Biography

Mohammad Rayyan received his Bachelor Degree in Dental Science in the Faculty of Dentistry, Cairo University, Egypt in may 1989. In 1990, he was an Intern Operator and had an excellent grade in Emergency, Prosthetic, Crown and Bridge, Surgical, Operative and Endodontic rounds in the Faculty of Dentistry, Cairo University, Egypt. He got his Master Degree in Restorative Dentistry in 2002 and Doctorate Degree in Fixed Prosthodontics in 2009 in the same university. In 2014, he studied one year Implant Diploma in the Faculty of Dentistry at Beirut Arab University.

He worked throughout 24 years in various fields of dentistry including first assistant in operations under general anaesthesia for condylotomies and construction of immediate obturators following partial maxillectomy operations as well as standard surgery, removable and fixed prosthodontics procedures.

Successfully, he designed tools and devices to be used and operated on many different fields; dentistry (in both under and post-graduate periods), sand sorting, chemical mixing.

 

He created three inventions in prosthodontics; Smart post, Retrievable crown system and paralleling platform (ongoing patent acquisition) and assisted in the construction of the BAU Central Lab as well as the CAD CAM unit. He updated trained and examined students on CAD of different restorations and trained lab technicians to meet the requirements and quality to be suitable to the BAU. Gathered and designed specialized bur kits for BAU students.

  • BAU Advanced for Prosthodontic Bur kit.

  • BAU Temporary Appliance kit.

  • BAU Mini Kit I, BAU Mini Kit II and BAU Mini kit III.
