Zirconia crowns are known to be highly aesthetic, durable, biocompatible and more resistant to staining than natural teeth.
Your dentist can create them on-site using computer-aided design/computer-aided manufacturing (CAD/CAM), making the procedure possible in one visit and faster than with traditional ceramic materials.
Strength
Zirconia crowns are stronger than traditional metal substructure crowns, enabling dentists to make them thinner while still conserving more of the patient’s natural tooth structure during placement. As a result, zirconia crowns offer improved function as well as aesthetic restoration for improved restoration results.
Zirconia crowns offer more durability than their porcelain counterparts, which can chip easily under biting forces. Thanks to its greater strength, zirconia is less likely to fail under such strain.
Zirconia is also a biocompatible material, meaning it will not provoke allergic reactions like those caused by metal alloys used to craft PFM crowns – an essential consideration for patients who experience sensitivities to them.
Zirconia crowns offer many physical advantages for dental use. Their adaptable nature makes it easier for dentists to match them to the color and appearance of natural teeth; various levels of translucency allow you to achieve desired visuals, and they’re highly resistant to staining or discoloration.
Although zirconia is an excellent choice for most patients, it’s wise to consult your dentist prior to selecting a restoration material. Your dentist can assist in understanding where the tooth impairment lies within your bite and overall smile goals, and also explain the differences in strength, durability, cost repairability aesthetics between materials such as zirconia and others such as composite resin.
As with all dental crowns, zirconia crowns are not indestructible; more specifically, its occlusal surfaces are more likely to crack or fracture than its internal structure; therefore it’s vital that your dentist properly prepares your tooth before beginning restoration procedures. Proper preparation requires sufficient gingival reduction and an axial tooth thickness of 0.6 mm. In order to decrease microfractures risk and enhance aesthetics, an occlusal surface polish such as Alumina should also be applied as part of the preparation process. Use of ceramic overpress techniques has been found to significantly increase the strength of zirconia crowns by up to threefold, and has proven more resistant to fracture than lithium disilicate crowns [84, 85].
Aesthetics
Zirconia crowns provide a natural appearance, making them highly effective in cosmetic and restorative cases. Their translucent properties enable you to color-match them seamlessly to their surroundings for an attractive smile makeover. Furthermore, these materials are biocompatible – meaning that they won’t irritate sensitive gum tissue or trigger any allergies – making them long-term solutions.
Zirconia restorations differ significantly from PFM restorations in that they’re milled directly from a solid block of ceramic rather than bilayered. This ensures a sturdy crown without needing an additional metal substructure for stability; furthermore, zirconia boasts superior fracture resistance as well as being more suitable than any other material for combatting bruxism and parafunctional habits.
Zirconia can be utilized in numerous dental applications, from full-coverage crowns and bridges up to 16 units to inlays/onlays, screw-retained crowns and full-arch implant prostheses. This variety enables clinicians to select the optimal solution for each unique patient.
Monolithic zirconia is generally an opaque material, but manufacturers can create aesthetic zirconia crowns that more closely resemble the translucency of natural teeth. The material can then be stained and sintered at high temperatures to achieve this look without compromising strength of its crowns.
Zirconia crowns are most often prescribed to patients suffering from severe tooth wear in their front teeth, usually the front molars. Zirconia crowns can restore aesthetics as well as their ability to chew and speak normally while simultaneously decreasing pain and discomfort levels for improved self-confidence after treatment.
Repairability
With proper care and repair or replacement from the right laboratory, zirconia crowns can last many years with proper use. Unfortunately, like any dental material, zirconia isn’t perfect and may inevitably break or wear down over time requiring repair or replacement by patients themselves. When this happens, patients should contact a laboratory immediately as it will help make this process much smoother and simpler for themselves.
As with all restorations, proper homecare and regular maintenance visits are key to prolonging the longevity of a zirconia crown. Furthermore, this material is completely metal-free, which reduces gingival darkening as well as any risk of exposed metallic margins in case of recession.
Zirconia is an extremely strong material that is extremely difficult to break; however, zirconia crowns may become damaged if not manufactured or reduced accurately. A high quality zirconia dental lab will use an intraoral scanner to measure each patient’s teeth accurately and fabricate crowns that fit precisely, eliminating excess force that could potentially weaken or crack them.
Strength of zirconia crowns depends on their chemical makeup. The original BruxZir 3Y zirconia boasts unparalleled strength thanks to transformation toughening technology which stops crack propagation – this makes it virtually indestructible. However, some new “esthetic” zirconia products may use alternative formulations which don’t offer equal strength levels and have yet to undergo rigorous long-term testing.
One key to the durability of zirconia crowns lies in their cementation process. A skilled zirconia technician should use glass ionomer resin cement, an extremely strong bonding agent resistant to chipping and cracking. When dentists apply the crowns in situ, curing lights will harden the adhesive agent, further strengthening bond strength while helping avoid loosening over time; and making the crown more resistant against abrasion and staining.
Comfort
Zirconia crowns allow natural light to pass through them, creating an even more natural look in your smile. Furthermore, these crowns are highly stain-resistant – meaning there won’t be any discoloration from foods and beverages you enjoy!
Zirconia crowns are much lighter in density than porcelain crowns, making them easier to place on teeth with greater flexibility – something especially valuable in front teeth restoration work. This helps prevent discomfort in jaw areas or other parts of the mouth while making dental work much simpler to complete with less effort needed on your part.
Patients often opt for zirconia crowns due to their ease of placement. The process for placing one is similar to having dental fillings done: your dentist will first remove any decayed areas before shaping and shaping the area accordingly before cementing in place the crown and making any adjustments as necessary for your bite.
Zirconia crowns are stronger than porcelain fused to metal crowns while still requiring less tooth reduction during placement, enabling dentists to preserve more natural teeth while helping maintain healthier jaw structures. Zirconia crowns also look better without visible metal lining at the gumline like their porcelain counterparts do.
Zirconia crowns come in two main varieties: monolithic and layered. Solid zirconia crowns are composed of one solid piece of material and offer greater durability with less risk of fracture compared to their layered counterparts; solid crowns may also be more aesthetic when used on posterior teeth. Layered zirconia crowns consist of multiple ceramic layers bonded onto their zirconium substructure for greater resilience than solid crowns while providing aesthetic enhancement and stimulating healthy tissue responses.
Care for a zirconia crown will extend its lifespan for life if properly maintained. Brush, floss and visit your dentist on an ongoing basis in order to keep it in great shape; during each appointment your dentist will check it for signs of wear or replacement as required.
