A literature search was performed in Scopus, MEDLINE/PubMed, and Cochrane Library to find randomized clinical trials that used ATBG to augment bone defects following impacted mandibular third molar surgery and compared this with normal healing or with other materials. Eight studies were included, six of which were included in the meta-analysis. The results showed that sites grafted with ATBG yielded significantly higher bone defect fill (standardized mean difference (SMD) 1.10, 95% confidence interval (CI) 0.20-1.99, P = 0.016) and significantly less probing depth (SMD -1.46, 95% CI -2.53 to -0.39, P = 0.007) when compared to the control, at 6 months postoperatively. Based on the GRADE system, the level of evidence on these outcomes was judged as moderate. Within the limitations, this study showed that the ATBG could be an alternative to other materials for augmenting bone defects following the surgical removal of an impacted mandibular third molar, offering the option of using the extracted tooth to produce a material that can be used for bone regeneration.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143451193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three-dimensional condylar movements from pre-surgery to immediately post-surgery and from pre-surgery to 1 year post-surgery were significantly greater in Class II patients than in Class III patients (both P < 0.001). Additionally, Class II patients exhibited more restoration movements to the preoperative position from immediately post-surgery to 1 year post-surgery, correlating with the volume reduction (r = -0.53, P = 0.007), which in turn correlated significantly with mandibular relapse (r = 0.63, P < 0.001).

This prospective randomized controlled trial employed a single-blind design. Overall, 112 patients were randomized to four groups based on the antiseptic assigned for the intervention: control, chlorhexidine (CHX), povidone-iodine (PI), and hydrogen peroxide (HP). The patients were followed up on days 1, 3, 7, and 15 after surgery, and pain and swelling were assessed. Data were analysed using ANOVA and post hoc multiple comparison tests. The CHX and HP groups demonstrated significantly lower mean pain scores compared to the control group on days 3 (P = 0.021, P = 0.033) and 7 (P = 0.002, P = 0.017). Regarding the difference in swelling from baseline (before surgery) on each follow-up day, the CHX and HP groups showed significantly less swelling compared to the control group on days 1 (P = 0.023, P = 0.012), 3 (P = 0.007, P = 0.001), and 7 (P = 0.002, P = 0.018). Moreover, the CHX and HP groups demonstrated significantly lower mean swelling changes from baseline compared to PI: CHX vs PI on day 7 (P = 0.032), HP vs PI on day 1 (P = 0.037). In conclusion, chlorhexidine and hydrogen peroxide solutions are highly beneficial options for socket irrigation following mandibular third molar surgery.

Additionally, the relationships between these nutritional indices and T-cell exhaustion in the peripheral blood of the patients were analysed. As a result, the Kaplan-Meier method revealed that lower OPNI was significantly associated with poorer overall survival (OS) and progression-free survival (PFS) (both P < 0.001). Likewise, the results of the multivariate analysis showed that a low OPNI was independently associated with poor 5-year OS (hazard ratio 4.36, P = 0.008) and PFS (hazard ratio 4.04, P = 0.010). Patients with a low OPNI had a significantly higher frequency of PD-1+ CD8+ T-cells than those with a high OPNI (P = 0.009). These findings demonstrate that pretreatment OPNI is a valuable independent prognostic indicator of OS and PFS in OSCC patients following treatment with ICI.

This study's goal was to present and clinically validate a virtual splint registration workflow. Ten dentate patients requiring revision surgery were included. Specific inclusion criterion for this study was the presence of at least two osteosynthesis screws on the orbital rim from a previous surgery. Dedicated orthognathic surgery software was used to fuse the maxillary dental scan with the computed tomography and generate a dental splint, which was imported into the navigation software and augmented with fiducial markers. Registration points were indicated virtually and the augmented splint was three-dimensionally printed. Intraoperatively, the splint was fitted on the maxillary dentition and the fiducial markers were used for registration. Accuracy of the registration procedure was quantified by calculating the difference between the landmarks acquired by indicating the pre-existing osteosynthesis material with the navigation pointer and in the virtual planning software. After acquisition of the landmarks, the screws were removed and surgery proceeded according to plan. A median target registration error of 1.53 mm was found. The advantages of the virtual splint registration workflow are that it does not require extensive computer-aided design skills or repeated preoperative imaging, and is non-invasive.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143371460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study patients (32 male and 18 female, mean age 25 years for both sexes) underwent Le Fort I osteotomy, with or without simultaneous genioplasty were performed by one experienced maxillofacial surgeon. Preoperative and postoperative multi-slice computed tomography scans were superimposed and contrasted with the surgical plan to evaluate any discrepancies between the planned and observed mandibular positions after surgery. The translational movements of the maxilla were a median 0.38 mm transversely, mean -5.29 mm anteroposteriorly, and median -1.00 mm vertically. Using a computed mandibular centroid, the absolute linear and angular discrepancies between the planned and observed mandibular autorotation movements were found to be within the clinically significant thresholds of 1 mm and 2°, respectively. It is concluded that CASS-planned mandibular autorotation is predictable when maxillary down-grafting and impaction does not exceed 5 mm and 4 mm, respectively.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143367077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
