Overfibers

Hi-Rem Post

Hi-Rem posts are typically made from high-strength glass or quartz fibers embedded in a resin matrix. This combination yields excellent flexibility and strength, more closely matching the elastic modulus of natural dentin compared to metal posts.

Biomechanical Compatibility:
The elastic modulus of fiber posts like Hi-Rem is similar to that of dentin, which helps distribute occlusal forces more evenly. This reduces the risk of root fracture - a common complication with rigid metal posts.

Hi-Rem Endodontic Post, has the great advantage to be easily removable when it is necessary.

The central longitudinal axis of Hi-Rem Endodontic Post is made of soft polymer macro-fiber, placing in this position doesn’t affect the resistance of the post, because the stresses are minimal (neutral axis)

Conclusions

The effective management of periodontal-endodontic lesions hinges on a multidisciplinary approach that integrates periodontics, endodontics, and restorative dentistry. By understanding the complex interplay between the periodontium, pulp, and dental restorations, clinicians can achieve accurate diagnosis and tailor comprehensive treatment plans. This collaborative strategy not only addresses infection and inflammation effectively but also ensures the preservation of tooth structure and restoration of function and aesthetics, ultimately enhancing patient outcomes and promoting long-term oral health.
