A dental restoration that covers only a portion of the tooth’s surface, leaving the lingual or palatal aspect exposed, typically fabricated from gold. This type of restoration prioritizes the preservation of tooth structure and reduces the potential for occlusal interference.
Its utilization offers significant advantages in specific clinical scenarios, particularly when minimal intervention is desired. Historically, these restorations have been favored for their biocompatibility, durability, and ability to conform precisely to the prepared tooth structure, ensuring optimal marginal adaptation and reduced risk of secondary caries. They are a time-tested approach to restoring function and esthetics.
