Evaluation of the Success Rate of Prefabricated Versus Conventional Band and Loop Space Maintainers in Children With Prematurely Lost First Primary Molars
Sponsor: Cairo University
Summary
To assess the clinical efficacy of prefabricated space maintainers compared to conventional ones, focusing on preserving the integrity of each component of bands and loops, avoidance of soft tissue impingement as well as preservation of arch dimensions.

Interventions
prefabricated space maintainer
i. Prefabricated band will be selected for the abutment tooth by measuring the mesiodistal diameter of the abutment tooth with a caliper and will be adjusted with the internal diameter of the prefabricated band. ii. The loop will be selected based on the available mesiodistal space and buccolingual width of the abutment tooth, excessive length with be cut by cutting plier and will then place inside the band's tube by using a HOWE pliers. iii. Cotton roll isolation will use, then will be cemented with glass ionomer,
conventional space maintainer
i. A full arch Impressions will be taken with alginate material. ii. Impressions will be poured up using dental stone within 30 min of the impression taking. iii. The children will be given an appointment for space maintainer insertion. iv. In the second visit , Cotton roll isolation will use, cementation will be performed with glass ionomer .
