Clinical application of implant technique in the pterygoid plate area-standard operational practice Pu Yiping, Gao Zhenhua, Zhao Zhengyi, Zou Duohong, Yang Chi, Zhang Zhiyuan Chinese Journal of Oral Implantology    2021, 26 (3): 143-151.   DOI: 10.12337/zgkqzzxzz.2021.06.001 Abstract （819）      PDF （1621KB）（765）       Knowledge map    Save The technique of TPP (T:maxillary tuberosity,P:pterygoid plate,P:palatine) implants has been proposed, that the pillar composed of maxillary tuberosity,the pyramidal process of the palatineand the pterygoid process of the sphenoid in pterygomaxillary region can provide a certain volume of compact bone. Inclined implants of 30-50 degrees are placed in pterygoid region. As it is located in the end of distal part of maxilla, the distal cantilever of the prosthesis is completely eliminated. TPP implants with good initial stability are often applied in combination with the implants in anterior and bicuspid areas to provide favorable conditions for immediate loading. This technique can be applied for immediate implant and immediate restoration of maxillary complete arch or unilateral multiple posterior teeth loss with alveolar bone atrophy. Furthermore,the success rate is high (>90%). Due to avoiding the procedure of bone augmentation approach in maxillary sinus region and simplifying the procedure of implant surgery, it could reduce the trauma of patients, relieve postoperative reaction and pain, shorten the course of treatment and provide a new clinical solution for patients with insufficient bone in maxillary posterior area, especially for the patients who can not undergo bone graft procedure. However, clinicians still face many difficulties achieving effectively clinical application of this technique, including standard surgical protocol, the correct position of the placement site, preoperative evaluation, the design of length and placement angle, the safety procedure of the surgery and implant direction control and risk management, etc. Our team established standard surgical protocol of TPP technique for immediate implant and immediate loading with severe bone deficiency in maxillary posterior area. We sincerely hope that the article will provide a reference and basis for clinicians when applying the technique to avoid complex operation and complications related to bone augmentation, popularize the clinical application of the technique.

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 （410）      PDF （1101KB）（642）       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.

Department of Oral Implantology, Hospital of Stomatology,Anhui Medical University, Hefei 230032, China Zhang Wanting, He Jiacai Chinese Journal of Oral Implantology    2022, 27 (1): 28-33.   DOI: 10.12337/zgkqzzxzz.2022.02.006 Abstract （426）      PDF （1405KB）（617）       Knowledge map    Save Objective To analyze impact factors of failed dental implant cases, and provide the theoretical guidance for clinical operation. Methods Cases in the Center of Oral Implantology from January 2012 to January 2021 with complete medical records were selected. The differences of gender, age, periodontal disease status, location of implants, implant, and surgical factors were compared between failed implants and successful implants. Statistical analysis software was SPSS 24.0. Statistical methods were the χ² test, Fisher’s Exact Test, and binary logistic regression. The level of statistical significance is expressed as P< 0.05. Results A total of 6124 implant cases were included in this study including 82 failed cases. The implant failure rate was 1.34%. There were 72 early failed cases and 10 late failed, with failure rates of 1.18% and 0.16%. Statistics results showed that the failure risk of men was higher than that of women (P< 0.001). Cases with implant diameter < 4.0 mm, implant length < 10 mm, and bone quality type Ⅳ showed a higher failure rate (P< 0.01). The failure risk in cases with internal sinus floor elevation (ISFE) was higher than those without the surgery (P< 0.001). The implant surface which were not sandblasted, large-grit, acid-etched (SLA) had a higher failure rate than those of SLA and SLActive (P=0.001). Age, upper or lower jaw, surgical site, the shape of implants, lateral approach of sinus floor elevation (LASF), and guided bone regeneration (GBR) had no statistical significance for dental implant failure. Conclusion The risk factors for the failure of dental implants were male, bone quality typeⅣ, implant diameter< 4 mm, implant length< 10 mm, non-SLA implant surface, ISFE surgical treatment, and periodontal disease.
