Laith A Hussein, Thair A L Hassan
The posterior maxilla is challenged with postextraction alveolar bone resorption and pneumatization drive of the Schneiderian membrane that reduces the subantral distance. To overcome such anatomic obstacle a sinus augmentation procedure was introduced either via lateral or crestal approach depending on residual ridge height. The current study evaluated oxidized regenerated cellulose (ORC) as a grafting material versus osteon II by measuring bone gain and graft density, 24 weeks postoperatively. Twenty consecutive patients (24 cases) aged from 20 to 65 years were considered eligible after clinical and radiographic evaluation...

Michael S Block
The narrow ridge in the anterior maxilla often requires horizontal augmentation for ideal implant placement. This article reviews the historical use of a closed, tunnel approach to augment deficient alveolar ridges and describes its application for augmentation of the narrow ridge in the anterior maxilla. The use of a tunnel approach through a vertical incision in the unattached mucosa provides access to the ridge while maintaining crestal attachments without displacement of the crestal attached gingiva. This approach is atraumatic and provides excellent access for placement of graft material for ridge augmentation...

Autogenous bone remains the gold standard for augmentation of the alveolar ridge in congenital hypodontia and appreciable post-traumatic deformity. This generally reflects the volume of material required for such defects and the osteogenic potential of the grafts. Morbidity at the donor site and success rates may lead to autogenous grafts being superseded by xenografts or alloplastic materials in the future, but we know of little evidence to confirm this. All patients having augmentation of the alveolar ridge or sinus lift to enable subsequent placement of implants between 01 January 2009 and 31 December 2016 were identified from a prospectively-gathered database held at the Queen Elizabeth Hospital, Birmingham...

The aim of this randomised controlled clinical trial was to assess the early efficacy of bone morphogenetic protein-2 with hydroxyapatite granules (BMP-2/hydroxyapatite) on augmentation of the alveolar ridge, by comparing changes in volume with those associated with the use of an inorganic bovine-derived xenograft (BDX). We studied 20 patients who were divided into two groups using a table of random numbers, and BMP-2/hydroxyapatite and BDX were applied accordingly. Computed tomographic (CT) images and panoramic radiographs were obtained immediately after operation and four months later...

Regenerative therapies are commonly needed prior to implant placement in the posterior maxilla following tooth extraction. The aim of this study was to investigate the anatomical features of the atrophic posterior maxilla that might affect surgical approach selection and technique and risk of intra- and postoperative complications. Cone beam computed tomography files were screened to identify pristine atrophic maxillary ridges in need of bone augmentation (ridge height < 10 mm). Ridge height and width and lateral wall thickness (LWT) were measured at different levels, and palatonasal recess and lateral wall morphology were calculated...

This study investigated the dimensional change and microstructure of intraoral bone block grafts covered with platelet-rich fibrin (PRF) and a barrier membrane in ridge augmentation. Seven patients were included, with 18 implant sites (10 ramus and 8 symphysis). The average final ridge width gains in the ramus from cast-based measurement (3.86 ± 0.87 mm) and cone beam computed tomography measurements (3.63 ± 1.38 mm) were not different from the symphysis (3.36 ± 2.26 mm and 3.44 ± 1.52 mm, respectively)...

Guided bone regeneration has become more predictable due to advances in material sciences. Nevertheless, vertical ridge augmentation (VRA) remains a potential challenge due to the complexity of soft tissue management. This becomes more complicated in the posterior atrophic mandible due to limited access and poorer blood supply. As such, a number of critical elements must be taken into consideration in treatment planning. Anatomical structures potentially jeopardize intraoperative adverse events such as bleeding or neurosensory disturbances...
