Advanced Applications of Polyetheretherketone (PEEK) in Pediatric Dental Care: A Contemporary Review
Keywords:
Polyetheretherketone, PEEK, Pediatric Dentistry, BiomaterialsAbstract
Polyetheretherketone (PEEK) has emerged as one of the most promising high-performance polymers in modern dentistry owing to its exceptional mechanical properties, biocompatibility, chemical stability, and esthetic potential. While its application in prosthodontics, implantology, and restorative dentistry has been extensively explored, its utilization in pediatric dental care remains comparatively underrepresented despite substantial clinical potential. The increasing demand for child-friendly, metal-free, lightweight, and biologically compatible dental materials has stimulated interest in PEEK-based solutions for pediatric patients. This review critically examines the contemporary applications of PEEK in pediatric dentistry by synthesizing evidence from existing literature regarding its physicochemical characteristics, biological performance, restorative capabilities, and future prospects. The review analyzes the material's structural properties, surface modification strategies, biomechanical behavior, and clinical adaptability in pediatric oral environments. Furthermore, it evaluates current evidence concerning crowns, space maintainers, prosthetic devices, orthodontic components, and implant-related applications. Comparative assessment with conventional dental materials demonstrates that PEEK offers several advantages including reduced plaque accumulation, favorable stress distribution, excellent wear resistance, and improved patient comfort. Nevertheless, limitations associated with bonding performance, esthetic customization, and long-term clinical validation remain important considerations. The findings indicate that PEEK represents a transformative biomaterial capable of addressing several challenges in pediatric dental rehabilitation while supporting minimally invasive and patient-centered treatment approaches. Continued research and clinical evaluation are required to establish standardized protocols and expand its application across pediatric dental specialties.
