Key points

The team at 47VH in Nice brings together dental surgeons trained in implantology, periodontology, and oral surgery, with an organization focused on implant treatments, periodontal diseases, and complex situations. Each patient is referred to the most appropriate practitioner according to the nature of the treatment: specialist consultation, implant surgery, non-surgical periodontal treatment, or maintenance.

The 47VH practice brings together a team of dental surgeons whose activity is exclusively focused on periodontology, implantology, and oral surgery, trained at recognized French and international universities.

Doctors Sylvain Leymarie and Sylvain Mouraret conduct the initial consultations, periodontal re‑evaluations, and the surgical periodontal phases and implants.

Dr Sylvain Leymarie

Dental surgeon

Sylvain Leymarie obtained a Doctorate in Dental Surgery, then completed a postgraduate program in Periodontology and Implant Dentistry at the University of Paris VII.

He then completed a teaching assistant position at the University of Paris VII, where he taught advanced treatments in Periodontology and Implantology.

Dr. Leymarie now practices privately, exclusively in Periodontology and Implantology, while maintaining a role as a lecturer so as to provide his patients with the most current techniques.

He regularly gives lectures in France and abroad and has published numerous international scientific articles.

His training enables him to treat gum diseases (tooth loosening) , as well asimplantology and oral surgery, incuding bone reconstruction.
