Example 4

A female peri-implantitis patient, 66 years old and non-smoker, had severe bone loss at two implant sites (as shown in FIG. 4A). The patient took during one year 5 drops of BioSil® liquid twice daily. This formulation contains choline-stabilized orthosilicic acid (ch-OSA®), wherein silicic acid is stabilized with choline chloride. The formulation furthermore contains glycerol as a diluent. After one year the bone level was significantly increased at the implant site (see FIG. 4B).

A second peri-implantitis patient, 73 years and non-smoker, with severe bone loss at the implant sites and damaged gingiva (FIG. 5a) took during one year 5 drops of BioSil® liquid twice daily. After one year the bone level was also significantly increased at the implant site (FIG. 5b, after 6 months, FIG. 5c, after 12 months). FIG. 6 shows that the gingiva regained its normal appearance with good color indicating improved vascularization in the course of the 1 year treatment.

The following treatment examples can be used as an adjunct to good mouth hygiene, scaling and root planing:
