What is a major disadvantage of immediate complete denture therapy?

Immediate complete denture therapy involves placing dentures immediately after tooth extraction. A significant disadvantage of this practice is the impossibility for anterior try-in. Since the teeth are extracted and the dentures are placed immediately, there is no opportunity to assess the fit and esthetics of the anterior (front) teeth before the final prosthesis is made.

This can lead to challenges in achieving proper occlusion and aesthetic outcomes. In contrast, a conventional denture allows for adjustments to be made based on the patient's feedback during a try-in phase before the final denture is completed. During the immediate placement, adjustments or modifications are often based purely on initial impressions without the benefit of patient input on aesthetics until after the dentures are set in place.

The other reasons listed relate to complications or concerns that can arise during the healing and adaptation phases but do not impact the fundamental process of customizing the anterior denture design in the manner that the impossibility for anterior try-in does. This lack of adaptability in immediate dentures can significantly affect patient satisfaction and result in the need for future adjustments.
