Technical Field

[0001] The utility model belongs to the technical field of oral restoration instruments, and in particular relates to a crown removal forceps for oral restoration. Background Art

[0002] Restorative dentistry primarily focuses on the treatment of damaged or missing teeth, using methods such as inlays, crowns, and dentures. It also includes the use of artificial prostheses to treat periodontal disease, temporomandibular joint disease, and maxillofacial tissue defects, such as bite splints, periodontal splints, prostheses, artificial eyes, ears, and noses. It is a key branch of dentistry, with implant restorations, adhesive restorations, and aesthetic restorations representing the fastest-growing areas in modern restorative dentistry, significantly enhancing the effectiveness and quality of restorative dentistry.

[0003] Crown removal forceps are a common tool for oral restoration. Their structure and operation method are roughly the same as those of conventional pliers. Medical personnel are required to operate the two handles to drive the pliers heads to clamp the crown for operation. However, the handle structure of existing crown removal forceps is simple. Due to the complex condition of the teeth inside the patient's mouth, after the operator inserts the crown removal forceps into the patient's mouth, the pliers handles are often not in the right direction, making it inconvenient for the operator to apply force, and the pliers handles may even slip, affecting the oral restoration operation.
