Technical Report: Precisely Fitting Bars on Implants in Five Steps—A CAD/CAM Concept for the Edentulous Mandible

Abstract: Various treatment concepts have been presented for the edentulous mandible. Manufacturing tension-free and precisely fitting bars on dental implants was previously a great challenge in prosthetic dentistry and required great effort. Modern computer aided design/computer aided manufacturing technology in combination with some clinical modifications of the established workflow enables the clinician to achieve precise results in a very efficient way. The innovative five-step concept is presented in a clinical cas… Show more

“…Bar attachment is one of the popular attachment types as it offers better transmission of forces between the implants due to it's primary splinting effect, load sharing, better retention and the least post insertion maintenance. (4,5) Cast Cobalt-Chromium (CoCr) bars have been used in implant supported overdentures, not only as a solution to increase the strength of an acrylic prosthesis but also to equally distribute load barring forces across the implants. However, the traditional bar fabricated via conventional casting procedures often produced a misfit between implants and implant bars.…”

“…Mittlerweile wird die ursprünglich für festsitzende prothetische Lösungen wie Kronen, Inlays und Onlays etablierte CAD/CAM-Technologie (CAD/CAM: Computer-Aided Design/Computer-Aided Manufacturing) auch für mehrgliedrige Brückengerüste, Totalprothesen und Stegkonstruktionen verwendet Oberflächengüte von CAD/CAM-gefrästen Implantatstegen aus Titan und Kobalt-Chrom [15,16]. Die so produzierten Produkte versprechen eine hohe Stabilität, spannungsfreien Sitz, Kompatibilität mit vielen Implantatsystemen, Flexibilität in Therapie-und Designauswahl sowie eine hohe Präzision im Vergleich zu herkömmlich produzierten Stegkonstruktionen [17,18]. Dank der präzisen Anpassung der ebenfalls CAD/ CAM-gefrästen herausnehmbaren Sekundärstruktur erreichen CAD/CAM-Steg-Konstruktionen eine ähnliche Steifigkeit wie festsitzende Versorgungen und gewährleisten darüber hinaus einen angemessenen Zugang zu hygienischen Zwecken (▶ Abb.…”
