Brief Summary

An study will be conducted on patients whopresent to the OPD with completely edentulous maxillary and mandibular jaw.Athorough intraoral examination will be carried out.  Ingroup â… patients conventionally border molded impression with a custom tray will bemade and a definitive cast will be obtained. A record base with heat polymerizingacrylic resin will be made on the definitive cast. Ingroup â…¡patients the maxilla will be scanned using an intraoral scanner. The scannedimage will be modified by incorporating coding calculations according to theresiliency of the tissues. Using the modified scanned image, the CAD-CAM bases willbe milled.  Aplatform will be designed with a 45-degree inclination. A dislodging force willbe applied via a dynamometer connected to a hook. This will simulate thedislodging force thus, clinically testing record base retention.  Theretention offered by the conventional record base and CAD-CAM milled recordbases from the modified intraoral scan will be compared.

Primary Outcome Measures

Name	Time	Method
This study integrates the modified digital scans in the workflow of complete denture fabrication. Modified Digital impression will result in more time efficient technique than conventional impression. By the end of the study, we will know whether resiliency of tissues can be recorded by modified digital scans.	This study will be carried out for a period of 1 year.

Secondary Outcome Measures

Name	Time	Method
This study integrates the modified digital scans in the workflow of complete denture fabrication. Modified Digital impression will result in more time efficient technique than conventional impression. By the end of the study, we will know whether resiliency of tissues can be recorded by modified digital scans.	At time of jaw relation. This study will be caried out over a period of 1 year.
