Class III amalgam restoration is not indicated in which of the following cases?
**Core Concept**
Class III amalgam restorations are indicated for non-load bearing, non-functional occlusal surfaces of posterior teeth where minimal tooth preparation is required. This type of restoration is generally used for small cavities in molars and premolars.

These restorations are contraindicated in cases where a significant amount of tooth structure needs to be removed, as this would compromise the structural integrity of the tooth. Additionally, Class III amalgam restorations are not suitable for teeth with significant occlusal wear or those that are heavily decayed, as they may not provide adequate support or stability.
