Study the Effect of Two Different Types of Attachment Systems on strain of Mandibular complete Overdentures Retained by Midline Implant

Aim: This study was conducted to evaluate the effect ball and equator attachments strain (invitro study) of mandibular over denture retained by single midline implant for completely edentulous patient. Subjects methods: Ten complete lower dentures have attachment another ten were constructed on acrylic models covered rubber material simulate oral mucosa implant, evaluated around in posterior area using meter after unilateral bilateral loading universal testing machine each abutment individually.
