MOLAR UPRIGHTING

What is a frequent problem in adults?

Loss of posterior teeth - usually first perm molars

Correction of Molar Uprighting will depend on...

_______ and _____ of teeth lost

_____ at which this occurs

______ elapsed since the loss

______ relationship

______ of neighboring teeth

Position and number

Age

Time

Occlusal

Angulation

Biological problems assocaited with mesially tipped molar:

Poor _____ force stress distribution

Improper ______ of teeth in occlusion

______ in the dental arch

_________ of opposing teeth

chewing

interdigitation

Spacing

Over eruption

Restorative Problems Associated With Mesially Tipped Molar:

Excessive tooth structure _____ , _____ crown structure would have to be _____

Non-______ line of withdrawal of the fixed bridge

removal - too much - removed

Parallel

Restorative Problems Associated With Mesially Tipped Molar:

Poor ______ of the fixed crown retainer

Variable _____ size: Often the residual space between non-parallel abutments is only a _____ of a 'normal mesio-distal crown dimension

retention

pontic - portion

When to Upright a Molar: Decison depends on...

The length of the _______ space (>___mm of _____ movement (with space closure) in adults is extremely _____ )

The position of the ______ teeth

The _____ desired

The _______ desired

The ______ of the bone in the edentulous ridge area

edentulous - 5, - mesial difficult

opposing

occlusion

anchorage

contour

When to Upright?

0-10 degrees?

10-15 degrees?

15-50 degrees?

50+ degrees?

No need

Uprighting is okay but not essential

Upright indicatedd

May not be possible or feasible without surgical assistance

Uprighting of a tooth generally _____ the tooth, but it also tends to reduce the depth of the _______ that maybe present on the _____ surface of the tooth being uprighted

Extrudes

pseudo-pocket

mesial

After proper alignment and leveling is achieved, a single ______ sectional rectangular arch-wire is adapted to fit passively into the brackets on the anchor teeth and gabled at the _____ to exert an uprighting force on the molar

T-loop

"T" loop

When using a T loop to upright a molar...

When engaged into the molar bracket, the wire will thrustt he roots ____ while the crown tips _____

mesially

distally

When using a T loop to upright a molar... the distal end of the arch wire should be pulled ______ through the molar tube, opening the T-loop by ____-____ mm

distally

1 or 2

What are the two methods to upright molar? Which one increases space for pontic or implant?

Upright tooth by distal crown movement - creates space

Upright tooth by mesial root movement - reduces edentulous span space
