To Evaluate the Complete Mandibular Dentures Produced Via 3D Printing in Comparison to Those Constructed From Metal-reinforced Acrylic Resin Regarding Their Retention

Comparative Study of Retention of Mandibular Denture Bases Three-dimensional (3D) Printing Technique and Metal-reinforced Acrylic Resin

in this study we will construct denture for patient by different way and material one of this denture constructed digitally and the other one constructed in conventional way with metal reinforced. then we will measure the retention of the dentures

the complete denture is constructed for completely edentulous patient. the different technique of construction aim to increase retention of denture to prevent dislodgment during mastication
