The unsightly appearance of the classic cases (gum gray, bulky, etc.) can be treated effectively with new porcelain cases. Replacing them with new all-ceramic porcelain cases restores health and offers naturalness and confidence. Thus, a remarkable change is achieved in the shape, location and color of restorations with new dental porcelains, which do not require metal-free prostheses,
Porcelain Cases - What It Is
The crowns or, in the so-called porcelain cases, are full coverage crowns that fit and hug the tooth tightly. They have the shape, size and color of natural teeth. Porcelain cases are placed on teeth, whose structural strength have been degraded, and protect them against a possible fracture.
They are solid restorations of total coverage (all the surface of the tooth is rubbed) as opposed to the porcelain resin faces and the inserts / overlays, which are partial restoration restorations. Cases are made for both natural teeth and dental implants (see implant holes)
Elements of choice for their manufacture are ceramic materials of excellent zirconium oxide (Katana Inc), or all-ceramic crown ips e.max, whose optical and mechanical properties are unmatched.
The new zirconia materials, introduced in recent years, support the construction of CAD / CAM restorations and offer improved optical properties (transparency, opalisation) that make them the choice materials for hoops and bridges.
All-ceramic Porcelain Cases - Advantages
- More biocompatible than classic metallic crowns (cases) - perfectly tolerated by the gums
- Unparalleled aesthetics compared to classic metal chips
Porcelain Cases or Faces?
Restorations of partial tooth cover (porcelain facades, overlays) are much more conservative than total cover restorations (holes, pockets, bridges), and are therefore preferred over pockets and bridges
With the development of adhesive systems for facades and porcelain (partial covering restorations), the use of crown-cases (total coverage restorations) is limited to very specific cases, such as:
- in teeth that have lost all their walls (up to 2 mm clinic height)
- or that already have failed hoops.
A basic requirement for placing a successful crown is the presence of at least 2 mm of ferrule effect. Otherwise, aesthetic elongation of clinical mucosa (oesoplasty-osteoplasty) or orthodontic sunrise
PORCELINE ZIRKONI BRIGDES
Porcelain Bridges - When Used
When one or more natural teeth have been lost, a prosthetic restoration (bridge) can be made, which is attached to the adjacent teeth and replaces the missing teeth. It is a prerequisite for the teeth to be healthy and quite numerous
A bridge essentially consists of pockets, which are built next to each other and which are joined together.
Bridges are also made on dental implants when there are no teeth.
Porcelain Bridges For Rear Teeth
In recent years, by improving the optical properties of zirconia (zirconia), which is a ceramic material of exceptional strength, zirconia bridges are our first choice.
The metallic ceramic bridge, which is also the most common prosthetic solution, consists of a metal skeleton (either chromium-cobalt alloys or noble metal alloys - platinum / platinum), which is coated with dental porcelain.
Porcelain Bridges For Forward Teeth
In anterior teeth aesthetic requirements are increased. Bridges for the anterior area - aesthetic zone - are made of zirconium oxide, or all-ceramic systems Empress II, ips e.max, whose optical properties are unmatched.
Porcelain Bridges - Application Accuracy and Aesthetics
The new all-ceramic systems (zirconia and e-max) support the construction of prosthetic restorations with the use of digital imprinting and construction - CAD / CAM Construction stages - Times The stages of construction of a tooth-based bridge include the following
- the preparation (i.e., grinding) of the teeth-supports
- construction and installation of the temporary bridge
- construction of rehabilitation
- and its final bonding to teeth supports.
For building a bridge, 2-5 sessions are required and a total time of 7-15 days (depends on the size of the restoration).
The final cost is not burdened by the number of sessions, depends on the construction material and the number of missing teeth and is clarified at the first session.
Bridge or implant?
A disadvantage of dental bridges is the tooth-tooth grinding.
Therefore, a dental bridge should not be our first choice, as there are now much more conservative solutions. The predictable use of implants is considered to be a completely conservative choice and is preferred over dental bridges. Implants have restricted the choice of bridges only in those cases where implants can not be placed. Additionally, placing an implant is a more cost-effective solution if you consider the cost of treating a tooth-to-brace of a bridge (endodontic treatments-intralineal axes, transient restorations, etc.)
