Behaviour bone quality during implant treatment monitoring was conducted on ten patients with an age range from 25 to 55 years old. Monitoring is carried out in three stages: immediate, three months, and four months after implant placement. In general, the mean density decreased from stage 1 to stage 2 (significant P = 0.17) and increased again from stage 2 to stage 3 (significant P = 0.122). Density, cortical thickness, bone width, and height are correlated with primary implant stability. Meanwhile, the secondary implant stability is correlated only with density progress during the monitoring period.
