Implant/Tooth-Connected Restorations Utilizing Screw-Fixed Attachments: A Survey of 3,096 Sites in Function for 3 to 14 Years
Fugazzotto, Paul A. / Kirsch, Axel / Ackermann, Karl-Ludwig / Neuendorff, Gerhard
Numerous problems have been reported following various therapies used to attach natural teeth to implants beneath a fixed prosthesis. This study documents the results of 843 consecutive patients treated with 1,206 natural tooth/implant-supported prostheses utilizing 3,096 screw-fixed attachments. After 3 to 14 years in function, only 9 intrusion problems were noted. All problems were associated with fractured or lost screws. This report demonstrates the efficacy of such a treatment approach when a natural tooth/implant-supported fixed prosthesis is contemplated.
