Crowns
If you want a smile that's your crowning glory, you may need a crown to
cover a tooth and restore it to its normal shape and size. A crown can
make your tooth stronger and improve its appearance.
It can cover and support a tooth with a large filling when there isn't
enough tooth left. It can be used to attach a bridge, protect a weak
tooth from breaking or restore one that's already broken. A crown is a
good way to cover teeth that are discolored or badly shaped. It's also
used to cover a dental implant.
A
crown, or full-coverage restoration (sometimes incorrectly called a cap)
is a prosthetic tooth designed by a dentist and usually created by a lab
technician (or more recently, a CAD-CAM machine). Crowns can be either
metal, porcelain fused to metal (PFM), or all porcelain/ceramic. Metals
can either be noble metals ,base metals or recently titanium, noble
metals having higher content of gold, platinum or palladium. All
porcelain restorations can be made from feldspathic (traditional)
porcelain, lithium disilicates, aluminous porcelains, or zirconia.

Bridges
If you're missing one or more teeth, you may notice a difference in
chewing and speaking. There are options to help restore your smile.
Bridges help maintain the shape of your face, as well as alleviating the
stress in your bite by replacing missing teeth.
Sometimes called a fixed partial denture, a bridge replaces missing
teeth with artificial teeth, looks great, and literally bridges the gap
where one or more teeth may have been. The restoration can be made from
gold, alloys, porcelain or a combination of these materials and is
bonded onto surrounding teeth for support.
Home oral hygiene for most patient is a challenge.
Given time, use and the hostile oral environment all dental restorations
will eventually need replacement. A dental bridge is fabricated by
reducing the teeth on either side of the missing tooth or teeth by a
preparation pattern determined by the location of the teeth and by the
material from which the bridge is fabricated.
Partial and Full Dentures
If you’ve lost all of your natural teeth, whether from periodontal
disease, tooth decay or injury, complete dentures can replace your
missing teeth and your smile. Replacing missing teeth will benefit your
appearance and your health. Without support from the denture, facial
muscles sag, making a person look older. You’ll be able to eat and
speak—things that people often take for granted until their natural
teeth are lost.
Dentures (also known as dental plates), can be defined as a set of
artificial teeth, which are used when a patient has lost real teeth on
the mandibular arch (lower jaw), the maxillary arch (upper jaw), or
both. Patients can become entirely edentulous (without teeth) due to
severe malnutrition, genetic defects such as Dentinogenesis imperfecta,
ineffective oral hygiene or trauma. Dentures can help give the
edentulous patient only limited masticatory (chewing) abilities, as well
as enhance the aesthetic appeal of their lips in specific and their
entire face in general.
There are various types of complete dentures. A
conventional full denture is made and placed in the patient’s mouth
after the remaining teeth are removed and tissues have healed which may
take several months. An immediate complete denture is inserted as soon
as the remaining teeth are removed. The dentist takes measurements and
makes models of the patient’s jaws during a preliminary visit. With
immediate dentures, the denture wearer does not have to be without teeth
during the healing period.
Removable partial dentures are for patients who are
missing only some of their teeth on a particular arch (upper jaw or
lower jaw or both).
