When it comes to restoring damaged teeth, dental onlays offer a perfect blend of strength, durability, and aesthetics. At McLevin Dental Clinic, we take great care in fabricating custom onlays that fit precisely and look natural. But have you ever wondered what really goes on behind the scenes when your dental onlay is made? In this blog, well take you through the detailed process of crafting these essential dental restorations.
What Are Dental Onlays?
Dental onlays are custom restorations designed to repair large cavities or damage that doesnt require a full crown. Unlike fillings, onlays cover one or more cusps of a tooth, preserving more of your natural tooth structure while restoring function and appearance.
Step 1: Preparing the Tooth and Taking Impressions
The fabrication process starts in the dental chair. After numbing the area, the dentist removes decay or old restorations and shapes the tooth carefully to receive the onlay.
Next, precise impressions of your prepared tooth and surrounding teeth are taken. McLevin Dental Clinic uses digital intraoral scanners that create highly accurate 3D images of your teeth, eliminating the discomfort and mess of traditional molds.
Step 2: Sending Digital Impressions to the Dental Lab
These digital impressions are then securely transmitted to our trusted dental laboratory. Using advanced CAD/CAM (computer-aided design and manufacturing) technology, lab technicians begin designing your onlay with exact dimensions.
This digital workflow speeds up the process and ensures exceptional precision, which translates into better fit and comfort.
Step 3: Material Selection and Onlay Fabrication
Dental onlays can be made from different materials such as porcelain, composite resin, or gold. At McLevin Dental Clinic, we focus on durable and aesthetic options like porcelain that mimic the natural translucency and color of your teeth.
Using the CAD design, the dental lab mills the onlay from a solid block of material or layers and fires porcelain to create a lifelike restoration. Skilled technicians pay close attention to contour, texture, and color to ensure the onlay blends seamlessly with your smile.
Step 4: Quality Control and Polishing
Before the onlay returns to the clinic, it undergoes thorough quality checks. This includes verifying dimensions, surface finish, and shade match.
Polishing the onlay to a smooth, glossy finish is critical as it reduces plaque buildup and improves longevity.
Step 5: Onlay Fitting and Cementation
Once your custom onlay arrives, the dentist carefully tries it in your mouth to check fit, bite, and aesthetics. Minor adjustments are made if needed for perfect comfort.
Then, the onlay is bonded securely to your tooth using dental cement. This strong adhesion restores the tooths function and protects it from further damage.
Why Precision in Onlay Fabrication Matters
An accurately fabricated onlay ensures:
Optimal chewing function without discomfort
A natural look that blends with your teeth
Protection of healthy tooth structure
Long-lasting durability
Poorly made onlays can cause sensitivity, bite issues, or even failure of the restoration.
