Abstract

As a sequence of post-extraction ridge resorption and secondary pneumatization of the maxillary sinus, the height of available bone is significantly reduced in posterior maxilla. Therefore, for the correct and safe placement of implants in atrophic maxilla, site development procedure such as vertical ridge augmentation is recommended. The aim of the case report was to evaluate the long-term clinical and radiographic outcomes of implants placed into bone regenerated by vertical ridge augmentation using non-resorbable membrane. Three patients were selected from those seeking implant rehabilitation and presenting an insufficient corono-apical height of available bone due to severe ridge atrophy and post-extraction. The vertical ridge augmentation was performed using bone substitute and non-resorbable membrane, and staged implant placement was performed. The crestal bone resorption was measured at the time of surgery and follow up period with the distance from the CEJ to alveolar bone crest on panoramic view. In all cases, sufficient bone regenerated through vertical augmentation with non-resorbable membrane was observed. There is no noticeable decrease in vertical bone level between the baseline and follow-up periods. It is concluded that vertical augmentation with non-resorbable membrane at the severe atrophic ridge offer safe and predictable long-term results.
