title: Osseoretention? Comparative assessment of particulate hydroxyapatite inserted beneath immediate dentures.
abstract: This paper presents the results of a study to observe the effect on bone resorption and residual alveolar ridge form, of placement of dense non-resorbable hydroxyapatite granules into fresh canine sockets, at the time of immediate denture provision. Thirty five subjects were randomly divided into two groups cross matched for age and sex. All subjects required bilateral extraction of at least a lower canine and an adjacent tooth. Results demonstrate that six months post-extraction the control group had lost four times more bone than the implant group. These results were highly significant (P=0.000, LHS and P=0.001, RHS).
