However, for a large part of patients with tooth loss, the bone absorption of the tooth loss part is serious during the treatment, and the implantation can not be completed through the self bone mass, the bone mass of the implantation area needs to be increased through a Guided Bone Regeneration (GBR) technology, and particularly for the alveolar bone vertical bone augmentation surgery, two surgery methods are generally adopted at present: firstly, titanium mesh implantation and implant tooth restoration operations are carried out in stages, the gum in the tooth missing area is cut through the operations, alveolar bones are exposed, bone powder is filled in the bone quantity insufficient position, the artificial periosteum is used for wrapping after the operation is finished, and the standardized finished titanium film is provided at the outermost layer to protect and fix the appearance of the artificial periosteum. And after the alveolar bone tissue grows plump, taking out the titanium film, redesigning the dental implant operation scheme and the operation guide plate, and performing secondary dental implant restoration operation on the edentulous position. And secondly, completing immediate implantation repair operation under the condition of insufficient bone mass in the tooth-deficient area, implanting a corresponding implant after turning over the flap according to an implantation operation scheme, filling bone powder around the implant, wrapping the implant by using an artificial periosteum, providing a finished titanium membrane at the outermost layer to protect and fix the periosteum, and taking out the titanium membrane after the bone growth of the part is full.

The common problem existing in the two operation modes of the vertical bone increment in the edentulous area is that when a clinician carries out the operation, because only a standardized finished titanium film (the shape is subjected to standard fixation) is needed at present, the titanium film with more appropriate parameters such as the shape size and the like needs to be selected, and the selected titanium film is subjected to fine adjustment on the structure shape according to the actual shape of the alveolar bone filled with bone powder in the operation, so that the titanium film can be tightly attached to the alveolar bone. The most key problem existing at present is that a standardized titanium film does not have a fixed supporting point, the titanium film in place completely depends on the experience of a clinician in the operation, the shape of the alveolar bone filled with bone powder is observed while the shape of the alveolar bone is observed, meanwhile, the structural shape of the titanium film is roughly finely adjusted by hands outside an operation area according to the shape (the titanium film is visually observed to be attached to the alveolar bone approximately), and then the titanium film is implanted into a corresponding position.
