简要总结
Different types of post and core have been used for several years for restoring anterior endodontically treated teeth, but their preparations involve various risks such as: root perforation, root weakness and tooth fracture. The introduction of adhesive systems and conservative restorations, make it possible to reconstruct damaged anterior endodontically treated teeth with conservative restoration as endocrowns. The hypothesis of this trial is that E-max CAD endocrowns will show comparably equal clinical performance if compared to E-max CAD crowns retained with fiber reinforced composite post and core system when treating anterior endodontically treated teeth..
详细描述
This trial will be conducted on patients from the out patient clinic in the fixed prosthodontics clinic, Faculty of Oral and Dental Medicine, Cairo University.
- Adherence session will take place in the presence of the patients in the initial visit. This include that the patients will be informed by Abou El-Enein Y about the study steps and maintenance of oral hygiene instructions. Participant will be asked by Abou El-Enein Y if they have any problem like pain.
- Motivation and enforcing the maintenance of oral hygiene measures by Abou El-Enein Y.
The visits will be designed as follow:
- st visit: (Y.A) will call participants before tooth preparation procedure for preoperative records, face to face adherence reminder session, clinical examination, radiograohic examination, pre-operative photographing, Impression taking for study cast analysis and waxing up. Each participant will be asked to sign consent form written in patient native language.
2nd visit: Tooth preparation for either e-max crown retained with fiber reinforced composie post or e-max endocrown, secondary impression and temporarization.

研究组 & 干预措施
E-max CAD crowns retained with Fiber Reinforced Composite Post
The modulus of elasticity of FRC post is (18-22 GPa) resembling that of dentin. Ideally the remaining tooth, the fiber post and the composite cement create a "monoblock" in which the loads are uniformly dissipated, ensuring a behavior similar to healthy teeth with a lower risk of root fracture. Using lithium disilicate e.max restorations is documented in literature as a successful restoration.

E-max CAD Endocrowns
Endocrowns have several advantages over conventional crowns like adequate function and esthetic with less chair time reduced number of interfaces in the restorative system. Stress concentration is less because of the reduction in the nonhomogenous material present. The preparation design is conservative compared to the traditional crown. Supragingival margin prevents interferences with periodontal tissues so involvement of the biological width is minimal. The application and polymerization of resins is also better controlled. Emax ceramic material have a high mechanical strength and are capable of being acid etched, with the adhesive capacity of adhesive systems and resinous cements, made it possible to restore endodontically treated teeth, without cores and intraradicular posts.
