The history of complete denture impression procedures have been influenced largely by the development of impression materials from which new techniques arose. Selection of material is left to the decision of the dentist, who makes choices based on personal preferences and experience. The success of every complete denture relies on the fulfilment of the three basic properties of retention, stability, and support.
There was no support for the frequent textbook statement that the two-step procedure is necessary and superior to the one-step method. While some special clinical situations may benefit from other combinations of materials and techniques. Key words: Impression methods, material, complete denture prosthodontics, final impressions, Border moulding

Regarding function, it affects occlusion and speech ability in patients, as well as changes of their appearance, which may result in psychosocial decompensation. 4 Complete dentures are primarily mechanical devices but since they function in the oral cavity, they must be fashioned so that they are in harmony with the normal neuromuscular function. The history of complete denture impression procedures has been influenced
largely by the development of impression materials from which new techniques and ideas arose. 5 Stability of complete lower dentures has challenged dentists and patients alike. Making accurate final impression for complete dentures is a multistage process that involves a preliminary impression, a customized final impression tray and a final border impression. It is important to thoroughly examine the patient’s mouth and select the most appropriate impression technique. 7 The process of shaping impression material along the borders of an impression tray by manipulating the soft tissues to duplicate the contour and size of the vestibules is known as border molding. 5 December 2018
