Bone augmentation to strengthen your jaw

Give your dental implants and prostheses a strong foundation

Bone augmentationDental implants promote your dazzling smile: These artificial tooth roots are perfect for ensuring that your dental replacements are securely attached. Sometime it is necessary to build up the bone structure of your jawbone before placement of the implant in order to ensure that it can be securely anchored. The smilin’’ dental practice in Rheinfelden has the same extensive experience in bone augmentation procedures as with implants in general. On this page we have summarised all you need to know about bone augmentation.

Dental implants and bone augmentation

As a means of attaching dental replacements such as bridges, prostheses or artificial crowns, dental implants are unquestionably the best solution. For an implant to be comfortably inserted and fuse firmly with the jawbone, the bone needs to have a minimum thickness at the envisaged implantation site. This refers both to the bone mineral density of the jaw and the thickness of the remaining layer of bone. There are various different conclusive examination methods for measuring bone density prior to a jaw augmentation treatment. One valuable tool in this context is our digital radiography system, which operates with very low radiation doses.

As a rule of thumb, there must be enough bone substance to ensure that the implant can have a length of no less than 8 to 10 millimetres. If this is not the case, a bone augmentation treatment will generally need to be performed.

Causes of bone deterioration

Bone deterioration, which may require bone augmentation in the jaw, can have several different causes:

  • After the loss of a tooth, the jawbone automatically begins to deteriorate because of the missing chewing pressures at the site.
  • Permanent friction from a dental prosthesis may accelerate the natural bone deterioration process.
  • The inflammatory gum disease periodontitis also weakens the jawbone as the disease progresses.

In the period following the loss of a tooth, bone degeneration occurs quite swiftly: In the first year, the bone recedes by 0.5 to 1 millimetre, depending on the area of jaw, and subsequently by 0.1 to 0.4 millimetres a year. If this process continues over many years or even decades, the bone layer can eventually erode until it is virtually paper thin. This is why bone augmentation should be initiated at an early stage to prevent this degenerative process in the first place.

Bone augmentation procedures

There are a variety of different options for jawbone augmentation:

Lower jaw

In the lower jaw, bone augmentation is quite often inevitable. As the pressure exerted by a dental prosthesis is generally stronger in the lower jaw than in the upper one, bone deterioration normally also progresses faster in the lower jaw. At the site accommodating the implant, a special bone substitute material is grafted into the jaw. This material will gradually fuse with the jawbone. In most cases, the required bone thickness can be achieved successfully with this procedure.

Upper jaw

Dental implant placement in the upper row of teeth very frequently requires bone augmentation. For anatomical reasons, the bone layer in the upper jaw is naturally thinner. In this area, bone augmentation can be performed with what is known as a sinus lift graft. In this procedure, the supplementary bone substance is grafted under the sinus membrane of the roof of the upper jaw (technical term: floor of the sinus).

Long-lasting solution

Bone augmentation in the jaw can have several advantages all at once:

  • Jawbone augmentation improves the stability of dental implants, generally ensuring excellent chewing functionality.
  • In conjunction with precision-tailored dental replacements made in our own dental laboratory, extremely high-quality aesthetic solutions are possible.
  • Jawbone augmentation prevents the unsightly caving in of the area around the mouth.
  • The dental implant as an artificial tooth root can help preserve the augmented jawbone over a long period of time.
