Oral and Maxillofacial Surgery

Professor Dr. Dr. Nils-Claudius Gellrich, Director of the Department of Oral and Maxillofacial Surgery

Professor Gellrich, MD, DMD, is an internationally known specialist in oral and maxillofacial surgery.
As one of the pioneers in this field, he introduced computer assisted planning and intraoperative navigation into the clinical routine of oral and maxillofacial surgery. 

Professor Gellrich has been chair of the Department of Oral and Maxillofacial Surgery at the Hannover Medical School since 2004. He and his team are trend-setters in integrated quality management of dental implant treatment, which will become standard both in implant dentistry and in 3D planning to optimize the treatment of complex facial deformities.

Professor Gellrich has received numerous awards in recognition of his work. He is a member of many national and international scientific dental and medical societies and is on the advisory board of the medical services of the German armed forces.

Clinical Profile

The clinical spectrum of the Department of Oral and Maxillofacial Surgery at the Hannover Medical School ranges from preimplantological bone augmentation of atrophic jaws by using computer-assisted planning to the treatment of all benign and malignant tumors of the maxillofacial region as well as congenital and acquired deformities of soft and hard tissues.

The Department is particularly renowned for augmentative preprosthetic surgery, orbital and skull base surgery and for its outstanding expertise in 3D planning and orthognathic surgery.
For many years, one of the major centers for the interdisciplinary treatment of patients with cleft lip and palate has been established at Hannover Medical School, where oral and maxillofacial surgeons collaborate with specialists in phoniatrics, orthodontics, otorhino-laryngology, pediatrics and radiology.

The Department of Oral and Maxillofacial Surgery is a world leader in computer assisted surgery for primary and secondary reconstruction of the facial skeleton.
Among the specialties of the Department are innovative minimally invasive techniques such as endoscopically assisted fracture for the repair and extraction of salivary gland calculi.

Clinical profile of Professor Gellrich and his team:

  • Advanced dental implantology
  • Minimally invasive preimplantological bone augmentation
  • 3D-based orthognatic surgery
  • Cleft lip and palate treatment
  • Oral and maxillofacial tumor treatment and reconstruction
  • Computer-assisted planning and surgery including intraoperative navigation for reconstruction of complex facial deformities

Professor Gellrich and his clinical team of more than 20 physicians and 50 nurses provide superior expertise in all aspects of oral and maxillofacial surgery. As a university clinic, the Department‘s technical facilities are state-of-the-art.
The Department of Oral and Maxillofacial Surgery is also a DIN EN ISO 9001-2000 certified institution.

Scientific Profile

Professor Gellrich and his team of more than 20 coworkers address various problems of modern oral and maxillofacial surgery.
Research is focussed on the development of interactive computer-assisted planning and surgery using photorealistic imaging, optimized treatment of oral and maxillofacial malignancies, and tissue engineering of bone.
Neoadjuvant strategies for the treatment of advanced oral squamous cell carcinomas are currently being evaluated in a multicenter phase III study.

Tissue engineering research is funded by grants from the German Research Foundation (DFG).
Numerous industry collaborations ensure further development of intraoperative navigation and dental implant systems.

Professor Gellrich and his team have developed an unique, minimally invasive approach to bony reconstructions prior to dental implant insertion.
