title: Interrelations of soft and hard tissues for osseointegrated implants.
abstract: Success in using osseointegrated dental implants-optimal function, esthetics, and phonetics-requires selection of the treatment modality that is optimal for the patient, protection of tissue blood supply, and adherence to a plan based on a thorough analysis of all deviations from the normal anatomy. The options for correction of hard-tissue deficiencies are mechanical modification of the implants and reconstructive surgery. Mechanical approaches reduce the time needed for reconstruction but direct the occlusal forces in unnatural directions. Surgical reconstruction is preferable. Any bone graft must be precisely fitted to the recipient site to facilitate revascularization. Restoration of hard-tissue dimensions usually requires soft-tissue coverage and augmentation. There are two basic options: (1) flaps with or without inlay or onlay grafts and (2) controlled tissue expansion. An onlay graft can help restore soft-tissue height and width. Inlay grafts have greater vascularity than onlay grafts, and the color matching is better. Controlled tissue expansion creates "like" tissue without a secondary defect, and fewer tissue transfers are needed. However, the technique is difficult, and the patient must make multiple visits to the office. For implant placement to be successful, the patient's expectations must be understood, and the benefit-to-risk ratio should be extremely high.
