Brief Summary

Since the teeth loss leads to disability \& impairment, and teeth restoration lead to improvement in the life quality throughout the oral health improvement. The acceptable function of a complete denture on great extent depends on impression technique which includes the maximum coverage of denture supporting areas and making a combination of managing movable soft tissues along with different kinds of impression materials and techniques for accurate reproduction of oral foundation. Border molding considered to be as an important step in the in complete denture fabrication, since the retention of complete dentures depend on several factors, as the biological, physical and mechanical, these factors could be achieved by mean of an accurate border molding followed by an accurate final impression. The border molding technique is the shaping of the border areas of a custom impression tray by manual or functional manipulation of the tissue adjacent to the borders in order to duplicate the size and contour of the vestibule resulting in maintains of the peripheral seal during function. This property causes the border molding process to require twenty-four insertions, namely eight in the maxilla and sixteen in the mandible causing long working time and discomfort in patients. Hence, the material used for this technique should provide optimum working time, have adequate body, and permit the correction of border moulding by additions. However additions if made to a single step border moulded material would again introduce all the disadvantages that are associated with sectional moulding Single-step border molding is considerably more straightforward than sectional border molding owing to the reduced number of tray insertions. This technique is usually used with elastomeric impression materials, which may not provide sufficient time to mold and record the peripheral tissues of the denture bearing area. The present technique uses light polymerizing tray material for molding tray borders, offering extended working time. This is advantageous for operators with less experience, such as dental school students. Furthermore, correction of border molding is possible with the addition of new material. The technique uses materials that are readily available,and no special armamentarium is required.
