Regeneration and guided tissue regeneration (GTR) of periodontal tissues
Regeneration of the periodontium is the ultimate goal for any patient who has lost periodontal tissues due to periodontitis. Unfortunately, even today, the applied regenerative techniques refer to specific lesions of the periodontium, such as most infrabony lesions and class II furcation involvement in mandibular molars. In addition, in heavy smokers and patients with poor oral hygiene the results are worse. Regeneration of the periodontium improves the prognosis and longevity of the teeth to which it is applied.
Radiographic imaging of a case before and after application of a guided tissue technique (collagen membrane and bone allograft). Radiographic filling of the lesion is observed and remains, after 6 months.
Application of mineralized allograft to an extensive infrabony defect. Note that an absorbable collagen membrane was placed over the graft prior to wound suture (not depicted in the photographs).
