| Abstract: | The popularity of osseointegration for the replacement of anterior teeth has placed an increased demand on the preservation of normal gingival anatomy. This has led to the development of a variety of soft-tissue and bone-augmentation techniques that either prevent tissue collapse or restore previously damaged areas of the alveolus. With bone grafts, barrier membranes, and autogenous connective-tissue grafts used in combination with each other or separately, lost structures can be reconstructed into a normal configuration for optimum esthetic restorations. |
