تعتبر مقاومة الزركونيا للشيخوخة أمرًا مهمًا لعمليات الترميم طويلة المدى

Low‑quality zirconia may suffer low‑temperature degradation after years inside the mouth, leading to reduced strength and micro‑cracks. Modern high‑translucency zirconia with stabilised formula greatly slows this aging effect. For posterior crowns and bridgework, choose materials with proven aging test data. Thin‑layer monolithic zirconia for anterior teeth needs careful occlusal adjustment to avoid chipping. Proper sintering in‑lab also decides the final mechanical performance of every zirconia restoration.
