Comparison of Implantation Accuracy Among Different Navigated Approaches: A Systematic Review and Network
The International Journal of Oral & Maxillofacial Implants
|November 1, 2023
Summary
This study found that guided dental implant placement methods, including dynamic navigation (DN) and fully guided static navigation (FG), are more accurate than freehand (FH) techniques. DN excels in apical and angular accuracy, while FG offers superior coronal control.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomedical Engineering
- Dental Implantology
Background:
- Dental implants are crucial for tooth loss restoration, with placement accuracy directly impacting success.
- Various implant placement modalities exist, including freehand (FH), partially guided (PG), fully guided static navigation (FG), and dynamic navigation (DN).
Purpose of the Study:
- To compare the accuracy of different dental implant placement modalities: dynamic navigation (DN), fully guided static navigation (FG), partially guided static navigation (PG), and free handed (FH) using a network meta-analysis.
- To determine which modality offers superior accuracy in terms of coronal, apical, and angular deviations.
Main Methods:
- A systematic literature search adhering to PRISMA guidelines was conducted.
- Network meta-analysis of 17 randomized controlled trials (RCTs) was performed, supplemented by qualitative analysis of 26 articles.
- Implant accuracy was assessed by measuring deviations at the crown, apex, and angular discrepancies.
Main Results:
- Fully guided static navigation (FG) and dynamic navigation (DN) demonstrated higher accuracy for coronal deviation compared to freehand (FH).
- FG, DN, and PG showed improved accuracy for apical and angular deviations versus FH.
- Surface Under the Cumulative Ranking Curves (SUCRA) indicated FG as most accurate for coronal deviation, and DN for apical and angular deviations.
Conclusions:
- Dynamic navigation (DN), fully guided static navigation (FG), and partially guided static navigation (PG) offer superior accuracy over freehand (FH) implant placement.
- DN provides the highest accuracy for apical and angular deviations, while FG excels in coronal deviation control.
- No significant accuracy difference was found between DN and FG, though further validation is recommended.

01:17Common Leveling Mistakes and Errors
A survey team is tasked with determining the elevation difference between points Point A and Point B, separated by uneven terrain. They use a leveling instrument and a leveling rod.Common MistakesMisreading the Rod: During a backsight reading at Point A, the instrumentman observes the rod partially obscured by tall grass. Instead of reading 1.135 m, they mistakenly record 1.735 m due to the misalignment of the crosshair with the wrong graduation. This error adds 0.600 m to all subsequent...
