1 psychological care. Psychological care for elderly patients and their families is an important part of successful operation. Due to the lack of knowledge and understanding of alveolar bone repair, the physiological function of the elderly is gradually declining, and their immunity and compensatory ability are reduced, and they are prone to anxiety, fear, tension, fear of pain and other adverse psychological States before operation. Nurses should actively and enthusiastically receive patients and give them comfort and encouragement. And introduce the necessity of surgery to patients and their families (if not, the teeth inserted in this operation can't eat, and eating hurts. You can eat peanuts if you have an operation. The prediction of operation process and effect is satisfactory. Encourage patients to cooperate with the operation, such as not shaking their heads or keeping their mouths shut at will. If you feel unwell, you can signal with your hand. You should have a good attitude to accept the operation. For example, a 74-year-old female outpatient with diabetes and hypertension was particularly nervous, lost her temper with her wife and refused to undergo surgery. After careful explanation, we took her blood pressure and told her that her condition was stable and she could operate. And the operation time is not long, it can be completed in ten minutes at most, and it will not bring you great pain. Under our psychological guidance, the patient's psychological state has changed, from fear of surgery to refusing to take the initiative to accept surgery. Two months after operation, the patient was very satisfied with the whole mouth.

2 preoperative preparation. ① Be familiar with the necessary routine examination results of patients and understand the general health status. Patients with diabetes, heart disease, hypertension and other systemic diseases are not suitable for surgery. And those who are too nervous to cooperate with the doctor. And do basic nursing for outpatients and pay attention to measuring blood pressure. It is observed that more than 50% of the elderly suffer from hypertension. ② Preparation of instruments and articles: In addition to the conventional surgical instrument set, other disinfection articles such as bone chisel, bone hammer, bone file, periosteum separator, bone rongeur and salivary aspirator should be prepared for future use.

Operation cooperation and nursing care

1 Adjust the chair position and light source according to the operation site. When the maxillary alveolar bone is repaired, the head position is slightly backward, so that the maxillary tooth surface forms an angle of 45 with the ground plane. When the mandibular alveolar bone is repaired, the mandibular tooth surface is parallel to the horizon, and the chair position is slightly lower, so that the operating area is the same height as the operator's elbow. It is suggested to make operators and patients feel comfortable as much as possible to reduce their mental and physical fatigue.

Because the elderly patients have weak physical function and reduced compensatory ability, they should pay attention to observation during operation and cooperate with doctors to deal with accidents in time to ensure the smooth completion of the operation.
