Study Notes
Consequences of Premature Loss of Primary Teeth
- Crowding or impaction of teeth
- Midline shift
- Retrusion of the anterior segment
- Increased overbite
- Arch length inadequacy (2-4mm/quadrant)
Factors Affecting Space Maintainer Construction
- Time elapsed since loss of primary tooth
- Dental developmental age of the child
- Amount of bone covering the permanent successor
- Sequence of eruption
- Delayed eruption of permanent teeth
- Congenital absence of permanent teeth
- Degree of development of the permanent successor
Requirements of Space Maintainer
- Simple design
- Hygienic
- Durable and corrosion resistant
- Easily adjustable
- Reasonable in cost and time
- Prevent abnormal tooth movement
- Must not hamper normal growth pattern
Indications of Space Maintainers
- Tooth loss and space analysis indicates arch length adequacy/severe crowding
- Tooth loss and space analysis indicates a possible arch length inadequacy for teeth, there is malocclusion or abnormal habits
- Within 6 months of tooth loss
- Amount of bone covering more than 1mm
- Disorder in the sequence of eruption
- Delayed /altered eruption of permanent teeth
- Congenital absence of permanent tooth
Contraindications of Space Maintainers
- No alveolar bone over erupting tooth
- Significant arch discrepancy requiring orthodontic treatment
- Excess space
- Space closure desired for congenital absence of tooth
- High caries activity and poor oral hygiene
- Poor patient and parent cooperation
Classification of Space Maintainers
- Means of Retention: Removable, Fixed, Semi-Fixed
- Activity: Active (Semi-Fixed), Passive (All Others)
- Functionality: Functional (Partial, Complete & Spoon Denture), Non-Functional (All Others)
Space Maintainers for Primary Molar
-
Band and Loop Space Maintainer: Most common, unilateral fixed appliance - ideal for maintaining the space of a single tooth. Loop should be wide bucco-lingually, in close approximation to the ridge without impinging on soft tissue.
- Advantages: Easy to make, economic, hygienic, durable, corrosion resistant
- Disadvantages: Does not restore masticatory function, will not prevent the continuous eruption of the opposing teeth
-
Crown and Loop Space Maintainer: Indicated if the posterior abutment tooth has had extensive caries and requires pulp therapy - requires preparation of the abutment tooth for the stainless steel crown and then the loop is soldered to the crown.
- Disadvantages: Adjustment of the loop is difficult, adapt a band and loop over a cemented crown
- Passive Lingual Arch: Bilateral fixed space maintainer indicated for multiple tooth losses in the mandibular arch, lower permanent incisors should be erupted - bands adapted to first permanent molars, wire closely adapted to the cingulum areas of the permanent incisors.
