Background
: In implant dentistry, bone substitute materials and barrier membranes are used in different treatments including guided bone regeneration (GBR), socket preservation, alveolar ridge augmentation, maxillary
sinus elevation, and filling bony defects around the inserted dental implant. One of the most important factors
in prognosis of treatments using these materials is the growth of new blood vessels in applied areas. Present review was performed to evaluate the effect of the bone-grafting and barrier membrane materials on angiogenesis
events.
Material and Methods
: An electronic search was performed in PubMed, MEDLINE, and EMBASE databases via
OVID using the keywords mentioned in the PubMed and MeSH headings regarding the role of angiogenesis in
implant dentistry from January 2000-April 2014.
Results: Of the 5,622 articles identified in our initial search results, only 33 met the inclusion criteria set for this
review. Among bone substitute materials the autogenous bone-grafts, and among the barrier membranes the collagenous membranes, had the highest angiogenic potentials. Other bone-grafting materials or membranes were
mostly used with pro-angiogenic factors to enhance their angiogenic properties.
Conclusions: Angiogenesis is one of the key factors, which plays a critical role in success rate of GBR technique
and is seriously considered in manufacturing bone-grafting and barrier membrane materials. However, there is
still lack of clinical and
in-vivo
studies addressing the effect of angiogenesis in treatments using bone-grafting
and barrier membrane materials.
