بررسی ارتباط بین دانسیته استخوان ،resonance frequency و insertion torque
مقدمه: ایجاد استئواینتگریشن پس از کاشت ایمپلنت به 3 تا 6 ماه زمان نیاز دارد در حالی که بیماران تمایل به بارگذاری زود هنگام ایمپلنت دارند. استانداردی معین برای تعیین مقدار دانسیته استخوان، نیروی پیچشی نهایی (insertion torque (it و ثبات اولیه ایمپلنت وجود ندارد تا بتوان بر اساس ارتباط بین سه شاخص فوق زمان بارگذاری را مشخص نمود. هدف از این مطالعه تعیین ارتباط بین it و ثبات اولیه (rfa) و دانسیته اس...
متن کاملBiomechanical evaluation of dental implants with different surfaces: Removal torque and resonance frequency analysis in rabbits
STATEMENT OF PROBLEM Macroscopic and especially microscopic properties of implant surfaces play a major role in the osseous healing of dental implants. Dental implants with modified surfaces have shown stronger osseointegration than implants which are only turned (machined). Advanced surface modification techniques such as anodic oxidation and Ca-P application have been developed to achieve fas...
متن کاملBiomechanical evaluation of oversized drilling technique on primary implant stability measured by insertion torque and resonance frequency analysis
BACKGROUND This study evaluated the influence of implant site preparation depth on primary stability measured by insertion torque and resonance frequency analysis (RFA). MATERIAL AND METHODS Thirty-two implant sites were prepared in eight veal rib blocks. Sixteen sites were prepared using the conventional drilling sequence recommended by the manufacturer to a working depth of 10mm. The remain...
متن کاملThe Relationship Between Resonance Frequency Analysis (RFA) and Insertion Torque of Dental Implants: an in Vitro Study
Purpose: The aims of the present study are to correlate the ISQ values, registered by the Osstell ISQ system, with the insertion torque during the placement of the implant, and to assess the influence of the thread initiator on the ISQ values and on the insertion torque. Materials and methods: 140 rough surface implants screw-shaped implants, placed in 10 bovine ribs, were assigned to Group A (...
متن کاملCorrelation of Fractal Dimension Values with Implant Insertion Torque and Resonance Frequency Values at Implant Recipient Sites.
PURPOSE Fractal analysis is a mathematical method used to describe the internal architecture of complex structures such as trabecular bone. Fractal analysis of panoramic radiographs of implant recipient sites could help to predict the quality of the bone prior to implant placement. This study investigated the correlations between the fractal dimension values obtained from panoramic radiographs ...
