Retrievable, cement-free and durable. Screw-Retained Implant Crowns are a convenient, hygienic and predictable restorative option. Easily removed without damage to the crown, screw-retained implant crowns provide convenient access for restoration cleaning, replacement of prosthetic screws, and assessment of the soft tissue and adjacent teeth. They are the optimal choice in clinical situations where limited interocclusal clearance is a factor or residual cement is a concern. Constructed from monolithic solid zirconia with a titanium base connection, screw-Retained Implant Crowns offer exceptional fracture resistance and esthetics, and are the perfect fit for a wide variety of challenging prosthetic circumstances.
Surgical Implant Guide
The surgical guide may rest on the teeth, gingiva, or bone. The Sirona Surgical Guide has stops that limit the depth of the drill and limit the depth of the implant. A successful implant restoration is dependent on proper position. Correct implant placement is more predictable when a surgical stent is used.
All on 4 Dental Implants
This especial treatment concept is a cost-efficient, graftless solution that provides patients with a fixed full-arch prosthesis on the day of surgery. Characteristics include: Full-arch rehabilitation with only four implants. Two straight anterior implants and two implants tilted up to 45º in the posterior.
Custom Implant Abutments
Titanium-zirconia hybrid abutments are a unique configuration. They have a titanium interface for the implant plus a cylinder to cement to a custom-milled zirconia abutment “topper”. This type of abutment can provide the mechanical reliability of a titanium-to-titanium interface with the esthetic advantage of a shaded zirconia abutment.
Typically, this is only an option for bone level platforms; otherwise, the titanium-zirconia margin may be visible. Extra space is also needed for this type of abutment to accommodate the titanium collar—at least a minimum thickness of 0.5 mm of zirconia and room to contour a margin for the final restoration.
Designed and milled using CAD/CAM technology, this type of restoration is very strong with 680/ 1100 mpa. Zirconia comes in 16 different vita shades, in a high translucent and Super translucent version for the anterior area. It will not break or crack and its ideal for bruxers and grinders. It is an optimal option to prescribe instead of posterior metal occlusal PFM and full cast metal restoration. Designed specially for the posterior where the occlusal space is limited, but also used now in the anterior area per it’s high translucent appearance similar to Emax crowns.
No matter which technique you choose, all components are available from one manufacturer. If you prefer to work with the PRESS technique, two different types of ingots are available: IPS e.max Press, a high-strength glass-ceramic and IPS e.max ZirPress, an esthetic glass-ceramic which is pressed onto zirconium oxide in a fast and efficient procedure. For CAD/CAM applications, either the highly esthetic IPS e.max CAD ceramic glass blocks or the high-strength IPS e.max ZirCADzirconium oxide can be selected, depending on the case requirements. The nano-fluorapatite layering ceramic IPS e.max Ceram completes the all-ceramic system. This material is used to veneer all IPS e.max components, no matter if they are glass-ceramic or zirconium oxide.
IPS e.max Press are biocompatible lithium disilicate glass-ceramic ingots. They offer the fit, form and function which is expected from pressed ceramics. In addition, they offer improved flexural strength (400 MPa). With optimized esthetic properties creating all-ceramic restorations that offer true-to-nature results has never been so easy.
IPS e.max CAD unites modern processing technology with a high-performance material. The lithium disilicate glass-ceramic is manufactured in an innovative technological process, unique in the dental industry. The glass-ceramic is processed for the laboratory in a crystalline intermediate phase. In this “soft” state, the material exhibits its unusual “bluish” color and strength of approximately 160 MPa. In this “blue” phase, the restorations can be manually adjusted or cut-back in a fast and efficient fashion. IPS e.max CAD acquires its final strength of 360 MPa and the desired esthetic characteristics, such as tooth color, translucency and brightness, during a simple and quick crystallization process.
The popular IPS Empress System is synonymous with utmost esthetics in the restoration of dental defects and continues to set decisive standards as regards esthetics, function and processing. More than 40 million IPS Empress restorations speak for the lasting lifelike appearance, the continuing success and the high quality standard. Since the introduction of IPS Empress CAD, the popular all-ceramic material can now be processed utilizing the CAD/CAM technology.
The IPS Empress glass-ceramic is an extremely homogeneous, leucite-based material that scatters light naturally and provides a balanced chameleon effect. It inspires users with its translucency and lifelike appearance. Since the IPS Empress Esthetic press-ceramic and theIPS Empress CAD machinable ceramic blocks are the same from a materials science point of view, both materials demonstrate excellent strength values of 160 MPa in addition to the light optical properties. The expressive all-ceramic single-tooth restorations such as veneers, inlays, onlays and crowns thus harmoniously blend in with their natural environment. Careful preparation determines the durability and accuracy of fit of the restorations, whereas minimally invasive preparation is gentle to the tooth structure.
- Highly esthetic pressed and CAD/CAM-fabricated restorations.
- Natural chameleon effect for optimum shade match.
- Leucite glass-ceramic proven 40 million times with a flexural strength of 160 mpa.
