Vertical And Horizontal Ridge Augmentation Of A Severely Resorbed Ridge In The Anterior Maxilla

Introduction: Achieving esthetically pleasing therapeutic outcomes when rehabilitating a deficient anterior maxilla with dental implants can be very challenging. This case report presents the use of platelet-rich plasma (PRP) and guided bone regeneration (GBR) in combination with autogenous block grafts in the three-dimensional bone augmentation of a severely deficient anterior maxillary ridge.Case Presentation: A patient with a missing maxillary left lateral incisor received a cone-beam computed tomography scan, which revealed a horizontally and vertically deficient residual ridge. Horizontally, the residual had no buccal plate and a thin palatal plate. Vertically, the defect was 14.5 mm as measured from the cemento-enamel junction of adjacent teeth to the most apical point. Both buccal and palatal sites were treated with autogenous ramus block grafts, GBR, and PRP in an attempt to gain adequate ridge height and width for future implant placement. The surgical site was reentered 6 to 9 months after the bone augmentation procedure, and a dental implant, with no additional bone grafting, was placed with adequate primary implant stability. As a result of the successful gain in bone width and height through the augmentation procedure, an esthetic outcome was achieved with the implant-supported restoration. In addition, no signs of inflammation, peri-implant bone loss, or implant mobility were observed.Conclusion: Vertical and horizontal bone augmentation can be successfully performed to gain bone height and width that is essential for ideal implant positioning and esthetic outcomes.
