Summary

This study introduces a new surgical protocol using cylindric osteotomes for tapered implants in type 4 bone. This technique enhances primary stability, enabling predictable immediate loading even in challenging bone types.

Area of Science:

  • Dental Implantology
  • Oral Surgery
  • Biomaterials Science

Background:

  • Immediate implant placement is common after tooth extraction.
  • Achieving primary stability in type 4 bone is challenging.
  • Tapered implants are often used for immediate placement.

Observation:

  • A novel surgical protocol was developed for placing tapered implants in type 4 bone with wide ridges (> or = 8 mm).
  • The protocol exclusively uses cylindric osteotomes for alveolus preparation, avoiding conic osteotomes or drills.
  • The final cylindric osteotome size matches the conventional twist drill diameter.

Findings:

  • This technique optimizes bone compaction in the coronal third of the implant.
  • Improved bone density and enhanced primary stability values (> or = 70 ISO) were achieved.

  • The self-tapping property and anatomic design of the tapered implant contribute to stability.

    • Implications:

    • The developed technique facilitates predictable immediate loading, even in type 4 bone.
    • This method is particularly beneficial for maxillary tuberosity areas.
    • Enhanced primary stability supports long-term implant success in compromised bone.
