Purpose. To present a computer-assisted-design/computer-assisted-manufacturing (CAD/CAM) technique for the design, fabrication, and clinical application of custom-made synthetic scaffolds, for alveolar ridge augmentation. Methods. The CAD/CAM procedure consisted of (1) virtual planning/design of the custom-made scaffold; (2) milling of the scaffold into the exact size/shape from a preformed syn...

PURPOSE This study aimed to develop a classification of edentulous jaws for use as a diagnostic tool during implant-prosthodontic treatment planning. MATERIALS AND METHODS The morphology of 200 fully edentulous alveolar ridges (100 maxillae, 100 mandibles) was assessed with cone beam computed tomography. Generic implants (length: 8 mm; diameter: 4.1 mm) were used. To develop the classificatio...

BACKGROUND In the case of localized ridge atrophy, a ridge augmentation procedure, with the use of bone substitutes and barrier membranes, may then be necessary. PURPOSE The aim of the present study was a clinical, histological, and immunohistochemical evaluation of an equine spongy bone in alveolar ridge augmentation procedures. MATERIALS AND METHODS Five patients showing horizontal mandib...

PURPOSE The main purpose of the present clinical study was to compare architectural metric parameters using micro-computed tomography (μ-CT) between sites grafted with blocks harvested from the intramembranous origin calvarium and endochondral origin iliac crest for horizontal bone augmentation in the maxilla. The second aim was to compare primary stability of implants placed in both types of b...

OBJECTIVE The aging nose presents as a drooping nasal tip secondary to atrophy of the underlying bony support with a relatively prominent dorsal hump. We hypothesized that low nasal tip projection in the Asian nose may be secondary to the retropositioned anterior nasal spine (ANS) as well. Therefore, we investigated how filler injection between the medial crura and the retropositioned ANS affec...

This article describes a technique to predictably reconstruct both horizontal and vertical bony defects with one graft, the autogenous J-graft. Bone harvested from the ramus is contoured in three dimensions resulting in both a horizontal and a vertical component. When there is inadequate soft tissue due to the increase in bone volume at time of augmentation, the bone graft is combined with a pe...
