Herein, we have established a laser-based resonance frequency analysis (RFA) system with high-speed, non-contact, quantitative measurements of PSF to evaluate implant fixation strength for future investigation of surgical failure risk of implants. We investigated the characteristics of the laser RFA by comparison with conventional methods.\nPedicle screw was inserted in the vertebral pedicle of dissected human cadaver or artificial bone, followed by screw pull-out, peak torque, the implant stability quotient (ISQ) value obtained by magnetic dental RFA system and fixation strength of laser RFA. We compared outcomes using best-fit linear or logarithmic approximations.\nFor the model bone study, the resonance frequency (RF) versus the conventional methods showed strong correlations (logarithmic: peak torque: R = 0.931, vs pull-out force (POF): R = 931, p < 0.001) and (liner: peak torque: R = 0.842, vs POF: R = 0.840, p < 0.001). RF strongly correlated with the ISQ value using linear approximation (R = 0.981, p < 0.001). For the cadaveric vertebrae study, the correlation coefficients between RF and the conventional methods were significant regardless of approximation method (peak torque: logarithmic: R = 0.716 vs linear: R = 811, p < 0.001) (POF: logarithmic: R = 0.644, vs linear: R = 548, p < 0.05).\nThus, our findings revealed a constant correlation between RFA and the conventional methods, as a measurement validation, predicting its favorable support of intraoperative PSF.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1002/jor.24983","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://onlinelibrary.wiley.com/doi/10.1002/jor.24983","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1554-527X","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nakashima, Daisuke"}],"nameIdentifiers":[{"nameIdentifier":"1012459","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mikami, Katsuhiro"}],"nameIdentifiers":[{"nameIdentifier":"1012460","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kikuchi, Shunsuke"}],"nameIdentifiers":[{"nameIdentifier":"1012461","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishikino, Masaharu"}],"nameIdentifiers":[{"nameIdentifier":"1012462","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitamura, Toshiyuki"}],"nameIdentifiers":[{"nameIdentifier":"1012463","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hasegawa, Noboru"}],"nameIdentifiers":[{"nameIdentifier":"1012464","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsumoto , Morio"}],"nameIdentifiers":[{"nameIdentifier":"1012465","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakamura , Masaya"}],"nameIdentifiers":[{"nameIdentifier":"1012466","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nagura, Takeo"}],"nameIdentifiers":[{"nameIdentifier":"1012467","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masaharu, Nishikino","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1012468","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Toshiyuki, Kitamura","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1012469","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Noboru, Hasegawa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1012470","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Laser resonance frequency analysis of pedicle screw stability: a cadaveric model bone study","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Laser resonance frequency analysis of pedicle screw stability: a cadaveric model bone study"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-06-22"},"publish_date":"2020-06-22","publish_status":"0","recid":"81761","relation_version_is_last":true,"title":["Laser resonance frequency analysis of pedicle screw stability: a cadaveric model bone study"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:55:56.927354+00:00"}
