Description: Two experiments were conducted to investigate psychological changes accompanying the osseointegration denture implant procedure. In Experiment 1, 44 prosthodontic patients were divided into three groups: denture control, preosseointegration, and postosseointegration. Psychological status was assessed using the following questionnaires: MMPI, Coopersmith Self-Esteem Inventory, Body-Cathexis Scale, SCL-90, Revised Ways of Coping Checklist, Multidimensional Health Locus of Control Inventory, and the Expressed Acceptance of Self Scale. One-way ANOVA statistics did not reveal significant differences between groups on any dependent variables. In Experiment 2, psychological data (above measures, minus MMPI) were obtained from 11 preosseointegration patients at four time periods: less than 6 months prior to the first surgery, 1-3 months following the first surgery, 1 week after the second surgery and 1 month after bridge placement. A significant main effect of time was present on two dependent variables, anxiety and paranoid ideation. Significant differences were apparent when comparing specific time periods for the following variables: self-esteem, obsessive-compulsive, interpersonal sensitivity, hostility, avoidance, and self-acceptance. Results indicated that positive psychological changes do occur with the osseointegration procedure but that improvements diminish over time. A pattern was present for improvements to occur until completion of both surgeries, and then to dissipate following the second surgery. It is thought that positive psychological changes may diminish as expectations about the procedure are not met or after the novelty of the prosthesis wears off.
