However, current single-mode systems, using either optical navigation or electromagnetic (EM) navigation, suffer from either occlusion or magnetic interference when simultaneously tracking the mandible and surgical saw in mandibular angle osteotomy (MAO). To resolve this, we propose a hybrid optical and EM navigation system (HOENS), utilizing optical navigation to track the surgical saw and EM navigation to track the mandible. A distance-based automatic hybrid navigation strategy is introduced to integrate both navigation approaches, leveraging the strengths of each. We conducted experiments with mandible phantoms to verify the effectiveness and accuracy of HONES. Results demonstrate that under laboratory conditions, with some nearby metallic interference, HOENS achieves an average hybrid navigation accuracy below 2 mm. Further evaluation of magnetic interference from the surgical saw on the EM sensor validated the necessity of our hybrid navigation strategy. Finally, we conducted osteotomy experiments on the mandible phantoms, where HOENS operated normally and provided precise visual guidance, with an average setup time of less than 20 min. Consequently, HOENS is feasible and effective for assisting surgeons in MAO, meeting clinical accuracy requirements, and shows promising potential for future clinical applications.</p>","PeriodicalId":54851,"journal":{"name":"Journal of Cranio-Maxillofacial Surgery","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143674861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eight different implant designs, consisting of two main groups with conical and cylindrical body geometry and four subgroups with four different thread designs, v-shaped, square, buttress, and reversible buttress in each group, were experimentally created in a computer environment. Implants 13 and 15 mm in length were inserted between the mental foraminas according to the All-on-Four concept, and the model was completed with an acrylic hybrid prosthesis created in a computer environment. A total force of 300N was applied with an oblique angle of 75° to the occlusal plane on the premolar and 1st molar teeth. Von Mises stresses (VMS) on the implants, and minimum principal stresses (Pmin) on the cortical and trabecular bones were evaluated using the 3D FEA. VMS and Pmin were lower in the cortical bone around conical, square-thread implants. Stress levels were highest on the cortical bone at the implant neck in all groups, with greater stress observed around posteriorly inclined implants.

The findings reveal a high level of patient satisfaction, and a survival rate of 92.5 % after an average follow-up of 804 days (SD ± 540 days).

Two other implants were removed due to persistent infection and suppuration, with a third implant scheduled for removal.
