Titanium and its alloys have long been the backbone of dental implantology due to their combination of mechanical strength, light weight, corrosion resistance, and biocompatibility. However, as an inert material, titanium has limitations in terms of osseointegration and additional biological activities such as antimicrobial effects or advanced cellular interactions. Therefore, extensive research has focused on surface modification or the application of additional biomaterial coatings so that titanium implants are not only mechanically stable but also more biologically \u201cactive.\u201d<\/p>\n\n\n\n

One notable modification is aluminum oxide (Al\u2082O\u2083) coating using sputtering techniques combined with acid etching, as studied by Adella Syvia Maharani under the supervision of drg. Murti Indrastuti, M.Kes., Sp.Pros(K) and Dr. drg. Suparyono Saleh, Sp.Pros(K) in the study titled \u201cPengaruh Lama Etsa Asam pada Implan Gigi Titanium dengan Pelapisan Alumunium Oksida (Al2o3) Metode Sputtering terhadap Persentase Hemolisis (Kajian In Vitro).\u201d This research examined hemolysis (blood cell response) to assess the safety of titanium surface modifications.<\/p>\n\n\n\n

Research Focus: Acid Etching Duration, Al\u2082O\u2083 Coating, and Hemolysis<\/strong><\/h2>\n\n\n\n

In the study, titanium implants were coated with Al\u2082O\u2083 using the sputtering method. The surfaces were then subjected to acid etching for varying durations to modify surface topography or roughness. The primary objective was to evaluate how long acid etching could be applied without significantly increasing hemolysis (red blood cell damage), as excessively rough or reactive surfaces may damage blood cells during initial contact or implantation.<\/p>\n\n\n\n

These findings underscore the importance of balancing enhanced osseointegration with hemocompatibility (blood compatibility) in biomaterial surface design.<\/p>\n\n\n\n
