• Commitment and Motivation
• Differing Occlusal Concepts
• Sectional Arch Treatment
• Prefabrication of Appliance
• Functional Influences
• Three Phase of Retention
www.indiandentalacademy.com
33. Occlusal Check List for Lower
• Molar - upright , mesial slightly outward to accommodate distal
incline of upper first bicuspid.
• Bicuspid (2) - slightly depressed to seat the upper second
bicuspid.
• Bicuspid (1) – buccal to lower canine and should be well
elevated, mesial contact also buccal to canine.
• Lingual crown torque from bicuspid (2).
• Canine – position to produce smooth curve.
• Distal of lateral placed slightly labial to mesial of canine.
• Smooth curve of contacts of the incisors.
www.indiandentalacademy.com
34. Occlusal Check List for Upper
• Molar – well expanded to prevent collapse of arch later.
• Molar – upper molar rotation . Line should pass through canine.
• Bicuspid (2) – distal margin is well occlusal to marginal ridge of
upper first molar. Slightly inclined mesially.
• Bicuspid (1) – slightly distally inclined.
• Bicuspid (1) – offset buccally to cuspid to avoid area of premature
contact with lower first bicuspid.
• Canine – slight mesial rotation.
• Lateral – kept labially.
• Central – proper contact, midlines coincide with lower, level
incisal edges.

36. 1. Trace the nasion –basion
plane. Put a mark at point
CC.
2. Grow nasion 1mm/yr.
Treatment time – 2yrs.
3. Grow basion 1mm/yr for
2yrs.
www.indiandentalacademy.com
38. 1. Superimpose at basion along
basion – nasion plane. Rotate
up at nasion – open bite and
down to close the bite using
DC as fulcrum.
2. Trace condylar axis coronoid
process and condyle.
www.indiandentalacademy.com
39. 1. On condylar axis, make mark
1mm / yr. Down from point
DC.
2. Slide mark up to the basion –
nasion plane along the
condylar axis. Extend the
condylar axis to XI point,
locating a new XI point.
3. With the old and new XI point
coinciding trace corpus axis,
extending it 2mm / yr.
Forward of old PM point.
4. Draw posterior border of the
ramus and the lower border of
the mandible. www.indiandentalacademy.com
40. 1. Slide back along the corpus axis
superimpositioning at new and
old PM. Trace the symphysis
and draw in mandibular plane.
2. Construct facial plane from NA
to PO.
3. Construct facial axis from CC to
GN.
www.indiandentalacademy.com
41. Maxillary Growth Prediction
1. To locate the “new” maxilla
within the face, superimpose
at nasion along the facial
plane and divide the distance
between “original” and “new”
mentons into third by drawing
two marks
www.indiandentalacademy.com
42. 1. To outline the body of the
maxilla superimpose mark #1
on the original menton along
the facial plane. Trace the
palate, exception of point A.
www.indiandentalacademy.com
43. Maxillary Growth Prediction
Point A changes with various
mechanics
HG - -8mm
Class II – -3mm
Activator - -2mm
Torque - -1-2mm
Class III - +2-3mm
Facial mask - +2-4mm
1. Point A can be altered
distally with treatment. Place
according to orthopedic
problem and treatment
objective. For each mm of
distal movement, point A
will drop ½ mm
2. Construct new APO plane.www.indiandentalacademy.com
44. Occlusal Plane Position
1. Superimpose mark # 2 on original
menton and facial plane, then
parallel mandibular planes rotating
at menton. Construct occlusal
plane.
www.indiandentalacademy.com
45. Lower Incisor
1. Superimpose on corpus axis at PM.
Place a dot representing the tip of
the lower incisor in the ideal
position to the new occlusal plane,
which is 1mm above the occlusal
plane and 1mm ahead of APO plane.
2. Aligning over the original incisor
outline or using a template, draw in
the lower incisor in the final position
as required by arch length. Angle is
22 deg at =1mm to occlusal plane,
but the angle increases 2 deg with
each mm of forward compromise.
www.indiandentalacademy.com
46. Lower Molar
1. Without treatment the lower
molar will erupt directly upward
to the new occlusal plane. With
treatment 1mm of molar
movement equals 2mm of arch
length. Lower incisor moved
2mm in this case + 4mm of
leeway space. Therefore the
calculation allows us to move the
molar forward 4mm on each side.
2. Superimpose the lower molar on
the new occlusal plane at the
molar www.indiandentalacademy.com
47. Upper Molar
1. Trace the upper molar in good
class I position to the lower molar.
Use the old molar as template.
www.indiandentalacademy.com
48. Upper Incisor
Place upper incisor in good
overbite – overjet position =
2mm; interincisal angle 130
deg.
1. Trace the upper incisor in its
proper relationship aligning
over the original incisor
using it as a template.
www.indiandentalacademy.com
49. Soft Tissue – Nose
1. Superimpose at nasion along the
facial plane. Trace bridge of the
nose.
2. Superimpose at anterior nasal
spine (ANS) along the palatal
plane.
3. Move prediction “back” 1mm /
yr. Trace tip of nose fading into
bridge.
www.indiandentalacademy.com
50. Soft Tissue – Pt. A and Upper
Lip
1. Superimpose along the
facial plane at the occlusal
plane. Divide the horizontal
distance between the
“original” and “new” upper
incisor tips into thirds by
using two marks.
2. Point A remains the same,
superimpose new and old
bony point A and make a
mark at soft tissue Point A.
3. Keeping the occlusal planes
parallel, superimpose mark
# 1 on the tip of the original
incisor (slide forward 2/3).
4. Trace upper lip connecting
with point A. www.indiandentalacademy.com
51. Lower Lip, Point B, Soft Tissue
Chin
1. Superimpose interincisal points
keeping occlusal planes
parallel. Trace lower lip and
soft tissue B point. The soft
tissue below lower lip remains
in the same relation to point B
as in the original tracing. Soft
tissue point B drops down as
lower lip recontours.
www.indiandentalacademy.com
52. Completed V.T.O
1. Superimpose on the
symphysis and arrange the
soft tissue of the chin. It
should be evenly
distributed over the
symphysis.
