Genioplasty
Genioplasty is a precise aesthetic and functional procedure designed to
refine the shape, projection and overall balance of the chin.
A chin that is small, recessed or asymmetric can disrupt facial
proportions and affect the harmony between the lower jaw, lips and nose.
Through controlled advancement, setback, lowering or vertical augmentation,
the chin can be reshaped to create a more balanced profile and natural facial
symmetry.
Surgeons use digital 3D planning and highly accurate surgical techniques to achieve
stable contours, functional improvement and predictable, natural-looking results.
Bone Grafting
Adequate bone volume is essential for stable implant placement. When
bone has been lost due to inflammation, trauma or long-term tooth loss,
it can be reconstructed with targeted augmentation techniques.
Depending on the clinical situation, bone grafts, block grafts, internal
or external sinus lifts may be used. With precise planning, 3D imaging
and minimally invasive approaches, the bone can be safely regenerated to
provide a strong foundation for high-quality dental implants.
The goal is to achieve functional stability, natural aesthetic
reconstruction, and long-term success of the implant-supported restoration.

Sven Nyman and Christoph Dahlin
Sven Nyman and Christoph Dahlin from Sweden laid the biological foundations for guided bone regeneration, which is now used in combination with autologous bone. Dahlin et al. published the fundamental work on bone healing through guided tissue regeneration as early as 1988, and Nyman described the principle of guided tissue regeneration in 1991.

Matteo Chiapasco
Matteo Chiapasco from Italy is one of the most prolific researchers in this field. Among other publications, Chiapasco compared autologous onlay bone grafts with alveolar distraction osteogenesis in vertically deficient alveolar ridges, achieving 100% implant survival rates with a follow-up of up to four years. He is considered an expert in complex vertical augmentations.
