Summary

Compare two band and loop space maintainers made from two tooth colored materials; Polyetherethherketone (PEEK) and monolithic Zirconia (BruxZir) as regards to: * Clinical performance of space maintainers in terms of frequency of debonding or fracture of the appliance and health of adjacent gingiva during a one-year follow up. * Wear of the opposing teeth.

Detailed description

After extraction of the mandibular first primary molars in both mandibular quadrants, impressions will be taken with intraoral scanner. Then, it will be sent to the CAD/CAM laboratory to construct functional band and loop space maintainers using PEEK and monolithic zirconia 'BruxZir' blocks with proper shades. After the fabrication of the space maintainers of both sides, they will be cemented with resin luting cement containing MDP monomer. Photographs will be taken after cementation for the space maintainers and the patient will be informed and educated about the oral hygiene measures. The parents will also be inquired to call if any discomfort, debonding or fracture of the appliances happens.
