Three-Dimensional Positional Changes of Teeth Adjacent to Posterior Edentulous Spaces in Relation to Age at Time of Tooth Loss and Elapsed Time

Abstract - The purpose of this study was to study the stability of teeth adjacent to posterior edentulous spaces and correlate it with patient age and time lapse since tooth loss. Dental casts, panoramic radiographs, and questionnaires of patients treated in a University setting were employed. Teeth adjacent and opposing posterior edentulous spaces were examined for the following parameters: Supraeruption, rotation, space closure, and axial inclination. One hundred twenty three patients with 229 edentulous spaces were analyzed. Statistical analysis showed that the effects of “jaw”, “gender”, and “age group at the time of tooth loss” were not significant for any of the variables tested. The effect of time lapse since tooth loss was significant regarding the “amount of distal tooth inclination” (P<0.001), the “amount of distal tooth rotation” (P=0.004), and “space closure” (P=0.038). Post-hoc analysis of the “amount of distal tooth inclination” revealed a marked increase in inclination 5 years after tooth loss. Within the limitations of this study, it was concluded that in the group of patients studied, minor positional changes in teeth opposing or adjacent to posterior edentulous spaces had occurred. The greatest changes in position were recorded for mandibular teeth distal to edentulous spaces.

KEY WORDS: Age, tooth movement, supraeruption, edentulous, space, extraction.
