A case of teeth extraction and immediate implants with the application of ridge splitting technique in anterior mandibular alveolar ridge Shi Wen, Wang Miaozhen, Liu Feng Chinese Journal of Oral Implantology    2022, 27 (6): 340-345.   DOI: 10.12337/zgkqzzxzz.2022.12.003 Abstract （419）      PDF （1500KB）（553）       Knowledge map    Save In the anterior mandibular aesthetic area, there is usually sufficient bone in the vertical direction and insufficient bone in the buccolingual and horizontal direction. In this paper, we present a case of a patient with multiple mandibular incisors to be extracted due to chronic periodontitis, in which the ridge splitting was applied to the anterior mandibular alveolar ridge with teeth extraction and immediate implant placement simultaneously. Teeth extraction, ridge splitting and implant placement were performed at the same time, and the second surgery was performed 6 months after the operation, and temporary restoration and permanent restoration were completed by digital technology 7 and 8 months after the first surgery.Teeth extraction and immediate implant placement with ridge splitting procedure allows the clinician to effectively augment the horizontal bone, improve implant success rate, reduce the number of operations and avoid a second operative area. The simultaneous application of ridge splitting technique with tooth extraction and implant placement with proper indications and operation details may have certain advantages over other implant options.

New clinical operation of comprehensive sequential treatment for immediate implant placement in the posterior mandibular region Zhou Qin, Zhao Zhengyi, Zou Duohong, Yang Chi, Zhang Zhiyuan Chinese Journal of Oral Implantology    2022, 27 (2): 93-98.   DOI: 10.12337/zgkqzzxzz.2022.04.008 Abstract （286）      PDF （1635KB）（526）       Knowledge map    Save Objective Immediate implant placement has been widely employed in the anterior teeth area. Unlike the immediate implantation in the anterior zone which serve the patients' aesthetic needs, treatment in the posterior region pays more attention to the recovery of masticatory function. However, most of the mandibular posterior teeth consist of two roots, implants that are placed immediately after extraction of posterior teeth are prone to mesial-distal deviation when drilling in the interradicular septa, which will ultimately affect the axial direction of the implants. This article introduces an exploration and practice of new treatment for immediate implantation in the posterior mandibular area, which can effectively solve the above problems. Methods Our team summed up a new method of “a comprehensive sequential treatment plan for immediate implantation of posterior mandibular teeth”, minimally invasive extraction of unreserved mandibular posterior teeth, and the maximum possible preservation of the volume of interradicular bone and the bone wall of the alveolar socket, accurate placement of implants in the alveolar socket interval. To this end, we have developed a special series of surgical instruments for immediate implantation in the posterior teeth area, applied for 18 patents, and completed the achievements of transformation and the production and clinical application of medical products. Results Clinical application confirmed that this method increased the initial stability and precision of implants of mandibular posterior teeth. Conclusion This scheme is conducive to the ideal position of implant placement effectively improving the success rate of immediate implantation of mandibular posterior teeth and is worthy of clinical promotion.

Clinical assessment of evaluating passive fit of implant-supported fixed prostheses Guo Yongqing, Ma Yun, Yu Hao Chinese Journal of Oral Implantology    2022, 27 (4): 243-247.   DOI: 10.12337/zgkqzzxzz.2022.08.008 Abstract （315）      PDF （1191KB）（502）       Knowledge map    Save Passive fit is closely associated with the long-term success rate of implant-supported prostheses. Therefore, clinical assessment of passive fit is important in the implant therapy. Based on the current evidence, an absolutely passive fit cannot be obtained, and a certain level of misfit was considered to be clinically acceptable. Various methods are applied to assess the passive fit of prostheses, which are mainly divided into two aspects: passiveness and marginal fit. The screw resistance test could be used to assess passiveness. Regarding marginal fit, the following methods are available: alternate finger pressure, visual inspection, tactile sensation, radiographs, one-screw test and disclosing materials. Each assessment method has its advantages and limitations. This article briefly reviewed the definition of passive fit and the common clinical assessment methods to provide references for clinical diagnosis and treatment.
