Finally, the implant on the right side was loose and removed after six months, which was failed without osseointegration. Otherwise, a good osseointegration was formed on the left side, and the implant was loaded routinely. In the right mandibular posterior area, there were fibro-osseous lesions with unremarkable imaging findings, which were finally diagnosed by histopathology. Mandible fibro-osseous lesions mainly refer to a mixture of pathological changes of fibrosis and ossification in technology. The performance of such lesions is not obvious or present with similar symptoms and radiographic appearances, which lead to difficulties in diagnosis. In this article, the causes of failure in this case were analyzed. Furthermore, the features of ossifying fibroma and fibrous dysplasia in clinical manifestation, radiology, histopathology and so on were reviewed in this article, in order to provide a risk assessment and early warning of implants with fibro-osseous lesions for clinic.

A concept of biological - driven implant therapy ——The inevitable trend of this paradigm shift in prevention of periimplantitis Li Dehua Chinese Journal of Oral Implantology    2021, 26 (2): 79-84.   DOI: 10.12337/zgkqzzxzz.2021.04.001 Abstract （571）      PDF （1101KB）（1455）       Knowledge map    Save Implant therapy has been developed as a routine modality for restoration of tooth missing with high predictability of treatment outcomes in a short or long run, based on rapid advancement of technology and innovation of treatment concepts. Contemporarily, restoration-driven implant placement is the fundamental principle, which has played an essential role in the progress of implant dentistry. Nonetheless, implants are artificial entities completely different from the natural teeth, especially with respect to the biological characteristics of implant-tissue interactions. The paradigm of implant treatment, thereby, should take these specific biological patterns of implant interface into consideration, not only satisfying the requirements of spatial positions of implants. This is the reason behind the necessity to propose the concept of biological-driven implant therapy. Starting from the predominant hypothesis of biofilm-induced periimplantitis, this article will comprehensively review the diversity of factors revealed that might induce or increase the risk of periimplantitis, including bacterial or non-bacterial factors, and elucidate thereafter the logical trend for the paradigm shift from restorative-driven to biological-driven implant therapy. The fundamental definition of biological-driven concept will be clarified and periimplantitis-related factors be discussed, eliciting a novel strategy for clinical prevention of periimplantitis.

The peri-implant cyst is often confused with peri-implantitis and retrograde peri-implantitis due to its rarity and destruction of peri-implant supporting bone. Therefore, the paper systematically reviewed the current literature on the peri-implant cyst in order to summarize its clinical manifestations, differential diagnosis, and treatment protocols.

Causes and management of mechanical complications in dental implant CHEN Chuishi, LI Yang Chinese Journal of Oral Implantology    2019, 24 (2): 82-85.   DOI: 10.12337/zgkqzzxzz.2019.06.009 Abstract （425）      PDF （631KB）（1293）       Knowledge map    Save Objective： According to explore the causes and treatment of mechanical complications in dental im- plant surgery. Methods： 8 cases of dental implant complications occurred in longgang central hospital, in- cluding 5 cases where the central screw rod of the implant carrier was broken and 3 cases where the base screw was broken when the implant was implanted for immediate repair were collected. According to dif- ferent implant systems and different mechanical complications, corresponding treatment schemes were im- plemented. Result: 7 cases of central screw rod and base screw of the device were completely removed. The postoperative prognosis was good, the implant was not loose, and the subjective satisfaction of the pa- tients was good after the repair. 1 case replanted after the implant was removed, 6 months after the final restorationand were satisfied. Conclusion： Preoperative examination and analysis not only minimize the complications of implantation repair but also improve the success rate of implantation surgery.
