Comparison of the Accuracy of Implant Position Using Surgical Guides Fabricated by Additive and Subtractive Techniques

“…The apical deviation results are within the range of those in the current literature that show deviation means of 0.17±0.85 mm in in vitro studies (84) . Overall, apical deviation often has more deviation than the coronal portion in previous studies (57,83) , as was also observed in our study.…”

“…Findings of this study were consistent with the current literature and confirmed the results of the other studies. The results are within the range of the results reported by previous studies which show mean deviations of 1 mm of distance at the apical and coronal parts and 5 degrees angular deviation (42,61,65,83) . The planned and actual implant positions presented a small degree of deviation which can be expected from a fully-guided surgical approach for implant placement (61,65) .…”

Fully Digital Workflow for Planning Static Guided Implant Surgery: A Prospective Accuracy Study

“…[2,[16][17][18][19][20][21]. One in vivo study investigating the accuracy of the sGIS by a fully digital planning modality has been reported [22]. A comparable result to conventional guided implant surgery was observed.…”

“…To our best knowledge, however, only one prospective study has examined the in vivo accuracy of sGIS based on a fully digital planning procedure. Skjerven et al [22] examined the in vivo accuracy of 27 implants in 21 patients using a fully digital planning modality and SLA surgical guides. The mean lateral deviation at the implant platform/apex, depth deviation, and angular deviation were 1.05 mm / 1.63 mm, +0.48 mm, and 3.85º, respectively.…”

Intraoralscanner im Fokus – mehr als nur eine digitale Abformung?

“…Ist die Genauigkeit von Ganzkieferscans für die prothetische Versorgung einer "Ohr-zu-Ohr"-Versorgung als eher kritisch zu bewerten, so ist die Verwendung eines Situationsscans zur Verlaufskontrolle innerhalb der Kieferorthopädie [8] bzw. zur Überlagerung von DVT-Aufnahmen für die digitale Implantatplanung als sinnvolle und hilfreiche Indikation anzusehen [9].…”
