In Core Advantages, the TiO₂ layer's stability is enhanced by its self-healing ability: if minor scratches occur, the layer reacts with oral oxygen and moisture to re-form within hours, maintaining long-term biocompatibility. For patients with systemic conditions like diabetes-who often have more sensitive oral tissues-titanium's low irritation risk reduces post-prosthetic complications, such as delayed tissue healing.
In Fabrication Tech, post-milling/SLM processing is critical: frameworks undergo ultrasonic cleaning to remove residual titanium powder (which can cause tissue irritation) and heat treatment (500-600°C for 1-2 hours) to relieve internal stress from manufacturing. This stress relief prevents micro-cracking during masticatory use, extending the framework's lifespan by 30-40% compared to non-treated counterparts. For SLM-produced frameworks, a final sandblasting step with alumina particles (50-100 μm) creates a micro-rough surface, improving bonding strength with veneering materials by up to 25%.
In Maintenance Note, patients using implant-supported frameworks should avoid alcohol-based mouthwashes (e.g., those with ≥15% ethanol), as they can disrupt the TiO₂ layer and irritate peri-implant tissues. Instead, chlorhexidine mouthwash (0.12%) used 2-3 times weekly balances hygiene and oxide layer protection.
