Implant site development
Site development in the esthetic zone for ideal soft and hard tissue conditions
Stable and healthy soft tissue conditions are important for the longevity of implant restorations and crucial for their esthetic success especially in the anterior region. Tooth loss and subsequent bone changes may result in inadequate bone volume for placing implants. The buccal plate and the bundle bone are a tooth related structure, and will be lost after tooth loss, resulting in average almost 4 mm bone loss horizontally and 1.5 mm vertically. Placing an implant as single measure cannot avod this bone loss, as the implant will not have a Sharpey fibre system. Objectives for horizontal and vertical grafting comprise improved tissue contour and volume, optimizing the implant position in all planes and esthetic results, support the biological width and gingival stability. There are various techniques and protocols for soft and hard tissue regeneration and augmentation for implant site development, such as connective tissue grafts, bone block grafts or guided bone regenaration with membranes. Platfom shift implant and adequate concave abutment emergence profile design can further incresase the soft tissue volume.
