Description

Technical Field

[0001] The utility model relates to the field of stomatology tools, in particular to an oral digital implant guide with a positioning function. Background Art

[0002] A dental implant guide is a tool used to assist doctors in accurately finding the depth and direction of an implant. During oral implant surgery, a dental implant guide can accurately guide implant positioning and hole preparation, avoiding complications caused by implant site deviation due to poor vision and angle of view, and reducing the difficulty of surgery. In actual operations, computers are usually used for assisted design and manufacturing, that is, a three-dimensional model of the jaw is reconstructed through the patient's maxillofacial CT image before the dental implant surgery, and the appropriate implant type is selected based on the image data of the jaw. In combination with the implant's teeth, bone mass and other information, a digital oral implant guide is selected and designed, and ultimately an overall implant surgery plan is obtained. In this way, doctors can use oral digital implant guides to achieve safe and accurate implant surgery, which can prevent damage to the inferior alveolar nerve, perforate the maxillary sinus floor, and ensure that the implant is placed in an ideal position.

[0003] An oral digital implant guide generally includes a guide body and a medical rubber strip arranged inside the guide body. A fitting groove adapted to the alveolar bone is opened inside the guide body, but the guide body and the medical rubber strip are generally connected in an integrated manner. For patients at different treatment stages, if the medical rubber strip is damaged or worn during use, the implant guide body needs to be replaced. In addition, the integrated design is not convenient for replacing the hardness, thickness or shape of the medical rubber strip according to individual differences of patients, and cannot adapt well to different gum conditions and implant needs.
