-> Sometimes complicated operations are required.

Extraction of dental units

This is probably one of the dental techniques best known by all: After administering a small dose of local anesthetic, first of all the gum is gently separated from the bad tooth. Then the tooth is loosened from the bone compartment and removed. Depending on each case, the socket in the bone closes by bleeding or a tampon impregnated with an ointment is placed into the socket.

Surgical tooth removement

This is usually done for “wisdom teeth” mal-positioned and/or covered with a thin layer of bone which prevents them from emerging.

Incision of abcesses

The typical swelling – frequently comes from an infected tooth: the inflammation of the alveolar nerve or the structures around the tooth can provoke an infection with pus which, due to being close to brain and neck tissues, can have very serious consequences and even be a vital risk. Therefore, a swelling should never be taken easily. Whenever a swelling is formed in the region of the skull, this has to be opened and pus drained. Naturally, the factor causing the infection should also be eliminated – which could include the extraction of the corresponding dental unit.

Apical resection

The anatomy of the apex can sometimes cause a root canal treatment to fail (see also Preservative Dentistry). The root canal often ends up in a delta-shape – which is practically impossible to clean. The apical resection basically consists of eliminating this part of the root canal. First a route is found to the tooth and the apex is located. Then the bone tissue covering it is removed and the apex shortened by 1 to 2 mm. This enables the critical apex zones to be eliminated and the probabilities of success of a root canal treatment to be increased. Should this be necessary, the bone defects can be filled with a material that stimulates regeneration (e.g. Bio-Oss®).

Apical resection is the last resort we have when trying to preserve a dental unit after having performed a root canal treatment. Apart from extraction, there are no other alternatives.

Surgical periodontal treatment

Carrying out a root-scaling (see also Preservatve Dentistry) could possibly not be enough in advanced cases of periodontal disease. Calcified bacterial layers on the root surface have caused deepening pockets with inflammation. The substances segregated by the inflamed cells not only attack the bacteria but also the bone and the structures supporting the tooth. It is therefore necessary to eliminate the bacterial pockets by surgical means such as flap-operation.

By making an incision in the gum, the affected areas of the root are opened. Then a root-scaling is done, afterwards a root planing. The tissues are then closed by special sutures.

In case of need, the bone defects can be filled in with a special material to stimulate regeneration (e.g. Bio-Oss®). To cover exposed roots, especially of front teeth, a connective-tissue graft can be inserted.


Tissue build-up is mainly applied to bone. When there is not enough bone, a reconstruction is done within the framework of periodontal therapy and implants. To achieve this, a graft is used from other areas of the mouth cavity or materials for augmentation(e.g. Bio-Oss®), normally covered by membranes(e.g. Gore-Tex). Defects of the jaw-ridge in the front area can also be reconstructed by using soft tissue grafts, obtaining satisfactory esthetic results.

As all these treatments are complex and very special, we would gladly give you more information you might need here in the clinic
