Abstract
The aim of this study was to evaluate the effect of secondarily splinting implant analogues with resin prior to impression pouring on the passive fit of screw - retained frameworks using single screw test. The sample of this study consisted of ten patients; All patients were completely edentulous, free of systemic diseases and with adequate interarch distance. The patients received four implants in each arch. Two impression pouring techniques were obtained. Technique 1: master casts generated from non - splinted coping impression technique and the impressions were poured directly without splinting the implant analogues. Technique 2: master casts generated from non - splinted coping impression technique, while implant analogues were splinted with autoploymerized acrylic resin before pouring. Single screw test was used to evaluate the passivity
