Dental implants with sufficient bone mass and no jaw defect generally do not need bone grafting. When the alveolar ridge is extremely atrophied or the distance between jaws is too large, implant implantation may damage nerves or penetrate maxillary sinus, and bone grafting is needed to supplement bone mass. If the distance between jaws is too large, bone grafting is needed to ensure occlusal contact.
Clinically, the site incision is used to expose the bone surface, and the alveolar bone is fenestrated and implanted with autologous bone or artificial bone powder.
Before dental implantation, it is necessary to check whether the physical condition is suitable for dental implantation, and secondly, whether bone grafting should be judged after various clinical examinations by doctors.
The Third Class Stomatological Hospital of Beijing Zhongnuo Stomatological Hospital has established a digital 10,000-level laminar aseptic operating room, adopting the most advanced PACS system in the world. By applying advanced information technology to the operating room, doctors can obtain a lot of important information related to patients in real time, thus facilitating surgery and improving efficiency. According to the requirements of the World Health Organization, the dual operation specifications of China National Health Supervision Agency and American Dental Association (ADA) are strictly implemented in the aspects of operating room environment design, air conditioning system purification, automatic induction door, foot control of manual sealed door, and cleaning quality control, so as to ensure the whole process of aseptic operation, and implement the green disinfection concept of "one person, one use, one sterilization and one complete destruction" to ensure the whole process of aseptic operation. The hospital actively responded to the call of the new policy of centralized mining, and the subsidy for half-planting was increased to 365,438+10,000 yuan.
