Complications with Computer‐Aided Designed/Computer‐Assisted Manufactured Titanium and Soldered Gold Bars for Mandibular Implant‐Overdentures: Short‐Term Observations

Abstract

Implant overdentures supported by soldered gold bars or milled CAD/CAM Ti-bars are a successful treatment modality but require regular maintenance service. These short-term observations support the hypothesis that CAD/CAM Ti-bars reduce technical complications. Fracture location indicated that the titanium thickness around the screw-access hole should be increased.

CAD/CAM‐fabricated implant‐supported restorations: a systematic review

“…Although, the search strategy was broadened possible eligible publications (Larsson & Vult von Steyern 2010;Larsson & Vult Von Steyern 2013)which the authors were aware ofwere missed. While scrutinizing these two papers, the authors realized that the search terms that have been applied were Jemt et al (1999) Sample size per study arm Balshi et al (2012) Study design Becker et al (2000) No characteristics on restorations Borges et al (2012) No characteristics on restorations Ericsson et al (2000) No characteristics on restorations Di Giacomo et al (2012) Sample size/study design € Ortorp & Jemt (2000) Interim results of included study Ercoli et al (2012) Study design/sample size € Ortorp & Jemt (2002) Interim results of included study Furze et al (2012) Sample size Henriksson & Jemt (2003) Sample size per study arm Giordano et al (2012) Sample size Romeo et al (2003) Study design/no CAD/CAM prostheses Meloni et al (2012) Quality of reporting Engquist et al (2004) Follow-up, study design Tahmaseb et al (2012) No characteristics on restorations/follow-up € Ortorp & Jemt (2004) Interim results of included study Biscaro et al (2013) Sample size van Steenberghe et al (2005) Study design/no CAD/CAM restorations Lin et al (2013) No characteristics on restorations Gallucci et al (2007) Sample size/study design Cordaro et al (2013) No characteristics on restorations Malo et al (2007) Study design/sample size Kanao et al (2013) No characteristics on restorations/sample size Sanna et al (2007) No characteristics on prostheses Katsoulis et al (2013) No response/quality of reporting Vafiadis (2007) Case report/study design (2010) Sample size/study design Alfadda (2014) In vitro design…”

“…The studies were grouped into studies reporting results on CAD/CAM-fabricated implant-supported single crowns (SCs), CAD/CAM-fabricated implant-supported partial fixed dental prostheses (FDPs), and CAD/CAM-fabricated implant-supported fixed dental full-arch prostheses (full-arch FDPs). If there were any uncertainties regarding the reported study materials, authors or coauthors were contacted (Pozzi et al 2012(Pozzi et al , 2013aWeinstein et al 2012;Katsoulis et al 2013;Kolgeci et al 2014;Lopes et al 2014;Worni et al 2014). The two investigators selected potential studies and after consensus the studies were included for extensive analyses.…”

Prevention of distal extension cantilever fracture in mandibular overdentures

“…[30][31][32][33][34][35][36] This study aimed at gaining insight in the effect of bar design 37 on its fatigue strength. The hypothesis was that the following distal bar extension features (bar cross-sectional area, bar design, bar extension length, and a rib support) had a significant impact on their resistance to fracture.…”

Implant therapy in the geriatric patient

“…Distal extensions are advisable to enlarge the support area even further, but often the denture height is not sufficient to accommodate the superstructure. Frequent fractures of these extensions will be reduced if recent CAD/CAM technologies for milled titanium bars are used 45) .…”
