Assessment of bone healing around immediately loading dental implants in posterior maxilla with two different osteotomy techniques

The posterior region of the maxilla is characterized by thin cortical bone and trabecular bone of low density. In addition, in many instances the height of the bone in this region is insufficient to achieve high primary stability because of the presence of the maxillary sinus. The aim of this study was to assess bone healing around immediately loaded dental implants in posterior maxillary region with two different osteotomy techniques, conventional technique versus condensing technique. Twenty implants were inserted in ten patients each patient received two implants. One implant was inserted by conventional technique other implant was inserted by condensing technique one on each side of maxilla. The follow up was done at the following intervals, immediate post-operative, six weeks, twelve weeks, and twenty four weeks. One implant from the group of condensing technique showed failure after four weeks. The results of this research demonstrate the success rate was 90% for condensing group and 100% for conventional group.
