In the traditional type, the interim prosthesis is fabricated to immediately place after the extraction of natural teeth and can be used as the definitive or long-term prosthesis. 1,3 The in- terim type is used for a short time after tooth extrac- tion. After the achievement of healing period, the im- mediate denture may be relined or replaced with the newly fabricated final denture. 4 The immediate denture treatment maintains patient’s appearance, circumoral sup- port; muscle tone, vertical dimension of occlusion; jaw relation and face height. 1,5 The patient’s psychological and social well-being is preserved. There is less postopera- tive pain as extraction sites are protected. It is easier to duplicate natural tooth shape and position. Speech and mastication are rarely compromised and nutrition can bemaintained. 1,6 Immediate dentures are more challeng- ing modality than complete dentures because the pres- ence of teeth makes impressions and maxillomandibular positions more difficult to record. 7 The anterior ridge undercut caused by presence of remaining teeth may interfere with the impression procedures. 8 Presence of different numbers of remaining teeth in various loca- tions can lead to incorrect recording of the centric rela- Abstract The immediate denture is a dental prosthesis constructed to replace the lost dentition, associated structures of the ma xillae and mandible and inserted immediately following removal of the remaining teeth. The purpose of the present clinical report is to describe the use of a sectional impression tray technique that can prevent extraction of supporting teeth of patient’s extensive fixed prosthesis, where the teeth were hopeless and fabricating an interim immediate complete denture was a treatment option to prevent patient’s distress, anxiety and embarrassment. The present procedure was used to replicate the vertical dimension, phonetic and aesthetic of the existing fixed prostheses as part of an immediate denture and a final complete denture.
