Sialoperoxidase and myeloperoxidase are the two main peroxidase enzymes found in the oral cavity. Sialoperoxidase is present in salivary secretions and in the biofilms that line the oral surfaces, while myeloperoxidase is abundant in the dento‑gingival sulcus area. In the presence of hydrogen peroxide (HO), oral peroxidases catalyze the oxidation of the pseudohalide anion thiocyanate (SCN) to hypothiocyanite (OSCN), a strong oxidant that serves an antimicrobial role.

Introduction: Periodontal prosthodontic surgery plays a major role in the integration of aesthetic and functional prosthetic restorations, including in the anterior area. Indeed, any dento-gingival disharmony of volume or shape must be corrected beforehand, thus justify a plastic periodontal surgery.
Observation: This is a 20-year-old patient, who consulted for essentially aesthetic motive: the restoration of the fracture 11.

In cases of an immediate insertion and loading of implants after a traumatic loss of the patient's own dentition or due to an inevitable extraction of an anterior tooth, it is essential to provide the patient with an adequate provisional crown. A soft-tissue recession must be avoided, whether it is due to a compression of the peri-implant soft-tissue caused by an over-dimensioned restoration in the cervical collar of the provisional crown or to a too small dimensioned sulcus former. A simulation of the exact dimension of the lost tooth - especially on the cervical part of the new provisional restoration - is expected to preserve all relevant information and allows the design of a naturally looking emergence profile.
