Implant site preparation was performed using a robotic system, and the total force (Ft) and axial force along the drill (Fz) during the surgery were recorded by the haptic robotic arm. The actual initial breakthrough point (drill contacting sinus floor) and complete breakthrough point (drill penetrating the sinus floor) were defined visually (the actual IBP and the actual CBP). The theoretical initial breakthrough point (the theoretical IBP) and the theoretical complete breakthrough point (the theoretical CBP) defined by the robot‐guided system and the CBCT were determined by real‐time force feedback and imaging distance measurement, respectively. The distance from the bottom of the resin model to the actual IBP and the actual CBP was defined as Di and Dt, respectively.ResultsThe difference in Fz began to increase significantly at 70°, while the difference in Ft became significant at 60°. When the angle was greater than 70°, there was no significant difference in the discrepancy between the actual and theoretical perforation points. Compared to judging the breakthrough point by CBCT, real‐time force feedback TSFE under robotic surgery achieved more accurate initial breakthrough point detection.ConclusionsThe smaller the angle, the larger the breakthrough force for the drill. The real‐time force feedback of haptic robotic system during TSFE could provide reliable reference for dentists. More clinical studies are needed to further validate the application of robotic surgery assisted TSFE.","PeriodicalId":50679,"journal":{"name":"Clinical Implant Dentistry and Related Research","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142265894","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}

The surface hydroxyapatite (HA) apposition, the pH change, proliferation and attachment assays, and various gene expression levels are assessed. After a 7‐mm implant was inserted 3 mm into the rabbit calvaria, vertical bone augmentation is performed around the implant and inside the scaffold in four ways: scaffold only, scaffold+bone graft, bone graft only, and no graft. Sacrifice is performed at 6, 12, and 24 weeks, and the various parameters are compared radiographically and histologically.ResultsHA apposition, cell proliferation, cell attachment, and expression of osteogenic genes increase as the proportion of BGS‐7 increase. In the in vivo test, a higher bone–implant contact ratio, bone volume ratio, bone mineral density, and new bone area are observed when the scaffold and bone grafts were used together.ConclusionThe 3D‐printed scaffold, a mixture of BGS‐7 and PCL, exhibit higher biological compatibility as the proportion of BGS‐7 increase.

Interimplant distance deviations differed within and among materials (&lt;i&gt;p&lt;/i&gt; ≤ 0.017), except for those between abutments 1 and 2 among materials (&lt;i&gt;p&lt;/i&gt; = 0.387). Marginal gaps of subtractively manufactured materials differed among abutments, while those of abutments 3 and 4 differed among materials (&lt;i&gt;p&lt;/i&gt; ≤ 0.003). AM frameworks mostly had lower marginal gaps at abutments 3 and 4 (&lt;i&gt;p&lt;/i&gt; ≤ 0.048).&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Conclusions&lt;/h3&gt;\u0000 \u0000 ","PeriodicalId":50679,"journal":{"name":"Clinical Implant Dentistry and Related Research","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cid.13362","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141581877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
