Surgical treatment
Age of patient

Question 3

Answer 3

Skeletal deep bite
Skeletal open bite

Question 4

Brachycephalic / euryproscopic

Answer 4

Broad short face
Maxillary vertical deficiency, class II deep bite

Question 5

Dolichocephalic / leptoproscopic

Answer 5

Long narrow face
Vertical maxillary excess, often deficient zygomatic width, open bite

Question 6

Principles of space analysis

Answer 6

Analysis of space within arch
Comparison of amount of space available and space required from proper alignemnt
Performed from mesial of first permanent molar to mesial of other first molar

Question 7

Space available

Answer 7

Measure the arch from first molar to the other, over the contact points and Incisal edge of incisors

Question 8

Space required

Answer 8

Measure m-d width of each tooth ,including first molars
Add all widths together
Compare to space available

Question 9

Types of space analysis

Answer 9

Tanaka-johnson = mixed dentition analysis
Moyers = mixed dentition analysis
Bolton = tooth size analysis

Question 10

Moyers analysis

Answer 10

Uses sum of width of lower permanent incisors, takes total to prediction chart that will estimate the space needed for the unerupted or erupted premolars and canines per quadrant

Question 11

Tanaka Johnson prediction

Answer 11

Sum of width of lower incisors to predict the width of unerupted canines and premolars
No X-rays or prediction charts
Convenient and easy
Accuracy 75%
Sum of width of lower incisors, divide by 2, add 10.5 mm lower arch, 11.5 upper arch

Question 12

Bolton analysis

Answer 12

Tooth size analysis
Diagnostic tool
Determine arch compatibility
Helps determine size of a possible prosthetic replacement if needed
Ideal ratio 91.3 %

Question 13

Cast analysis

Answer 13

Asymmetries of a single arch
Spacing - diastemas
Crowding
Rotations

Question 14

Principles of tx planning

Answer 14

Problem list in priority order
Establish tx goals
Tx possibilities
Cost/risk vs benefit analysis
Choice of mechanotherapy
