Crowns and Bridges


A crown is a type of dental restoration which completely caps or encircles a tooth or dental implant and is typically bonded to the tooth using dental cement. Crowns can be made from many materials, which are usually fabricated using indirect methods. Crowns are often used to improve the strength or appearance of teeth.     
            
      A bridge, also known as a fixed partial denture, is a dental restoration used to replace a missing tooth by joining permanently to adjacent teeth or dental implants. A 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.     
            
      Crowns and Bridges are applicable in the following :

  • ROOT CANAL TREATED TOOTH : It is important for a root canal treated tooth to have a crown as the tooth though now healthy is brittle (because the nerve and blood supply has been removed). The living tooth structure is surprisingly resilient and can sustain considerable abuse without fracturing. Consequently, after root canal therapy is performed, a tooth becomes extremely brittle and is significantly weaker than its vital neighbors and may be prone for fracture.


  • AESTHETICS :Crown would be the restoration of choice when a patient desires to have his or her smile aesthetically improved. Crowns can alter the size, shape or shade of a patient's teeth while protecting against failure of the restoration.
     
  • CAVITY : If the cavity in a tooth is so big that the retention of the tooth to hold the filling is compromised, then it becomes mandatory for the tooth to be capped/crowned with ceramic or porcelain dental crowns so that it gets reinforced and can last in the mouth and serve for a long time. For teeth that are badly damaged, ceramic and porcelain dental crowns can be an effective treatment option.
     
  • MISSING TOOTH : A bridge or a fixed partial denture is fabricated for restoring a missing tooth or an extracted tooth, where support of teeth adjacent to the missing tooth/teeth is taken and a fixed replacement is given. There are different types of bridges, depending on how they are fabricated and the way they anchor to the adjacent teeth. The materials used for the bridges include gold, porcelain fused to metal, or in the correct situation porcelain alone, Zirconium crowns When one tooth is missing in the mouth, it is mandatory to replace it. This is because if not replaced: 
  1.       The chewing efficiency gets compromised and the stomach is strained or stressed to aid in food digestion.       
  2.       Teeth move /migrate wherever they get space. If one tooth is missing the adjacent teeth move (from either side ) to occupy that            space.Also the opposing tooth (i.e. in the opposite arch) tends to move into this space. As result of movement of these teeth, fresh spaces are  created in between these teeth. These spaces are catch areas for food and can further aggravate into acute dental problems.           
  3.       One of the most common and dependable way of replacing missing tooth/teeth is a bridge where support of teeth adjacent to the missing       tooth/teeth is taken and a fixed replacement is given. So porcelain or ceramic dental caps/crowns are put on adjacent teeth to anchor the       artificial teeth which fill the gaps.

1 Metal Dental Braces    
    Metal braces are made of stainless steel and are one of the oldest types of braces. This type
of braces is relatively inexpensive compared to some of the more advanced braces.
This type of braces does have aesthetic problems as they are visible when worn and have
been known to stain teeth.

Care and Maintenance of Braces

 

1   Frequency of Cleaning    If you wear braces it is important to clean them after every meal. Food particles are
more easily trapped in the mechanisms of dental braces and can then fall through and
become lodged between the teeth. Care and maintenance of your braces will add extra
time to your at home dental care regime, but it is imperative that the task is carried out
at least twice a day, however, we recommend cleaning after every meal.
2   Flossing and Brushing for
Dental Braces
 
Flossing of the teeth should begin by pushing the floss through the arch wire and gently
moving the floss back and forward on both sides of the tooth. Do not use force when
flossing close to the arch wire.
Brushing should begin with a soft orthodontic toothbrush, top to bottom on each tooth
that has a brace attached. You should then use the proxabrush to brush between the
braces and teeth. Make sure you cover all the surfaces of each tooth before moving
onto the next tooth. Continue with this procedure until all teeth have been cleaned.
Orthodontists also recommend the use of a fluoride mouthwash that will help rinse
away any extra debris that is left in the mouth after brushing, and will help prevent
cavities.
3   Cleaning of Retainers  
If you wear a retainer it is important that this is cleaned whenever you clean your teeth. Brush the retainer clear of food at least twice per day. Also soak the retainer in a denture cleaning solution at least once per week.
4   Foods to Avoid  
The wires used in braces are not too fragile but eating hard foods such as toffees, apples or nuts, should be avoided. Hard foods can bend or break the wires, and a dental visit will need to be scheduled in order adjust the braces. Also avoid sugary snacks as this will only increase the risk of tooth decay. You can still eat this type of food but it is better to cut the food into small pieces. There will be less chance of the food getting stuck or damaging the braces, and it will also make the braces easier to clean.
5   Broken or Loose Braces  
Over time, brackets and wires may become loose; if this does happen you may be able to resolve the problem yourself. Your orthodontist should have provided you with orthodontic wax, and this can be used to slip brackets and wires back into place. If rubber bands become loose, or wires are broken, then a visit to the orthodontist will be needed to either adjust or replace these.
 

A REMOVABLE BRACE :
This is sometimes used for correcting a simple problem, such as moving a single tooth or expanding the dental arch.
It has a plastic plate with wires and usually springs attached. Removable braces need to be worn all the time except for cleaning or
for sports.
FUNCTIONAL APPLIANCES :
These are used to harness the growth of the jaws and improve the way upper and lower teeth meet. There are several designs all of
which fit on to both the upper and lower teeth and hold the lower jaw forward.

They are mostly removable but should be worn as near to full-time as possible. These are usually worn during childhood and early adolescence.
Retainers :
At the end of treatment, all patients should wear retainers to hold their teeth in the new position. These can be removable or fixed and
are an important part of treatment.
By not wearing a retainer it is possible for a relapse to occur with the teeth moving out of position.
