Chpt 5: history taking Flashcards
edentulous people have lost a body part and are considered
physically impaired
what is used to establish the anterior occlusal plane
interpupillary line
what is used to establish the posterior occlusal plane
ala-tragus line (camper’s line)
what is used to determine position of condyle
canthus tragus line
how to restore the normal contour of naso labial sulcus
- proper positioning of anterior teeth
- proper contour of upper labial flange
what can affect the mento-labial sulcus
malocclusion (class I, II, III)
what folds are restored by denture
- naso labial fold
- philtrum
- modiolus
the amount of vermillion border depends on
- bulk of orbicularis oris m
- amount of labial alveolar bone
- alignment of ant teeth
the ultimate objective of the 1st appointment is
development of tx plan that addresses and accommodates the patient’s needs
extra-oral evaluations
- TMJ joint
- lips and cheek
- fascial asymmetries
intra-oral examination
- mucosa
- tongue
- saliva
- residual ridge morphology and ridge relations
- tori, undercuts, enlarged tuberosities
- teeth (when present)
other aspects to consider when doing examination
- existing prostheses and their occlusal relationship
- x rays
- study casts
what are 2 critical elements to consider in managing adaptive and maladaptive denture wearing pts
- behaviour of doctor
- thorough patient interview
4 parts of the interview
- recognition of problem
- identification/exploration
- interpret/explain
- offer solution
symptoms of TMD
- pain/tenderness in mm of mastication and TMJ
- joint sounds during condylar movements
- limitations of mand movements
evidence of inadequate lip support
rolled-in vermilion border
masticatory mucosa
mucosa covering the residual alveolar ridges and palate
major source of tissue trauma
- incorrect occlusion
- overextended or underextended borders
angular cheilitis may indicate
candida albicans infection
papillary hyperplasia
- cauliflower-like appearance
- anterior region of palate
- prone to candida infection
- tissue should be removed, infection needs to be treated, then make a new denture
what properties of saliva are important for denture success
flow rate and viscosity
how should the mylohyoid mm be when taking impression
contracted; if not, when they are contracted the denture will dislodge
what can happen if you dont wear a denture for a while (esp mand denture)
- tongue enlargement (from using it more)
- mylohyoid / FOM spreads out over the mand ridge
plaque that causes poor denture fit is usually found on the
tissue surface of labial flange
buccal sulci
located distal to buccal frenula
masseter m can act through buccinator to
impinge on buccal sulcus (more pronounced in mandibular)
lateral boundary of buccal shelf and buccal sulcus
external oblique line
how to determine the vibrating line position (line btw hard and soft palate)
saying the letter K
what determines the depth of posterior palatal seal
extent of tissue anterior to vibrating line is displaced
