Denture-induced changes of the oral mucosa comprise, besides denture stomatitis and inflammatory papillary hyperplasia, the so called folds and redundancies in sulci and flabby ridges. The present article deals with these two tissue reactions which are associated with chronically ill-fitting dentures.
The postinsertion problems of complete denture prostheses are closely related to accurate recording of maxillomandibular relationships. It is essential that these recordings be made with stable record bases; making the final impressions within the record bases prevents movement and tilting. Face-bow and centric relation records properly orient the casts in the articulator. A method to obtain all of these records in one dental appointments has been described.
A case is described of application of the immediate overdenture technique to restore function, speech and aesthetics in a patient with extreme resorption of the maxillary anterior residual ridge. In the opinion of the authors, retention of the roots of the remaining teeth most definitely contributed to the retention, stability and overall success of the denture (Figs. 9, 10).

Teeth that are unsuitable as abutments for a fixed bridge or removable partial denture may be retained as roots under an overdenture. While these roots remain, the vertical height of the bony ridge is preserved. In addition, the roots give support to the denture and reduce stress on the alveolar ridge.
Tetracycline hydrocholoride was administered to label reparative dentin in teeth indicated for extraction. Deep cavities or pulp capping performed on the teeth one of four months before extraction served as a stimulus for new dentin formation. Examination of undemineralized sections under ultraviolet light revealed fluorescent bands in the reparative dentin of most teeth. The technique can be safely used in studies of the effects of clinical procedures on the dentin and pulp of human teeth.
