Modified overdentures for the management of oligodontia and developmental defects.

A technique for the construction of complete dentures over unaltered natural teeth has been described and illustrated for three different situations. The procedure is straightforward and simple and varies only slightly from conventional overdenture construction. The technique offers several advantages for a patient who wishes to keep the remaining natural teeth unaltered but who requires significant functional or esthetic improvement. Since the teeth are unaltered, any type of future treatment may be considered at any time without being compromised. This is an important factor to consider for the young patient. The cost, when compared to the fabrication of a fixed or cast removable prosthesis, is significantly less, while still providing acceptable esthetics and function. The versatility of this procedure allows its use in a number of situations which are not amenable to more complicated treatment methods.
