AI Technical Summary
In existing technologies, viscous bone fillers are prone to falling off when applied to missing teeth, and PRF clear fluid is squeezed out, affecting the restorative effect.
A dental restoration adhesive bone filler was designed, including a handle, a rotating sleeve, a receiving tube, a limiting post, and a gap sealing mechanism. The rotating sleeve controls the opening and closing of the discharge port of the receiving tube to achieve precise filling of adhesive bone.
This prevents the loss of viscous bone and the dripping of PRF solution, thus improving the repair effect.

With the development of social economy, more and more edentulous patients tend to use dental implants for edentulous repair. Edentulous repair is prepared by mixing PRF supernatant extracted from patient's own blood and tooth bone powder and filling in the patient's pressure groove. The existing method of using forceps to pick up the adhesive bone and fill it in the tooth loss place has the problem that the adhesive bone is easy to fall off. In addition, when the forceps pick up the adhesive bone, the PRF supernatant is easily squeezed out and dripped, which affects the repair effect. SUMMARY

[0005] The gap sealing mechanism is composed of a guide rod, a spring and a pad, the pad is provided as a semicircular ring structure matched with the semicircular arc-shaped groove, the pad is slidingly installed in the semicircular arc-shaped groove, the outer ends of the two guide rods are fixedly installed on the pad, the inner ends of the two guide rods are slidingly installed at the bottom of the semicircular arc-shaped groove, the spring is sleeved and installed on the guide rod, and under the action of the spring force, the outer end of the pad is always pressed on the rotating sleeve.
[0006] Further, the upper end outer surface of the rotating sleeve is provided with a mesh anti-slip pattern.
[0007] Further, the outer end of the handle is provided with a T-shaped groove, the upper end of the containing tube is provided as a T-shaped structure, the T-shaped structure is slidingly installed in the T-shaped groove, and the top of the containing tube is provided with a limiting bolt for pressing and fixing it on the handle.
[0008] Furthermore, a non-slip rubber sleeve is fixedly mounted on the handle.
[0009] Compared with the prior art, the benefits of the present invention are as follows: after the filler is placed against the patient's tooth that needs to be repaired, the rotating sleeve is rotated to open the first semicircular discharge port at the front end of the accommodating tube and then the viscous bone filling and repair is performed. After the repair is completed, the rotating sleeve is rotated to close the first semicircular discharge port at the front end of the accommodating tube, and then the filler is taken out of the patient's mouth, avoiding the problem of viscous bone falling off when clamped by tweezers, and also avoiding the problem of PRF clear liquid being squeezed out and dripping when clamped by tweezers.
