Commentary to "Survival rate of Astra Tech implants with maxiilary sinus lift"

study was 4 mm, whereas that of Yoon et al.’s study was 1.2 mm. A study by Geurs et al. found a significant difference in implant loss when residual bone height was less than 4 mm, as compared to 5 mm or greater. The authors should not have drawn a conclusion solely based on one other similar study. The referenced study by Jurisic et al. is not the same as the study done by Yoon et al., and thu...

Survival rate of Astra Tech implants with maxillary sinus lift

OBJECTIVES The aim of this study was to retrospectively evaluate the clinical survival rate of Astra Tech implants in the maxillary molar region performed with sinus lift and bone graft. MATERIALS AND METHODS Ninety-nine Astra Tech implants (Osseospeed) placed in the maxillary molar region using sinus lift from September 2009 to February 2012 were selected with a minimum follow-up period of 1...

Cumulative survival rate of Astra Tech implants: a retrospective analysis

PURPOSE The aim of this study was to analyze the short-term predictability and reliability of Astra Tech implants according to the demographical distribution of patients and condition of implant sites and location of implants. METHODS Among patients treated with Astra Tech implant (Astra Tech AB) in the Department of Periodontology at the Dental Hospital of Yonsei University of College of Den...

Influence of perforation of the sinus membrane on the survival rate of implants placed after direct sinus lift. Literature update.

The aim of this paper was to review the procedures adopted when a perforation of the sinus membrane takes place during a direct sinus lift for filling with bone graft; and the survival of implants in those cases in which perforation of the sinus membrane occurred. A bibliographical search in PUBMED was carried out of articles published from 1997 to 2008, with the key words "sinus perforation" a...
