Embodiment Construction

[0027] Hereinafter, the technology of the present application will be described in detail in combination with specific implementation manners. It should be understood that the following specific embodiments are only used to help those skilled in the art understand the present application, rather than limiting the present application.

[0028] In this embodiment, a barrier membrane is provided for use in guided bone regeneration techniques. Such as Figure 1A and Figure 1B As shown, the barrier film 1 includes two first absorbable films 11 and a support layer 12 sandwiched between the two first absorbable films 11, the support layer 12 includes at least one support member, The support is made of magnesium alloy.

[0029] Those skilled in the art can understand that the support layer 12 is not an actual layer, but a virtual layer composed of one or more supports arranged on the same layer, and the support layer 12 is defined in this application. Layer 12 is for expressing th...

Abstract

The present application relates to a barrier membrane for guiding bone regeneration technology. The barrier membrane comprises two layers of first absorbable films and a supporting layer clamped between the two layers of first absorbable films, the supporting layer comprises at least one supporting piece, and the supporting piece is made of magnesium alloy.

Description

technical field [0001] The present application relates to the technical field of biomaterials, in particular to a barrier film applied to guided bone regeneration technology. Background technique [0002] In recent years, the aging of the population, the gradual complexity of trauma types, and the rejuvenation of periodontal diseases have led to a sharp increase in the incidence of periodontal bone defects, posing severe challenges to the repair of periodontal bone tissue. Guided bone regeneration (GBR) technology is an important method developed in recent years to reconstruct alveolar bone and treat bone defects around implants. This process utilizes a barrier membrane to block rapidly proliferating epithelium and connective tissue, providing sufficient time and space for bone repair. [0003] In general, the barrier membranes used in GBR can be roughly divided into two categories: nonabsorbable membranes and bioabsorbable membranes. Non-resorbable membranes include expan...
