Fig. 7 Regular-IT group: implant inserted in the mandible, radiograph at 24 months. Figs. 6 & 7 after24months.Afterthefirstyear,themarginal bone around the implants remained stable, re- gistering a decrease of 0.75 ± 0.28 mm at 24 months (Table 2). The FSTL values were analyzed in the man- dible and maxilla in the high-IT and regular-IT groups (Table 3). In the maxilla, the FSTLvalues at baseline were homogeneous for the two groups. After one year, a decrease in FSTL was registered in both groups (-0.60 ± 0.49 mm in the high-IT group and -0.07 ± 0.26 mm in the regular-IT group), but at the 24-month recall, both the regular-IT group and the high-IT group showed a slight increase. Despite this, the dif- ference betweenthetwo groupswas significant at each time point. The ΔFSTL underlined the one-year decrease and the two-year increase in the soft-tissue level, besides the clear dif- ferences between the two groups at each time point. The FSTL values in the mandible showed a decrease in both groups after 12 months (-0.90 ± 0.48 mm in the high-IT group and -0.13 ± 0.34 mm in the regular-IT group). After two years, the high-IT group remained stable, while the regular-IT group showed an increase in FSTL. The difference in ΔFSTL between the regular-IT and high-IT groups was significant at the one-year follow-up and even more evident at the two-year follow-up. Volume 2 | Issue 4/201669
