Clinical examination of a partially edentulous 66-year-old male revealed a large asymptomatic denture fibroma-like hyperplasia in the junction of the floor of the mouth and the posterior alveolar ridge on the right side of the oral cavity which was arbitrarily named a fibrosis. A chord of gingival and mucosal tissue was found in the same area on the left side.
The fibrosis was 38mm in length, 7mm in width, and 8mm in height.
As a consequence of the loss of posterior mandibular occlusal support, the right upper molars over-erupted and the third molar was in contact with the corresponding inferior alveolar ridge.
An immediate partial denture was made and lined with tissue conditioner in the area corresponding to the fibrosis. This denture was designed to prevent the mechanical stimulus of chewing the fibrosis. The size of the fibrosis reduced gradually, and denture base adjustment and linings were made respectively. The fibrosis became a chord of tissue similar to the one on the left side and not shown any apparent change in a 5-month period.
It was thought that the chronic mechanical stimulation of masticatory function played an important role in the development of the fibrosis.
