In clinical practice, it is not possible to determine whether it is better to make a crown or an inlay, it depends on the clinical indications. However, during the clinical preparation, the amount of inlay preparation is relatively less and the damage to the tooth body is less. However, for those teeth that are more damaged and require piles and crowns for reinforcement, crowns are generally recommended. If the amount of retained tooth is more, inlays are a better choice.
