FACTORS IN IMPLANT INTEGRATION FAILURE AFTER BONE-GRAFTING - AN OSTEOMETRIC AND ENDOCRINOLOGIC MATCHED ANALYSIS

In a retrospective analysis of 49 patients who received bone graft aug mentation to the maxillary sinuses in conjunction with implant inserti on, 11 patients had a significantly reduced success rate. The aim of t he present study was to determine whether bone quality, as assessed by osteometry and selected haematologic and urinary tests, influences th e integration of implants, and whether such data can be prognostically useful. Relative bone mass density (BMD%) differed significantly amon g these patients as compared to age- and sex-matched control patients receiving the same reconstructive treatment (P= 0.01). Other parameter s tested did not demonstrate any significant differences. In addition to local complications, general disorders, such as osteoporosis, must be considered in cases of excessive implant loss.
