Vertical Ridge Augmentation of the Anterior Maxilla

Vertical ridge augmentation presents one of the greatest challenges of bone regeneration in implant dentistry, primarily due to the difficulty of the surgical procedure and its potential complications. Patient selection, patient preparation for surgery, precise surgical techniques, and postoperative management are the key factors in reducing the rate of bone graft complications.

To predictably achieve successful bone augmentation angiogenesis, clot stability and space maintenance should be employed. The detailed surgical protocol of the different types of anterior maxillary defects including patients presenting with scarred periosteum and loss of vestibule will be discussed in detail.

In an attempt to achieve wound closure and hence graft stability, the buccal mucosa are often broadly released, and this often results in a severe apical translocation of the mucogingival line, loss of vestibule and keratinized mucosa (KM).

The protocol of the preservation of the regenerated ridge and soft tissue architecture will be discussed.

Utilizing these procedures may lessen the need of harvested autogenous bone and may generally lead to decreased morbidity and therefore increased patient comfort and satisfaction associated with these regenerative procedures.

At the conclusion of this lecture participants will have gained an understanding of:

  1. The biology of the incorporation of the composite bone graft
  2. The surgical principles of ridge augmentation surgery
  3. The types of anterior maxillary vertical defects
  4. Surgical principles of the reconstruction of the vestibule and keratinized tissue after ridge augmentation
  5. How to preserve the regenerated bone and recreated papillary architecture


Istvan Urban, DMD, MD

Dr. Urban received his DMD degree and subsequently his MD degree from Semmelweis University School of Medicine and Dentistry (Budapest, Hungary) in 1991 and 1996. He completed a full-time program in oral surgery at St. Istvan Hospital in Budapest, Hungary (1992-1996). He completed his internship program in Periodontics at UCLA. After he graduated from the Fellowship Program (1999-2000) in Implant Dentistry at Loma Linda University in Loma Linda, California, he was appointed assistant professor the following year.

Dr. Urban teaches implant dentistry in the graduate program at Loma Linda University. He is licensed in the state of California (USA) and has a private practice in Budapest, Hungary. Dr. Urban received his PhD degree in Periodontology in 2012 at the University of Szeged, Hungary. He is currently an honorary professor at the University of Szeged. Dr. Urban is a board member of the Osteology Foundation and has published scientific articles and textbook chapters on bone regeneration and soft tissue reconstructive surgery around dental implants. Recently, Dr. Urban has become an adjunct clinical associate professor at the Department of Periodontology and Oral Medicine at the University of Michigan. Dr. Urban is the author of the textbook titled Vertical and Horizontal Augmentation published by Quintessence.
