简要总结
This study evaluate Microbial growth on Bre-Flex versus PEEK denture base in Bilateral Maxillary bounded partial denture , half of patients will receive a framework with breflex denture base and the other half will receive a framework with PEEK denture base then evaluate the Candida growth
详细描述
Peek and Bre.flex are both new material that introduced to the market recently with great benefits like aesthetics and bio-compatibility but which material has less candida growth ? Bre.flex is a nylon-based thermoplastic material, composed of nylon polyamide 12 (polyamide).Nylon exhibits high physical strength, heat resistance and chemical resistance. It can be easily modified to increase stiffness and wear resistance. Nylon resin can be semi-translucent and provides excellent esthetics but it is a little more difficult to adjust and polish.
Despite of its highly esthetics features, Nylon still suffers from surface roughness that increase the colonization for candida but less than heat cured acrylic Recently, PEEK is introduced as a removable prosthesis material due to its high mechanical and biological properties but further clinical studies or systematic reviews focusing on the use of PEEK dentures are needed.
The patient will be treated in visits designated as follows:
Visit 1: Preoperative records, clinical, radiographic examination (panoramic and periapical x-rays for evaluation the crown-root ratio, the apical condition of the abutment and their alveolar bone support of abutment) and primary impression will be performed with irreversible hydro-colloid impression material (alginate), The impressions will be poured with type IV dental stone to obtain diagnostic casts.
Visit 2: Maxillary Face-bow will be recorded. The diagnostic casts will be mounted on semi adjustable articulator in centric occluding relation to evaluate the inter arch distance and occlusal plane.
