Additionally, the study aims to assess the distribution of graft material and the extent of resorption occurring between baseline and 6 months post\u2010implant placement following transcrestal sinus augmentation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This study employed a transcrestal approach utilizing an osseodensification protocol for sinus augmentation with mineralized freeze\u2010dried bone allograft. Immediately post\u2010operatively, a standardized periapical radiograph (PA) was taken using a standardized paralleling device with bite registration material. Furthermore, a low\u2010volume cone beam computed tomography (CBCT) radiograph was obtained. Following a 6\u2010month healing period, both radiographs were repeated for analysis and comparison to baseline parameters.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 22 subjects completed the study. At 6 months post\u2010surgery, PA evaluations indicated a reduction in apical graft height (AGH) of 55.9%, endo\u2010sinus bone gain (ESBG) reduction of 29.6%, and elevated membrane apex (EMA) reduction of 8.4%. CBCT analysis showed slightly higher reductions, with AGH, ESBG, and EMA reductions of 60.4%, 32.6%, and 12.2%, respectively.

To overcome this, the maxillary sinus can be augmented through various techniques and with various materials. This study evaluated augmenting the sinus with a transcrestal approach utilizing a freeze\u2010dried bone allograft. At 6 months postoperatively, x\u2010ray evaluation demonstrated a reduction in graft height and endo\u2010sinus bone gain. Comparison of imaging techniques revealed statistical accuracy of both 2D and 3D models to detect changes in the graft material.<\/jats:p>\n
