Multi-angle rotating combination of dental implant wrench

This creation is about a dental implant wrench, especially a dental implant wrench that can be rotated in multiple angles.

Artificial dental implants have been used in oral therapy for many years, and due to the advancement of dental implant materials and implant technology, more and more patients choose implants to replace the previous fixed or movable dentures.

In the process of artificial implanting, the drill tool is used to gently drill the instrument up and down until the cortical bone is passed through the position where the denture is to be implanted. Next, a dental implant is screwed into the tibia of the patient's mouth to replace the extracted root, and abutment combined with the artificial crown is provided, and then the artificial crown is attached to the implant. The entire procedure of implanting the teeth can be completed physically. The conventional dental implant wrench has a main rod body and a ratchet head fixed to the main rod body. The ratchet head can mesh with the implant body and cooperate with the torque of the dental implant wrench to screw the implant body into the tibia.

In the above process, the insertion of the implant into the patient's mouth is an important step in the dental implant procedure, because the curvature of the dental bone in the oral cavity varies from person to person, and it is easy to shrink and form an arc-shaped lower line when the tooth is missing. If the implant is implanted in a position that is not perpendicular to the occlusal surface of the tooth, a deviation occurs, which causes difficulty in the subsequent installation of the artificial crown, and even causes the artificial crown to be skewed to cause the implant failure. In addition, due to the face problem of each person, the dental bone is not horizontal, but may be slightly inclined, so that the implanted teeth should be adjusted according to the bone when implanting the posterior row. So if you use The conventional dental implant wrench has a single angle because the ratchet head is fixed on the main rod body, so that the user must adjust the posture of the hand to adjust the implanted tooth body to be implanted in the correct position.
