简要总结
The aim of the current study is to assess the effect of two types of attachments (Locator, Novaloc) on the supporting structures both mechanically using stress strain analysis and biologically through measuring bone height using cbct.
详细描述
14 Completely edentulous patients will be divided into two groups each group contains seven patients: Group One: Each patient will be restored with 4 implant retained maxillary overdenture using Peek retention inserts attachment system and Bone Level Ti-Zr implants.
Group Two: Each patient will be restored with 4 implant retained maxillary overdenture using Nylon retention insert attachment system and Bone Level Ti implants.
Bone height in millimeters will then be evaluated around each implant using cone beam computed tomography at the time of placement of attachments, 6 months, 1 year
