Accuracy of Implant Placement with Computer-Guided Surgery: A Systematic Review and Meta-Analysis Comparing Cadaver,...

Area of Science:

• Dental Implantology
• Surgical Navigation
• Medical Device Accuracy

Background:

• Computer-guided surgery (CGS) is increasingly used for dental implant placement.
• Accurate virtual treatment planning is crucial for successful implant outcomes.
• Understanding the factors influencing CGS accuracy is essential for clinical practice.

Purpose of the Study:

• To systematically review and analyze the accuracy of dental implant placement using computer-guided surgery.
• To compare virtual treatment planning and outcomes across different study types (in vitro, clinical, cadaver).
• To compare the accuracy of half-guided versus full-guided implant surgery.

Main Methods:

• A comprehensive PubMed search was conducted for studies from January 2005 to February 2015.
• Keywords included "reliability AND dental implant planning" and "accuracy dental implant planning."
• Analysis focused on horizontal coronal deviation, horizontal apical deviation, angular deviation, and vertical deviation.

Main Results:

• 34 studies involving 3,033 implants were analyzed.
• In vitro studies showed significantly less horizontal apical and angular deviation compared to clinical and cadaver studies.
• Full-guided surgery demonstrated significantly greater accuracy than half-guided surgery across various deviation metrics.

Conclusions:

• Implant placement accuracy with computer-guided surgery is reduced in clinical and cadaver settings compared to in vitro settings.
• Full-guided implant surgery offers enhanced accuracy over half-guided approaches.
• These findings highlight the importance of study type and guidance level in assessing CGS accuracy.
