Comprehensive Clinical Evaluation and Diagnosis A full clinical and radiographic examination must be conducted to assess the condition of the remaining teeth, supporting tissues, and overall oral health. ✔ Goal: Evaluate occlusion, abutment integrity, periodontal status, and hygiene before prosthetic planning. 2. Preliminary Design and Diagnostic Cast Analysis Diagnostic casts are mounted in a semi-adjustable articulator. The initial design includes selection of: ✔ Major connector, direct retainers, guiding planes, occlusal rests, and indirect retainers. 3. Pre-Prosthetic Mouth Preparation All required intraoral adjustments are made before impressions: ✔ Guide plane preparation, crown placement or modification, extractions, and periodontal therapy. 4. Final Impression with High-Precision Material A custom tray and elastomeric impression material (e.g., polyether or addition silicone) are used. ✔ Accurate capture of both hard and soft tissues is crucial. 5. Master Cast and Refractory Model Duplication A master cast is created from the impression, and a refractory duplicate is prepared for framework fabrication. ✔ Final design details are transferred to the laboratory via design sketches and written instructions. 6. Metal Framework Casting The dental technician waxes the framework, invests it, and casts it using a cobalt-chromium alloy. ✔ A passive fit of the framework is then verified intraorally. 7. Maxillomandibular Relationship Records If necessary, jaw relation records are obtained for mounting the cast in the articulator. 8. Tooth Setup and Esthetic Try-In Artificial teeth (usually acrylic) are selected and set in wax for esthetic, phonetic, and occlusal evaluation. 9. Final Processing and Polishing The denture is processed with heat-polymerized acrylic resin and polished for delivery. ✔ Final prosthetic adjustments are performed before delivery. 10. Delivery, Patient Instructions, and Follow-Up ✔ The denture is delivered and adjusted. The patient is instructed on hygiene, use, and maintenance. ✔ Follow-up is scheduled at 24–48 hours, one month, and semiannually.
