Embodiment Construction

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts all involve the protection scope of the present invention.

[0050] like Figure 1 ~ Figure 3 As shown, this embodiment proposes a bone hybrid support type external distraction osteogenesis device in the mouth, including:

[0051] Retaining nail 1, described retaining nail 1 is used for being fixed on the upper end cortical bone;

[0052] 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 retaining nail 1 and the traction nail 2 are connected by means of t...

Abstract

The invention relates to the technical field of oral maxillofacial surgery and orthodontics, and provides a dental bone mixed supporting type external intraoral distraction osteogenesis device and a using method. The dental bone mixed supporting type external intraoral distraction osteogenesis device comprises a retention nail, a traction nail and a traction piece, the retention nail is used for being fixed to the upper end of bone cortex, the traction nail is used for being fixed to a dental surface to be adjusted, the retention nail and the traction nail are connected through the traction piece, and the traction piece is used for providing elastic force for the retention nail to be away from the traction nail. By means of the technical scheme of the dental bone mixed supporting type external intraoral distraction osteogenesis device, the problem that in the prior art, distraction osteogenesis is difficult to operate 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 osteogenerator and a use method thereof. Background technique [0002] Dental ankylosis is the most common complication leading to maxillofacial developmental deformities after dental trauma in children and adolescents. Distraction osteogenesis is one of the methods to treat such developmental deformities. Distraction osteogenesis is an endogenous tissue engineering technique. When applied to tooth-bones adhesion, it is necessary to perform a square osteotomy on the adherent tooth, remove the cortical bone around the adhesion area, and place distraction osteogenesis devices on both sides of the bone section. , through the external force generated by it, the incisional bone gap is continuously widened, and the potential of tissue regeneration is stimulated, new bone tissue is continuously formed in...
