Space maintainer
Indication of space maintainer
Space shows signs of closing
Make future ortho treatment less complicated
Treatment of malocclusion is not indicated
Space for permanent tooth should be mainyained for 2 years or longer
Avoid supraeruption
Improve mastication and restore dental health
Contraindication of space maintainer
Succedaneous tooth will erupt soon
1/3 of roog of seccedaneous tooth is calcified
Space is greater than the size of permanet tooth
Space shows no sign of closing
Succedaneous tooth is absent

BAND AND LOOP SPACE MAINTAINERS
posterior segments when a single tooth is lost.
BAND AND LOOP SPACE MAINTAINER
posterior segments when a single tooth is lost.
BAND AND LOOP SPACE MAINTAINERS
Preserving the space created by the premature loss of a
single primary molar.
BAND AND LOOP SPACE MAINTAINERS
Bilateral loss of single primary molar before eruption of
permanent incisors.
BAND AND LOOP SPACE MAINTAINERS
When the 2nd molar is lost after the eruption of the 1st
permanent molar.
BAND AND LOOP SPACE MAINTAINERS
Indication of band and loop space maintainer
Preserving the space created by the premature loss of a single primary molar.
Bilateral loss of single primary molar before eruption of permanent incisors.
When the 2nd molar is lost after the eruption of the 1st permanent molar.
Contraindication of band and loop space maintainer
Long space
Space is loss
Severe malocclusion
Mobile tooth abutment
Advantages of band and loop space maintainer
Construction is easy and faster
Few appointments by patient
Many modifications are possible
