Biological gel implant for maxillary sinus and preparation method of biological gel implant

Abstract

The invention relates to a biological gel implant for maxillary sinus and a preparation method of the biological gel implant. A porous surface structure and an internal hollow structure are manufactured by adopting a 3D printing technology combined with a CNC (Computer Numerical Control) method, wherein a lot of biological gel with osteoinductive factors is stored in the porous surface structure and the internal hollow structure; the biological gel implant comprises an implant section, a drill base, a center screw, biological gel and an aseptic packaging bottle; the top end of the implant section is connected with the drill base by virtue of screws; an outside cap is arranged at the top of the implant section; the neck of the implant section is provided with micro threads; the lower part of the implant section is of a porous surface structure and an internal hollow structure; a texture surface is formed in the hole wall; the porous structure is communicated with the internal hollow structure; a lot of biological gel with osteoinductive factors can be stored; and the concentration and release time of the biological gel are much superior to those of a biological coating implant at present. The biological gel implant has a skeleton-like hollow structure capable of inducing bone tissues to actively grow into the implant, the new bone fusion area and bone-formation strength of the implant can be greatly increased, and the biological gel implant is suitable for a maxillary sinus implant surgery under the condition of osteoporosis.

Description

technical field [0001] The invention relates to a dental implant, in particular to a dental implant with an osteoinductive factor gel, a porous surface and a hollow interior structure for solving the condition of maxillary sinus osteoporosis and a preparation method thereof, belonging to the field of oral dental implants. Background technique [0002] In the maxillary sinus region, the sinus cavity itself is the main structure, and the bone quantity and quality of the sinus floor are generally not good. The maxillary sinus floor followed by tooth loss, the alveolar process and the base of the alveolar bone were severely absorbed or completely absorbed, and the sinus floor decreased accordingly. In severe cases, it could become the same level as the remaining alveolar ridge, resulting in severe maxillary atrophy. Since the world's first dental implant was carried out in 1965, maxillary sinus implants have been excluded from the strict indications formulated by the founder Pro...
