A bridge allows the dentist to replace lost teeth without the use of a denture or dental implant. Basically a false tooth is held in place by being attached to a tooth next door. The disadvantage is that the teeth next to the space have to be prepared in a similar way to a crown in order to accept the bridge. If these teeth already have crowns or big restorations then this is not a problem, the major concern however is when these teeth have small or no restorations (fillings). One compromise is the 'acid etched bridge', with this type a fine ledge is placed on the back of the adjacent teeth. This kind of bridge is called a Maryland Bridge The principal technique used to get bridgework to look natural is the ovate pontic. This is a technical term for a method of creating the illusion that the tooth is growing out of your gum. The site where the false tooth is placed can be sculpted with an electrosurgical device prior to placing it, or it can be shaped by augmenting and reshaping the temporary pontic made of acrylic or a composite.This technique is usually performed in the implantoprosthetic treatment . This creates the illusion that the tooth is growing up from the ridge. Porcelain fused to metal crowns (PFM crowns) have a nearly natural appearance, subject to two limitations: Because they have a metal substructure, they require the use of an opaquer under the porcelain, which makes it impossible to re-create the translucency of natural teeth. They can show a dark line at the edge of the crown, next to the gum. Sometimes the line doesn't show when the crown is first placed but shows later, as the gum recedes. PFM crown is stronger than the All Porcelain Crown. All Porcelain Crown is a crown that would not have a metal substructure under it. The reasons for wanting to eliminate the metal are primarily to get rid of the dark line at the very edge of the crown and to let more light pass through the porcelain to look more lifelike. They are the closest thing to the ideal enamel replacement that modern dentistry has yet invented. Over the last few years, new technology has made dental porcelain more practical. Until now, porcelain coated ceramic copings has been neither strong enough nor durable enough for widespread use. Procera All Ceram combines excellent and profound strength with beautiful esthetics. The material consists of 99.5 percent pure aluminum oxide and is biocompatible, thereby ensuring excellent long-term esthetics. Procera All Ceram is translucent giving the tooth a natural appearance. At the same time Procera All Ceram is excellent for concealing underlying surfaces, such as amalgam and root fillings. This ceram is also customized but still industrially produced, ensuring predictable results. With the strength in the core material, Procera All Ceram can be recommended for prosthetic reconstructions anywhere in the mouth. More and more patients are asking for constructions made of material not containing metal or other alloys. Procera All Ceram is made of bio-compatible material (comparable to Titanium) which minimizes the risk of allergic reactions. No need to worry about your allergies when you use Procera All Ceram. The translucent coping offers remarkable esthetic characteristics. When combined with Procera All Ceram Porcelain the advantages are clearly demonstrated. To recreate the beauty of your natural teeth, the porcelain has been formulated to make the most of the coping’s inherent potential and efficiency. Procera ® Crowns come in various materials such as alumina and zirconia. Procera Crowns are customized but still industrially produced, ensuring predictable results. With Procera Crowns, you also get the benefit of translucency, giving the restoration a natural appearance. Procera Bridges Stronger than metallic materials, Procera Bridge Zirconia is a two-to-four unit bridge that can be used in and part of mouth.It is especially appropriate as an esthetic solution in the anterior. Our surgery utilize DCS Precident System as well, since this technology can produce a bridge with more than 4 units. It is also all ceram system very similar to Procera.
Procera Implant Bridge The Nobel Biocare Procera® Implant
Bridge consist of the one-piece machined
titanium substructure and the carbon-fibered framework unit. The machined
framework is made from a pattern that is scanned using a special scanner at the
Nobel Biocare manufacturing facility. The scanner data of the framework pattern
design and the data scanned from the individual implant platforms are
transferred to the computer where the one-piece framework design is finalized and
prepared for machining at the manufacturing facility. The one-piece framework
designs can be created in a form that permits the development of individual
tooth units or of a bar design that will be incorporated into the acrylic resin
denture base of a fixed implant supported prosthesis. When the machining of the
framework has been completed it is returned to the laboratory of origin for
application of low fusing porcelain creating individual teeth that will appear
to emerge from the implants at the fixture level or the framework is prepared
for inclusion in the waxed denture base as the supporting substructure that may
attach to the implants directly or to one of the several Nobel Biocare implant
abutments. The carbon-fibered or a high quality acrylic framework is one that
can be made by the technician in the laboratory. The technician forms the
framework to abutment components on the master cast using special attachments
produced for this framework by Nobel Biocare. Once the technician has developed
the framework design and form, the master cast and carbon-fibered framework is
placed into an oven for polymerization. After curing, the framework can be
finished with dental burs to its final form. The framework is incorporated into
the acrylic resin denture base of the final prosthesis.
"All-on-4" for edentulous jaws is an exciting treatment procedure that take advantage of the benefits of tilting posterior implants. This facilitates an optimal prosthetic support for a high pressure modeled acrylic bridge that can be fabricated and functioning within just a few hours after surgery. The protocol utilizes a simple guide for predictable and optimal positioning of four implants (six implants, if necessary, in the maxilla). "All-on-4" is based on Nobel Biocare's pioneering Immediate Function™ capability.
