A pontic is defined as an artificial tooth on a fixed dental prosthesis that replaces a missing natural tooth, restoring its function and esthetics. Pontics are represented on treatment setups as translucent teeth.
A fixed partial denture is made to fill an edentulous space in the mouth with substitute or false teeth. It is anchored by crowns on either side of the edentulous space. It may include crowns and pontics attached to natural teeth or implants that will retain the prosthesis, filling the edentulous space.
The adjacent teeth, called retainers , are covered by the bridge in exactly the same manner as a crown covers a single tooth . The difference is that the bridge connects the crowns to a pontic (fake tooth replacement) in the missing tooth space.
Prosthodontics is the branch of dentistry that design and implement artificial replacements for teeth and gums. These include fillings, dentures, veneers, crowns, bridges and dental implants and any combination of treatments to restore lost or damaged teeth.
Ante’s law states that “the total periodontal membrane area of the abutment teeth must equal or exceed that of the teeth to be replaced.”1 For more than 80 years, this law has been taught in standard textbooks of prosthodontics as an important condition influencing FDP design.
How Long Do Dental Implants Last? With regular brushing and flossing, the implant screw itself can last a lifetime, assuming the patient receives regular dental check-ups every 6 months . The crown, however, usually only lasts about 10 to 15 years before it may need a replacement due to wear and tear.
Removable partial dentures cost anywhere between $650 and $2,500 (upper or lower, not both). The price of flexible partial dentures ranges from $900 to $2,000 . Flipper teeth cost between $300 and $500. A fixed denture (dental bridge) is the most expensive.
A removable partial denture or bridge usually consists of replacement teeth attached to a pink or gum-colored plastic base, which is sometimes connected by metal framework that holds the denture in place in the mouth. Partial dentures are used when one or more natural teeth remain in the upper or lower jaw.
This is used in the context of a fixed bridge (the ” abutment teeth ” referring to the teeth supporting the bridge), partial removable dentures (the ” abutment teeth ” referring to the teeth supporting the partial) and in implants (used to attach a crown, bridge, or removable denture to the dental implant fixture).
There are several disadvantages to dental bridges . These include: Once the bridge is fitted, the adjacent teeth that hold the bridge in place may become damaged. A risk of decay is present if the crowns over the abutting teeth are ill-fitting (from allowing bacteria and plaque underneath the crowns)
Bridgework usually fails due to decay or leakage under the crowns on the supporting or ‘abutment’ teeth, or sometimes due to fracture of one or more of the ‘abutment’ teeth. If this can be successfully treated and the teeth are still maintainable, new bridgework can be made.
If one implant for each missing tooth isn’t possible, the bridge may have a pontic suspended between two implant-supported crowns. Considered the strongest and most stable system, an implant-supported bridge commonly requires two surgeries: one to embed the implants in the jawbone. a second surgery to place the bridge .
The most affordable tooth replacement solution is dentures. This is because they take the least amount of time to create. There is no surgery and no dental crowns to place . Instead, an impression is taken of the mouth along with measurements.
Loose bridges can often be easily removed and repaired, allowing your dentist to recement the bridge into place. However, the cement used to bond a bridge in place is designed to last for many years and it is not always possible to remove a bridge without causing damage to the support of surrounding teeth.
A dental bridge is a very good idea for replacing a missing tooth. Though it is not the only tooth replacement option available, a dental bridge is a suitable and affordable restorative dentistry for most patients.
