As a specific professional ethics,medical ethics regards to the behavioral principles for medical staff,and moreover,the important qualifications of military medical trainees.Aimed to the cultivation of medical ethics among military medical trainees,this thesis raises four approaches including strengthening medical ethics education and enhancing recognition of medical ethics,emphasizing atmosphere cultivation,self-conscious medical practice to cultivate medical ethics qualification,and stressing self-cultivation to strengthen one′s conscience of medical ethics,to improve the direction,scientific features,and effectiveness of medical ethics cultivation.

The tensional relationship between doctors and patients caused by medical ethics and medical ethos is becoming a hot spot at present.It's of great significance to reduce the contradictions between the medical staff and the patients and construct a harmonious doctor-patient relationship by strengthening the construction of medical ethics and medical ethos and improving the professional quality of medical staff.

Objective : To investigate the application of digital immediate implant and angle screw channel abutment in the aesthetic area and the related influencing factors by reviewing the data of one case of immediate implant repair of the upper anterior teeth and related literature. Methods: One case of refractory chronic apicitis of the upper anterior teeth involved immediate implantation after extraction. The digital information of the patient was obtained by CBCT and intraoral scanning. According to the information from the patients, a preoperative evaluation was performed; a treatment scheme was formulated; a minimally invasive extraction was performed; implants were placed under a digital guide plate; and temporary restoration was immediately performed. Six months after the operation, the patients underwent individualized mold removal, and angle screw channel fixation was completed. We observed the cosmetic effects and soft and hard tissue and gingival contour maintenance effects after restoration and reexamined the patients 6 months after restoration. In addition, the relevant literature was reviewed. Results : The height of the gingival margin and gingival papilla and gingival contour of this patient were well maintained. The red and white aesthetic effect was good. There was no redness or swelling of the gingiva nor obvious changes in the soft and hard tissues around the implant 6 months after restoration, and the patient was satisfied. The results in the literature review show that a preoperative design based on CBCT and intraoral scanning data combined with digital software and a whole digital guide plate make the procedure more accurate and safer. These factors can not only avoid important anatomical structures and serious surgical complications but can also result in implantation in the best three-dimensional position. In addition, the application of digital impression technology and CAD/CAM increases the efficiency, speed, accuracy, simplicity, and comfort of oral impressions and the construction of temporary and final prostheses more precise and faster, greatly improving clinical efficiency. Conclusion Digital immediate implant and angle screw channel abutment is a good method to restore the aesthetics and function of missing teeth and to avoid the complications caused by adhesive residue.
