Brief Summary

Return to normal life and shortening rehabilitation period of patients after surgical removal of teeth is important and urgent social problem. In this regard, higher demands for quality of care and treatment of patients, which requires the development of new approaches to the treatment of patients, the introduction of new technologies and the associated development of new materials . Serious problem of contemporary oral and maxillo-facial surgery and dentistry is augmentation of bone defects generated during the surgical treatment of diseases and injuries of the bones. The results of surgical repair of bone defects are more dependent on the course of the process of reparative osteogenesis. Long-term periods of clinical studies indicate that reparative osteogenesis in posttraumatic bone defects is slow - months and years, and in some cases no bone defects filled with bone tissue. This project aims at addressing the preservation of bone volume in humans after tooth extraction using biomaterials with optimum performance. The practical significance of the project is to establish an effective tissue response and, thus, possible subsequent quality installation of dental implants. The proposed solution is based on the scientific development of the operative techniques, and a comparative analysis of several classes of biomaterials (xenogenic and synthetic analogs), including the use of biological precursors of bone apatite mineralization having osteoinductive (stimulating) properties.

Outcome Measures

Primary Outcomes (1)

  • The changes of bone level between baseline and 3 months post-extraction at the time of implantation

    A prefabricated stent will be used as an anchor point. After tooth extraction size of dehiscence of buccal bone from anchor point to the alveolar crest will be measured (baseline). Socket will be filled with biomaterial. After 3 months of healing at the time of implant placement the same stent will be used as an anchor point to measure size of dehiscence after socket preservation.

    baseline and 3 months post-extraction

Secondary Outcomes (1)

  • Percent new vital bone formation

    3 month

Other Outcomes (1)

  • Percent residual graft material and percent connective tissue

    3 month

You may not qualify if:

  • Patient who has any known diseases (not including controlled diabetes mellitus), infections or recent surgical procedures within 30 days of study initiation
  • Female patient who are pregnant or lactating or of child bearing potential not using acceptable methods of birth control (hormonal, barriers or abstinence
  • Patient who are on chronic treatment (i.e., two weeks or more) with any medication known to affect oral status (e.g., phenytoin, dihydropyridine calcium antagonists, cyclosporine, and non-steroidal anti-inflammatory drugs) within one month of baseline visit
  • Patient who knowingly has HIV or Hepatitis
  • Alcoholism or chronically drug abuse causing systemic compromisation
  • Patient who is a heavy smoker (\>10/cigarettes per day).
  • Uncontrolled or untreated periodontal disease
  • Patient who has a full mouth plaque level \>30 % at the enrolment visit
  • History of local radiation therapy
  • Presence of oral lesions (such as ulceration, malignancy)
  • Persistent intraoral infection
  • Patients presenting clinical and radiological signs and symptoms of maxillary sinus disease
  • Patient presents an acute endodontic lesion in the test tooth or in the neighbouring areas to the experimental procedure (sites with presence of an asymptomatic chronic lesion are eligible)
