Technical Field

The invention relates to an ultrasonic system for alveolar bone reconstruction, and belongs to the field of artificial restoration of alveolar bones.

Background

Alveolar bone, also known as alveolar process, surrounds the jaw bone protrusion of the root of the tooth; the socket for accommodating teeth is called an alveolar socket, alveolar bones between two teeth are called alveolar spaces, and the interdental alveolar bones of a plurality of teeth are called interdental bones; the alveolar bone is the part of the lower edge of the maxilla and the upper edge of the mandible, which is embedded with the tooth root; the alveolar process parts of the upper and lower jawbones, which are inherent alveolar bones close to the inner walls of tooth roots and periodontal ligament, are a layer of compact bone with meshes and are attached with periodontal ligament fibers; alveolar bone is the most variable part in the skeleton system of the whole body, and the change can reflect the reconstruction process of bone tissues; it grows with the growth and eruption of teeth, and develops well due to physiological functional stimulation; after a tooth is lost, normal functional stimulation is lost, and disuse atrophy can be generated. Excessive irritation can also cause traumatic absorption.

When the human body is grown with age and the teeth fall off, the alveolar bone is prone to deform and the alveolar bone is prone to atrophy, and in this case, after the alveolar bone deforms or shrinks, the tooth can not be directly planted on the original alveolar bone, because the tooth is planted under the condition, secondary damage can be caused to the original shrunken alveolar bone, the matrix of the tooth is prone to fall off or collapse, therefore, after the alveolar bone shrinks, the alveolar bone needs to be rebuilt to thicken and shape the alveolar bone, the tooth can be planted after the tooth meets the conditions of the tooth planting, the existing alveolar bone repairing technology is prone to form and repair by adopting a titanium mesh which is prone to be fixed by screws, and in this way, the titanium mesh is prone to be taken out by secondary operations, and tapping and screwing processes of the screws cause multiple injuries to the fragile alveolar bone, and a patient causes secondary injuries, therefore, an alveolar bone repairing means which can not cause repeated operations and damage to the original alveolar bone is lacking in the market.
