Our teeth not only serve to chew the foods we eat, but they dramatically affect the way we look and feel about ourselves.

Teeth help to keep us healthy by allowing us to eat and chew the foods we enjoy. Teeth help us to look younger. Our teeth, gums and bone support the facial structures and keep them from sagging and caving in. Without teeth to support our facial tissues, we would appear much older.

Teeth help build our self-esteem and confidence, by giving us an attractive and youthful smile.

Investing in your teeth is an investment in your health. Aren’t you worth it?

Why Replace a Missing Tooth?

why replace a missing toothWhen lower back teeth are missing, the teeth behind the space tip inwards and forwards. The teeth on top can shift and move (extrude) into the space. Failure to replace missing teeth results in much larger problems occurring over time requiring more extensive treatment. People with crooked teeth are more susceptible to gum disease. They lose bone and tissue around the roots of the teeth. The bone in the area of the missing teeth can shrink away and over time can result in facial collapse. One’s ability to chew can be affected and chewing forces are transferred to the other teeth resulting in compromised support, increased wear and deterioration. Replacing missing teeth immediately after they are lost can provide many benefits including reduced long term costs and improved
overall health.

Consequences of Tooth Loss

cosequences of tooth lossTeeth are important in maintaining your health and supporting your facial structures. Teeth help you to chew food properly, and keep you healthy. The teeth also help to keep the jaw bone in place, which helps to support the facial muscles. Without teeth, the bone would shrink and the skin would collapse, causing premature aging.

cosequences of tooth lossWhen a tooth is missing, it should be replaced to prevent major problems that occur over time to the surrounding teeth and tissues. Missing teeth can affect the ability to chew. Forces are transferred to the other teeth resulting in compromised support, increased wear and deterioration. Bite problems can also develop with the shifting of teeth and chewing forces.

cosequences of tooth lossWhen a tooth is missing, the tooth behind the space tips forward and the tooth above the space grows down. Crooked teeth cause bite problems and are more susceptible to gum disease. The bone shrinks where the tooth is missing and over time can result in facial collapse. Replacing missing teeth can help prevent many of these consequences, and provides many long term benefits with improved health.

Complete Upper Dentures

complete upper denturesWhen all of the teeth are extracted in the upper jaw, the bones heal and are covered by gum tissue. A complete denture can be made to replace the missing teeth, which rests on the gums and is supported by the underlying bone. The complete denture is made from plastic and covers the roof of the mouth. Over a period of years, the amount of bone and the nature of gum tissue supporting the denture will deteriorate. As the gum and bone changes, there may be a need for relining or remaking of the denture.

complete upper denturesThe teeth which are attached to the plastic base of the denture come in a wide variety of shapes, sizes and colors. You and your dentist can choose the type of teeth that best suits your smile and appearance. Often a complete denture provides excellent aesthetics in replacing missing teeth, however, the chewing function of natural teeth cannot be replaced by a denture. For some individuals, depending on the amount and type of supporting tissues, there may be movement of the denture, causing sore areas on the gums and in some cases affecting speech. Most people however, can successfully wear complete dentures.

Partial Dentures-Tooth Borne

partial dentures tooth borneA partial denture is used to replace missing teeth. It is a removable prosthesis, and depends on the remaining teeth and tissues for stability and support. In situations where there is a large number of missing teeth, or where there is a lack of bone, implants or bridges may not be possible. In these cases, a partial denture may be the treatment option of choice.

partial dentures tooth borneA partial denture has a metal substructure which allows it to be thin, yet strong. Clasps are integrated into the design that attach to existing teeth. The missing teeth are replaced using plastic teeth, to closely match the color of the adjacentteeth.

partial dentures tooth borneA free end partial denture is partially supported by the existing teeth and rests on the soft tissue. Depending on the number of remaining teeth and the amount of tissue support, a free end partial denture may have some movement during function. Partial dentures can provide an aesthetic replacement for missing teeth.

Implant Supported Overdenture

  • implant supported overdenture
    This model shows 2 implants placed in the jaw bone with attachments added. A denture will be fabricated which will then fit over the implants.
  • implant supported overdenture
    From the front view, we can see the attachments which have been secured to the implants. These attachments will provide retention to reduce the amount of movement of the denture during function.
  • implant supported overdenture
    The underside of the denture shows how it is contoured to fit over the jaw bone and gum tissues, but also contains attachments which fit over the implants.
  • implant supported overdenture
    This type of denture is mostly gum supported but gains some stability through the implant attachments. The denture still has some movement, but is more stable than a conventional denture without implants.

implant supported overdentureThis lady lost all of her lower teeth and wore a complete denture for many years. Due to the shrinkage of the jawbone after losing her teeth, her lower denture became very unstable. She chose to proceed with an overdenture on 2 implants. The implants resist further deterioration and help to preserve the remaining jaw bone.

What is a Bridge?

  • what is a bridge
    This existing bridge requires replacement. There is wear on the biting surfaces and the tissue has shifted, exposing the metal around the edges of the bridge.
  • what is a bridge

    Once the old bridge is removed, the teeth are prepared for a new bridge. The outer layer of the teeth must be removed to accommodate the metal and porcelain used to fabricate the bridge.

  • what is a bridge
    The bridge is made in a laboratory using molds made of the prepared teeth. The bridge has a metal substructure over which porcelain is bonded. The color of porcelain is chosen to match the existing teeth.
  • what is a bridge
    The bridge is adjusted and fitted over the teeth. It is then cemented into place.

Bridge Procedure

  • bridge procedure
    A bridge is one of the treatment options to replace a missing tooth. A tooth is usually required on either side of the space upon which the bridge is supported. Fabrication of a bridge generally requires two appointments.
  • bridge procedure
    At the first appointment, the supporting teeth are altered for the bridge and a mold is made. A temporary plastic bridge is made at this appointment, which is cemented in place until the final bridge is ready.
  • bridge procedure
    The bridge is made by a dental technician using the mold. At the second appointment, the bridge is fitted into place. The color of the bridge, the shape and the bite are checked. This see-through image shows how the bridge fits over the supporting teeth.
  • bridge procedure
    When both you and your dentist are pleased with the fit, color, shape and bite, the bridge is cemented into place. This type of restoration generally provides an aesthetic and functional result.

Fixed Reconstruction – Implants Supported

fixed constructionWhen all the teeth have been lost, implants can be
placed to replace all the missing teeth if there is sufficient bone remaining. This model shows the positioning of 8 implants within the lower jaw, with posts attached. The implants provide enough support and stability, llowing the final restoration to be fixed into place.

fixed constructionThe picture to the right shows the final teeth which have been fabricated over the posts. These teeth have been made using a metal substructure over which porcelain has been added. This type of restoration is well supported and the positioning of the implants allows chewing forces to be properly distributed, providing a highly functional
restoration.

Fixed-Detachable Prosthesis

fixed-detachable prosthesisAfter implants are placed in the jaw a substructure is made that fits into the implants. This substructure sits on top of the implants and does not rest on the gums. It provides the base for the attachment of teeth.

 

fixed-detachable prosthesisThis top view shows the artificial teeth in place. The teeth and artificial gums are attached to the substructure creating one single unit that is then screwed into place attaching it to the implants. The screw holes are then sealed with filling material.

 

fixed-detachable prosthesisThis front view shows the teeth attached to
the implants. The dentist inserts the teeth by screwing them into the implants. The teeth do not come out and cannot be removed by you the patient. The full biting force is absorbed by the implants creating artificial teeth that are both comfortable and powerful.
