Factors influencing vertical ridge dimensions in mandibular molar edentulous site - An Observational study
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 1
Abstract
The purpose of this study was to determine the influence of –“reason for extraction” and the “span of edentulousness” in the occurrence of vertical ridge deficiencies in mandibular molar region. A total of 71 patients with single molar edentulous sites were included in the study and the reason for extraction was obtained through a detailed case history. Intra oral periapical radiographs were obtained of the selected sites and the vertical distance measured from a line connecting the adjacent cementoenamel junctions to the crest of the remaining bone. The vertical ridge deficiencies were categorized as mild,moderate or severe. It was observed from our study that, severe vertical ridge deficiencies are mostly associated with extraction due periodontal disease and the keratinized tissue loss is in agreement with the severity of ridge deficiency. It was also inferred thatthe span of edentulousnessis directly proportional to the loss of vertical bone height.
