Inlay and onlay are dental restoration techniques commonly used to repair tooth damage, particularly that caused by extensive caries or trauma. These methods offer conservative and aesthetic solutions to restore optimal tooth function while preserving as much of the natural tooth structure as possible.
According to a study conducted by FKG UGM student Isyana Ginarsi Kalalembang under the supervision of Dr. drg. R. Tri Endra Untara, M.Kes., Sp.KG(K), titled Root Canal Treatment with Semi-Indirect Composite Resin Restoration Reinforced with Fiber Strips, such restorative techniques are essential for strengthening teeth that have undergone root canal treatment. They are especially applicable in cases where damage is severe enough to require strong and durable fillings. This underscores the role of inlay and onlay in maintaining the strength and stability of invasively restored teeth.
The Use of Inlay and Onlay in Dental Restoration
- 1. Definition and Function
- Inlay is a restoration placed within the tooth’s cingulum, filling cavities limited to the crown area without covering the outer surface, thereby preserving the natural tooth structure.
- Onlay covers a larger area, including the chewing surface, and may extend over multiple parts of the tooth crown. Essentially, onlay protects the entire upper portion of a tooth with severe damage
- Advantages and Benefits
- Provides better mechanical strength compared to regular composite fillings.
- Preserves as much of the natural tooth structure as possible.
- Aesthetic, as they are often made from porcelain or resin that resembles the natural color of teeth.
- Techniques and Materials
- Inlay and onlay can be made from porcelain, composite resin, or hybrid materials tailored to aesthetic and strength requirements.
- The procedure includes cleaning the cavity, creating a model in the laboratory, and reattaching the restoration with a strong adhesive material.
- Role in Root Canal Treatment
- After root canal treatment, teeth usually become weaker and more prone to fracture. Studies show that using inlay and onlay, further reinforced with fiber strips, helps increase the strength and durability of invasively restored teeth.

Inlay and onlay are effective and aesthetic restoration options, particularly for extensive damage where preserving the natural tooth structure is crucial. The application of modern materials and precise fabrication techniques can result in strong and long-lasting restorations—even in teeth that have undergone root canal treatment.
