简要总结
compare 3D Printed versus CAD/CAM fabricated modified fixed appliance for rehabilitation of premature loss of anterior teeth in preschool children
详细描述
The study will be conducted as a clinical trial and it will be carried out at Pediatric Dentistry Department, Faculty of Dentistry, Tanta University. Forty preschool children from both genders aged from 3-5 years will be included in the study. The selected children will be divided into two groups.
Group I: Twenty children will receive 3D Printed modified fixed bridge. Group II: Twenty will receive CAD/CAM fabricated modified fixed bridge. Evaluation of both appliances will be carried out at baseline, 6 and 12 months

- •Premature loss of one to four maxillary primary incisors
- •At least 6 months remaining before the expected eruption of the permanent successor
- •Presence of sufficient healthy abutment teeth (primary canines)
- •Adequate oral hygiene (Plaque Index ≤1).
