Post-Insertion Problems - 72
- may be retentive for a while if a lip seal established, until movement disturbs the lip
seal
Long flanges
- burn through (PIP)
- intrudes tissue when placed
- may not dislodge if good seal, may loosen after much function or hyperfunction
Post-palatal seal
- if the denture is short of the vibrating line, the denture may bind on hard palate,
(check with PIP)
- if there is inadequate tissue contact, food may get underneath the denture, bubbles
may extrude as the denture is placed
(check intraorally with PIP)
- if over-extended to the movable portion of the soft palate, the denture may drop
during speaking, eating
4. Occlusal Vertical Dimension (OVD)
- continual and generalized pain and fatigue or muscle soreness (excessive OVD)
- no power (insufficient OVD)
5. Allergies and Infections
- rare allergies - general inflammation
- hygiene - generalized inflammation
6. Tooth Position
- instability (teeth not over ridge)
- difficulty chewing (occlusal table not long enough -esp. rational teeth)
- check and lip biting (insufficient overjet)
- esthetic, phonetic problems
- may have to grind off teeth and reset
Most Common Areas Requiring Adjustments
Maxillary
Hamular notches – ulceration can occur if over-extended
Labial frenum – requires adequate relief (often feels too bulky to the patient)
Mid-line fulcrum on the bony raphe
Zygomatic impingement
Mandibular
Lingual frenum – impingement can cause displacement of the denture or ulceration
Retromylohyoid overextensions - sore throat; denture moves when swallowing
Buccal shelf overextention
Phonetic problems - wait and allow time for adaption
- add soft wax to palate and check
- if anterior poorly positioned, then remove and replace
