Description

Bone regeneration titanium film for dental implantation

Technical Field

The utility model relates to the technical field of dental medical equipment, in particular to a bone regeneration titanium film for dental implantation.

Background

Dental implantation is one of the important surgical methods of the current dental restoration, and the main reason for the failure of dental implantation is that the bone mass of the jaw bone of a patient is insufficient, so that the implanted dental implant is loosened and fails. The proper horizontal and vertical direction of patient's jaw promotes patient's bone volume, increases dental implant's firmness, is the most crucial factor of preventing dental implantation failure.

The bone induction regeneration technology is clinically introduced into the field of dental implantation, and the principle of the technology is that a bone regeneration film is pasted on a part needing bone mass lifting to form a certain cavity, and artificial bone powder or autologous bone fragments are filled to induce the artificial bone powder to form bone. Whether the bone regeneration membrane can provide a stable cavity and cannot expose infection is a key factor influencing the osteogenesis effect.

Currently, the guided bone regeneration membranes commonly used in clinic are divided into two major types, i.e., absorbable membranes and non-absorbable membranes. The absorbable guide bone regeneration membrane is mostly designed into a double-layer membrane form, such as a Bio-Gide collagen membrane which is a product on the market and a tissue regeneration membrane provided by a patent CN 104474589A, wherein one layer is a compact layer and plays a role of a cell barrier and prevents soft tissue cells from growing into a bone defect area; the other layer is a loose layer which can induce new cells to grow into the loose layer and can be used as a support for cell growth to promote bone tissue regeneration. However, for the dental implant bone lifting operation, artificial bone powder is often required to be filled to induce bone tissue regeneration, the support property of an absorbable membrane is insufficient, the absorbable membrane is easy to collapse, a stable cavity cannot be formed, and the absorbable membrane cannot play a supporting role; in addition, once the absorbable membrane is degraded too early, the absorbable membrane cannot play a biological barrier role, muscle fibrous tissues grow into the artificial bone powder, so that cancellous bone is easily formed, compact cortical bone tissues cannot be formed, and the implant loosening failure is caused; absorbable membranes also have surgical risks of being unable to fix, causing displacement of the membrane, and the like.

Non-absorbable bone regeneration membranes, such as e-PTFE (expanded polytetrafluoroethylene, Expamded PTFE, e-PTFE) membranes, are also not sufficiently supportive and tend to collapse; the e-PTFE membrane limits the growth of soft tissues to a bone defect area, simultaneously limits the blood supply and protection of the soft tissues to a wound area, is often accompanied by the risks of slow healing of postoperative wounds and even cracking, and the risks of exposure of a regeneration membrane and postoperative infection caused by the cracking of the wounds are also accompanied.

The titanium membrane can effectually provide the support nature, but, the titanium membrane that uses clinically, thickness is thicker, is difficult to prune, is difficult to cause the wound to sew up the difficulty according to the form shaping of patient's jaw easily, leads to wound fracture, titanium membrane to expose etc. and leads to bone to promote the operation failure. Patent CN 106937896 a provides a titanium metal mesh, which is formed by pressing and designing fine titanium wires, but the technical process is complex, a large number of specifications and models need to be prefabricated, and the barrier function of the metal mesh needs to be further verified.
