The correct sequence for fabricating complete dentures involves A) clinical procedures: Preliminary impressions, Final impressions, Jaw relation records, Try-in appointments; followed by lab steps: Primary cast fabrication, Custom tray fabrication, Master cast fabrication, Baseplate and wax rim fabrication, Teeth setup, Processing, Finishing and polishing. This sequence is pivotal for ensuring a precise and comfortable fit.

Explanation:

The correct sequence for the clinical procedures and lab steps in the fabrication of complete dentures involves a methodical process where each step builds upon the previous one to ensure a precise and comfortable fit for the patient. The correct sequence is:

Preliminary impressions
Final impressions
Jaw relation records
Try-in appointments

Followed by the lab steps:

Primary cast fabrication
Custom tray fabrication
Master cast fabrication
Baseplate and wax rim fabrication
Teeth setup
Processing
Finishing and polishing

This sequence ensures that the dentures are accurately tailored to the patient's individual oral anatomy, leading to a better fit and greater comfort.
