Own Bone and Own Tissue Seal


A surgical procedure with the patient’s own bone and tissue is the gold standard, as it does not trigger rejection reactions and integrates best. Surgeons working with own bone and tissue frequently use techniques such as the shell technique according to Khoury and employ own platelet-rich fibrin (PRF) as membranes and clots. Evidence based research fullfilling the Cochrane criteria shows that surgeons working with a patients own bone and tissue have much better results in most of the cases compared to the use of artificial bone and artificial membranes that are offered on the medical market by a multibillion dollar industry.


Cochrane criteria

are rigorous, standardized international methods used to conduct systematic reviews of healthcare interventions, ensuring high-quality evidence.


gold standard

refers in medicine to a diagnostic, therapeutic, or generally scientific procedure that represents the most proven and best solution. New procedures are measured against this gold standard.


Where own bone and own tissue are used:

These procedures should be carried out exclusively using own bone and tissue techniques to achieve the most predictable result for each patient.

Key Procedures

Genioplasty

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

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.

Implantology

Implantology

Inflammation, injury, or prolonged tooth loss can cause the jawbone to lose volume, thus compromising the foundation needed for reliable implant treatment. In such cases, however, the bone can be deliberately rebuilt.

A range of proven procedures is available for this purpose: from bone grafts and block bone techniques to internal or external sinus lift methods. Which approach is used depends on the individual clinical findings. Modern DVT imaging and minimally invasive surgical techniques ensure precise, gentle execution throughout the process. The goal is clear: a stable, long-term load-bearing foundation that not only performs functionally but also enables a high-quality aesthetic dental reconstruction for implant treatment that stands the test of time.​​​​​​​​​​​​​​​​

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.
