A simple method of making a custom matrix for molar root lesions has been described. The matrix provides anatomic form to the restoration and reduces the chairside time required to contour and finish the restoration.
Restorative procedures which complement orthodontic treatment and which may be carried out by the orthodontist are summarized. The importance of planning, with the restorative requirements in mind and the maintenance of prepared space (individual tooth or abutment positions) in all three planes of space during the period of retention, is described. The importance of liaison regarding the timing of the placement of the definitive restoration, if it is to be carried out by another dental surgeon, is stressed.
Recent developments in amalgam alloys composite resin materials have highlighted the importance of meticulous restoration placement by the dentist. This paper discusses the selection and use of the matrix which is significant in both the quality and longevity of the final restoration.
