PICDental®: The ideal digital tool for multiple implant impression
Introduction. The objective of this study was to show the effectiveness and efficiency of photogrammetry (PICDental®) as an alternative tool to silicone impression techniques and custom open tray when achieving passive fit.
Material and methods. 22 patients with partial or total dental loss were treated with 147 implants and rehabilitated with monolithic prostheses that included a minimum number of 5 implants and up to a maximum of 8. All implants were restored. 43 implants were loaded immediately and 104 after a healing period of 3 months in the jaw or 6 months in the maxilla.
Results and Discussion. The clinical findings indicate that the passive fit achieved by PICDental® was 100% at the first attempt, while the silicones were 33%. The working time is significantly shorter (3:1) when PicDental® is used, the radiological exposure time is constant and insignificant (13.2 seconds) when the PicDental® is used. After a mean functional loading period of 36 months, there have been no late mechanical complications.
Conclusions This study indicates that PicDental® is a fast and accurate implant capture tool. Furthermore, it is especially reliable when the number of dental implants to be captured is higher than six units.
