I-spacer in maxillary arch, based on selective-pressure technique, covers the incisive papilla and midpalatine raphe when it is prominent (Figure 13).
It is based on selective-pressure technique; it also covers the prominent incisive papilla, rugae and midpalatine raphe, and the exposed areas act as stoppers.
* Tin foil, first recommended by Roy Mac Gregory in the region of incisive papilla and midpalatine raphe.
The maxillary denture rested on reabsorbed maxillary bone and hyper-movable anterior crest with marked incisive papilla. The prosthesis bordered and pressured this papilla irritating this area (Fig.
The anatomical connections from the incisive papilla, the vascular patterns and the somatosensorial distribution may clarify the referred symptoms and the pathophysiological justification based on these associations.
Massive vascular effects on efferent nerves can be expected when it is taken into account that the abnormal sensorial and vegetative input coming from the incisive papilla trauma can excite potent vasodilator-mediated afferent nerves (Ertsey et al.).
The trauma in the incisive papilla area can involve nociceptive, sympathetic and parasympathetic sensorial impulses.
Sphenopalatine artery (greater incisive artery) septal branch irrigation emerges in the incisive papilla area providing irrigation for the nasal septum; this is mixed with the superior lip and ophthalmic artery and also vasomotorinnervated by the SG.
The palatal gingival margin, Scar line, Inner surface of the maxillary denture border corresponding to cephalometric point sub-spinale and incisive papilla are used .The incisive papilla is reported to be a reliable anatomic landmark in the arrangement of anterior teeth.
Incisive Papilla covers the incisive foramen and is located on the median line behind and between the central Incisors.
The available reference is grouped under two headings; the relation of incisive papilla to maxillary central incisor and canine teeth.
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.
