Porcelain crowns represent a highly popular cosmetic dental technique. Whether addressing misaligned teeth or discoloration, these issues can be resolved quickly through porcelain crown technology. The lifespan of porcelain crowns typically ranges from twenty to thirty years, and with proper maintenance, they can last even longer. So, what factors determine the longevity of porcelain crowns?
1. Condition of the natural teeth
The lifespan of porcelain crowns is closely related to the condition of the natural teeth. Generally, if the natural teeth are in good condition, there are few missing teeth, and more tooth structure remains, the crowns will last longer.
2. Material Selection
Numerous types of porcelain crowns exist today, each with distinct properties, leading to variations in longevity. Among these, metal-based porcelain crowns offer the best durability. Their superior strength and overall characteristics contribute to a longer lifespan.
3. Technician Skill
The clinical technician's skill level is a critical factor in assessing the lifespan of a porcelain crown. The tighter the fit between the crown and the natural tooth, and the smaller the gap between them, the better it protects the natural tooth. A long-lasting porcelain crown must have excellent fit, which requires the technician to undergo proper specialized training to prepare the tooth into a suitable shape that meets fabrication requirements.
