Description
Technical Field
[0001] The utility model relates to the technical field of dental scanning, in particular to a digital positioning scanning precision kit. Background Art
[0002] In oral restoration and implantation, especially in the case of edentulous jaws and extensive tooth defects, accurate digital scanning is crucial. Current scanning technologies mostly use cylindrical positioning rods, and their registration surfaces are generally designed on the side surfaces of the rods. This configuration works well when dealing with cases of having teeth or minor tooth defects, but in the case of a completely edentulous jaw or a large number of missing teeth, its effect is usually limited. The main reason is that the cylindrical positioning rod lacks sufficient structural complexity and cannot provide effective scanning reference points, thus affecting the progress and integrity of three-dimensional reconstruction.
[0003] Especially in the case of edentulous jaws, due to the lack of tooth structures to provide natural scanning references, standard scanning devices are difficult to anchor the necessary reference points, often resulting in insufficient data capture or large errors. In addition, many traditional scanning positioning devices are not equipped with auxiliary rods, further limiting the upgrade of scanning accuracy, because the auxiliary rods can provide additional landmark points and enhance the data capture and processing capabilities during the scanning process.
[0004] Therefore, a digital positioning scanning precision kit applicable to edentulous or continuous multiple tooth defects is needed to improve scanning accuracy and efficiency. Summary of the Utility Model
