Stitching-free isolating membrane for repairing bone defects and preparation method of stitching-free isolating membrane

Abstract

The invention discloses a stitching-free isolating membrane for repairing bone defects. The isolating membrane is rectangular or square, wherein a plurality of miniature through holes with the diameter D1 being 10-20 [mu] m are formed in the isolating membrane, a plurality of conical bulges are arranged on the upper surface of the isolating membrane, and the distance H2 between the sharp ends of the conical bulges and the upper surface of the isolating membrane is 500-1000 [mu] m. The stitching-free isolating membrane for repairing the bone defects provided by the invention is used when the various bone defects are repaired or the bone amount is insufficient; during the operation, the isolating membrane is directly placed at the affected part, after the soft tissue contacts the isolating membrane, the conical bulges on the isolating membrane stab the soft tissue, so that the soft tissue is aligned easily and fixed easily, and the stitching is not needed, therefore, extremely great convenience is brought to a surgery operator; and meanwhile, the pain of the patient is alleviated. The isolating membrane is good in flexibility; the experimental result shows that the degradation absorption is good, the wound healing is good, the isolation between the soft tissue and the bone is good, the growth condition of the newly growing bone tissue is good, etc.

Description

technical field [0001] The invention relates to an isolation membrane used in dental operations, which is a seam-free isolation membrane for bone defect repair. Background technique [0002] In orthopedic surgery, there are often patients who require repair due to bone defects. For example, in some patients, the alveolar bone volume is insufficient or the alveolar bone defect forms a cavity. This situation will directly affect the success rate of dental implant surgery, often resulting in weak teeth after dental implantation, which seriously affects the quality of life of patients. . In order to solve the above problems, the current method is to cut soft tissues such as gingiva and fill them with bone powder, then cover the surface of the bone powder with a film to isolate the bone tissue from the soft tissue, and finally suture the soft tissue on the film. The disadvantage of this method is that the space in the gingival area inside the oral cavity is small, which increas...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that the space of the gums inside the oral cavity is small, which increases the difficulty of the suturing operation and brings more pain to the patient.
