2/19: Exam, Diagnosis and Treatment Planning for Edentulous Patients Flashcards
(45 cards)
What are the 3 types of denture occlusion arrangements?
- Balanced
- Non balanced
- Lingualized (can be used with 1,2)
What is balanced occlusion?
The bilateral, simultaneous, anterior and posterior occlusal contact of teeth in centric and eccentric positions
What is an indiciation of anatomic, balanced occlusion?
Young, healthy alveolar ridges
Good neuromuscular control
When you set balance occlusion, what is the only thing you cant control?
Incisal guidance
What is condylar guidance determined by?
Patient’s anatomy
What are monoplane occlusion indications?
Excessive inter-rdge distance
Skeletal class II, class III and crossbites
Successful previous F/F were monoplane
Limited oral dexterity
Severely resorbed ridges
What are the types of patient psychological classifications?
Philosophical
Exacting/critical
Hysterical
Indifferent
What makes up the philosophical patient?
- rational, calm, sensible, confident
- “you make them, ill wear them”
- majority of the patients
- prognosis good
What makes up the exacting/critical patient?
- methodical, precise
- somewhat difficult to please
- may try to dictate treatment
- may demand a written gurantee
- should make a special effort to be neat and organized when treating
What makes up a hysterical patient?
- in poor health
- neglected oral conditions
- may blame dentist for poor oral condition
- “bet you can’t make teeth that i can wear”
- dont make promises
What makes up the indifferent patient?
- unconcerned with appearance and chewing
- often persuaded by relatives to seek treatment
- diet often poor
- prognosis poor unless education successful
What are the main 3 things you should do with a edentulous patient?
- Make impressions of the mouth as the patient presents
- Measure existing VDO
- Record tooth shade
When taking the dental history, what should you record?
- chief concerns or why pnt is in the chair
- history of previous treatment
When taking the medical history, what should you record?
- overall health and current medications
- interactions causing xerostomia
What type of radiographic exam is preferred?
Panoramic
What should you evaluate in a radiographic exam on an edentulous patient?
pathosis: root tips, foreign bodies, impacted teeth
Mucosal thickness, foramen location
Describe the classes of occlusion from ideal to unfavorable
Ideal = Class I
Class II
unfavorable = class III
What is the ideal interarch space?
Space accomodates teeth and bases with esthetic result
What is the unfavorable interarch space?
Too little space or too much space (torque lever is applied to denture bases)
What is the ideal ridge form?
Square to gently rounded
What is the unfavorable ridge form?
Tall, thin, undercut
What is the ideal mm of tuberosities?
ideal: 5-6mm
minimum: 4mm
What happens if you have unilateral or bilateral undercuts?
Unilateral - may be ok
Bilalteral - may need surgical correction
What happens if you have sharp area of ridge?
Surgery needed
