NCT04719624

Brief Summary

The aim of this study is to demonstrate that new synthetic bone graft bioceramic composites (Adaptos®-Si and Adaptos®, Biomendex Oy) are able to support the preservation of the alveolar ridge and to promote bone regeneration following dental extraction. New bone graft substitutes are compared with already existing treatment principles used following dental extraction. The primary hypothesis of the study is that Adaptos®-Si granules can reach a clinical outcome superior to that of dental socket left empty after extraction. Secondary aim is that new bioceramic composites can reach a clinical outcome non inferior to the active comparator of this study (Geistlisch Bio-Oss®).

Outcome Measures

Primary Outcomes (1)

  • Alveolar ridge preservation, comparison between Adaptos-Si filled extraction sockets and empty sockets.

    Alveolar ridge horizontal and vertical change assessment by cone-beam computed tomography (CBCT). The vertical reference line is outlined from the apex through the center of the socket and the horizontal reference line through the apex perpendicular to the vertical line. The ridge width (in mm) is measured parallel to the horizontal reference line 1 mm, 3 mm, and 5 mm from the highest buccal ridge point on baseline. Ridge heights (in mm) are measured from the most apical point of the alveolar socket parallel to the vertical reference line. The dimensional changes of the ridge assessed on CBCT images immediately post-extraction, are acquired five months and ten months later. Comparison between Adaptos-Si filled extraction sockets and empty sockets.

    baseline, 5 months, and 10 months post-extraction

Secondary Outcomes (3)

  • Alveolar ridge horizontal and vertical change (in mm) assessment by CBCT, comparisons between extraction sockets filled with Adaptos-Si or Bio-Oss bone graft substitutes.

    baseline, 5 months, and 10 months post-extraction

  • Alveolar ridge horizontal and vertical change (in mm) assessment by CBCT, comparison between Adaptos filled extraction sockets and empty sockets.

    baseline, 5 months, and 10 months post-extraction

  • Alveolar ridge horizontal and vertical change (in mm) assessment by CBCT, comparison between extraction sockets filled with Adaptos-Si or Adaptos bone graft substitutes.

    baseline, 5 months, and 10 months post-extraction

Other Outcomes (1)

  • Comparison between radiological assessment methods

    baseline, 5 months, and 10 months post-extraction

Device: Adaptos® (bone grafting surgery)

Interventions

After screening and enrollment, subjects will undergo tooth extraction of a single tooth with placement of one of the four randomized, synthetic bone graft substitutes with a gelatin sponge (Spongostan Dental). Following 5 months of healing a dental implant will be placed. The subjects will then be followed for another 5 months for healing. Follow-up visits will be at 2 weeks, 5 months, and 10 months.

Also known as: Ridge preservation bone grafting after tooth extraction.
