The Indirect Filling Options
Inlays and onlays are dental restorations used by a select number of dentists. In certain cases, inlays and onlays are a conservative alternative to full coverage dental crowns. Also known as indirect fillings, inlays and onlays offer a well-fitting, stronger, longer lasting reparative solution to tooth decay or similar damage. These restorations are beneficial from both an esthetic and functional point of view.
Inlays and onlays can often be used in place of traditional dental fillings to treat tooth decay or similar structural damage. Whereas dental fillings are molded into place within the mouth during a dental visit, inlays and onlays are fabricated indirectly in a dental lab before being fitted and bonded to the damaged tooth by your dentist.
The restoration is dubbed an “inlay” when the material is bonded within the center of a tooth. Conversely, the restoration is dubbed an “onlay” when the extent of the damage requires inclusion of one or more cusps (points) of the tooth or full coverage of the biting surface.
Inlays and Onlays:
The Benefits of the Conservative Approach
Superior Fit: Inlays and onlays offer a conservative preparation that preserves as much healthy tooth as possible. They are a great choice if you have minimal to moderate tooth decay that extends into a flossing area, offering an excellent alternative to full coverage crowns.
Tooth Color: Boasting esthetic longevity, inlays and onlays are not likely to discolor over time as tooth-colored resin fillings often do.
Tooth Structure Safeguard: Inlays and onlays preserve the maximum amount of healthy tooth structure while restoring decayed or damaged areas, helping to ensure functional longevity.
Easy Tooth Cleaning: Because the fit is tailored at all edges and the preparation minimal, your tooth can be easier to clean than it would be with full coverage restorative alternatives such as a dental crown.
Composite fillings can shrink during the curing process, whereas prefabricated porcelain or gold inlays and onlays will not (ensuring a precise fit).
Tight Space Fulfillments: If you have a cavity between your teeth, consider an inlay rather than a direct composite filling. Inlays are better at sealing teeth to keep out bacteria; they are easy to clean, will not stain and offer exceptional longevity.
Strength and Stability: Inlays and onlays are extremely stable restorative solutions for the treatment of decay. The superior fit and durable material make inlays and onlays a stable choice that can actually strengthen a damaged tooth.
Weak Tooth Protector: An onlay can protect the weak areas of the tooth. The procedure does not require the complete reshaping of the tooth.
Inlays and Onlays: The Procedure
Typically, an inlay or onlay procedure is completed in two dental visits.
During your first visit, your dentist must prepare the damaged tooth. A molded impression of the tooth is then taken and sent to a dental laboratory, where an inlay or onlay is fabricated. Inlays and onlays can be made from gold, porcelain or resin materials. The difference is in the appearance of the finished restoration. A fitted, provisional inlay or onlay (sometimes known as a temporary or “temp” for short) in the shape of the final restoration can be created during this visit to protect the tooth while the final restoration is being fabricated.
Your dentist might discuss with you the best type of inlay or onlay material to use. If esthetics is not a concern (for example, with back molars), gold is the best option. Porcelain inlays and onlays offer the best esthetics and are often used in the “smile line” areas. Resin materials may be the best option for people who grind their teeth and/or those with a misaligned bite (malocclusion).
During your second visit, the provisional temporary is removed and your inlay or onlay is placed.
Inlays and onlays are extremely stable restorations that seldom fail. Your dentist will check all margins to ensure a smooth fit with tight adjacent contacts. Your dentist will also check your bite to ensure that there are no occlusion-related problems affecting the margins of the restoration. Once fitted, the inlay or onlay is bonded onto the tooth and the margins are polished.
Avanta dental clinic is the only clinic in Armenia that offers то its patients the highest quality technology CEREC since 2008.
Cerec technology allows us to create a strong, customized, tooth-colored ceramic restorations right here at the office, usually within a single appointment. No temporary or second visit is required and the aesthetics are beautiful.
In the course of one visit, we can diagnose and prepare your damaged tooth, create an optical impression of the tooth, and use CEREC to design and mill a precision restoration, which is then permanently bonded to your tooth. No mess, no discomfort, no wait.
Get the smile you want and get back to your life. We know you’ve got more important things to do
CEREC inlays and onlays can be used to replace large existing fillings that need to be replaced but are to extensive for a new filling. We are very conservative and always keep tooth structure whenever possible. Instead of grinding down healthy tooth structure for a crown we only remove the old filling, any fractures and or decay. Then replace what’s missing with a custom puzzle piece of porcelain. The CEREC inlay or onlay will provide a strong, aesthetic, long-lasting restoration. Compared to composite (plastic) onlays Cerec’s enamel-like material looks and feels like your real teeth. It helps restore your tooth to its original strength. The cerec onlays or inlays have superior aesthetics to PFM (porcelain fused to metal) crowns. Because it’s metal free, it has more natural look and feel but most importantly we can see though it on X-rays and catch new cavities before it’s too late. As with any cerec restoration it can be done with one visit. You can avoid the impression materials, temporary and return appointment associated with lab- created onlays.
The Future of Inlays and Onlays
The materials used to fabricate inlays and onlays continue to evolve and become more natural and tooth-like in terms of structure, how they wear and their longevity.
The use of inlays and onlays for restorative purposes is not likely to be replaced by another treatment any time soon due to the combination of excellent functional longevity and esthetic naturalness associated with inlays and onlays.
In fact, maintaining tooth color over the course of your lifetime with an inlay or onlay may be further enhanced as the materials continue to improve, adding to the esthetic value of the restoration.
