SIMULTANEOUS AND STAGED RIDGE AUGMENTATION – SELECTION OF PROTOCOLS AND BIOMATERIALS
Appropriate and successful alveolar ridge augmentation creates optimal conditions for prosthetically driven implant placement and long term stability of achieved therapeutical results.
Simultaneous augmentation comprises shortened treatment time, lower morbidity and reduced treatment costs, compared to staged augmentation procedures. However, the predictability of bone regeneration is reduced with simultaneous approach. Therefore, clinicians have to consider numerous factors when deciding which protocol is optimal for given clinical situation.
Among those factors, shape of the defect is of critical importance. Defects within the bone envelope, with more bony walls, are much easier to regenerate, compared to the unconfined defects outside of the contours of the alveolar ridge. In particular, augmentation of combined horizontal and vertical defects, or strictly vertical defects of the alveolar ridge is much less predictable. Other factors to consider include esthetic risk assessment and systemic factors, such as metabolic and drugs-related disturbances of the wound healing.
Apart from decision whether to perform simultaneous or staged augmentation, appropriate selection of regenerative materials is of the utmost importance. While autologous bone comprises high regenerative potential, stimulating osteogenesis, it is also prone to significant resorption, reducing the amount of newly formed bone. In contrast to this, xenografts demonstrate high dimensional stability but also tend to leave significant amounts of unresorbed graft particles at the augmentation site, which reduces formation of new vital bone.
Finaly, successful augmentation requires stabilization of the graft and good contouring of the alveolar ridge. This can be achieved either by usage of block grafts with fixation devices or by application of non-resorbable titanium reinforced membranes or titanium mesh.
Key words: dental implant, ridge augmentation, bone augmentation
Professor Miroslav Andric, DMD, PhD
Updated on December 22nd, 2024.
Dr Miroslav Andric earned his degree from the School of Dental Medicine, University of Belgrade, in 1997. In 2002, he completed the Residency Program in Oral Surgery at University of Belgrade.
He has completed postgraduate studies in Oral Surgery at the University of Belgrade and in 2006 he reached the title Master of Science in Oral Surgery. In 2012 he completed his PhD thesis at the University of Belgrade.
Current position: Professor of Oral Surgery, Anesthesiology and Implantology, School of Dental Medicine, University of Belgrade.
Professor Andric is involved in courses of Oral surgery, Anesthesiology and Implantology for undergraduate students and in courses of Biomedical publishing and Introduction to biomedical research for doctoral students.
He took part in CME programs at University of Zurich, Zentrum für Zahn-, Mund- und Kieferheilkund and University of Tubingen.
Dr Miroslav Andric has published numerous articles in leading scientific journals indexed in Science Citation Index and presented numerous lectures in Serbian and international scientific meetings in fields of oral surgery and implantology. His primary research focus is on oral and maxillofacial pathology and microbiology and regenerative procedures and materials.
He has been serving as a Secretary of Section of Oral Surgery and Section of Oral Implantology of Serbian Medical Association.
He is an ITI Fellow since 2010 and registered ITI speaker, also actively participating in the development of the ITI Academy, as a Senior Editor.
He is actively involved in the work of ITI Study Club Belgrade, currently serving as a director of ITI study club Belgrade 2, and in postgraduate and residency programs in Oral Surgery and Implantology at University of Belgrade.
Oral implantology represents a significant portion of his clinical work. He performs both surgical and prosthodontic implant procedures, including complex regenerative surgery. He also serves as a lecturer for courses in advanced implant and augmentation surgery.
