Study Notes
Significance
- The incisive foramen serves as a stable anatomical landmark for identifying the maxillary canines and central incisors.
- Neurovascular bundles emerge through the incisive foramen and are positioned on the bone’s surface.
- A perpendicular line, drawn posterior to the center of the incisive papilla, acts as a biometric guide indicating the location of maxillary canines.
- Central incisors are positioned 8-10 mm anterior to the incisive papilla, providing additional reference points.
Clinical Consideration
- It is crucial to avoid compressing the incisive papilla during the impression procedure to ensure it remains a relief area of the maxillary edentulous foundation.
- Special care should be taken to accommodate the incisive papilla in denture designs.
Anterior (Greater) Palatine Foramen
- Located medial to the third molar, at the ridge's junction with the horizontal plates of the palatine bone.
- Generally, no relief is needed in the denture base over this area due to the nerve and blood vessels being sheltered in a groove covered by dense soft tissue.
Maxillary Tuberosity
- The maxillary tuberosity extends distal from the area around the second molar to the hamular notch and is often densely covered by fibrous connective tissue.
- Provides substantial support for dentures due to minimal compressibility of the underlying tissues.
- Issues to consider in maxillary denture construction include:
- Enlarged tuberosities with bilateral undercuts can hinder denture insertion and removal.
- Pendulous tuberosities may reduce interarch distance, particularly near the retromolar pad.
- An occlusal radiograph is essential before surgical removal of the tuberosity to avoid the risk of oro-antral fistulas.
- Managing severe undercuts within the tuberosity region may require reducing the undercut on the preferred chewing side.
- Placement of the last posterior tooth should avoid the tuberosity to ensure functionality and fit.
