Evaluation of Polyetheretherketone and Monolithic Zirconia as Esthetic Functional Space Maintainers in Children (A Randomized Clinical Trial)
Ain Shams University
20 participants
Jan 3, 2024
INTERVENTIONAL
Conditions
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.
Eligibility
Inclusion Criteria6
- Children requiring bilateral extraction of mandibular first primary molars or those with previously extracted molars no more than 6 months prior to intervention (11) .
- Existence of teeth on the mesial and distal side of edentulous area.
- Angle's Class I molar relationship and/or flush terminal/mesial step primary molar occlusion
- No periapical and/ or furcural pathological condition related to abutment teeth.
- Presence of tooth germ of the succeeding tooth (mandibular first premolars).
- Presence of more than 1 mm of bone overlying the successor tooth germ
Exclusion Criteria5
- Carious abutment teeth requiring pulp therapy.
- Carious abutment primary teeth requiring a full coverage restoration.
- Patients with history of bruxism or/and clenching.
- Patients with medical, intellectual or physical disabilities.
- Patients with abnormalities as posterior cross-bite, open bite, and deep bite
