Summary

HTR polymer shows high biocompatibility in periodontal osseous defects, with minimal inflammation and good bone presence. This synthetic bone graft material is well-tolerated, indicating suitability for periodontal regeneration.

Area of Science:

  • Periodontology
  • Biomaterials Science
  • Regenerative Medicine

Background:

  • Periodontal osseous defects often require regenerative therapies.
  • Gingival tissue response to biomaterials is crucial for successful treatment outcomes.
  • HTR polymer is a synthetic material used in bone grafting.

Purpose of the Study:

  • To evaluate the gingival tissue response to HTR polymer in periodontal osseous defects.
  • To assess bone presence and osteogenesis associated with HTR polymer grafts.
  • To compare the tissue response to HTR polymer with other graft materials.

Main Methods:

  • Biopsies were obtained from eleven patients 6-7 months post-HTR polymer implantation in periodontal osseous defects.
  • Histological analysis examined inflammation, foreign body giant cells, bone presence, and osteogenesis.

  • Comparative analysis included biopsies from sites treated with other graft materials or debridement alone.

    • Main Results:

    • Minimal inflammation and infrequent foreign body giant cells were observed around HTR polymer.
    • Bone was present in approximately 50% of HTR-grafted samples.
    • Osteogenesis associated with the HTR graft material was noted in about 20% of biopsies.
    • Similar tissue responses were observed for other graft materials and debridement-only sites.

    Conclusions:

    • HTR polymer demonstrates excellent biocompatibility in periodontal osseous defects.
    • The material elicits no adverse gingival tissue responses.
    • HTR polymer is a suitable biomaterial for periodontal regeneration, comparable to other available options.
