This study introduces a novel screw system for precise dental implant placement. These fixed intraoral reference points ensure accurate template positioning, improving surgical outcomes in complex cases.

Area of Science:

  • Dental implantology
  • Surgical template technology
  • 3D treatment planning

Background:

  • Current 3D planning software aids implant placement but often lacks template stability in edentulous patients.
  • Existing systems struggle with reliable intraoral template fixation, impacting precision.
  • The need for stable reference points in computer-assisted implant surgery is critical.

Observation:

  • A new screw system was developed to serve as fixed intraoral reference points.
  • This system enhances the stability and support of diagnostic and surgical templates.
  • The application of this screw system was evaluated in conjunction with computer-assisted 3D implant placement.

Findings:

  • Implants were precisely placed according to the 3D treatment plan.

  • The screw system facilitated exact transfer of the virtual plan to the intraoral situation.
  • Accurate implant positioning was achieved even near sensitive anatomical structures like the mandibular nerve and mental foramen.

    • Implications:

    • Fixed intraoral reference points, like the described screw system, significantly improve the precision of computer-assisted implant placement.
    • This method offers an efficient way to ensure accurate template positioning, crucial for successful dental implant surgery.
    • The findings support the integration of stable reference systems for enhanced accuracy in demanding clinical scenarios.
