AI Technical Summary
Technical Problem
Existing orthodontic hooks can easily cause the rubber ring to fall off when the patient speaks or moves his mouth, and the hook design may irritate the patient's tongue or buccal mucosa.
Method used
An orthodontic hook including a bottom pad and a hook body is designed. The hook body has a cantilever beam and groove structure. The groove gradually narrows from the opening and widens in the middle, ensuring that the rubber ring is not easy to fall off under multi-directional traction, while reducing stimulation to soft tissue.
Benefits of technology
Effectively prevent the rubber ring from falling off when talking or moving the mouth, and reduce irritation to the tongue or buccal mucosa, improving the stability of the hook and patient comfort.

Abstract
An orthodontic hook includes a hook body and a base pad connectable to a tooth surface, the hook body extending through a connection portion projecting from the base pad to a cantilever portion forming a cantilever beam above the base pad, thereby forming a groove within the hook, a first end of the end portion being a maximum extension point along the cantilever portion, a second end of the end portion being a maximum extension point along the cantilever portion, and a third end of the end portion being a maximum extension point along the cantilever portion. The first tail end of the tail end part is closest to the bottom pad, the second tail end of the tail end part is closest to the bottom pad, a groove opening is formed between the first tail end and the bottom pad, a groove narrowing area is formed between the second tail end and the bottom pad, and the groove continuously narrows from the groove opening to the groove narrowing area and continuously widens from the groove narrowing area to the center of the groove. And the fifth width W5 of the groove narrowing area is less than 1.0 mm. Another feature is that the tip portion forms a protrusion with the second tip as a top end, the protrusion continuously decreasing in a direction toward the second tip, and a distance D9 between the second tip and a top surface of the tip portion is at least 2.4 times a distance D5 between the first tip and the top surface of the tip portion.
