2-3	320	3	98.3	96.0–99.3
3-4	217	5	95.4	91.5–97.6

5-6	88	5	87.0	78.6–92.2
6-7	49	4	78.9	67.2–86.8
7-8	33	1	75.7	62.5–84.8
8-9	16	0	75.7	62.5–84.8
9-10	5	0	75.7	62.5–84.8
10-11	2	1	37.8	1.6–79.3
11-12	1	0	37.8	1.6–79.3

The Kaplan–Meier method is used to determine the survival rate of the implant. The analysis was performed on 1279 osseointegrated implants during 11 years of functionality.
