简要总结

This study aims to compare the clinical evaluation and patients' satisfaction of space maintainers produced by digital workflow using the 3D-printing method (3D-SMs) versus conventional band and loop space maintainers (C-SMs) produced by traditional methods.

入选标准

  • Lower first permanent molar in active state of eruption
  • Patient and parent showing cooperation and compliance.
  • Medically free children.
  • According to space analysis available space is less than or equal to needed space
  • Primary molar loss in the last 1 week due to caries, infection, and resorption (to eliminate possible space loss)
  • Caries free, non-restored buccal surfaces of the mandibular second primary molars and deciduous canines.

排除标准

  • Children with previous allergies to stainless steel.
  • There was less than one year left for the permanent tooth to erupt (to prevent possible abutment toot loss)
  • The patient's oral hygiene is not sufficient and has periodontal problems (to accurately assess the periodontal effects)

结局指标

主要结局

Survival rate

时间窗: 1 year

Decementation, debonding, solder breakage, loop breakage, band breakage, and abutment tooth fracture will be evaluated clinically for both space maintainers

次要结局

  • Gingival health of the abutment(0,6,12 months)
  • Plaque accumulation on the abutment tooth(0,6,12 months)
  • Patients' satisfaction about the impression technique(Immediately after the im- pression/scanning)
