This clinicopathological study was performed to investigate the association between invasion patterns and LCLM with pT1/T2 OSCC, treated surgically without preoperative chemotherapy or radiation; 145 patients were included, of whom 21 developed LCLM. Various histopathological factors were analysed, including depth of invasion (DOI), grade, pattern of invasion (POI), and the Yamamoto-Kohama classification. Multivariable analysis revealed that grade and POI were independent prognostic factors for LCLM; higher grade (hazard ratio 3.49, P = 0.043) and POI (hazard ratio 9.35, P = 0.007) were associated with an increased metastasis risk. Notably, 88.9% of cases with worst pattern of invasion-5 (WPOI-5) demonstrated LCLM. The study suggests that a combination of POI and grade should be considered for more accurate prediction and management of the LCLM risk, potentially guiding decisions on elective neck dissection to improve patient outcomes. However, WPOI-5 is difficult to identify from biopsy specimens, highlighting the need for a comprehensive approach combining multiple factors to accurately identify cases with a poor prognosis.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144328224","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}

Platelet-rich fibrin (PRF) is an autologous biomaterial that promotes healing through the gradual release of cytokines and growth factors. This prospective, randomized, controlled, and patient-blinded study investigated whether PRF applied to the extraction socket reduces postoperative symptoms and complications. Ninety patients scheduled for mandibular third molar removal were randomized to receive PRF or no adjunct treatment prior to wound closure. Seventy-five patients completed follow-up and were included in the analysis. Postoperative outcomes including AO, infection, pain, trismus, analgesic use, and sick leave were recorded over 10 days. The incidence of AO was lower in the PRF group (3.0%) compared to the control group (11.9%), although the difference was not statistically significant. PRF treatment significantly reduced postoperative pain during the first six days. These findings suggest that while PRF may not significantly reduce AO incidence, it can contribute to improved patient comfort and recovery by decreasing early postoperative pain.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144295545","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 aim of this study was to develop and validate a simplified scoring system for predicting excessive intraoperative blood loss (IBL) during orthognathic surgery. This retrospective cohort study included 361 patients who underwent orthognathic surgery. Factors related to excessive IBL were analysed. The candidate predictors for excessive IBL were determined by logistic regression analysis. The performance of the model was assessed through its discrimination ability and a calibration plot. Internal validation was done by bootstrap resampling technique. The regression coefficients were transformed into a scoring system. Excessive IBL occurred in 32.7% of patients (118/361). The predictive scoring system included three predictors: body mass index (score 0, 1.5, 2: overweight, normal weight, underweight), systolic blood pressure (score 0, 1: <130, ≥130 mmHg), and operative time (score 0, 2.5: ≤4, >4 h). The area under the receiver operating characteristic curve (AUROC) for discrimination ability was 0.828 (internal validation: C-statistic 0.812). Risk was then classified as low (0-2.5 points) or high (3-5.5 points). The prognostic ability of this simplified scoring system was found to be clinically acceptable for predicting excessive IBL during orthognathic surgery.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144228068","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}

Exclusions encompassed reviews, opinion articles, books, conference references, studies using AI as a supplementary method, AI for teaching implant dentistry, and AI for implant fabrication, prothesis, or design. A total of 120 relevant papers were included. Risk of bias was assessed using PROBAST. Findings demonstrated extensive utilization of AI in various aspects of dental implantology: guided surgery, diagnosis, classification of oral structures, bone classification, classification of dental restorations, implant classification, implant planning, and implant prognosis. Deep learning algorithms were employed in 89.2% of studies, predominantly utilizing image data (72.0% two-dimensional images and 28.0% three-dimensional images). Publications doubled in 2022 compared to the previous year and have remained consistent since. Despite growth, the field remains relatively underdeveloped.

While free-tissue transfer is a favoured reconstructive approach, it may be contraindicated in the medically comorbid and failure may be catastrophic, resulting in significant morbidity. In such cases, zygomatic implant-retained prosthetic obturators provide an effective alternative. However, traditional zygomatic implant placement often requires the elevation of large full-thickness mucoperiosteal flaps, risking osteoradionecrosis in irradiated bone following postoperative radiotherapy. This technical note describes a novel method for fully guided, flapless zygomatic implant placement that was applied in a 74-year-old with a Brown Class IId maxillary defect following hemi-maxillectomy of a pT4aN0M0 right maxillary squamous cell carcinoma. Using virtual surgical planning, two zygomatic implants were placed utilizing 3D-printed tissue-borne drill guides based on the patient's obturator. These guides were designed with low tolerance flutes to minimize angular deviation and utilized hard and soft tissue undercuts to ensure stability. By using a flapless technique, trauma to the irradiated tissues was minimized, whilst achieving accurate zygomatic implant placement. This case highlights the importance of a multidisciplinary approach between the surgical, prosthetic, and engineering teams. Further studies are needed to validate the accuracy and predictability of this innovative approach.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144145251","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}
