BEHAVIOR OF IMPLANT STABILITY DURING IMPLANT TREATMENT: IN VIVO STUDY

Abstract

Implant stability is essential parameters that indicate the success of the implant treatment. However, the relation between implant stability, osseointegration and also remodeling process during that period is still unclear. This study was to evaluate the behavior of implant stability during implant treatment period.To investigate the behavior of the implant stability and its relation with quality and quantity of the bone during implant treatment, eight dental implant patients have been involved. Series of monitoring stages were conducted. The implant stability for each stage were measured using Resonance Frequency Analysis (RFA) devise and the behavior of quality and quantity of the bone during treatment have been monitored by using CBCT data. The phases of monitoring are divided into 3 phases; phase 1 is immediately after implant insertion, phase 2 is immediately after crown installation (4 month after implant insertion), and phase 3 is 1 month after crown installation (5 month after implant insertion).  The results were tabulated and analyzed using statistical software namely SPSS 20.5 to examine the correlation between basic measurement of bone quality and quantity and ISQ. The results show that during 4 month after implant insertion  period, the density of bone around the implant are decrease, this period was predicted as remodeling process. After 5 moth since implant insertion, the density start to increase. This phase possibly indicated the starting phase of osseointegration process. In addition, the ISQ for each patient was increased significantly. The primary implant stability was correlated with the space availability and bone quantity and quality, the result shows that the implant stability is proportional with the height of the mandibular and cortical thickness and inversely with width of mandibular. The highest correlation with the primary implant stability is the product of cortical thickness with the height of mandibular. There is a significant correlation between implant stability (ISQ) with dimension of site implant and density of bone.
