CD Long term review Flashcards
Give examples of soft tissue problems?
Infection - Usually asymp until late stage - Good OH is essential Hyperplasia Neoplasia
Signs of candidosis - soft tissue infec?
- Red palate defined by denture bearing areas
- Asymp until later stage
- Hyperplastic tissue
- Angular cheilitis
Causes of candidosis?
- Poor OH and denture hygiene
- Leaving denture in at night
- Excessive FWS - angular cheilitis
- Unretentive dentures - rocking
- Systemic disease - diabetes, immunocompromised
Management of candidosis?
Identify cause
Improve OH and denture hygiene (warm soapy water with toothbrush, leave in 1% bleach overnight, rinse)
Denture replacement
Topical antifungals - prescribe at try in stage, miconazole gel (contraindicated with warfarin), nystatin
pastilles
Soft tissue problems - features of hyperplasia?
Denture granuloma - due to chronic irritation from denture
Mix of hyperplasia and inflam
Can be fixed by trimming down denture or surgical removal if larger
Soft tissue problems - features of Neoplasia?
Cancer/dysplasia
- Can present as ulcers
- If suspicious or worrying lesion with no obvious cause - refer urgently
- If apparent cause obvious - manage and review in 1 week
- If not healed - refer
Hard tissue problems?
All related to alveolar resorption
Protrusive overclosure
- Combination of alveolar resorption and denture wear
- Tx - reline dentures, occlusal pivots, replacement or denture duplication with moderate changes in jaw relations
Examples of denture problems?
Abnormal wear
Wear of base - opposing Md tooth or against heels of Md denture
Diagnosis and management of denture fracture:
- Impact - isolated event (repair and advise), repeated fracture (reinforce denture)
- Fatigue - age of denture (replace), predisposing factors:
– Insufficient space
– Weakness
– Pronounced mx torus
– Lack of labial flange
Other solutions:
- Polycarbonate
- Injection moulded
- Tooth bonding
- Cast metal base - bonding between metal and acrylic
- Stainless steel mesh
- Vulcanite - carbon fibre, glass fibre, aramid
