Techniques in Complete Denture Technology

Techniques in Complete Denture Technology focus on the various methods and procedures used to create and fit complete dentures for patients who have lost all of their natural teeth. Here are some key points about these techniques: 1. Impression Technique: The first step in complete denture fabrication involves taking accurate impressions of the patient's oral tissues. This is usually done using alginate or silicone-based impression materials. The impressions are used to create stone models of the patient's mouth, which serve as a basis for constructing the dentures. 2. Jaw Relationship Recording: After the impressions are taken, the dentist needs to record the relationship between the upper and lower jaws. This helps in determining the proper occlusion (bite) and the position of the denture teeth. Various methods can be used for this, including interocclusal records, facebow transfers, and centric relation records. 3. Denture Base Fabrication: The denture base is the part of the denture that supports the artificial teeth and rests on the patient's oral tissues. It is usually made from a heat-cured acrylic resin material. The fabrication process involves pouring the gypsum casts of the patient's mouth with acrylic resin and then carefully sculpting and polishing it to achieve a comfortable fit. 4. Denture Teeth Selection and Arrangement: Choosing the appropriate size, shape, and color of denture teeth is crucial for achieving a natural-looking smile. Denture teeth are typically made from acrylic resin or porcelain. Dentists use various techniques to arrange the teeth in a way that ensures proper esthetics, phonetics, and function. 5. Denture Try-In: Once the denture base and teeth are fabricated, a try-in appointment is scheduled to evaluate the fit and appearance of the denture. This allows the dentist to make any necessary adjustments before the final denture is processed. 6. Denture Processing: After the try-in, the denture is sent to the dental laboratory for final processing. This involves packing the denture base with heat-cured acrylic resin and placing it in a specialized flask for polymerization. Once processed, the denture is finished and polished to achieve a smooth and comfortable surface. 7. Denture Delivery and Aftercare: The final step is delivering the denture to the patient and providing instructions on how to care for and maintain it. This includes proper cleaning techniques, denture adhesive usage (if necessary), and regular dental check-ups to ensure the denture's fit and function. These are just some of the key techniques involved in complete denture technology. It's important to note that the specific techniques used may vary depending on the dentist's preference, the patient's individual needs, and advancements in dental technology.
