Abstract
This research article delves into a comprehensive quantitative analysis of three groundbreaking biocompatible materials titanium alloys, zirconia ceramics, and biodegradable polymers each designed to optimize dental implant performance. The mechanical assessments revealed titanium alloys' outstanding tensile strength of 900 MPa, compressive strength of 1,200 MPa, and an elastic modulus of 110 GPa, surpassing traditional materials. Zirconia ceramics displayed a harmonious balance of strength (700 MPa) and esthetics, showcasing versatility for various dental applications. Despite the lower mechanical strength (200 MPa), biodegradable polymers exhibited commendable flexibility and suitability for specific load-bearing scenarios. The corrosion resistance evaluations demonstrated titanium alloys' exceptional stability with a corrosion rate of 0.05 mm/year, ensuring long-term performance in physiological environments. Zirconia ceramics exhibited negligible corrosion, emphasizing robust resistance to chemical degradation. Biodegradable polymers, assessed for controlled degradation, displayed corrosion rates tailored for optimal tissue response. In terms of biocompatibility, titanium alloys showcased a 95% in vitro cell viability, coupled with histological evidence of robust osseointegration and minimal inflammatory responses in vivo. Zirconia ceramics demonstrated high biocompatibility through in vitro cellular responses and favorable tissue integration in histological studies. Biodegradable polymers sustained biocompatibility with controlled degradation, promoting tissue regeneration while minimizing inflammatory reactions. The economic feasibility analysis, encompassing initial expenses, maintenance, and potential complications, revealed titanium alloys as cost-effective, while zirconia ceramics exhibited competitive economic viability. The cost-effectiveness of biodegradable polymers varied based on specific applications, underscoring their suitability for targeted clinical scenarios. This study provides valuable quantitative insights, aiding clinicians, researchers, and manufacturers in evidence-based decision-making for the advancement of dental implant materials, ultimately contributing to improved patient outcomes and enhanced clinical practices.
