Table 2 Number of implants placed according to length and diameter. Table 3 Number of implants placed and failed, success rate and mean bone loss according to immediate or delayed placement of implants. Table 4 Number of implants, success rate and mean bone loss in relation to smoking. Table 5 Number of implants, success rate and mean bone loss in relation to oral hygiene.
