Abstract
Background, Failure to replace a missing posterior tooth is assumed to resu lt in a host of adverse consequences; which include shifting of teeth and l oss pf alveolar bane support. Methods, A retrospective longitudinal study (median follow-up period 6.9 ye ars), using the radiographs of 111 patients who had an untreated bounded ed entulous space, or BES, was conducted to determine the extent to which thes e adverse outcomes occurred. Results, The majority of patients lost 1 millimeter or less of the distance between teeth adjacent to the space, extrusion of the opposing tooth was l ess than or equal to 1 mm in 99 percent of the cases, and the amount of alv eolar bone loss next to the adjacent teeth was less than or equal to 1 mm i n 83 percent of the cases. Conclusions. Within the follow-up time in this study, this group of patient s did not exhibit the expected adverse consequences with either the frequen cy or severity generally assumed to be associated with nonreplacement of a single posterior tooth. Clinical Implications. These findings suggest that for the large majority o f patients who experience a single-tooth posterior BES, immediate treatment may not be critical to the maintenance of arch stability. Instead, regular follow-up assessments to monitor change in stability and periodontal healt h may be warranted.
