Introduction This investigation delves into the mechanical behaviour of titanium dental implants, a preferred choice for tooth replacement due to their superior reliability over alternative materials. The phenomenon implant loosening, frequently induced by masticatory activities, underscores significance surface modification or texturing bolster interaction between and bone tissue. research comprehensively examines effects four distinct techniques five varied quality conditions on biomechanical performance these implants. Methods scope this study is delineated its focus implants diameters 4 mm 6 mm, with lengths measuring 9 12 respectively. Furthermore, analysis incorporates evaluation different coatings—hydroxyapatite, HA3TO, HA3Sr, HA1.5TO1.5Sr—to investigate efficacy in enhancing osseointegration process textured surfaces Results experimental design entails assessment stress distribution within coatings, alongside strain exerted surrounding cancellous bone, under an average vertical biting force. A comparative solid those subjected has been conducted. comparison elucidates advantageous microstrain profiles presented certain surfaces, which are deemed more conducive optimal osseointegration. Discussion Notably, across all examined textures, application hydroxyapatite (HA) modified HA composition (HA1.5TO1.5Sr) demonstrates significant improvements stability, particularly scenarios involving weak very conditions. study's findings contribute ongoing advancement technology, emphasizing critical role coating strategies promoting longevity integration environment human oral cavity.
