Embodiment Construction

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts are all related to the protection scope of the present invention.

[0050] like Figure 1 to Figure 3 As shown, this embodiment proposes a dental-bone hybrid support type external intraoral distraction osteogenesis device, including:

[0051] Retention nail 1, the retention nail 1 is used for fixing on the upper cortical bone;

[0052] a traction nail 2, the traction nail 2 is used to be fixed on the tooth surface to be adjusted;

[0053] A traction member 3, the retention nail 1 and the traction nail 2 are connected by means...

Abstract

The invention relates to the technical fields of oral and maxillofacial surgery and orthodontics, and proposes an externally placed intraoral distraction osteogenesis device supported by dental bone and a method for using the same, comprising a retention nail, a traction nail and a traction piece. It is used to be fixed on the upper end of cortical bone, the traction nail is used to be fixed on the tooth surface to be adjusted, the retention nail and the traction nail are connected by the traction member, and the traction member is used to provide the retention The elastic force of the pegs away from the traction pegs. Through the above technical solution, the problem of difficulty in the operation of distraction osteogenesis in the prior art is solved.

Description

technical field [0001] The invention relates to the technical fields of oral and maxillofacial surgery and orthodontics, in particular to an externally placed intraoral distraction osteogenesis device supported by dental bone and a method for using the same. Background technique [0002] Dental ankylosis is the most common complication of maxillofacial developmental deformity after dental trauma in children and adolescents. Distraction osteogenesis is one of the methods to treat this developmental deformity. Distraction osteogenesis is an endogenous tissue engineering technique. When applied to dental bone adhesion, it is necessary to perform square osteotomy on the adhered tooth, excise the bone cortex around the adhesion area, and place distraction osteogenesis devices on both sides of the bone section. , through the external force generated by the incision, the bone gap is continuously widened, and the potential of tissue regeneration is stimulated, new bone tissue is con...
