NCT06558812

Brief 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.

  • • Cost effectiveness

    through study completion , an average of 9 month

Study Arms (2)

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.

Device: conventional space maintainer

prefabricated space maintainer

OTHER

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

Device: prefabricated space maintainer

Interventions

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,

Also known as: chair side space maintainer
prefabricated 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 .

Eligibility Criteria

Age4 Years - 6 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Clinical criteria Medically free children.
  • Patient and parent showing cooperation and compliance.
  • Patients having mandibular first deciduous molar indicated for extraction due to extensive coronal caries beyond possible repair, root caries and/or failed pulp therapy.
  • Freshly extracted single molars unilaterally or bilaterally
  • Unilateral or bilateral loss of primary molars before or after the eruption of the first permanent molar
  • Caries free or restored the mandibular second primary molars and deciduous canines in the side of the extraction maintained throughout the entire follow-up period.
  • Radiographic criteria
  • Presence of succedaneous tooth bud.
  • Presence of at least 1 mm bone overlying the succedaneous tooth germ
  • /3 to less than 2/3 of the root of the permanent successor is formed to the prematurely lost primary molars.

You may not qualify if:

  • Children with any parafunctional habits.
  • Children with previous allergies to stainless steel.
  • Permanent successors with 2/3 of its roots formed and space analysis does not indicate the fabrication of space maintainer.
