Clinical Trial Summary

The study will compare the accuracy of surgical guides fabricated by two different scanning protocols; facially driven scanning versus dual scanning protocol regarding the deviation of implant placement.


Description:

Twelve completely edentulous patients will be selected for full arch maxillary guided implants placement with immediately loaded restoration. The patients will make a complete oral and radiographic examination before inclusion in this study. All patients will receive maxillary and mandibular complete dentures that will be made in a conventional way. The patients will be randomly divided into two equal groups; group (I) and group (II). In both groups two CBCT scans will be made. A CBCT scan will be made for each patient while wearing the radiographic stent and another CBCT scan will be made for the radiographic stent alone. However, for patients in group II a face scan will be added to previous scans. For each patient in group I, the DICOM files will be exported to Blue Sky implant designing software (Langenhagener, Mdi Europa GmbH), fusion of the scan prosthesis via the markers is accomplished and the ideal surgical site and optimal implant dimensions will be selected. All the surgical guides will be planned to be totally limiting in this study. The immediate provisional restoration will be planned on the software according to the previously planned implants sites. The surgical guide will be 3D printed. The approved tooth arrangement will be subsequently sent as an STL file to a milling machine. For each patient in group II, the DICOM files and the STL files obtained from the face scans will be exported to Blue Sky implant designing software (Langenhagener, Mdi Europa GmbH). The facial scan will be used to define the interpupillary and midsagittal planes and to examine the tooth form and buccal corridor width with regard to the patient's smile line. Both files data will be superimposed and the planning for the implants sites, surgical guide and immediate restoration will be done as in group I. After implant insertion, CBCT scan will be made for each patient while wearing the scan appliance. Superimposition of CBCT scans pre and post implant insertion and restoration will be made. Deviations between planned and placed implant will be measured in the lateral apical, lateral coronal and angular aspects. Also, the patient satisfaction will be measured on a likert scale.

Outcome

Type Measure Description Time frame Safety issue
Primary ( Assessment of linear deviation Accurate details recorded by superimposition of CBCTs using the blue sky software program by measuring the lateral coronal deviation in millimeters. 1day
Primary ( Assessment of linear deviation Accurate details recorded by superimposition of CBCTs using the blue sky software program by measuring the lateral apical deviation in millimeter. 1day
Primary ( Assessment of angular deviation Accurate details recorded by superimposition of CBCTs using the blue sky software program by measuring the angular deviation in degrees. 1day
Secondary patient satisfaction Accurate details recorded by using a 5 points likert scale for measuring the patient satisfaction by filling specific questionnaire: Oral Health Impact Profile 14 questions ( OHIP-14) and taking the answer of each question on a 5 point likert scale with 0 for the worst score and 5 for the best one 1 day
