Cranial Bone Fixation
We have shown that our experience with bone fixation of the pediatric skull and face using a bioresorbable implant system with ultrasound-aided pin fixation is safe and effective in a variety of pediatric neurosurgical procedures. Fixation of the bone is rapid, efficient, and stable, providing satisfactory cosmetic results over time.

Conclusions: Due to fixation in cortical as well as cancellous bone ultrasound aided fixation using resorbable osteosynthesis materials is more stable than screw fixation. The time required for application is considerably shortened as no thread cutting is required.

Facial Trauma Osteosynthesis – Cranial & Maxillofacial Surgery
Our results show that this resorbable osteosynthesis system with melting and welding procedure of the pin allows for safe intraoperative handling with a low complication rate. These findings correspond with other recent experimental as well as clinical reports. The fact that 16 surgeons at different levels of experience participated in the study means that a successful utilization of this technology does not depend on specific skills, respectively, and that only a limited degree of training is required.
In accordance with other studies, our postoperative follow-up also showed sufficient mechanical stability in all the described indications.

The achieved outcomes are satisfying: it is time-saving, less costly, and osteosynthesis of craniofacial bones is firmer. We are going to validate it for the management of mandibular fractures in adult patients.
The experience here reported suggests to validate this system to manage the fractures of the middle third of the face in pediatric patients. As for its use to manage jaw fractures in pediatric patients it cannot be validate yet, except for single-sided fractures, compound fractures, mesh fractures or undisplaced fractures.

Preprosthetic Bone Augmentation – Oral Surgery
… there are many advantages to using the resorbable SonicPins and Resorb-X foil panels for augmenting alveolar ridge defects—a second surgical procedure is not necessary to harvest bone, and the handling and placing the pins and foil is easy and provides excellent support for the underlining mucoperiosteum for particulate bone grafting.

For pre-implantologic bone augmentation, the ultrasound-based SonicWeld-technology — introduced by Dr. Iglhaut—represents a method of choice. The high strength of the resorbable PDLLA membranes has proved to be highly useful for three-dimensional alveolar ridge augmentation. The primary objective of this method, which consists in avoiding the use of bone block grafts, has already been successfully achieved by the author in more than 40 cases.
The SonicWeld Rx® technology enabled surgeons for the first time to perform a stable 3-D reconstruction by using shapeable and resorbable shells.
