Accuracy of Surgical Guide in Computer Guided Implantology Clinical Trial
Official title:
Assessment of the Accuracy of Surgical Guide Designed From Dental Model Optical Scan Versus Impression Inversion With Markers Techniques in Computer Guided Implantology. Randomized Clinical Trial.
Dental model cast accuracy can be affected by many variables as tray material, impression
material and time elapsed before pouring the impression. All these factors would affect the
accuracy of the surgical guide
Impression inversion with markers technique avoids the dimension changes that may happen from
pouring of the dental model cast. Also it saves time as no need for optical scan of the model
cast and for scan appliance even in cases of multiple restoration. Adding markers to
impression tray ensures an accurate merge even if the patient has restored dentition that may
cause scatter during the CT/CBCT scan.
This study will is for Assessment of the Accuracy of Surgical Guide designed from Dental
Model Optical Scan versus Impression Inversion with Markers techniques in Computer Guided
Implantology.
