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.
Study summary
Primary dentition is the most suitable space maintainer for permanent teeth. However, as infants often lose their primary teeth too soon, using a space maintainer is the most efficient, long-lasting, and economical way to prevent malocclusions and function impairment in the future. Regarding personalized appliances, space maintainers in digital pediatric dentistry have made significant progress. Digital technology decreases the manual manufacturing stages that take a long time and increases the reliability and durability of digital fabrication procedures.

Primary outcome measure(s)
clinical evaluation — three months the clinical performance of the partial denture space maintainers in the recall visits will be to assess: the Fracture of the space maintainer, and Lost or missing
gingival health — three months using a Williams periodontal probe, gingival index will be evaluated according to the following criteria:
* 0: Healthy gingiva.
* 1: There is mild inflammation, discoloration and edema, no bleeding on probing.
* 2: Moderate inflammation, marked redness, edema, and bleeding on probing.
* 3: Severe inflammation, prominent redness and edema, ulceration, spontaneous bleeding tendency.
plaque index — three months using a Williams periodontal probe, the plaque index will be assessed using the Silness-Loe plaque index: 0: Absence of microbial plaque, 1: Thin film of microbial plaque along the free gingival margin, 2: Moderate accumulation with plaque in the sulcus, 3: Large amount of plaque in the sulcus or pocket along the free gingiva margin.
