Dental Implants

Dental Implants
Dental implants are used for replacing missing teeth. Implants are more durable and longer lasting than bridges or partial dentures because they replace both the tooth and the root. A dental implant consists of the implant that is inserted in the jawbone, an abutment, and a porcelain crown. 
 
Benefits:
  • Implants restore proper chewing function and so you can enjoy foods previously too "difficult" to eat.
  • You regain the closest thing to the look, feel and function of your natural teeth
  • You can clean and floss normally
  • No fear of caries & sensitivity of teeth No more irritated and painful gums
  • Prevent the shrinking of bone and gums
  • You feel confident that your replacement teeth won’t move or loosen when eating or speaking
  • Last the longest of all the options available for replacing teeth
  • Cutting of natural teeth is avoided

You are a good candidate if you have good oral health, are generally healthy, have enough bone and you do not smoke (since smoking increases implant rejection and slows the healing process) 

Before placing an implant, it is important that your dentist has done the proper planning required with the final restoration in mind. We make use of a 3D cone beam scan to evaluate the quality and availability of bone to ensure ideal placement of the implant. This enable us to place a quality restoration . Read more about Cone beam technology in our brochure.

 

Uses:

REPLACE A SINGLE TOOTH

REPLACE MULTIPLE TEETH

PROVIDE RETENTION FOR DENTURES

Root Canal Treatment

Root Canal Treatment

Endodontic care is necessary when the nerve tissue in the tooth is irreversibly damaged due to decay, trauma, or tooth fracture. A root canal, though scary-sounding, is generally a simple pain-free procedure that allows you to retain a tooth that in previous decades would have been removed.

When the nerve inside the tooth is damaged it can be very painful and as the decay continues to spread, the nerve will die. At that point, the pain will disappear temporarily, but as the area of infection increases, an abscess forms and pressure builds. It is usually characterized by a throbbing pain and the tooth is extremely tap-sensitive. Once the damaged tissue is removed and the canal sealed with a special cement and root canal filling, the tooth can be restored with a permanent filling or crown.

Crown & Bridge Work

Crown & Bridge Work
If you have a tooth that is too damaged to be repaired with a filling, a crown can be a good way to restore it and prolong its life. Dental crowns are custom-made to fit over your existing tooth stub (after all decay and damage is removed). It will give the tooth new surfaces on all sides and be shaped precisely so as to meet the opposing teeth comfortably without affecting your bite.
 
Types of Porcelain Crowns
  • Cerec CAD/CAM technology makes it possible to make crowns, veneers, inlays and onlays in a single visit. Once the tooth is prepared, it is scanned and then the dentist will use 3D software to design the crown or restoration  after which it is milled from a solid porcelain block. It has no ugly metal lining and gains its strength by being bonded to the existing tooth structure. Cerec technology is available in Summerstrand and Uitenhage.

 

      

 

 

  •  A PFM crown has a gray metal lining to increase the porcelain strength to compensate for the weaker cementation method. Initially a new crown’s lining is slightly below the gum line, but as we age or due to inflammation or trauma, our gums may slowly recede and expose this dark edge.
  • More recently Zirconia has been developed as a lining for the porcelain. It is a white metal substance. It may also be exposed by receding gums, but being white, it is not as unsightly. The crown on the right is an example of this.
Porcelain Veneers
Veneers are ultra-thin sheets of ceramic that are bonded directly to the front surfaces of teeth. They require very conservative and minimal invasive preparations. Porcelain veneers have become increasingly popular due to their simplicity and versatility and are also highly resistant to coffee, tea or even cigarette stains.
 

Veneers can correct the appearance of:

  • Chips and cracks
  • Broken or misshapen teeth
  • Small gaps
  • Crooked teeth
  • Discoloration
Dental Bridges

When you have one or more missing teeth, one of the fixed options for filling the gap is a bridge. The teeth next to the gap are preparedfor crowns, an impression is taken and a lab technician will then fabricate a bridge that will be cemented onto the prepared teeth. The bridge will look like three crowns fused together. If the neighbouring teeth are badly decayed or heavily filled, it may be good option, but cutting healthy teeth might seem a little too invasive for many and this is where dental implants become the treatment of choice.

Dentures

Full Dentures

When you have lost all your teeth, a full set of upper and lower dentures can be made to replace the missing teeth. This will restore some function and aesthetics, but with certain limitations. Usually the upper denture fits best because it creates a sucking action against the palate whereas the lower denture lacks retention and moves around more. Dentures should be evaluated at least every 3-5 years to check the fit, bite and tooth surfaces. Worn down denture teeth will cause the jaws to close more and can lead to jaw joint problems.

Thanks to technology, you can now choose to have your dentures fixed by placing dental implants in your jaws. The implants will be fitted with a metal bar and or locator abutments. Your dentures will be modified to clip onto the abutments providing you with retention and stability. For many, this is life-changing and probably the best investment you can make considering the health benefits and improved confidence.These dentures are called implant-supported overdentures.

 
 
 
 
 
 
 
 
Partial dentures
Partial dentures can replace one or more missing teeth and we have have been the removable and economical option of choice for decades.
 
Cast Metal Partial Denture
The cast metal partial denture is the most expensive one, but also the strongest. It is less bulky, smooth and offers the best fit. This type of denture is fabricated using a metal framework with denture teeth attached to it. It usually requires two to three weeks to deliver since the metal frame is made by a specialist laboratory. 
 
Acrylic Partial Denture

Acrylic partial dentures are more affordable, but they are more bulky to compensate for the lack of strength. They have an acrylic base with denture teeth attached to it.

 
Flexi Dentures

A new innovation allows certain laboratories to make flexible partial dentures that are thinner and a lot more comfortable than conventional acrylic dentures. It has a better fit and pink flexible clasps hug the existing teeth closely, making the need for unsightly metal clasps unnecessary. 

Fillings, Inlays & Onlays

 

We are proud to announce that we promote metal-free dentistry for a number of reasons: 

  • Not only do metal restorations look ugly, turning teeth dark and gray, they also expand and contract with temperature changes. This can weaken and eventually fracture or break the teeth they were meant to protect
  • Amalgam fillings also contain mercury.  Mercury toxicity can lead to a number of serious, long-term health problems, including neurological damage, birth defects and an overgrowth of Candida in your gut.  This overgrowth of Candida may explain IBS, intolerances to gluten, etc. 

Still under debate is the issue of whether these fillings give off enough mercury vapour to threaten your body, but most people prefer not to take the risk. Whenever a silver filling is removed, a rubber dam should be used to prevent swallowing of the metal pieces.

 

 

 

 

For a small cavity, the use of tooth-coloured composite resin material is ideal.  For larger cavities, tooth fractures and replacing deep amalgam fillings, porcelain inlays and onlays should be considered.  Inlays are placed inside the tooth and onlays fill the inside of the tooth as well as cover the top or side of the tooth.  Porcelain fillings are more expensive, but they’re also the best. They resemble natural tooth structure and its characteristics  the closest. They’re tooth coloured, exert no pressure on the remaining tooth structure and preserve the remaining tooth structure the best.
