent scanning rod, and the connecting mode can adopt fixing modes such as cold welding or resin bonding; the number of the connected scanning rods can be four or six, and the group of the connected scanning rods and the bridge body become standard reference objects for later 3D digital detection, so that verification in the mouth of a patient can be replaced.
4. Because the scan rod attachment bridge maintains the original patient intraoral registration, intraoral data is obtained even when scanning is performed extraoral, which in turn adds more repair options to the design end personnel.
