Root - the last anchor for the natural tooth
Endodontic therapy may represent an additional apicoectomy often the last chance to get a natural tooth. If the tooth is properly supplied, he is worth preserving in any case and has a good prognosis.
The Root pose for odontogenic infections, the drug of choice for infected tooth with the causative pathogen-proof channel accounts (root filling) and removal of infected ramifications (Fig. 1) at the root tip, including the chronic tissue in the root tip will receive a permanent basis.

When must be made a Wurzelspitzenresktion?
The main indications for this procedure are the periapical lesions (periapical osteitis, granuloma, cyst) and pulp necrosis after unsuccessful conservative (conservative) is the root filling (Fig. 2).
Figure 2
If not successful root filling should be filled with the aid of standardized tools for orthograde treatment in the same procedure, the root canals. Is there a ausrechende already filling the channels, it is enough for the root of severed root tip with a retrograde filling to seal. Thus, there is the apicoectomy with orthograde and retrograde filling. In any case, the infected portions of the root tip are removed and the residual lumen of the root canal with a retrograde filling sealed (Fig. 3).

The painless procedure
Most can perform the surgery under local anesthesia in no pain. After dissection of the mucous membrane that is pushed back and opened the bones in the direction of root tip with a bone cutter. The root tip is removed over a length of about 3 millimeters at an angle so that the infected branches can be eliminated (Fig. 4).

The chronically infected periapical tissue is sharply up on the healthy bone curetted out and suspicious findings on histological (histological examination). There will be a Nahtversorgung, which can be removed after one week. After the operation, it is innvoll to cool the area for about 3 days, a pain medication is prescribed.
The fact that the bone grows into the resulting cavity, the tooth, the tooth is re-established and can usually still be kept for many years. Moreover, the chronic inflammation that can be harmful to the entire organism as Herdinfektion eliminated.
