If you want a smile that’s your crowning glory, you may need a crown to cover a tooth and restore it to its normal shape and size. A crown can make your tooth stronger and improve its appearance.
It can cover and support a tooth with a large filling when there isn’t enough tooth left. It can be used to attach a bridge, protect a weak tooth from breaking or restore one that’s already broken. A crown is a good way to cover teeth that are discolored or badly shaped. It’s also used to cover a dental implant. If Dr. Trombka recommends a crown, it’s probably to correct one of these conditions. Alpine Dentals’ primary concern, like yours, is helping you keep your teeth healthy and your smile bright!
If you’re missing one or more teeth, you may notice a difference in chewing and speaking. There are options to help restore your smile.
Bridges help maintain the shape of your face, as well as alleviating the stress in your bite by replacing missing teeth.
Sometimes called a fixed partial denture, a bridge replaces missing teeth with artificial teeth, looks great, and literally bridges the gap where one or more teeth may have been. The restoration can be made from gold, alloys, porcelain or a combination of these materials and is bonded onto surrounding teeth for support.
Unlike a removable bridge, which you can take out and clean, a fixed bridge can only be removed by a dentist.
An implant bridge attaches artificial teeth directly to the jaw or under the gum tissue. Depending on which type of bridge your dentist recommends, its success depends on its foundation. So it’s very important to keep your remaining teeth healthy and strong.
Crowns or Bridges vs. Dental Implants?
Crowns and conventional bridges or dentures may not be your only options when replacing missing teeth. For some people, dental implants offer a smile that looks and feels very natural. Surgically placed below the gums over a series of appointments, implants fuse to the jawbone and serve as a base for individual replacement teeth, bridges or a denture.
Dental Crowns & Dental Bridges – Materials Comparison chart
|Comparison of Indirect Restorative Dental Materials|
|FACTORS||ALL-PORCELAIN (ceramic)||PORCELAIN Fused to metal||GOLD ALLOYS (high noble)||BASE METAL ALLOYS (non-noble)|
|Porcelain, ceramic or glass-like fillings and crowns.||Porcelain is fused to an underlying metal structure to provide strength to a filling, crown or bridge.||Alloy of gold, copper and other metals resulting in a strong, effective filling, crown or bridge.||Alloys of non-noble metals with silver appearance resulting in high strength crowns and bridges.|
|Inlays, onlays, crowns and aesthetic veneers.||Crowns and fixed bridges.||Inlays, onlays, crowns and fixed bridges.||Crowns, fixed bridges and partial dentures.|
Leakage and Recurrent Decay
|Sealing ability depends on materials, underlying tooth structure and procedure used for placement.||The commonly used methods used for placement provide a good seal against leakage. The incidence of recurrent decay is similar to other restorative procedures.|
|Brittle material, may fracture under heavy biting loads. Strength depends greatly on quality of bond to underlying tooth structure.||Very strong and durable.||High corrosion resistance prevents tarnishing; high strength and toughness resist fracture and wear.|
Cavity Preparation Considerations
|Because strength depends on adequate porcelain thickness, it requires more aggressive tooth reduction during preparation.||Including both porcelain and metal creates a stronger restoration than porcelain alone; moderately aggressive tooth reduction is required.||The relative high strength of metals in thin sections requires the least amount of healthy tooth structure removal.|
|These are multiple step procedures requiring highly accurate clinical and laboratory processing. Most restorations require multiple appointments and laboratory fabrication. Moderate resistance to fracture in high-load restorations. Low resistance to fracture. Low to moderate resistance to fracture.|
Resistance to Wear
|Highly resistant to wear, but porcelain can rapidly wear opposing teeth if its surface becomes rough.||Highly resistant to wear, but porcelain can rapidly wear opposing teeth if its surface becomes rough.||Resistant to wear and gentle to opposing teeth.||Resistant to wear and gentle to opposing teeth.|
Resistance to Fracture
|Prone to fracture when placed under tension or on impact.||Porcelain is prone to impact fracture; the metal has high strength.||Highly resistant to fracture.|
|Biocompatibility||Well tolerated.||Well tolerated, but some patients may show allergenic sensitivity to base metals.||Well tolerated.||Well tolerated, but some patients may show allergenic sensitivity to base metals.|
Sensitivity, if present, is usually not material specific.
|Low thermal conductivity reduces the likelihood of discomfort from hot and cold.||High thermal conductivity may result in early post-placement discomfort from hot and cold.|
|Esthetics||Color and translucency mimic natural tooth appearance.||Porcelain can mimic natural tooth appearance, but metal limits translucency.||Metal colors do not mimic natural teeth.|
|Relative Cost to Patient||Higher; requires at least two office visits and laboratory services.||Higher; requires at least two office visits and laboratory services.||Higher; requires at least two office visits and laboratory services.|
