The influence of bone mineral density and body mass index on resorption of edentulous jaws.

摘要: SUMMARY Objective. The aim of this study is to determine the relation osteoporosis and body mass index edentulous jaw bone resorption. Material methods. Study included 48 postmenopausal totally female patients, aged 50 84 years (average age 69.73), with period at least 2 after last tooth extraction. Bone mineral density was determined in femoral neck lumbar area L2-L4 by dual energy x-ray absorptiometry (DEXA) using Lunar DEXA DPX-NT, GE Medical Systems hardware. Body calculated (BMI (kg/m )) data from results. Lateral cephalogram (Pantomograph Trophycan C), radiological measurement symphysis mandible performed for each patient. Degree residual ridge resorption clinically on diagnostic casts anatomic impressions classification Kalk. Results. There no statistically significant difference between groups, comparing mandibu lar height changes (p=0.054) various degrees maxilla (p=0.743) (p=0.752) different contents. a correlation mandibular (p=0.004). Statistically also observed (p=0.049) (p=0.027) index. Conclusions. Resorption does not increase when decreases. More severe manifestation patients diminished
