(PEEK) Housing Verses Metallic Housing of Ball and Socket Attachment on Retention of Mandibular Overdenture

Effect of Polyether Ether Ketone (PEEK) Housing Verses Metallic Housing of Ball and Socket Attachment on Retention of Mandibular Implant Retained Overdentures: Randomized Clinical Trial

The aim of this study is to compare the clinical effect of PEEK housing vs. metal housing in terms of retention and patient satisfaction
