When a tooth suffers from extensive decay, deep structural fractures, or the aftermath of root canal therapy, standard composite fillings no longer provide adequate protection. Under heavy chewing forces, a severely compromised tooth can easily split completely to the root. Consequently, full-coverage dental crowns represent the primary clinical mechanism to save your natural dentition.
A dental crown acts as a protective ceramic cap that completely encases the visible portion of the tooth down to the gumline. Therefore, it absorbs the direct impact of biting forces, distributing physical stress evenly across the jawbone. At AIC Dental Clinic, we utilize advanced bio-compatible ceramics to recreate your natural dental anatomy. Through meticulous physical shaping and precise digital design, we actively restore both maximum mechanical strength and lifelike optics to your smile.
Step 1: Micro-Shaping and Structural Preparation
A successful crown restoration depends heavily on creating adequate clearance within your bite. If a dentist places a ceramic shell over an unprepared tooth, the restoration will sit too high, disrupting your entire jaw alignment.

First, the clinician administers a local anesthetic to completely numb the target tooth and the surrounding gum tissue. Second, the dentist meticulously removes all active bacterial decay and older structural fillings. Finally, the doctor reshapes the remaining healthy enamel using specialized diamond burs. By gently reducing the top and sides of the tooth by approximately one to two millimeters, we create a perfectly tapered core that will support your permanent crown safely.
Step 2: Digital Video Impressions vs. Traditional Putty Trays
Once the tooth preparation meets strict clinical dimensions, we capture the exact shape of your mouth to guide the laboratory fabrication phase.
Therefore, our clinical team heavily utilizes advanced intraoral scanners. The digital software instantly builds a flawless three-dimensional model of your bite on screen, allowing us to evaluate the margins of the preparation with incredible clarity.
Step 3: CAD/CAM Laboratory Artistry and Materials Selection
While a temporary crown protects your prepared tooth from temperature sensitivity, our laboratory technicians actively engineer your permanent restoration.
Modern cosmetic dentistry relies heavily on monolithic zirconia and lithium disilicate (E-max) ceramics. Because these materials possess high structural density, they do not require a dark metal base to withstand heavy forces. The CAD/CAM software mill precisely carves the crown out of a solid block of pre-shaded ceramic. Next, an artisan ceramist applies custom glazes that mimic the exact translucency, microscopic ridges, and color gradients of your natural enamel.
Step 4: Definitive Clinical Bonding and Long-Term Care
During your final appointment, the dentist removes the provisional temporary cover and tests the fit of your permanent ceramic crown. We carefully verify the contact points between adjacent teeth to ensure food cannot trap easily in the gaps.
Once your bite balances flawlessly, the clinician conditions the underlying tooth structure with a mild etching agent. Finally, we apply a high-strength, dual-cure resin cement to bind the ceramic crown permanently to the tooth core. Maintaining your newly restored tooth requires zero lifestyle modifications. By simply flossing daily around the base of the crown and brushing twice a day with non-abrasive toothpaste, you protect the underlying margins from secondary decay and preserve your investment for decades.
