Answer :
Final answer:
The fabrication of complete dentures entails a rigorous sequence of clinical procedures and lab steps, from taking initial impressions to the final adjustment and patient education for maintenance.
Explanation:
The clinical procedures and lab steps for the fabrication of complete dentures are a series of precise and technical stages that ensure the final dental prosthesis fits and functions properly for the patient. Although simplifying the extensive list of required steps for this process, the essential sequence of actions often includes:
- Initial dental impressions of the patient's oral structure.
- Creation of preliminary casts from these impressions.
- Detailed secondary impressions using custom trays.
- Fabrication of final working casts.
- Recording the maxillomandibular relationships.
- Establishment of occlusal plane and vertical dimension of occlusion.
- Teeth selection based on size, shape, and color.
- Setting up the teeth in wax to simulate the final denture.
- Review and adjustments during the wax try-in stage with the patient.
- Flasking the wax setup into a mold for acrylic processing.
- Pressing or injecting the heat-cured acrylic resin into the mold.
- Finishing and polishing the complete dentures.
- Final fitting and adjustment of the dentures in the patient's mouth.
- Patient education on denture care and maintenance.
Each of these steps is critical in achieving a functional and aesthetic outcome that restores the patient's oral functions and appearance.
