Abstract
It is of interest to examine the Marginal Bone Loss (MBL) around a single titanium implant that was immediately loaded and implanted in a healed or new extraction site in the maxilla over a period of five years. This study involved 36 participants (21 men and 15 women, with an average age of 31 years), all of whom needed to have a single implant placed in the front maxillae. The average marginal bone loss (MBL) in extraction sockets increased by 0.27±0.18 mm after a year, 0.26± 0.17 mm after three years, and 0.21 ±0.18 mm after five years. The mean change in MBL for the group of healed ridges was 0.27± 0.18 mm for one year, 0.22±0.18 mm for three years, and 0.21± 0.17mm for five years. Thus, implants loaded immediately and positioned in either healed ridges or extraction sockets had a similar effect on the local bone.
