Methods Sixteen patients and 23 measured points were enrolled in this study. CBCT data immediately and 6 months after bone grafting were measured at crestal (CW), midway (MW), and basal (BW) levels and reconstructed for area measurement using a titanium screw as the reference plane. The exposure of titanium mesh or not had been evaluated. Results There were no statistical differences between the titanium mesh and onlay grafting, and measured levels at CW, MW, and BW, the exposed titanium mesh and not exposed one. The width absorption ratio of titanium mesh and onlay grafting group or at CW, MW, and BW were almost the same. The area of bone gained and absorption ratio were almost the same without statistical differences. However, the width absorption ratio of the exposed titanium mesh at CW, MW, and BW was significantly higher than the not exposed one. Thin biotype was a main factor in the exposure of titanium mesh. The exposed titanium mesh at the late phase can also achieve clinically accepted bone gain after certain anti-inflammatory treatments. Conclusion Ti-mesh with tenting screw technique and autologous bone graft can achieve clinically acceptable bone augmentation effect. However, the absorption ratio significantly increased if exposed.

Biological principle of emergence profile design of implant prosthesis Yang Yufei, Gu Xinhua Chinese Journal of Oral Implantology    2022, 27 (6): 352-357.   DOI: 10.12337/zgkqzzxzz.2022.12.005 Abstract （319）      PDF （1106KB）（786）       Knowledge map    Save The emergence profile design of the implant prosthesis will not only affect the aesthetic effect of the prosthesis, but also affect the health of the tissues around the implant. Good emergence profile design helps to form a perfect soft tissue barrier, prevent microbial invasion, protect surrounding soft and hard tissues, and avoid aesthetic and biological complications. On the basis of understanding the biological characteristics of the tissue around the implant and based on the patient's soft and hard tissue conditions, designing a reasonable implant placement position to protect the health of the tissue around the implant is crucial to the success of the implant and also a necessary factor for the design of the emergence profile.

Progress in evaluation methods of dental implant placement accuracy Su Tianyue, Teng Weiwei, Wang Qi, Shu Qianyi, Zhou Libo Chinese Journal of Oral Implantology    2022, 27 (4): 248-253.   DOI: 10.12337/zgkqzzxzz.2022.08.009 Abstract （346）      PDF （1171KB）（671）       Knowledge map    Save The application of digital technologies such as static guide, dynamic navigation and dental implant robot in the field of dental implant achieves the purpose of accurate implant placement. However, there is no unified standard for accurate recording and evaluation of dental implant sites, it is particularly important to select high-resolution postoperative evaluation methods to accurately reflect the accuracy of dental implants. At present, the commonly used instruments for assessment after dental implant surgery include CBCT, intraoral scanner, desktop optical scanner, and three-coordinate measuring instrument. In drilling experiments in other fields, calipers, plug gauges, digital measuring instruments such as three-coordinate measuring machine and laser tracker are also used for measurement, which can provide reference for the evaluation of the accuracy of dental implant implantation. In this paper, the principles, precision and characteristics of the accuracy evaluation methods involved in the drilling experiments of dental implants are reviewed, in order to provide a theoretical reference for the accuracy evaluation of dental implants in experiments and clinical practice.

Strategies for implant surface decontamination in therapy of peri-implantitis Yang Ting, Hu Wenjie Chinese Journal of Oral Implantology    2024, 29 (4): 385-390.   DOI: 10.12337/zgkqzzxzz.2024.08.015 Abstract （52）      PDF （1381KB）（66）       Knowledge map    Save Peri-implantitis is a biofilm-mediated pathological condition of peri-implant tissue, characterized by inflammation in peri-implant mucosa accompanied by progressive loss of supporting bone around dental implants. It is the main reason that affects the long-term result of dental implant restoration, which might eventually lead to implant failure. Implant surface decontamination is the key to the management of peri-implantitis. Non-surgical treatment and surgical treatment have both been used in clinical practice, but there is no gold standard protocol for implant decontamination. Therefore, it is of great significance to compare the characteristics of implants with and without peri-implantitis to understand the decontamination strategy for infected implant surfaces, which can provide a reference for clinicians in the decision-making when managing peri-implantitis.
