Different registration methods in dynamic computer-assisted implant surgery (d-CAIS) minimally impact accuracy. The XM registration method showed the lowest angular deviation, suggesting system-specific factors influence precision in dental implant placement.

Area of Science:

  • Dentistry
  • Surgical Technology
  • Biomedical Engineering

Background:

  • Accurate dental implant placement is crucial for long-term success.
  • Dynamic Computer-Assisted Implant Surgery (d-CAIS) enhances precision with real-time feedback.
  • Limited comparative data exists on d-CAIS registration methods' accuracy and efficiency.

Purpose of the Study:

  • To evaluate the influence of different registration methods in d-CAIS systems on implant placement accuracy.
  • To assess the impact of these registration methods on procedural time.

Main Methods:

  • A laboratory study involving three registration methods (ND, XC, XM) was conducted.
  • Five experienced operators placed 75 implants in partially edentulous maxillary models.
  • Postoperative CBCT scans measured deviations (entry point, apex, depth, angle); statistical analysis used ANOVA and Tukey's HSD test.

Real-Time Dynamic Navigation System for the Precise Quad-Zygomatic Implant Placement in a Patient with a Severely Atrophic Maxilla

Published on: October 18, 2021

Main Results:

  • Mean 3D entry point deviations: ND (1.06mm), XC (0.71mm), XM (0.90mm).
  • Mean 3D apex deviations: ND (1.23mm), XC (0.83mm), XM (1.07mm).
  • Angular deviation was significantly lower in the XM group (1.02°) compared to ND (2.96°). Procedural time was shortest in the XM group.

Conclusions:

  • Registration methods have a minimal effect on overall implant placement accuracy.
  • System-specific factors may influence angular deviation in d-CAIS.
  • Future research should focus on clinical trials and operator learning curves.
