Methodologies for Assessing the Dimensional Accuracy of Computer-Guided Static Implant Surgery in Clinical Settings:...

Area of Science:

• Dentistry
• Surgical Technology
• Medical Imaging

Background:

• Computer-guided static implant surgery (CGSIS) enhances dental implant placement precision.
• Variability in accuracy reporting hinders evidence-based clinical decisions.
• Lack of standardized assessment methodologies is a key issue.

Purpose of the Study:

• To systematically map, synthesize, and analyze clinical methodologies for quantifying CGSIS dimensional accuracy.
• To identify and evaluate the diverse approaches used in assessing implant surgery precision.

Main Methods:

• Scoping review adhering to PRISMA-ScR guidelines.
• Systematic search of PubMed/MEDLINE, Scopus, and Embase up to October 2025.
• Inclusion of clinical studies comparing planned vs. achieved implant positions in humans.

Main Results:

• Extensive methodological heterogeneity observed in 21 included studies.
• Predominant reference systems: post-operative CBCT (n=12) and intraoral scanning with scan bodies (n=6).
• Inconsistent reporting of accuracy metrics (e.g., global coronal/apical deviation, angular deviation) due to varied software, algorithms, and statistical summaries.

Conclusions:

• Non-standardized measurement approaches significantly limit the comparability and synthesis of CGSIS accuracy evidence.
• Reported deviation ranges reflect methodological heterogeneity, not system performance differences.
• An urgent need exists for consensus-based minimum reporting standards in CGSIS clinical research.
