This study shows that the biologic width around non-submerged titanium implants is stable over time, even under loading. While individual tissue components like sulcus depth and junctional epithelium change, their sum remains consistent, indicating reliable soft tissue integration in implant dentistry.

Area of Science:

  • Dental Implantology
  • Periodontology
  • Biomaterials Science

Background:

  • Soft tissue integration is crucial for dental implant success, yet less studied than hard tissue integration.
  • Understanding the peri-implant soft tissue response, specifically the implantogingival junction, is vital for long-term stability.
  • Non-submerged, one-piece titanium implants are increasingly used, necessitating data on their soft tissue interactions.

Purpose of the Study:

  • To histometrically analyze the implantogingival junction of unloaded and loaded non-submerged titanium implants.
  • To evaluate changes in Sulcus Depth (SD), Junctional Epithelium (JE), and Connective Tissue Contact (CTC) over time.
  • To determine the stability of the Biologic Width (BW) around these implants.

Main Methods:

  • 69 non-submerged titanium implants were placed in 6 foxhounds.
  • Implants were analyzed histometrically in unloaded and loaded (with gold crowns) conditions at 3, 6, and 15 months.
  • Measurements included Sulcus Depth (SD), Junctional Epithelium (JE), and Connective Tissue Contact (CTC).

    • Main Results:

    • Significant changes were observed in SD, JE, and CTC over the 15-month period (P < 0.05).
    • Despite dynamic changes in individual components, the total Biologic Width (SD + JE + CTC) remained stable (P > 0.05).
    • Loaded implants demonstrated stable peri-implant soft tissues for up to 12 months.

    Conclusions:

    • The Biologic Width is a physiologically formed and stable structure around non-submerged, one-piece titanium implants.
    • Non-submerged implants facilitate stable peri-implant soft tissues under loaded conditions.
    • Dynamic changes within the Biologic Width components do not compromise overall soft tissue stability.
