From January 2016 to [Abstract] ObjectiveTo investigate the effect of applying bone augmentation technology in the restoration of maxillary anterior tooth loss. MethodsA total of 40 implants were selected from the 24 patients with maxillary anterior tooth loss and restoration who came to our hospital to be treated with bone augmentation techniques such as bone splitting, bone extrusion, maxillary nasal floor lifting bone grafting and guided bone regeneration, and the bone defect healing and tissue healing of the groomed patients were observed, and the surrounding osseointegration and implant integration were observed. Results A total of 36 implants had excellent osseointegration and 4 implants were unsatisfactory, with an excellent rate of 90.00%. Conclusion The bone augmentation technique is applied to the treatment of bone injury around the missing implant of maxillary anterior teeth, so that the implant can obtain better osseointegration, and the implant can be well covered after restoration, thereby improving the success rate of implant restoration.

Clinically, the loss of maxillary anterior teeth can be caused by loosening of traumatic root trauma, repair failure of residual root and refractory apical lesions, and the coverage relationship of maxillary anterior teeth has high requirements for the direction and position of the implant. Bone augmentation techniques mainly refer to the use of alternative materials such as bone meal and periosteum to increase bone height and width, mainly when the bone height and width are not high enough to implant or the implant is sufficient, or the remaining bone on the labial and buccal sides is thin. Implantation of bone substitutes requires osteogenesis time, and secondly, due to individual differences, there may also be row reactions or prolonged osteogenesis concaves. The effect of bone augmentation technique in patients with maxillary anterior tooth loss is studied.
1. Information and Methods
1.1 Basic Data
From January 2016 to the present, 24 patients with missing maxillary anterior teeth were selected from January 2016 to the present, with a total of 40 implants. There were 10 female patients and 14 male patients, with the youngest age of 20 years and the oldest age of 58 years, with an average age of (39.48 ± 2.15) years. Among the 24 patients, 8 had insufficient height, 6 had insufficient alveolar bone width, and 10 had both.
1.2 Method Implant: ITI. Dentium, BiOOss, bone meal, periosteum, etc. Implant equipment: W&H implant machine, CAMLCG implant equipment box and bone extrusion tools.
Before the operation, the patient was evaluated by oral CBCT preoperative bone mass, and the patient's previous medical history and contraindications to surgery were inquired about. CBCT can measure the bone density of the jaw, measure the bone area of the alveolar bone, and directly quantify the three-dimensional area of the bone defect, which can display the structure of the hard-bone plate in the near and far, and clarify the damage of the bone wall and accurately display the bone defect. For bone height, width (alveolar ridge thin) is insufficient or there is bone fenestration after implantation, the patient needs to be treated with autologous bone + GBR, if the patient's bone defect is serious, the implant should be implanted after the bone material is osteogenic, if only part of the deficiency can be implanted after the implant on the sealing screw and then GBR or autologous bone implantation + GBR, close coincidence, the general osteogenic time is about 6 months, and X examination is performed after 6 months to see the osteogenic condition to measure the stability of the implant. Patients need to be suitable for bone replacement materials to fuse with the original bone as soon as possible to improve the success rate of bone grafting. GBR mainly uses the characteristics of the barrier membrane to organize the fibroblasts of the surrounding soft tissues, and the cells at the bone surface will proliferate, so as to achieve the effect of targeted repair and regeneration. For patients with bone defects, bone-guided regeneration is used, and implants of appropriate diameter and length should be selected according to the design for implantation, and the mucoperiosteal flap can be used to suture the wound tightly under the action of cushioning tension, and the patient is treated with antibiotics, dexamethasone, etc. Bone augmentation technique is a less harmful surgery, and bone augmentation treatment is performed from autologous bone, and the effect of autologous bone treatment is remarkable. After surgery, the patient should be given antibiotics to prevent infection and treated with analgesic drugs appropriately. Autologous bone grafting does not cause rejection, aids in bone healing, and accelerates osteogenesis. Allogeneic bone grafting can cause rejection, and autologous bone and allogeneic bone integration can be used clinically, resulting in increased bone mass. Because bone resorption occurs in grafted bone, appropriate over-grafting is of some significance.
1.3 Judgment Indicators
Before surgery, oral CBCT was performed on patients with maxillary anterior tooth loss and restoration, and the alveolar bone mass in the edentulous area was evaluated in three dimensions, mainly including height and width. After bone grafting, the patient's teeth returned to normal function and had a high strength, demonstrating the effect of bone augmentation.
2 Results
Among the 24 patients with maxillary anterior tooth loss, there were 40 implants, 36 implants with excellent osseointegration and 4 unsatisfactory osseointegration, with an excellent rate of 90.00%.
3 Discussion
The rational and scientific application of bone augmentation technology can also regenerate the bone defects around the implant in the maxillary anterior tooth area, and its binding rate is high, so as to obtain significant implant restoration effects. This group was treated with bone augmentation techniques, which mainly showed tissue regeneration through barrier membrane properties. Its purpose is to show the regeneration of tissues through the characteristics of the barrier membrane, and to organize the fibroblasts released from the surrounding soft tissues through the barrier membrane, so that the bone surface bone cells can fully proliferate and rebuild. The main functions are (1) tent function: (2) cell shielding effect; @支架作用; (4) Stabilization. The use of titanium film treatment has better compatibility and lower price, which can meet the tent effect, cell shielding, etc., and can be used as the preferred material for bone-guided regeneration technology4. Its non-absorbable membrane is not degradable in vivo and requires surgical removal. It is very easy to rupture the tissue flap, and the tissue membrane is exposed as soon as possible, which affects the growth of new bone. Insufficient bone mass can lead to peri-implant bone defects, which can affect the stability of the implant. In summary, bone augmentation technology can be used to treat patients with maxillary anterior tooth loss, and the implant and bone integration effect is better, so as to meet the needs of patients and improve the success rate of restoration.
