Over nearly 80 years or so I have been to countless numbers of dentists both NHS and private and with one exception they have all given me very good service. However one thing has stood out like a sore thumb and that is the highly variable and generally poor quality of partial dentures, both acrylic and chrome and both NHS and private.. For reasons that are beyond me dental technicians seem to find it difficult to design and produce clasps which are sturdy and capable of lasting for any length of time. In my case, with lower front partials, the clasps usually break in less than 3 months particularly the puny looking pieces of stainless wire which is used for many clasps and the chrome partials have not lasted much longer. Is this normal?
