Medical degradable integrated membrane preparation method, integrated membrane and periodontal tissue regeneration method

The invention provides a preparation method of a medical degradable integrated membrane, the medical degradable integrated membrane and a periodontal tissue regeneration method. The preparation method of the medical degradable integrated membrane comprises the steps of powder preparation, sintering molding, processing molding, surface treatment and ultrasonic cleaning. According to the present invention, the degradable membrane having the porous structure and meeting the thickness requirement can be obtained, the strength of the membrane is high, such that the membrane can be sufficiently applied to the large-area alveolar bone absorption, the porous structure is simultaneously used for preventing the bone cement filled in the periodontal pocket from overflowing, the manufacturing cost is low, and the medical promotion and application are easily achieved. 本公开提供一种医用可降解一体膜制备方法、医用可降解一体膜及牙周组织再生方法，医用可降解一体膜制备方法包括粉末制备、烧结成型、加工成型、表面处理和超声波清洗。根据本公开，能够获得具有多孔结构的、满足厚度要求的可降解膜片，膜片的强度高，使其足够应用于大面积的牙槽骨吸收，多孔结构同时用于防止牙周袋内填充骨水泥溢出，制
