The fabrication of a set of complete dentures is a challenge for any dentist/denturist. There are many axioms in the production of dentures that must be understood; ignorance of one axiom can lead to failure of the denture. In the vast majority of cases, complete dentures should be comfortable soon after insertion, although almost always at least two adjustment visits are necessary to remove the cause of sore spots. One of the most critical aspects of dentures is that the impression of the denture must be perfectly made and used with perfect technique to make an accurate model of the patient's edentulous (toothless) gums. The dentist or denturist must use a process called border molding to ensure that the denture flanges are properly extended. An array of problems may occur if the final impression of the denture is not made properly. It takes considerable patience and experience for a dentist to know how to make a denture, and for this reason it may be in the patient's best interest to seek a specialist, either a prosthodontist or denturist, to make the denture. A denturist is a trained and licensed professional who sees patients in need of dentures, partials, relines or repairs. A denturist not only takes the impression, but makes the entire denture in his or her own laboratory. The denturist then schedules a date for the delivery of the finished dentures to the patient. A general dentist may do a good job making dentures, but only if he or she is meticulous and experienced. Many dentists no longer make dentures themselves. but instead take an impression of the patients' mouth and then either send the impressions to a dental laboratory, which could be anywhere in the world, or send the patient to a denturist. Once the laboratory receives dental impressions of the patient's mouth, the laboratory creates plaster molds from them. The laboratory uses the molds to create the wax rims used to register the patient's bite. These wax rims are returned to the dentist, who uses them to register the patient's bite. The dentist may assist the patient in choosing the correct size of teeth for the dentures, or simply make the selection himself. Once bite registration is completed and the teeth are selected for the dentures, the wax rim is usually returned to the dental laboratory in order to have the denture teeth set into the wax. Once the teeth are set into the wax rim, the result is a prefinished denture that looks almost like the finished product. This prefinished denture is usually returned to the dentist's office and the patient usually has a chance to approve the setup (for immediate or standard dentures) or to try the denture before it is finished. After approval by the patient, the dentist returns the pre-denture to the laboratory for final processing. The finished denture is then returned to the dentist's office for delivery to the patient.
Unlike conventional dentures, immediate dentures are made in advance and can be positioned as soon as the teeth are removed. As a result, the wearer does not have to be without teeth during the healing period. However, bones and gums shrink over time, especially during the healing period following tooth removal. Therefore a disadvantage of immediate dentures compared with conventional dentures is that they require more adjustments to fit properly during the healing process and generally should only be considered a temporary solution until conventional dentures can be made.
High-end dentures usually involve a great measure of dental artistry and utilize materials which simulate the natural look and color of teeth and gums to the highest degree possible. The teeth, normally made from composite acrylic resins, are designed to last a long time and often include a warranty against wear and tear, such as chipping and cracking. These life-like dentures can cost anywhere from $1,000 to $5,000 for a full set (upper and lower jaw).
In addition to the complications that are specific to the implant, abutments, and dentures, there are various oral health problems that can occur in patients with dentures. Patients should keep their teeth and gums clean, and visit the dentist every six months so problems, if they exist, can be identified and treated. The types of oral health problems that commonly affect patients with dentures include:
