Comparison of Primary Stability of Sinus Implants and Standart Implants

Abstract

Abstract Background The BoneTrust® Sinus implant (BTSI) enables optimal primary stability by its special design with reduced thread section in cases of reduced vertical bone availability, thus allowing in many cases a one-step operative procedure even if less than 5mm of the bone level is available in the sinus region. The aim of this in vitro study was to analyze the primary stability of BoneTrust® Sinus implant in comparison with standart implants. In the years 2015-2017, partially edentulous patients were consecutively provided with implant-supported fixed restorations with the use of 11 BoneTrust® Sinus implants of the Medical Instinct® System (Medical Instinct Production GmbH, Bovenden, Germany) (Group A) and the 11 standard OXY implants of Biomec System (Biomec system Italy) (Group B) at Baskent University, Department of Oral and Maxillofacial Surgery.In this study, measurements were conducted with the Resonance Frequency Analysis method by using Osstell device on 11 BoneTrust® Sinus implants of the Medical Instinct® System (Medical Instinct Production GmbH, Bovenden, Germany) and 11 standart OXY implants of Biomec System (Biomec system Italy). Results Primary and secondary ISQ values implants were compared and there was no statistically significant difference between these two groups in terms of these parameters.No significant difference was found between the two groups in terms of bone loss after 6 months. Conclusion This present study did not demonstrate a statistically significant difference, between the primary and 6th-month ISQ values of the standard implants group and sinus implants group.
