Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
conventional acrylic partial denture space maintainer
an elastomeric impression will be done to produce a plaster cast then a conventional acrylic partial space maintainer will be fabricated and delivered for the child patient.
No interventions assigned to this group
3-D printed partial denture space maintainer
A 3-D intraoral scanner will be used to produce digital models. STL file will be used to design a 3-D printed partial denture space maintainer which will be delivered to the child patient.

space maintainer
3-D printed partial denture space maintainer will designed for each child patient who has premature loss of primary teeth after doing intraoral scanning
space maintainer
a conventional impression will be done for a child patient with premature loss of his primary teeth, then a plaster model will gained. A conventional acrylic partial denture will be designed and delivered to the patient.
