Rehabilitation of Edentulous Jaws with Full-Arch Fixed Implant-Supported Prostheses: An Approach with Short and Ultrashort Implants and Metal-Free Materials.

. Short implants represent a valid alternative to bone regeneration techniques. In addition, metal-free prosthetic materials have several advantages for predictable rehabilitation.

Speed bleaching: the importance of temporary filling with hermetic sealing.

The aim of this study was to demonstrate the influence of an adhesive temporary restoration on the effectiveness of the bleaching reaction, regardless of the concentration of the bleaching agent used. Every clinician involved in conservative dentistry understands the incompatibility between 'chemical bond' and 'oxygen.' This awareness often influences clinicians to decide on a temporary 'mechanical retention' filling that is unable to prevent the escape of oxygen ions, forcing the patient into more sessions and therefore raising the risk of complications.
