Clinical Trial Summary

The dental implant placed freehand with a digital planing is vastly increasing. The accuracy between the planned and the placed implants still not well determined. Between a single implant and a full mouth rehabilitation, the precision is very wide. A precision scale must be settled according to each indication in order to offer the clinician a safety and a predictability for his procedures.


Description:

In this paper the investigators report an original research evaluating the accuracy of computer-guided implant placement in posterior edentulous mandibular spaces. In this randomized controlled trial, several factors were evaluated such as primary implant stability, possibility of immediate loading, displacement at crestal and apical levels, angle of deviation, surgical guide design, computer-aided design and computer-aided manufacturing accuracy, and variance between different implant macro-geometries and lengths. As exhaustive description of the assessment techniques as well as the statistic results were also presented in this article. Nowadays, the use of guided surgery is vastly increasing in a daily dental practice. In the "Era of Digital Dentistry", it is of utmost importance to evaluate the accuracy and precision of the computer-guided techniques in order to determine their limits, avoid risks (adjacent anatomical structures, limited crestal volume, immediate loading), and apply them in safe manner. Evidence-based scientific data on this matter is still deficient. In these terms, the investigators consider it very interesting and of high clinical value for all oral surgeons and dental practitioners to evaluate in a clinical research the precision and distortion of computer-guided implant surgery.

Outcome

Type Measure Description Time frame Safety issue
Primary Assess Accuracy of Implant Placement in Vertical Displacement (VD). Evaluate the accuracy of implant placement by comparing the planned positions (from the computer) with the actual positions of the placed implants (using the printed guide). The tool to assess the accuracy/deviation is a software that superimpose two "Digital Imaging and Communications in Medicine" (DCM) Files of the planned and the actual position implants. the first DCM issued from the planning software and second DCM file after scanning the implant in the jaw. The first outcome measure was provided to calculate the amount of distortion in millimeter (mm) for the Vertical Displacement (VD) (mm). 4 months
Primary Assess Accuracy of Implant Placement in Horizontal Displacement (HD) Evaluate the accuracy of implant placement by comparing the planned positions (from the computer) with the actual positions of the placed implants (using the printed guide). The tool to assess the accuracy/deviation is a software that superimpose two "Digital Imaging and Communications in Medicine" (DCM) Files of the planned and the actual position implants. the first DCM issued from the planning software and second DCM file after scanning the implant in the jaw. The second outcome measure was provided to calculate the amount of distortion in millimeter (mm) for the Horizontal Displacement (HD). 4 months
Primary Assess Accuracy of Implant Placement in Error Depth (ED) Evaluate the accuracy of implant placement by comparing the planned positions (from the computer) with the actual positions of the placed implants (using the printed guide). The tool to assess the accuracy/deviation is a software that superimpose two "Digital Imaging and Communications in Medicine" (DCM) Files of the planned and the actual position implants. the first DCM issued from the planning software and second DCM file after scanning the implant in the jaw. The third outcome measure was provided to calculate the amount of distortion in millimeter (mm) for the Error Depth (ED) (mm). 4 months
Primary Assess Accuracy of Implant Placement in Error Angle (EA) Evaluate the accuracy of implant placement by comparing the planned positions (from the computer) with the actual positions of the placed implants (using the printed guide). The tool to assess the accuracy/deviation is a software that superimpose two "Digital Imaging and Communications in Medicine" (DCM) Files of the planned and the actual position implants. the first DCM issued from the planning software and second DCM file after scanning the implant in the jaw. The fourth outcome measure was provided to calculate the amount of distortion in in degree of the Error Angle (EA). 4 months
Secondary Evaluate Precision of the Printed Guide Assess how precisely the printed guide translates the planned positions to the actual implant placements. Using the same assessment tool as for the primary outcome measure. 4 months
Secondary Study Complications and Adverse Events Monitor and report any complications or adverse events associated with the use of the printed guide during implant placement. 4 months
