Maryland Bridge

The Maryland Bridge is less invasive for single tooth replacement than conventional bridgework, and enables the dental practitioner to splint or replace missing teeth esthetically, with minimal tooth modification. It offers greatly improved bond strength over earlier perforated resin-bonded retainers.

New materials and techniques allow for better retention resulting in the convenience of a fixed restoration at a lower cost. 100% high strength Zirconia Maryland bridges offer ideal esthetics, maximum strength and durability with CAD/CAM precision fits.

A major appeal of this type of bridgework is that adjacent teeth do not require over-prepping. Neighboring tooth structures are not shortened to accommodate an anchoring crown that supports the bridge unit.

Maryland Bridge Advantages

Minimally Invasive: Less aggressive than a three unit bridge
Proven Effective
Over 20 years of clinical success
Cost Effective
Durable with exceptionally strong flexural strength

Maryland Bridge Indications

Single Tooth (Sometimes used for 2 to 3 teeth)
Typically Used for Anterior Cases
Minimum 1 mm clearance from

The Captek™ crown represents an alternative to a conventional cast metal PFM restoration. This unique high noble, rich yellow colored coping is manufactured via a patented technique and formulation utilizing capillary action and infusion to create a thin, high strength metal substrate. This technology combined with high strength ceramic materials and our experience enables us to offer you and your patient a conservative, strong, and highly esthetic restoration.


Excellent Esthetics / No Gray Line at the Margin
Conservative Tooth Preparation / Less Tooth Reduction Required
Clinically Proven Biocompatibility
Minimizes Bacterial Build-up / Leads to Healthier Periodontal Tissue
Highly Accurate Internal Fit and Marginal Integrity
Convenience of Cementability

Recommended Preparation Type

Conventional crown and bridge preparation techniques are acceptable.

Recommended Incisal/Occlusal clearance measurement

Superior esthetics can be accomplished at 0.8-1.0mm facial reduction on anterior crowns when typical reduction is not possible and the routinely recommended 1.5-2.0mm of occlusal clearance for posterior crowns.

Recommended Cement and Technique

Any crown and bridge cement can be used. The best bond strength is accomplished with Panavia or Meta Bond C&B.

Porcelain Fused to Metal

PFM crown and bridge restorations offer the ideal combination of durability and esthetics for long-lasting restorations. Available in a wide range of options for every indication, PFM metal-ceramic solutions have stood the test of time, bringing unsurpassed strength and durability to the realm of dental restorations. Porcelain-fused-to-metal restorations have been a mainstay of prosthetic dentistry for more than half a century. PFMs work well as single units and bridges designed by your preferences for each case. Ezcad Dental Lab offers the best crown and bridge restorations in PR.

IPS e.max®

IPS e.max combines high esthetic vitality with high performance. This innovative lithium disilicate ceramic fulfills the highest esthetic demands and unites state-of-the-art technology with exceptional user friendliness. IPS e.max is a lithium disilicate glass ceramic with optimized translucency, durability and strength for full anatomical restorations. IPS e.max is available as a pressed and as a CAD/CAM milled technology.

Available in full contour monolithic or cut back and multi-layered, IPS e.max lithium disilicate ceramic is our choice for single anterior/posterior crowns, 3-unit anterior bridges (bicuspid forward), veneers and inlay/onlays as it truly mimics the light refraction and natural translucency necessary for outstanding esthetic appearance. With two times the strength of the original IPS Empress and the maximum benefits of a monolithic structure, IPS e.max is the material of choice for minimally invasive esthetic dentistry.

Layered High-Strength Zirconia

Our Classic Porcelain-Fused-to-Zirconia possesses both the translucency of porcelain and the durability of zirconia. Our Layered Zirconia product uses a cutback design on Sagemax NexxZR S hi-strength Zirconia and is layered with Vita VM9 porcelain higher esthetics. By layering highly esthetic porcelain on a resilient zirconia substructure, our Layered Zirconia fixed restorations offer a naturally lifelike restoration not found in traditional porcelain-fused-to-metal restorative products

Layered High-Strength Zirconia Advantages

Excellent shade reproduction and wear-kind to opposing dentition
High biocompatibility for improved tissue health and for patients with metal sensitivity
No black lines or gingival graying. Semi-transparent with a high opacity to mask underlying tooth discoloration, metal cores and implant abutments
Reduction in seating time due to precise CAD/CAM internal fit and contact adaptationUse your preferred cementation material and protocol

Katana™ aesthetic zirconia is manufactured by one of the top porcelain companies in the world, Noritake. What is amazing about this aesthetic zirconia by Katana™ is the highly aesthetic results it can produce. The Katana™ zirconia disc is multi-layered which helps achieve a natural tooth appearance.

Katana™ zirconia has incredible strength (1200mpa), and still has a translucency like no other, getting impeccable results and has an advantage as a full contour zirconia crown versus a porcelain fused restoration. Katana™ contains an enamel layer, a first transition layer, a second transition layer, and finally a body layer. This leaves no issues while adjusting the crown, whereas a typical zirconia crown, that are dipped and stained, the shade could easily be removed while adjusting with a bur.

Katana Advantages

Strength: Zirconia crowns will outlast all other types of crown (this is the same material used in hip and knee replacement procedures).

Appearance: Crowns made with Katana Zirconia ML also happen to offer translucency solutions comparable to any other alternative on the market.

Minimal Invasiveness: Less preparation and impact to site means more of the original tooth is preserved.

Solid Full Contour Zirconia

Our Full Zirconium oxide material has very high strength and corrosion resistance. With zirconium crown techniques, we can also eliminate the problem of exposed metal crown margins in the older, porcelain-fused-to-metal technique. The zirconium crown has a beautiful white frame, which replaces the normal metal or gold frames.
The material is bio-compatible with human tissues and does not cause allergies which can occur (although not often) with metal-based crowns.

It has excellent aesthetic qualities due to the absence of metal. Metal content in porcelain crowns can cause small aesthetic imperfections resulting from transparency and light refractability. The crowns are made with precision accuracy, with the help of a laser scanner and a computer and five axis milling machines. Hygienically, the zirconium crowns retain less plaque and calculus than base metal frame crowns, promoting healthier gums.
