Zirconia Crown Comparison: Bruxzir vs 3M vs Emax Explained

Choosing the right dental crown can be overwhelming, given the myriad of options available. Zirconia crowns stand out for their strength, durability, and aesthetic appeal. Yet, it's important to recognize that not all zirconia crowns are the same.

This article will compare three leading zirconia crowns: Bruxzir, 3M, and Emax. Understanding their differences will empower you to make a choice that aligns with your dental needs and preferences.

Zirconia crowns have transformed dentistry, offering a dependable alternative to traditional porcelain-fused-to-metal (PFM) crowns and other ceramics. Their monolithic structure, a single solid piece, minimizes the risk of bond failure and porcelain chipping, ensuring reliability for long-term use.

But how do Bruxzir, 3M, and Emax zirconia crowns differ? We'll delve into the specifics of each to assist you in finding the perfect match for your dental care.

Bruxzir Zirconia Crowns


Overview and Composition

BruxZir Zirconia crowns represent a pinnacle in monolithic zirconia restoration, crafted from a singular, solid piece of zirconia material without any porcelain overlay. This unique composition is vital for their renowned durability and strength. The zirconia utilized is infused with yttria, significantly boosting their mechanical properties to align with the ISO strength recommendations for dental restorations.

These crowns are designed for excellent strength, aesthetics, and performance, making them ideal for a variety of clinical applications such as crowns, bridges, and implant restorations.

Advantages

The exceptional strength and durability of BruxZir Zirconia crowns are among their primary benefits. They have demonstrated zero terminal fractures in long-term clinical studies, underscoring their reliability for demanding restorative cases. Moreover, BruxZir crowns have evolved to offer improved translucency and color consistency, enhancing their suitability for anterior cases where a natural appearance is paramount.

Compared to other materials like IPS e.max and Ceramco 3, these crowns are also less abrasive to the enamel, which helps in preserving the health of adjacent teeth. The absence of metal in their composition significantly reduces the risk of allergic reactions and soft tissue irritation, presenting an excellent choice for patients with material sensitivities.

Additionally, the ease of preparation and cementation protocols of BruxZir crowns allow for minimal tooth reduction and offer various cementation methods, further contributing to their appeal.

Limitations

Despite the numerous advantages, BruxZir Zirconia crowns have some limitations. Their cost is higher than traditional PFM crowns, but many find the investment justified by their superior durability and aesthetic outcomes. The specific preparation requirements, including particular margin designs and minimal occlusal reduction, may necessitate more precise dental work, potentially increasing the overall cost and complexity of the procedure.

Although BruxZir Esthetic zirconia has achieved remarkable progress in lifelike translucency, it might not perfectly mimic natural teeth in every case, especially in highly aesthetic anterior restorations. However, advancements in shading technology have greatly enhanced the shade matching and consistency of these crowns.

3M Lava Zirconia Crowns


Overview and Composition

3M zirconia crowns, particularly those under the Lava and Chairside Zirconia brands, are engineered to balance strength, aesthetics, and efficiency. These crowns are made from polycrystalline zirconia, stabilized with yttrium oxide, which enhances their mechanical properties.

The composition of 3M zirconia crowns includes a mix of tetragonal and cubic crystal phases. For instance, 3M Lava Plus Zirconia is predominantly tetragonal, providing high strength but lower translucency, while 3M Lava Esthetic Zirconia has a higher percentage of cubic phase crystals, increasing its translucency to 40%.

The 3M Chairside Zirconia, a more recent development, contains 4% yttria, resulting in a phase composition of approximately 75% tetragonal and 25% cubic. This balance allows for high strength (1000 MPa flexural strength), good translucency, and reduced sintering time, making it suitable for single-visit appointments.

Advantages

One of the key advantages of 3M zirconia crowns is their exceptional strength and durability. The high flexural strength, particularly in the Lava Plus and Chairside Zirconia, ensures that these crowns can withstand the rigors of daily chewing and biting forces.

Additionally, the optimized crystal phase composition in these materials enhances their resistance to wear and fracture toughness.

The aesthetic appeal of 3M zirconia crowns is also noteworthy. The Lava Esthetic and Chairside Zirconia offer improved translucency, which helps in achieving a more natural appearance. These crowns come pre-shaded to match the VITA classical shade guide, making it easier to match the patient's tooth shade.

Another significant advantage is the efficiency and speed of the process. 3M Chairside Zirconia can be fast-fired in high-temperature sintering furnaces, reducing the sintering time to approximately 20 minutes for thin-walled crowns. This allows for single-visit restorations, enhancing patient satisfaction and practice efficiency.

Limitations

While 3M zirconia crowns offer numerous benefits, there are some limitations to consider. The higher cost compared to traditional dental materials can be a significant factor for some patients. Additionally, the need for specialized milling and sintering equipment can add to the overall expense and complexity of the procedure.

Although the translucency of 3M zirconia crowns has been improved, they may still not perfectly match the natural teeth in highly aesthetic cases. However, advancements in shading technology and the use of dyeing liquids have significantly enhanced the aesthetic outcomes.

E-Max Zirconia Crowns


Overview and Composition

Emax crowns, made from Lithium Disilicate glass, represent a distinct category within the realm of dental restorations. Unlike zirconia, which is a metal oxide ceramic, Emax crowns are composed of a glass-ceramic material.

This composition includes lithium disilicate, which provides the crowns with their unique properties. Emax crowns can be either monolithic or layered, with the latter involving a porcelain overlay to enhance aesthetics. The manufacturing process for Emax crowns typically involves CAD/CAM technology, where the crown is milled from a disc of lithium disilicate material. This process allows for precise fitting and minimal tooth reduction, often as little as 1.5 mm, making it a conservative approach that preserves more of the natural tooth structure.

Advantages

One of the primary advantages of Emax crowns is their exceptional aesthetic appeal.

They offer superior translucency compared to zirconia, making them highly suitable for anterior restorations where natural appearance is important. The ability to layer porcelain on Emax crowns further enhances their aesthetic properties, allowing for a very realistic and lifelike appearance that closely matches the patient's natural teeth.

Emax crowns are also known for their biocompatibility and safety.

They do not cause allergic reactions or irritation, making them an excellent choice for patients with sensitivities. Additionally, Emax crowns are durable, with a flexural strength of 380-500 MPa, which is sufficient for most clinical applications, especially in the anterior region where forces are generally lower.

The comfort and functionality of Emax crowns are also noteworthy.

They are designed to restore the natural functions of the teeth, providing excellent chewing and biting capabilities. The anatomical shape and precise fitting ensure a correct bite and comfortable chewing experience.

Limitations

Despite their many advantages, Emax crowns have some limitations. One of the main drawbacks is their relatively lower strength compared to zirconia crowns.

While they are suitable for anterior teeth and cases where aesthetics are paramount, they may not be the best choice for posterior teeth that are subject to higher chewing forces. In such cases, zirconia crowns might be more appropriate due to their higher strength and durability.

Another limitation is the potential for Emax crowns to fracture under extreme forces. Although rare, this can occur, especially if the crowns are subjected to heavy grinding or biting forces.

However, with proper care and maintenance, Emax crowns can last for over 15 years, preserving their original properties and appearance.

Finally, Emax crowns tend to be more expensive than zirconia crowns, which can be a significant factor for some patients. However, the superior aesthetic results and the ability to achieve a highly natural appearance often justify the additional cost.

Conclusion

In conclusion, selecting the ideal zirconia crown for your dental requirements necessitates a thorough evaluation of various factors. Brands like BruxZir, 3M, and Emax each bring distinct benefits to the table, ranging from exceptional strength and durability to superior aesthetics.

BruxZir crowns are renowned for their robustness and minimal tooth reduction, whereas 3M crowns offer a balance between strength and enhanced translucency. Emax crowns, although not made of zirconia, are celebrated for their excellent aesthetic results and biocompatibility.

When choosing a crown, it's important to consider your specific needs, the location of the tooth, and the desired aesthetic outcome. By comprehending these differences, you can make a well-informed decision that guarantees satisfaction both functionally and aesthetically.

How to improve your margins and digital dental scans

By Sarfraz Ahmed

 

Excellent margins are vital for attaining a well-becoming healing requiring minimum chair-facet adjustments. It is essential to make certain the margins are designed and prepped correctly, and afterward, it’s miles first-class to shine your prep. Your preference of margin training relies upon at the kind of crown decided on for the affected person. The forms of margins and whilst to apply them are mentioned beneath.

 

Dental Margin ms dental arts

 

 

Knife-part or feather-part margins are appropriate for:

Full-solid crowns.

Full zirconia crowns.

Less teeth discount is needed with a knife-part or feather-part margin, however, this training is much less perfect for layered Zirconia restorations and can purpose becoming issues.

 

Dental Margin ms dental arts

 

 

Bevel-chamfer margins are appropriate for:

Full-solid crowns.

Full zirconia crowns.

PFMs.

Bevel-chamfer margins provide a higher marginal in shape, and there may be much less risk a darkish line may be seen on the margin. This margin training isn’t an premiere preference for layered zirconia or IPS e.max crowns.

 

 

Chamfer margins are appropriate for:

Full-solid crowns

Full zirconia crowns

Chamfer margins offer a greater passive and higher marginal in shape without a darkish margins. They are much less appropriate for layered zirconia and IPS e.max restorations.

 

 

 

Shoulder or butt-joint margins are appropriate for:

Full-solid crowns.

Full zirconia crowns.

Layered zirconia.

IPS e.max.

Shoulder or butt-joint margins offer a greater passive in shape and put off darkish margins. This training is suggested for LiS2 and layered zirconia. Care ought to be taken to make certain right isolation of the margin all through training.

 

 

Shoulder-bevel margins are appropriate for:

Full-solid crowns.

Full zirconia crowns.

Shoulder-bevel margins assist make certain a greater passive and right marginal in shape, getting rid of darkish margins. They aren’t a premiere preference for layered Zirconia crowns, and right margin isolation is vital all through training.

Isolating the margins is vital for a well-becoming crown. If your dental lab can not see the margins of a traditional influence or if a virtual scanner fails to choose up the margins satisfactorily, there may be a excessive hazard the case may be delayed,  in particular if the influence is rejected. Otherwise, if the case is going ahead, it may bring about open or quick margins. For those reasons, increasingly more clinicians are selecting to apply virtual impressions.
Digital generation permits records to be captured and visualized, offering the possibility to investigate tiny information which aren’t effortlessly seen on traditional tray impressions.

 

How to Get a Great Margin Scan on Your iOS

Although virtual impressions can offer precise images, there are numerous critical elements to consider.

 

Obtaining a Sub-Marginal Line of Sight with Accuracy

The picture displayed withinside the replicate is the picture so that it will be captured with the aid of using the scanner, and ideally, it have to display 0.5mm sub-marginally. Dental labs regularly obtain virtual impressions in which moisture and tissue had been inadequately controlled. Although the margin is seen, it isn’t truly defined. Keep in thoughts that virtual scanners best seize the picture this is seen; the conventional influence method can bodily pressure a few tender tissue out of the manner, as low viscosity fabric is injected into the sulcus. Your techniques, whilst making ready for a virtual influence, ought to will let you visualize the sub-marginal line of sight truly.

 

Retracting Soft Tissue

Retracting tender tissue is first-class completed with the aid of using packing a wire into the sulcus earlier than taking the influence, however this assignment is frequently less difficult stated than done. Inflamed gingival will regularly bleed, and setting apart the margins is difficult whilst area is limited. Supragingival margins provide a clearer visualization, however frequently enamel which might be being prepped for a crown can have formerly been restored with sub-gingival margins, and the fitness of the gingival tissues is regularly compromised.

Usually, as a minimum a part of the training is beneath the loose gingival margin. If your teeth training has subgingival margins, the tissue ought to be separated from the training part, permitting an awesome best virtual test. A excessive-readability test is completed with top notch best retraction, revealing a clean margin.

 

 

Exposing Margins with a Soft Tissue Laser and Retraction Paste

Using a tender tissue laser may be beneficial for exposing sub-gingival margins and for getting rid of dangerous and infected gingival tissue that can be masking the margin or growing immoderate bleeding. Removing infected tissue additionally allows to stimulate the regrowth of more healthy tissues. After treating regions with a dental laser, peroxide answer eliminates tissue debris. More fairly infected regions may be handled with a retraction paste that allows to offer hemostasis and bodily separation among the margin and tissue. The paste is injected into the sulcus, and a company cotton roll is located over the paste. The affected person bites down at the cotton for among and 5 mins, after which period the paste is rinsed away leaving a clean view of the margin.

 

Using a Retraction Cord

A retraction wire movements gingival tissue out of the manner of the margin arrangements and is inserted lightly beneath the gum line and into the gingival sulcus across the teeth. Using a retraction wire can displace gum tissue effectively,  but it’d additionally purpose bleeding. This bleeding can be complicated to control, making it awkward to seize the margins truly. Some forms of wire are already soaked in an answer of hemodent or may be soaked with the aid of using the clinician earlier than placement.

 

Using the Double Cord Method

It’s additionally feasible to apply the double wire method; the usage of a double wire can beautify tissue displacement, and margins are higher defined. One trouble with the usage of a unmarried wire is that frequently margin regions are extraordinarily skinny and impressions can greater without problems deform. If the affected person has an in particular deep sulcus, the usage of cords prevents tissue from collapsing over the pinnacle of the wire. When packing the cords, % a small wire at once beneath the margin of the teeth, and % a bigger wire at once on pinnacle of the small wire. The huge wire is left in region for as a minimum 5 mins earlier than being removed. You can then determine whether or not to get rid of the small wire earlier than the influence is taken or to go away it in region.

The accurate margin training and tissue control strategies are important to the whole system of fabricating and becoming a top notch restoration, whether or not the use of a traditional or virtual impression.

How to make a dental crown fit properly

By Sarfraz Ahmed

Palo Malo with DMLS Crown
Palo Malo with DMLS Crown

The methods used in clinical and laboratory settings for crown fitting are widely known. It is necessary to transmit clinical data from the oral cavity to the laboratory and back again. Clinical and/or laboratory processes could have led to crowns that don’t fit properly. Both sides of the spectrum require a high level of quality control. Crown seating procedures must to be dependable and consistent.

The difficulty with loose-fitting crowns is typically locating the precise point of contact so that an adjustment can be made. Adjusting the crown by guesswork or eyeballing takes time and does not always result in a perfect fit. Unacceptable crowns that don’t fit properly shouldn’t be cemented.

In three sections, this article outlines the clinical and laboratory perspectives on crown procedures:

Part I: Seating Crowns as Recieved from MS Dental Arts Lab

Part II: Potential Roots of Poor Crown Fit

Part III: Clinical Treatments for Dislodged Crowns

Part I: Seating crowns as they were delivered by MS Dental Arts Lab

Lab procedures:

  • Check the crown both on the die by itself and on the mould. Magnification is advantageous. The die’s margins and the crown margin should line up perfectly.
  • Put the crown on the die and the die into the cast. It ought to be simple to slide into position. The interproximal connections are AREAS, not points, keep that in mind. The middle third of the axial walls and the middle to buccal thirds buccal/lingually should be the areas of contact. Contact Areas for Dental Crown Margins
  • Close the upper and lower articulator components to assess the occlusion. Articulating paper should fit snugly between each tooth.

Clinical actions

  • Clean the prep of cement and dirt after removing the temporary crown. Try it in the crown; if it doesn’t sit all the way down, test the interproximal contacts with floss. Adjust as necessary until the crown is properly seated. In order to verify seating, take a bitewing radiograph.
  • Examine the occlusion; the crown’s occlusal surface should not be “high.”
  • Permanent cement is polished into the crown.
  • Remove any extra cement:
  1. If unsure of whether all cement has been removed, another radiograph may be required.
  2. Check the occlusion once more.
  3. Present the patient with the crown.

Part II: Potential reasons why crowns don’t fit properly

Micro-leakage: When the luting cement used to secure the crown to the tooth structure dissolves, micro-leakage results. As a result, there is a small flaw between the preparation and the crown.

Cementation: Crowns that have not been properly cemented run the risk of coming loose if the manufacturer’s recommendations are not followed or the cement is improperly mixed.

Tooth Decay: If not kept clean, restored teeth are more prone to plaque buildup and caries. This may eventually result in tooth decay underneath the crown.

Bruxism: By dislodging or fracturing the cement, bruxism, or grinding your teeth, can loosen crowns.

Diet: Taffy and other sticky foods, such candies, can entirely dislodge crowns.

Note: Every effort is made to verify that all crowns fulfil laboratory requirements using MS Dental Arts Lab quality control methods. Before packaging, all crowns will fit the dies and/or casts appropriately. Crowns that don’t fulfil these requirements won’t be given back to doctors.

Part III: Medical solutions for loosened crowns

  • Analyze the preparation and the crown. With the aid of hand tools, steam cleaning, or air particle abrasion, remove any dirt that is inside the crown.
  • Reposition the crown onto the preparation and assess the integrity of the margin. To assess subgingival regions, do a bitewing radiograph. If everything is in order, just re-ceil the crown. It is recommended to get the dental crown made again if it is loose because of tooth decay apical to the borders.

Zirconia crowns being re-cemented

  • Change your cementation procedure if your zirconia crowns are debonding or coming loose. Before polishing the tooth with pumice, the majority of dentists test the zirconia crown’s comfort in the patient’s mouth.
  • If the cement does not include a built-in primer, proceed by decontaminating the intaglio surface of the zirconia restoration before preparing it with a priming agent or adhesive. Since light does not reliably penetrate zirconia, the cement should be dual-cured (light and chemical).
  • The crown should next be cemented and light-cured from various angles in accordance with the manufacturer’s recommendations. As above, scrape away any extra cement.
