— Understanding the Procedure

What are inlays and onlays?

An inlay is a ceramic restoration that fits precisely within the cusps of a posterior tooth — replacing a large area of missing or decayed tooth structure at the centre of the biting surface. An onlay extends further, covering one or more of the outer cusps as well. Both are fabricated outside the mouth under controlled lab conditions and bonded in place with a precision adhesive protocol.

They occupy the space between a direct composite filling and a full crown. When a tooth has lost too much structure for a filling to hold reliably, but still has enough healthy enamel and dentine that a crown would be unnecessarily destructive, an inlay or onlay is the correct restorative choice. It preserves what is healthy, restores what is not, and does so with a material that is stronger and more durable than anything placed directly in the mouth.

At Tricity Smiles, Dr. Sandhu assesses every damaged posterior tooth against these three options before recommending treatment — choosing the restoration that is most appropriate for the tooth, not the one that is easiest to perform.

Step by Step

What to expect during your appointment

A 60-minute preparation appointment followed by a fit and bond appointment when your restoration returns from the lab.

01

Precision Preparation

Under local anaesthesia, the damaged tooth structure is removed with an electric handpiece and high-magnification loupes. The preparation is designed to be as conservative as possible — removing only what is unsound, preserving every micron of healthy tooth.

02

3D Scan & Shade

A 3D intraoral scan captures the prepared tooth, the adjacent teeth, and the bite with precision — replacing the discomfort of traditional impressions entirely. Clinical photographs are taken for shade matching before and after preparation.

03

Lab Fabrication

The digital scan is transmitted to a top-tier dental lab in India. An Emax (lithium disilicate) inlay or onlay is milled and characterised to match your tooth precisely. A temporary restoration protects the prepared tooth while the lab works.

04

Try-In & Bond

The restoration is tried in, contact points checked, bite verified, and margins inspected under magnification. Once approved, it is adhesively bonded using the correct protocol for Emax. Post-insertion photographs and a flossability check confirm everything is right.

— The Material

Why Emax for inlays and onlays?

Emax (lithium disilicate) is the material of choice for ceramic inlays and onlays because no other single material combines its strength, optical properties, and adhesive potential in one restoration. It is not simply a preference — it is the clinical standard for indirect ceramic posterior restorations.

Exceptional Strength

Emax has a flexural strength of approximately 400 MPa — well above the bite forces generated by posterior teeth. It does not chip, fracture, or wear against opposing teeth the way older ceramics do.

Adhesive Bond Strengthens the Tooth

Unlike fillings, which sit in a cavity, Emax inlays and onlays bond adhesively to the entire prepared surface. This monobloc effect actually reinforces the remaining tooth structure, significantly reducing the risk of cuspal fracture.

Natural Optical Properties

Emax transmits and reflects light in a way that closely mimics natural enamel. The restoration blends seamlessly with the surrounding tooth — no dark margins, no opacity, no visible boundary between restoration and tooth.

Longevity

A well-placed Emax inlay or onlay lasts 15–20 years or longer. The clinical evidence for Emax longevity in posterior restorations is among the strongest in ceramic dentistry.

— Why Tricity Smiles

Why inlays and onlays require a different level of skill

Preparation Demands Precision

An inlay or onlay preparation has stricter design requirements than a crown or filling. The margins, wall angles, and internal line angles must be exact for the laboratory-fabricated restoration to seat passively and seal completely. This requires magnification loupes, electric handpieces, and a level of preparation discipline that is uncommon in general practice.

3D Scanning for Superior Fit

The accuracy of a 3D intraoral scan is the reason inlays and onlays fit consistently at Tricity Smiles. The marginal fit of an inlay or onlay must be near-perfect for the adhesive bond to work correctly. Traditional impression errors compound at every stage — the digital workflow eliminates this entirely.

Correct Bonding Protocol is Essential

Emax inlays and onlays must be bonded — not simply cemented — for the restoration to perform correctly. The adhesive protocol involves etching, silanating, and bonding in a specific sequence. Skipping or abbreviating any step reduces the bond strength and longevity of the restoration significantly. Dr. Sandhu follows the full protocol, every time.

US-Trained Restorative Expertise

Dr. Sandhu trained at USC and UCSF where indirect ceramic restorations are a core component of restorative dentistry. The technical skill, clinical eye, and material knowledge required to place these restorations correctly are not common — which is why most clinics in Chandigarh do not offer them.

— Our Philosophy

Precision over volume — why fewer dentists offer inlays and onlays.

An inlay or onlay takes more time, more technical skill, and more investment in equipment than the two alternatives on either side of it. A large direct composite filling is faster to place and easier to justify to a patient who just wants the problem fixed. A crown is a higher-fee procedure that is more straightforward to prepare and plan. An inlay or onlay sits in neither of these convenient positions.

It requires a preparation that demands more precision than a crown. It requires a 3D scan or impression that must be more accurate than a simple crown case because the marginal fit requirements are tighter. It requires an adhesive bonding protocol that is more involved than cementing. And it requires a dentist who is willing to have a longer conversation with a patient about why the slightly more expensive, slightly more time-consuming, less familiar option is the right one for their tooth.

We do not choose the easiest option. We choose the option that serves the tooth best — today and fifteen years from now.

At Tricity Smiles, inlays and onlays are offered because we have the training, the equipment, and the technical workflow to place them correctly. They represent what we consider the highest standard of conservative restorative dentistry — giving a damaged tooth the strongest, most tooth-preserving, longest-lasting restoration that can be placed at that stage of damage.

When a patient is told they need a crown on a tooth that still has significant healthy structure, the right question to ask is whether an onlay might be sufficient. When a large filling is recommended on a tooth whose cusps are already unsupported, the right question is whether an inlay would hold that tooth together more reliably over the next decade.

These are the questions Dr. Sandhu asks before recommending any restorative treatment. The answer is not always an inlay or onlay — but it is always the most appropriate option for the tooth as it presents at that moment.

—   FAQ

Inlay & onlay FAQs

Common questions about ceramic inlays, onlays, and how they compare to fillings and crowns.

What is the difference between an inlay and an onlay?
An inlay sits within the cusps of a tooth — it replaces the central portion of the biting surface without covering the outer cusps. An onlay covers one or more of the outer cusps as well. A crown covers the entire tooth above the gumline. An onlay stops short of full coverage, preserving more natural tooth structure than a crown while providing more protection than an inlay where cusps are compromised.
Emax ceramic inlays and onlays at Tricity Smiles start from ₹15,000. The final cost depends on the size and complexity of the restoration. All costs are discussed and agreed before treatment begins — no hidden charges.
For large cavities or heavily damaged teeth, yes. A direct composite filling in a large cavity is prone to shrinkage, microleakage at the margins, and wear over time. An Emax inlay or onlay is fabricated under controlled lab conditions, bonds with precision, and produces a significantly more durable restoration. For smaller cavities, a direct filling remains the appropriate and more conservative choice.
An inlay or onlay is indicated when a tooth has insufficient structure for a filling but still has enough healthy structure that a full crown would be unnecessarily destructive. A crown removes tooth structure from all sides to create a uniform preparation. An inlay or onlay removes only the damaged portion, leaving healthy enamel and dentine intact wherever possible.
Emax (lithium disilicate) combines high flexural strength, excellent optical properties, and a proven adhesive bond in a single material. It is the clinical standard for ceramic posterior restorations. Its bond to the tooth structure actually reinforces the remaining tooth, reducing the risk of cuspal fracture — which is particularly important for heavily restored posterior teeth.
A well-placed Emax inlay or onlay can last 15–20 years or longer with good oral hygiene and regular check-ups. Longevity depends on the size of the restoration, bite forces involved, oral hygiene, and whether a night guard is worn if the patient grinds or clenches.

After your inlay or onlay

What to expect and how to care for your restoration.

Immediately After Bonding

  • Avoid hard or sticky foods for 24 hours
  • Some sensitivity to temperature is normal for a few days — especially along the margins
  • If your bite feels uneven, call us — a minor occlusal adjustment is a quick fix
Long-Term Care
  • Brush margins carefully twice daily — where the ceramic meets the tooth
  • Floss daily — the contact point should pass floss cleanly
  • Attend your regular cleaning and check-up appointments
  • Avoid biting very hard objects — ice, hard candy, nutshells
  • If you grind at night, a custom night guard protects your restoration significantly
