ProsthodonticsIn a bilateral distal extension RPD, abutment teeth are crucial for the stability and support of the prosthesis. However, it is not ideal to have retention buccally on one side and lingually on the other side as this can lead to tipping and rotation of the denture during function, compromising its stability. Instead, both buccal and lingual retention is preferred for a more balanced and predictable outcome.
