The effect of different techniques and materials on peripheral shaping of the complete denture impressions were investigated by stereophotogrammetric method. Six impressions were taken from each of the 20 edentulous patients by using two different techniques and three impression materials. A non-metric camera was used to produce stereo paired photographs of each model. The measurements were made at the buccal vestibule regions, labial vestibule regions and labial frenilum region on 120 casts. When buccal vestibule regions were evaluated no statistically significant difference was found between double phase and mono phase impression materials.
