Psychological impact of osseointegrated dental implants

This longitudinal study of 39 patients who underwent treatment involving osseointegrated implants examined problems in oral and psychosocial functioning, expectations and experiences of difficulties with surgery, satisfaction with surgery, body image, neuroticism, self-concept, and extroversion. Patients completed six questionnaires from before phase 1 surgery to the final recall appointment for the new prosthesis (12 to 18 months after phase 1 surgery). The most common problems reported before treatment were those associated with eating; esthetics was less of a concern. Significant improvements in all problem areas were observed immediately after phase 2 surgery. Expectations of surgery-related problems were generally consistent with experiences immediately after phase 1 surgery, but more negative than experiences following phase 2 surgery. Body image before treatment was most negative vis-à-vis teeth. Significant improvements were found not only regarding teeth, but also on facial, mouth, and even overall body image. Satisfaction scores were generally high, but showed continued improvements through the final assessment. The only group experiencing negative outcomes consisted of patients scoring high on neuroticism.
