Critical evaluation of material and procedures used for the functional peripheral moulding of special trays

ABSTRACT

Border molding is done to record the peripheral margins of the denture and to ensure their extension to the sulcus reflection and in the post dam area in the maxilla. With the use of green stick compound for border moulding it is possible to record the border details accurately but it tends to be messy and it is difficult to determine the consistency and proper temperature. Therefore, the use of thermoplastic compound has been examined and recommended to be kept to a minimum due to the availability of simpler techniques and easy to handle and accurate materials. Students may now be introduced to the various techniques and materials for border moulding along with the concept behind the procedure. This will enable them to decide on their own which technique to employ and master. In this paper, a critical evaluation of the various materials and techniques used for border moulding of the special tray is given. It is not the authors' intention to criticize the current methods of teaching in our dental schools but to encourage the readers to broaden their vision of the often complex but fascinating craft of complete denture construction
