Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oral implantation, in particular to a jaw bone supporting implant system for edentulous jaw. BACKGROUND

[0002] In the existing dental implant technology, the implantation of the implant requires the alveolar bone to have a certain width and height. Generally, the width of the alveolar bone needs to be greater than 5-7mm, and the height of the alveolar bone needs to be not less than 6-10mm. Under such conditions, through the positioning and reaming of the implant reamer in the alveolar bone, a matching implant (cylindrical or conical) is implanted into the alveolar bone, and after a healing period of 1.5 to 6 months, the crown is repaired.

[0003] However, when the maxillary dentition is missing, a part of the patients cannot be repaired by removable denture or implantation. For example, when the alveolar bone of the maxillary bone is absorbed, the width of the alveolar bone is less than 5mm, and the height of the alveolar bone is less than 6mm, it is usually necessary to use bone augmentation technology or use bone splitting technology + bone augmentation technology. Although these dental implant technologies can increase the bone mass, they also have the following problems:

[0004] First, the bone augmentation technology needs to wait for about 6 months after the operation, which increases the repair time and the treatment cycle; second, the reaction after the bone augmentation is large, and the risk of complications is high; third, the treatment cost of the patient is increased; fourth, some patients refuse to perform the bone augmentation technology or cannot perform the bone augmentation technology.
