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.
Management of the developing occlusion lies firmly within the scope of pediatric dentistry, therefore protection of dental arch integrity and inter-arch relations in the premature loss of teeth can be guaranteed by placing space maintainers. Conventional appliances are used successfully as space maintainers, although they have some disadvantages.The need for at least two visits to delivery, therefore cannot be planned in patients under general anesthesia. Fabrication of conventional and loop requires an alginate impression and laboratory work.
Prefabricated band and loop devices have been introduced to dentistry in recent times. They can possibly overcome most of the previously mentioned limitations of conventional space maintainers. The prefabricated band and loop space maintainer is adjusted and applied in one visit and therefore can be planned in patients under general anesthesia. Other advantages include less time, more patient and parent satisfaction, and no laboratory work

| conventional space maintainer | Other | Conventional band and loops have been widely used with a high rate of success as the most practical way of space maintenance, as reported in numerous articles . Band and loop space maintainer is used to maintain space for successors of early lost primary molars. This is due to the ease and practicality of fabrication, adjustments and repairs of this space maintainer, as well as its ability to continue to function until the eruption of the permanent successor without interfering with their eruption The need for at least two visits to delivery, therefore cannot be planned in patients under general anesthesia. Fabrication of conventional and loop requires an alginate impression and laboratory work. |

| prefabricated space maintainer | Device | 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, |

Blinding will not be feasible neither for the operator nor the patient. As there are some differences in the clinical steps, the form of the appliances and number of needed visits.
Outcome assessor and Statistician will be blinded from the intervention and control not knowing which group represents which procedure.
