Description

Technical Field

[0001] This utility model relates to the field of dental implant technology, and in particular to a multifunctional healing scanning rod assembly. Background Technology

[0002] In the process of dental implant restoration, digital design has replaced the traditional wax-cast restoration process and has become the industry mainstream. The main process of digital design includes: In the first stage of treatment, the dental implant is inserted into the patient's alveolar bone, and the healing abutment is installed on the dental implant. During the healing process, the gingival wound is wrapped with the healing abutment to form a gingival cuff, ensuring that the dental implant restoration meets medical and aesthetic requirements. After the dental implant has completed osseointegration in the patient's mouth, the patient returns to the dental clinic for the second stage of treatment. An impression or intraoral scan is performed to obtain data on the teeth in the oral cavity. The healing abutment is removed, and a scanning rod is installed on the dental implant in the patient's mouth. An intraoral scanner is used to scan the scanning rod to obtain three-dimensional data of the patient's dentition. Alternatively, a transfer rod is installed on the dental implant in the patient's mouth. Through biting impression and plaster mold making, a scanning rod is installed on the plaster mold, and a scanning rod is used to scan to obtain three-dimensional data of the patient's dentition, thus realizing digital design.

[0003] In related technologies, although there are already healing abutment scanning rods that integrate the functions of healing abutment, transfer rod, and scanning rod, the scanning area of ​​the healing abutment scanning rod is exposed to the oral environment during treatment, which easily leads to plaque deposition. During the second stage of treatment, the alignment accuracy of the scanning rod is affected, which in turn affects the fabrication accuracy of the restoration, making frequent rework very likely.
