Inlays and onlays are conservative restorations that preserve healthy tooth structure while reinforcing compromised cusps and proximal surfaces. They are excellent alternatives to full crowns in moderate structural loss.
Our lab supports precise marginal adaptation, occlusal contouring, and contact control to reduce chairside adjustment time. Available in high-strength ceramic (Emax, zirconia) and composite materials, each case is crafted to match natural tooth anatomy and occlusion.

| Criteria | Inlay / Onlay (Ceramic) | Direct Composite | Full Crown |
|---|---|---|---|
| Tooth reduction | Minimal–moderate (preserves cusps) | Minimal (additive) | Extensive (full coverage) |
| Longevity (10‑year survival) | 85–95% | 70–80% | 90–95% |
| Esthetics | Excellent (custom shading) | Good, but may discolor | Varies (ceramic best) |
| Strength | High (ceramic) | Moderate | Highest (full coverage) |
| Cost efficiency | Mid‑range | Lowest | Higher |
Preserves up to 60% more healthy tooth structure compared to full crowns. Ideal for vital teeth with moderate defects.
Modern ceramics provide wear resistance similar to natural enamel and withstand occlusal forces when properly bonded.
Multilayer ceramic blocks mimic natural translucency, fluorescence, and surface texture, blending seamlessly with adjacent teeth.
Conservative ceramic restorations explained
An inlay fits within the cusp tips of a tooth, like a large filling. An onlay extends over one or more cusps, providing additional structural reinforcement. Onlays are indicated when cusp coverage is needed.
With proper oral hygiene and regular checkups, they typically last 10–15 years or more. Bonded ceramic restorations have excellent longevity, often surpassing direct composites.
When tooth structure is still adequate, inlays/onlays are more conservative and often preferred. Crowns are necessary when remaining tooth structure is insufficient for adhesive bonding or when full cusp coverage is required.
Yes. Emax is the most popular for esthetics and strength. Zirconia is even stronger and recommended for patients with heavy bruxism. Composite options are available for transitional cases.
Deyu Dental Lab offers a 5‑year limited warranty against material fracture or manufacturing defects under normal function. Fit and shade issues are promptly addressed.
We accept both. Digital impressions (iTero, 3Shape, CEREC) provide the highest precision for inlay/onlay fabrication. Conventional PVS impressions are also welcome with a rigid tray.
