Purpose: The purpose of this study was to provide a comparative evaluation of the survival times and failure rates of different types of fixed space maintainers (SMs).
Methods: A total of 30 4- to 10-year-olds were selected for the study. Children were divided into 3 groups, according to type of SM, namely: band and loop (B&L), direct bonded (DB), and fiber-reinforced composite (FRC). Patients were recalled once every 3 months for clinical evaluation for 1 year or until failure. The survival times of SMs were estimated by means of the Kaplan-Meier method, and confounding factors were investigated using Cox regression analysis.
Results: Mean survival time was highest for B&L SMs (11.20 months), followed by DB SMs (9.20 months) and FRC SMs (6.70 months). There were statistically significant differences noted between types of SMs (log rank=11.99; P=.002). The Cox proportional hazards model revealed that age, sex, dental arch, and side of the jaw were not significantly correlated with "success of SMs" (P>.05).
Conclusions: Band and loop fixed space maintainers showed superior performance in terms of both survival time and success rates versus direct bonded and fiber-reinforced composite space maintainers.

Background: The best space maintainer in both primary and mixed dentition is the primary tooth itself. This is not only because of the clinical crown but also due to the presence of the roots and periodontium that guide the eruption of the permanent tooth. Although over the years many materials have been tried for obturation of pulpectomized primary teeth, no material has been found to fulfill all requirements.

Unlabelled: Preserving deciduous teeth till their natural exfoliation is important to maintain arch length in different dentition periods. Premature loss of primary teeth may cause discrepancy in arch length due to drifting of teeth and supraeruption of the opposite teeth, thereby hindering the development of a harmonious, functionally and esthetically acceptable dentition. This article describes the fabrication and clinical application of a modified functional distal shoe appliance used due to pathological obliteration of the primary/deciduous mandibular second molar prior to the eruption of the permanent mandibular first molar.

Premature loss of primary teeth can lead to crowding, rotation, ectopic eruption and impaction of permanent teeth. All of these issues can be reduced or avoided through proper preventive and interceptive orthodontic procedures including the use of space maintainers and space regainers, many of which require two visits and a laboratory phase for fabrication. The 'Junaidi space regainer' is an attempt to make the space regaining procedure simpler and easier.
