ABSTRACT
Because the arrangement of the remaining dentition may vary tremendously, the design of a removable partial denture is complicated with regard to function, esthetics, hygiene and oral comfort. Part One of this article, published in the January/February issue of JDT discussed how disassembling the RPD into its structural components and defining their functions could help the dental technician with RPD planning. Part two discusses the connection of partial frameworks to the remaining dentition and breaks down the components of a combination case.

Because the arrangement of the remaining dentition may vary tremendously, the design of a removable partial denture is complicated with regard to function, esthetics, hygiene and oral comfort. Part One of this article will discuss how disassembling the RPD into its structural components and defining their functions will help the dental technician with RPD planning. Part Two will break down the components of a combination case using the same systematic approach.

Elderly people tend to gradually lose more of their ability to adjust. This pertains as much to changes within the oral cavity as to the general things in life. It is, therefore, advisable to make only small changes within the oral cavity at any one time. The goal of producing a complete denture should be attained in small steps with the aid of 'add on dentures'. Existing, successfully worn, complete dentures which have become inadequate, should not be replaced but should be rebuilt step by step. In addition, a 6 month recall system is strongly recommended.

Our examination of elderly and ageing patients presented four essential classifications, including those with: 1. sufficient natural dentition; 2. dentition, with numerous missing teeth, in need of functional restoration; 3. groups of teeth remaining, but on the verge of edentulousness; 4. edentulousness with dentures in need or replacement or improvement. For the above, we recommend the following treatments, respectively: 1) prophylactic topical fluoride treatments with custom trays; 2) extendable hybrid constructions--preferably with the implementation of a telescoping design; 3) partial dentures designed for easy extension; 4) no new dentures, but rather the step-by-step correction of the old dentures.

If aged patients who have been wearing their full dentures without complications so far, need further prothetic treatment, the dentist must not replace the old denture by a completely new one. It is better to rebuild it step by step. This demand is based on the following theses: --Nobody but the patient himself is able to perform functional movements. --Unless bite and occlusion are correct, patients are not able to perform accurate functional movements. --When bite and occlusion have been checked and, if necessary, improved, bases and alveolar ridges must be congruent.

A particular problem in the prosthodontic treatment of aged persons is their diminished ability to adapt to changes. Consequently, this requires an incremental treatment plan for changes in the mouth. In many cases it is preferable to modify an existing denture step by step instead of constructing a new one. Where extractions are necessary, immediate replacements should be provided, if this aids the patient stereognostically. The extraction of all remaining teeth should be done in a prolonged step-by-step procedure and with the use of an extendible denture. Continued care is imperative. Important factors to be considered are denture maintenance, esthetics and the multimorbidity of the geriatric patient.
