Clinical analysis of extraction site preservation using Bio-Oss Collagen after extraction of maxillary molars Yu Jiuyue, Jia Wenhao, Fang Li, Wang Jian, Li Jiangming, Liu Han, Guo Qili Chinese Journal of Oral Implantology    2023, 28 (2): 90-96.   DOI: 10.12337/zgkqzzxzz.2023.04.004 Abstract （377）      PDF （1591KB）（465）       Knowledge map    Save Objective To investigate a clinical treatment method for extraction site preservation using Bio-Oss Collagen after extraction of maxillary molars. Methods The clinical data of 6 cases were retrospectively analyzed, and all 6 patients were treated with Bio-Oss Collagen for extraction site preservation after extraction of maxillary molar teeth. These six cases met the following characteristics: the affected tooth was destructed in the alveolar bone in the area of its furcation due to periodontitis or combined periodontal-endodontic lesions, and needed to be extracted; the remaining bone height in the top central part of the alveolar ridge was less than 3.5 mm after the extraction of the affected tooth; the bone walls of the buccal, lingual, mesial and distal parts of the extraction socket were nearly intact. After extraction of the affected tooth, the granulation tissue in the alveolar socket was thoroughly removed. Bio-Oss Collagen was placed in the alveolar sockets and the soft tissues were cross-sutured to hold the graft in place. The sutures are removed 7-10 days after surgery. CBCT was taken preoperatively, immediately postoperatively and at six months postoperatively. The vertical height of the remaining alveolar ridge was measured using Mimics 20.0 at five sites: buccal and lingual in the coronal position, mesial and distal in the median sagittal position, and central. Results Primary healing was obtained in all six patients. At 6 months after extraction, the patients had well healed alveolar sockets, normal gingival color and texture, and no change in attached gingival width. CBCT taken at 6 months after extraction showed no change or a small increase in alveolar crest height at the buccal, lingual, mesial and distal sites, but an increase of 3.48 to 7.89 mm at the central site, among the 5 sites measured. Conclusion After extraction of maxillary molars, Bio-Oss Collagen can be used for extraction site preservation if the surrounding bone wall height is adequate. This method causes less trauma, has a shorter operation time, and its results are similar to those of conventional extraction site preservation. Reference | Related Articles | Metrics

Clinical application of “tenon-mortise” based whole-process digital combined guide plate in complete-mouth implant surgery. Li Yan, Yang Qingran, Xu Guangzhou Chinese Journal of Oral Implantology    2021, 26 (5): 306-312.   DOI: 10.12337/zgkqzzxzz.2021.10.007 Abstract （369）      PDF （1567KB）（419）       Knowledge map    Save Objective This study was to conduct a preliminary investigation of the efficacy of “tenon-mortise” based combined digital whole-process surgical templates to assist in diagnosis, plan, and facilitate proper positioning for edentulous patients. Methods This clinical case analysis was to report the treatment of one case with advanced periodontitis, which in turn leads to loosening of teeth. Because of the advanced periodontitis, the remaining teeth were severely loose. A self-designed “tenon-mortise” based combined digital whole-process surgical templates were applied to guide the placement of the implant. The combined surgical templates include positioning plate, osteotomy plate, and implant plate. The connection between the two plates is based on the tenon-mortise joint, which facilitates implant surgery for edentulous patients. In addition, for the irregular alveolar ridge, the osteotomy plate, as one of the combined guided surgical templates, could be used to guide cutting and trimming the alveolar ridge. Using the self-designed “tenon-mortise” based combined digital guided surgical templates could successfully guide the entire surgical process. Results When comparing the planned and placed implant by CBCT, it was found that high accuracy was achieved by using the self-designed “tenon-mortise” based combined digital whole-process surgical templates. The mean angular deviation was 2.27°. The mean value of deviation at the shoulder and apex was 1.77 mm and 1.93 mm, respectively. The outcome of the immediate restoration was satisfying. Conclusion This self-designed template system provides a novel technique to guide whole-process digital implant surgery for edentulous patients. But the efficacy needs further investigation in clinical trials with larger sample sizes and longer follow-up periods. Reference | Related Articles | Metrics

Inflammatory modulation and applications of biomaterials in oral bone regeneration Zhang Yufeng, Wang Yulan Chinese Journal of Oral Implantology    2023, 28 (5): 304-309.   DOI: 10.12337/zgkqzzxzz.2023.10.002 Abstract （350）      PDF （1284KB）（300）       Knowledge map    Save Significant progress has been made in the field of oral bone regeneration, with growing recognition of the pivotal role played by inflammation regulation. Temporal and contextual regulation of inflammation is essential for achieving successful bone repair. In the context of oral bone regeneration, biomaterials are employed as scaffolds/bone grafts to promote bone tissue formation in defect areas. The intrinsic properties of biomaterials may impact the inflammatory process and its regulation. Additionally, biomaterials can serve as carriers for immuno-modulatory drugs, further influencing bone regeneration. A comprehensive understanding of how biomaterials modulate inflammatory responses holds the potential to accelerate the development of novel bone regeneration materials. This review provides an overview of the current status of research on biomaterials in the context of oral bone regeneration and inflammation response, summarizing the laboratory advancements. The aim is to provide clinicians and researchers with a theoretical foundation for the selection and development of regenerative materials. Reference | Related Articles | Metrics

This article describes the evolution of this technique and the technical points of the clinical approach. It is very difficult to assess the intactness of the maxillary sinus mucoperiosteum in transalveolar technique when simultaneous bone augmentation is required. The use of electronic endoscope is a very helpful method to better confirm the preparation depth of the implant site and the status of the maxillary sinus mucoperiosteum, thus effectively avoiding complications of bone augmentation due to the maxillary sinus mucoperiosteum perforation. This article focuses on the clinical procedures and considerations in the use of transalveolar technique for sinus floor elevation to provide a reference for clinicians to improve the predictability of this technique.

Implant placement with transcrestal sinus floor elevation using absorbable collagen sponge: an analysis of 6-month images using CBCT and mimics software Deng Lei, Cheng Yi, Zhao Nan, Chen Gang, Huang Haitao Chinese Journal of Oral Implantology    2022, 27 (3): 147-155.   DOI: 10.12337/zgkqzzxzz.2022.06.004 Abstract （330）      PDF （1380KB）（381）       Knowledge map    Save Objective To measure the changes in bone height and bone volume in the transcrestal sinus floor elevation using absorbable collagen sponge by cone beam computed tomography (CBCT) and three-dimensional measurement by mimics, and to analyze the factors affecting bone formation in the sinus. Methods A total of 14 patients (24 implant sites) were selected from December 2019 to December 2021 in the Department of Stomatology, The First Affiliated Hospital of Dalian Medical University. All patients underwent transcrestal sinus floor elevation using only the absorbable collagen sponge by grinding method, and the lifting space of the sinus floor was maintained by collagen sponge and implant. The perforation of the sinus floor mucosa was recorded during the operation. The height of new bone was measured by CBCT before and 6 months after the operation. Immediately and 6 months after surgery, the protruding length (PL) and lifting length (LH) of the maxillary sinus floor were examined by CBCT. New bone height (NBH) was measured 6 months after the operation. The CBCT image data were imported into Mimics Research software. Mimics software was used for modeling and registration, and Boolean arithmetic was used to calculate the new bone volume in the maxillary sinus. The factors affecting osteogenesis were analyzed by one-way ANOVA and stepwise multiple linear regression, and the regression simulation prediction equation was established. Results A total of 24 implants were implanted and the short-term retention rate was 100%. The mucoperiosteum of the maxillary sinus floor was perforated at three sites during the preparation of the implant socket, and the perforation rate was 12.5%. There was no perforation in the process of collagen sponge filling and implant implantation. And all implants achieved good osseointegration on imaging 6 months after surgery and successfully loaded. The average new bone height in the sinus was（3.09±0.99）mm and the volume of new bone in the sinus is （320.24±85.79）mm³ 6 months after the operation. According to Pearson correlation analysis, there was a linear correlation between LH, PL, and NBH and new bone volume ( P<0.05), one-way ANOVA showed statistically significant difference between sinus floor morphology groups ( P<0.01), and new bone volume in the round group was higher than that in the oval and pointy round groups ( P<0.05). Sinus floor morphology, gender, and PL were included in the multiple linear regression model, with a determination coefficient of 0.753. Conclusion Collagen Sponge, as the filling material for transcrestal sinus floor elevation without grafting technique, has good operation performance and can maintain the osteogenic space in the sinus cavity together with the implant to form new bone of a certain volume. In addition, the new bone formation may be related to LH, gender, PL, and sinus floor morphology. Reference | Related Articles | Metrics
