EXPLORING THE DIVERSE TYPES OF DENTAL CROWNS
Dental crowns have long been an essential part of modern dentistry, offering a versatile solution to restore and enhance the appearance and functionality of damaged or compromised teeth. Often referred to as “caps”, these restorations are designed to encase a tooth, provide protection, support, and aesthetic improvement. With advances in dental technology, there are several types of dental crowns available, each with its own unique properties and applications.
Let’s delve into the diverse world of dental crowns and understand their characteristics, benefits, and best uses.
HOW MANY DIFFERENT TYPES OF CROWNS ARE THERE?
- Porcelain-Fused-to-Metal (PFM) Crowns
Porcelain-fused-to-metal crowns combine the strength of metal with the aesthetics of porcelain. Layered with porcelain to achieve a natural tooth appearance, they comprise a metal substructure for durability. While they offer good aesthetics and strength, the presence of metal underneath the porcelain may cause a slight reduction in translucency and light transmission, especially with front teeth, or in areas with gum recession. - All-Ceramic or All-Porcelain Crowns
All-ceramic or all-porcelain crowns eliminate the presence of metal entirely. This results in crowns that are highly aesthetic, making them an excellent choice for front teeth and highly visible areas and suitable for individuals with metal sensitivities. Advances in material technology have made these crowns stronger and more durable, making them viable for both front and back teeth. Their lifelike appearance makes them a top choice for achieving a natural smile. They are not, however, the first choice for back teeth on patients with severe grinding/clenching habits, as they can crack under great forces like these. - Metal/Gold Crowns
Made from alloys like gold, platinum, or palladium, they are renowned for their durability and longevity. They can withstand heavy biting forces and are less likely to fracture. Although not as visually appealing as ceramic or porcelain crowns, these crowns are frequently employed for molars and less visible teeth due to their emphasis on strength. They are also an excellent choice for very short teeth, offering protection without impacting the tooth nerve during preparation. - Zirconia Crowns
Zirconia crowns have gained popularity due to their exceptional strength and aesthetics. Zirconia, a crystal-clear material akin to porcelain, can be meticulously shaded to blend seamlessly with adjacent teeth. These crowns excel in situations where both durability and a natural look are essential, particularly in areas subject to substantial chewing pressure. - CAD/CAM Crowns (Computer Aided Design/Computer Aided Manufacturing)
Milled in the office from a single block, these are typically referred to as a “same day” or “chairside” milled crown. This process involves using CAD/CAM technology to design and fabricate the crown directly in the dental office, often within a single appointment. The technology allows the dentist to take digital impressions of the patient’s teeth, design the crown using specialized software, and then mill it from a solid block of dental material right on-site. Although this is VERY convenient, for both the Dr. and patient, the technology has not yet caught up with our traditional methods of making crowns that look and fit perfectly, with the control of or ability to get the natural looking esthetics we are able to achieve with other types of crowns.
The fit, although utilizing recent technology, is still HIGHLY dependent on excellent operator skills, which is difficult to find. Many temporary crowns we encounter have poor fit, necessitating replacement within a brief period. Sadly, patients are not always aware of this, because it’s in the small details of the margins.
If you are lucky enough to find a dentist who is truly excellent at capturing an accurate digital impression, the esthetics of these one-block milled teeth still just don’t compare (yet) to that of crowns made by the hands and eyes of skilled dental lab technicians. These computer-generated crowns lack aesthetic detail as they are monochromatic and unable to layer different colors for custom-matched teeth, hindering their ability to achieve truly beautiful results. Maybe down the road, they will be able to. But for now, we do not recommend this option.
- E-Max Crowns
Made from a lithium disilicate ceramic. this high-strength material offers excellent aesthetics and durability. Known for their translucent qualities, which closely resemble natural teeth, they are suitable for anterior (front) and posterior(back) teeth, providing both visual appeal and strength. - Temporary Crowns
Temporary crowns serve as aesthetic and protective placeholders during the fabrication of a permanent crown. Made from acrylic or plastic, they are not intended for prolonged use. Their primary role is to safeguard the prepared tooth temporarily and uphold correct spacing and gum shape until the final restoration is complete.
IS THERE A COST DIFFERENCE?????
In some rare cases, it may vary slightly. For instance, a gold crown on a large molar would require much more gold to make than a typical crown. So in a case like this, it might be a more expensive option. But typically, our crown fees do not vary much at all.
HOW DO I KNOW WHICH TYPE OF CROWN IS BEST FOR MY SITUATION?
In choosing the appropriate type of dental crown, several factors come into play. These include the location of the tooth, the patient’s aesthetic preferences, the functional requirements, and any budgetary considerations. We work closely with our patients to determine the most suitable crown material for each individual case.
The wide array of crown options available today ensures that patients can receive tailored solutions that meet their unique needs. Whether it’s prioritizing aesthetics, durability, or a both, crowns play a vital role in restoring smiles and maintaining oral health.
