Comparative Study
Experiments with various casting techniques have been done, and aluminum base dentures have been made for many patients. The subjective clinical response from patients wearing aluminum dentures has not been different from patients wearing acrylic resin dentures. However, Brudvik and Holt have stated that they have had marked clinical success in using aluminum bases. A literature review on using aluminum as a denture base material has been presented, and the rationale for its use has been discussed. In part II, a technique will be described that can be used for casting aluminum denture bases.

Complete maxillary dentures are one of the most economic and easy ways of treatment for edentulous patients and are still widely used. However, their survival rate is slightly above three years. It is presumed that the failure reasons are not only due to normal fatigue but also emerge from damage based on unavoidable improper usage. Failure types other than long-term fatigue, such as over-deforming, also influence the effective life span of dentures. A hypothesis is presumed, stating that the premature/unexpected failures may be initiated by impact on dentures, which can be related to dropping them on the ground or other effects such as biting crispy food. Thus, the behavior of a complete maxillary denture under impact loading due to drop on a rigid surface was investigated using the finite element method utilizing explicit time integration and a rate-sensitive elastoplastic material model of polymethylmethacrylate (PMMA). Local permanent deformations have been observed along with an emphasis on frenulum region of the denture, regardless of the point of impact. Contact stresses at the tooth-denture base were also investigated. The spread of energy within the structure via wave propagation is seen to play a critical role in this fact. Stress-wave propagation is also seen to be an important factor that decreases the denture's fatigue life.

Improvement in the interim denture procedure in the past decade has been one of the significant advancements in prosthodontic practice. The interim denture approach is only slightly more time-consuming and expensive than the conventional immediate denture approach, yet it has many advantages. Among those advantages are the following: (1) allows rapid results; (2) results in a higher quality definitive denture; (3) allows the surgical treatment to be performed during one appointment; (4) permits duplication of the natural tooth position; and (5) provides the patient with a spare denture after the definitive denture is completed. An interim denture technique was described that utilized a flexible layered silicone mold to form the replaced teeth. The interim denture procedure is flexible and lends itself to many variations in technique to meet unusual clinical situations. An interim removable partial denture technique was described that involves block-out of undesirable undercuts and duplication of the master cast for fabrication of the partial denture. This technique results in an interim partial denture that can be placed with little or no adjustment and that will provide better service for those who require it. Three simple procedures for fabricating treatment dentures were described and the indications for each were discussed. Although treatment dentures are not often used, they are essential for the dentist who is treating difficult patients who require complete dentures.

Review
Two telephone surveys requested patients to report on their use of removable partial dentures that were constructed by undergraduate dental students. In the first survey, of the 431 patients called, 290 were contacted and interviewed 24 to 33 months after their removable partial denture(s) had been inserted. Of these, 258 patients reported using their prostheses and 238 had no apparent problems. In the second survey, the 238 trouble-free removable partial denture wearers from the first survey were called and 169 were contacted and interviewed 48 to 57 months after the removable partial dentures had been inserted. Of these, 156 reported still using their prosthesis and 152 had no apparent problems. These data are provided, along with some interpretive caveats, for dentists to use in discussing treatment options with patients.
