Oedema was measured preoperatively and on postoperative days 1, 3, and 7. Sixty-four patients completed the study. Bleeding was significantly higher and Fromme scale scores for surgical field visibility were significantly lower in the control group compared to the TXA groups (all P < 0.001). The TXA500 group demonstrated significantly reduced oedema compared to the control group (day 3: P = 0.037, day 7: P = 0.002), while the comparison of the TXA250 and control groups showed no significant difference. However, there was no significant difference in oedema between the two TXA groups. Hence, no firm conclusions can be drawn about the superiority of two-dose TXA over the single dose; this needs further investigation in a future study.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144048579","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}

However, the design process for PSIs is time-consuming and complicated, leading to high costs that hinder its widespread adoption. The aim of this study was to develop a novel workflow for designing PSIs using generative design (GD) techniques to streamline the process. The proposed workflow was implemented using GD-embedded software, Fusion (Autodesk Inc.), and tested by designing PSIs for one Le Fort I osteotomy case and one genioplasty case. The performance of the GD workflow was assessed through the time required for design and the basic properties of the GD PSIs. The hands-on time for the design was 94 min for the Le Fort I fixation plate and 45 min for the genioplasty plate. The maximum von Mises stress was 227.63 MPa for the Le Fort I fixation plate and 237.31 MPa for the genioplasty fixation plate. The GD-based workflow simplified and accelerated the design of PSIs for orthognathic surgery. Biomechanical analysis indicated the feasibility of generative designed patient-specific implants for clinical practice.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143813257","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}
