One of the earliest reference on the incisive papilla as a guide was that of Harper, who studied the preextraction and post-resorption models of the same case and concluded that there is no change in the position or dimension of the incisive papilla from the dentate to the edentulous stage.

9 The usefulness of the incisive papilla as a guide was also determined by Grave et al and suggested that the labial surface of the incisors should be 12-13mm from the posterior border of the incisive papilla.
Esa Klemetti et al studied the location of the incisive papilla along with the palatal gingival margin as a function of factors affecting the residual ridge in the edentulous maxilla, such as duration of edentulousness and skeletal mineral status.
They concluded that the anterior movement of the incisive papilla caused by progressive residual ridge resorption also originates from this flattening.
