Do patient satisfaction with two designs of implant supported removable overdentures ; ball attachment and magnets?
Sixteen patients completed the study. Patient satisfaction improved significantly between baseline and the new prosthesis with each attachment type for all domains of satisfaction (P<0.05). Ball attachments provided greater satisfaction in the domains of general satisfaction, stability and ability to chew (P<0.05). Patients' general satisfaction with ball attachment retained overdentures was greater than that for magnetic attachments; however, both designs provide significantly greater satisfaction than conventional dentures. In this study, the majority preferred to retain the ball attachment although one-third of patients actively chose the magnetic attachment.
The results do not confirm the diagnostic value of Doppler echocardiography of diastolic transmitral flow velocity for detecting ischaemia in anaesthetized patients undergoing dobutamine stress echocardiography during positive-pressure ventilation of the lungs.
