The success of pre prosthetic surgical preparation depends on careful evaluation and treatment planning. In general, bony abnormalities should be managed first. Associated soft tissue correction is often delayed until bone augmentation and contouring is completed. Simultaneous bony augmentation is attempted, it is aimed at improving contour rather than creating significant augmentation in alveolar height or width. Final prosthesis design and goals of long-term function, esthetic quality, and tissue maintenance must be considered during all phases of treatment When the principles of case selection and treatment outlined previously are followed, excellent results and patient satisfaction can be expected.
