When performing an extraction for an immediate denture, which teeth are typically preserved?

In the context of preparing for an immediate denture, the teeth that are typically preserved are those that will provide adequate support and aesthetics for the prosthesis. The preservation of specific teeth, such as teeth 12 and 21, which are usually the maxillary and mandibular canines, is crucial because these teeth are strategically positioned to offer stability for the denture and maintain the natural appearance of the smile.

The canines are considered key teeth in the dental arch due to their position, roots, and ability to help in maintaining the arch form, especially when immediate dentures are being placed. By preserving these teeth, the practitioner ensures that there is a solid foundation for the immediate denture, which can improve patient comfort and functionality while mitigating the risks associated with extraction of too many teeth at once.

In contrast, preserving all anterior teeth or all molars may not provide the same level of functional support or aesthetic outcome as preserving specifically selected canines. The primary focus is on maintaining teeth that enhance the immediate denture's performance while considering the overall condition of the remaining dentition and the aesthetic result for the patient.
