Management of space
maintenance problems in
children
BY:
Mennat Allah Alkaram
Under supervision of:
Professor Nagwa Khattab
WHAT’S SPACE
MAINTAINERS ?
Appliance used to
maintain space or
regain minor
space loss, so as
to guide
unerrupted tooth
into a proper
position in the arch
Premature Loss Of Primary Teeth: Why?
Caries
Trauma
Ectopic eruption
Abnormal root resorption
Effect of pre-mature loss?
 Undesirable tooth movements of
primary and or permanent teeth
including loss of arch length.
 Teeth try to retain contact, and when,
adjacent contact is missing they
usually drift and opposing tooth
supraerupts.
 Arch length deficiency can produce
or increase the severity of
malocclusions with crowding,
rotations, unfavorable molar
relationship & occlusal plane
discrepancies.
Any extraction in children
should followed by S.M !!!!
1.Time elapsed since
loss
it usually takes place during
the first 6 months after the
extraction.
01
02
3. Amount of bone
covering the
unerupted tooth
03
2. Dental age of the
patient
The chronologic VS
the developmental
age.
4. sequence of
eruption of teeth. 04
05
6. degree of
development of
permeant successor
06
5.congenital
absence of
permeant successor
Methods utilized for
arch analysis
A. Probability charts (moyer’s
analysis):
Using probability chart to predict M-D width of
canines and premolars.
Can be used for both arches.
Procedure:
1. Measure the M_D width of lower incisors.
2. Using the probability chart and based on
the sum. Of width of permanent incisors ,
determine the predicted sum. Of
unerrupted 3,4,5 ( required space)
3. Measure the (available space) on the
cast from D surface of 2 till M of 6
4. Estimate the adequacy of space.
Methods utilized for
arch analysis
B. Nance analysis:
Using IOPA , Nance was able to detect the
required
arch width.
Procedure:
(Required space) compared to (Available space
– leeway space)
Where:
Required space : sum. Of M-D width of anterior +
M-D width of 3,4,5 obtained by IOPA.
Available space : arch length from M surface of 6
to M surface of corresponding 6
Leeway space : 1.8 mm in upper , 3.4 mm in

1- A 6 years old child came to your clinic and had to
extract his right lower 1st deciduous molar
* What is the type of space maintainer would you
use?
2- A 8 years old child came to your clinic after extracting his lower 1st
deciduous molar
* What is the type of space maintainer would you use ?
3- A 7 years old child came to your clinic and you had to
extract both 1st primary molars
*what types of space maintainers would you use for him ?
4- A 7 year old child came to your clinic and you had to
extract multiple primary molars
*what type of space maintainer would you use for him ?
5- A 8 year old child came to your clinic and he
has no D and E ,
what is the possible space maintainer you could
use ?
6- A 5 year old child came to your clinic and you
had to extract his E s ,what would you do ?
7- 8 year old child came to your clinic and you had to
extract both upper 1st primary molars
*what type of space maintainer would you use for him ?
8- A 9 year old child came to your clinic and you had to
extract both upper 2nd primary molars
*what type of space maintainer would you use for him ?
And its classification?
9- A child came to your clinic having multiple premature
loss in his teeth.
What’s your diagnosis ?
What’s your management ?
10- Patient with ECC needed extraction of primary incisors
, what are possible types of SM that could be used ?
