Guided tissue regeneration

Using bone-inducing and bone-replacement preparations (BioOss, BioGide, BioGen, BioCollagen), it is possible to carry out operations enabling reconstruction of atrophied tooth-supporting structures – reconstruction of bones destroyed by periodontal disease, reconstruction of bones before implant treatment, reconstruction of soft tissues surrounding the tooth.

When do we use guided bone regeneration (GBR)?

  1. Periodontopathy - This damage is caused by bacteria existing in the plaque. Its aggregates cause damage of supporting tissues; the tissue supporting the tooth disappears, and the ligament with its surrounding bone are destroyed, resulting in tooth loss.
  2. Apex changes - This effect is caused by inflammation around the tip of the root. Such inflammation causes destruction of bone structure.
  3. Extractions - Empty tooth socket after tooth extraction must be filled with bone-inducing granulate to avoid atrophy of the alveolus.
  4. Implant treatment
    • when the amount of patient's own bone is insufficient for the introduction of an implant
    • when the insufficient bone amount does not cover;
    • the visible thread of the implant;
    • when the alveolus is too narrow;
    • when the height of the alveolus is to small.
  5. Augmentation - Bone-inducing particles are placed in the bone loss.
  6. Covering with membrane - Holds the preparation in place and allows for proper bone reconstruction.
  7. Sinus floor elevation - Also called sinus-lifting – thickening of the bottom wall of the sinus, where the implant is to be placed (in the side part of the maxilla).  

GTR – Guided Tissue Regeneration

In case of missing teeth, an atrophy of surrounding tissues (gingiva and tooth-surrounding bone) occurs. The more time has elapsed since the tooth was lost, the larger the atrophy. Therefore, when replacing the missing tooth with an implant we must also rebuild the tissues which surrounded it in the past. Particular stages of treatment may last from 3 to 12 months, depending on the degree of gingival recession. We use bone replacement preparations, membranes and sometimes gingival transplants. The whole process is called soft tissue management.
