purpose of wearing dentures
- replace missing teeth and adjacent structures (esthetics)
- provide function (ability to eat and enunciation)
types of removable complete dentures (6)
- tissue-supported complete denture
- implant denture
- interim denture prosthesis
- immediate denture
- denture for primary teeth
removable dental prosthesis that replaces the entire dentition and associated structures of the maxilla or the manible and rests on the denture foundation area, the mucosal-coverd alveolar ridge
tissue-supported complete denture
a complete dental prosthesis that is supported in part or whole by one or more dental implants. The denture itself is not an implantable device.
a removable prosthesis that rests on one or more remaining natural teeth, tooth roots, and/or dental implants. AKA overlay prosthesis.
a removable dental prosthesis designed to enhance esthetics, stabilization, and or function for a limited period of time, after which it is to be replaced by a definitive prosthesis. Used to assist in determination of the therapeutic effectiveness of a specific treatment plan or in determining th eform and funciton of the planned definitive prosthesis.
interim denture prosthesis
a denture fabricated for placment immediately following the removal of a natural tooth or teeth. tends to loosen after the significant remodeling of bone and soft tissue that follows surgery
if teeth are congenitally missing or have been extracted due to rampant caries or trauma, this denture is used for primary teeth
denture for primary teeth
when is an immediate denture placed
same day teeth are extracted
When do most changes in residual ridges of an edentulous mouth occur?
Mandibular bone loss is generally how many times greater than maxillary?
detects adequacy of the width of the attached gingiva; locates frenal attachments and their proximity to the free gingiva; identifies the mucogingival junction
When should you prepare a patient for dentures?
before they get them
How long must an immediate denture remain in place?
new dentures should remain over healed ridges for how long?
Denture related bone changes result from (3)
- Alveolar ridge remodeling
- compenstations by the patient
- treatment by the dentist
alveolar ridge remodeling may lead to
- loss of denture support
- loss of facial height and lip support
- increase prominence of the chin
- tmj manifestations
- occlusal disharmony
What compensations might the patient make for dentures
- adjust the way they wear them
- use drugstore remedies (pads, adhesives, self-reline materials)
When are denture adhesives good to compensate for poorly designed, constructed or ill-fitting dentures?
Factors that influence the mucosa in denture patient (6)
- Aging (thinner)
- systemic conditions that alter host response
- xerostomia (from meds, not age)
- biofilm removal on denture and tissues
- wearing denture constantly
- fit and occlusion of denture
Lubrication (saliva reduces friciton/irritation
Retention (saliva important for suction of denture)
Radiation generally damages which glands?
Negative fluid balance is found in which patients?
Most common causes of xerostomia
- therapeutic radiation
- sjogern's syndrome
- emotional and anxiety states
- negative fluid balance
- nutritional and hormonal deficiencies
- Polyuric states
remedies for temporary relief of xerostomia
- saliva substitutes
- frequent rinsing w water
- sucking dry ice
- xylitol gumOral Pilocarpine
- Moisturizing products
increases salivary flow; used in head adn neck radiation patients; Rx only
moisturizing products to recommend for xerostomia (5)
- oral lubricants
- mouth rinses
- (biotene, salese, oasis, spry)
Principle causes of Lesions Under Dentures
- Ill-fitting dentures
- Inadequate oral hygiene
- continuous wearing of dentures
Sensory changes in denture patients
- Tactile sense (cant feel bones or nut shells, proprioception: may chew too hard)
- Taste (taste buds of palate are affected...not the tongue; odors not removed regularly)
located on the palate, rearely outside the confines of the bony ridges. Appears as a group of closely arranged, pebble-shaped, red, edematous projections
Inflammation of the gumes due to (5)
- trauma from ill-fitting dentures
- continuous dneture wearing
- reduced salivary flow
- lack of denture cleanliness
- aging dentures
Generalized Inflammation caused by
Oral candidiasis in the form of denture stomatitis
treatment for inflammatory lesions
- new denture
- anifungal medication
- massaging the tissue
ylcerative lesions can be related to?
overextended denture border
ulcerative lesion should be biopsied if persising longer than?
have patient return in how many days?
Contributing factors of angular cheilitis
- loss of vertical dimension
- riboflavin deficiency
- candida albicans infection
Prevention procedures with dentures (6)
- denture hygiene
- oral mucosa
- rest for the tissue
- diet and nutrition
- relief from xerostomia
- dental caries control for overdenture wearers
appointment frequency for denture wearers
no less than 1x per year
dental hygienist job for maintinance appt for a denture wearer
- pt history
- remove dentures
- clean w high power soln
- soften calculus
- use denture brush
methods for marking dentures
- printed enclosure
- copper vapor laser
- prepartion into denture
- indelible pen or ballpoint
- engraving tool
what to include when marking dentures
- blood type, vital drug or disease conditions
- dentist's registration or hospital number
