This report describes a technique for use of resorbable mesh (Resorb-X) and an ultrasonic sonotrode unit (SonicWeld Rx) to bond a pin (SonicPin Rx) to the mesh and underlying bone for Le Fort I osteotomy fixation, precluding the need to tap, shortening the time needed for fixation, and eliminating many disadvantages of titanium. In total, 659 cases have been performed from October 2005 through December 2010. This study examined the first 103 consecutive Le Fort osteotomies performed with this resorbable system and thus those with the longest follow-up. MATERIALS AND METHODS. To assess the stability of osteosynthesis in diacapitular condylar fractures we compared fixation using ultrasound-aided resorbable pins with poly-( d,l)-lactide (SonicWeld ® Rx, KLS Martin, Tuttlingen, Germany) with that of titanium screws in 20 pig mandibles, 10 in each group. Isolated diacapitular fractures were created using a surgical chisel. Ten fractures were each repositioned and fixed by two pins (17 and 11 mm long, 2.1 mm in diameter), and 10 fractures were fixed by two titanium screws of equal length, 2.0 mm in diameter.

Shear tests were done immediately after treatment to measure the maximum force to disrupt the fixation. Fixation with pins resisted mean shear forces of 310 N until the pins fractured, whereas fixation with titanium screws failed at 918 N when the screws pulled out of the bone.
Long-term stability and resorption of pins will have to be analysed in an in vivo study. Horizontal bone augmentation of the maxillary and mandibular alveolar ridges has been conventionally performed using mini titanium alloy screws. The titanium alloy screws are used to fixate corticocancellous block grafts to the recipient site or for tenting the mucoperiosteum to retain particulate bone grafts.
Nonresorbable guided tissue regenerative membranes reinforced with titanium have also been developed to use with particulate bone grafts to augment alveolar ridge defects. This report demonstrates the use of resorbable ultrasound-activated pins and resorbable foil panels developed by KLS Martin for augmenting the alveolar ridges with particulate bone grafts. • • • • • • • PMID: 19880333 OBJECTIVES: The aim of this study was to determine the compound strength of the fixation between 2 blocks of synthetic bone using ultrasound activated resorbable pins (regarding drill hole diameter) and compare them to fixation with titanium miniscrews. Resorbable pins were up to 17 mm long. STUDY DESIGN: Two synthetic bone blocks (Sawbone) were fixed by either a resorbable pin or miniscrew osteosynthesis.
Maximum tensile forces were determined mechanically. Pin lengths of 7 mm, 11 mm, and 17 mm were analyzed in relation to different drill hole diameters. RESULTS: The ideal drill hole configuration was a combination of diameters of 2.1/1.6 mm (in a lag screw configuration).
Mean maximum tensile force was 80 N for 7 mm pins (105 N/11 mm, 69 N/17 mm). In comparison, tensile forces of titanium screws were 20 N (7 mm), 97 N (11 mm), and 135 N (17 mm). CONCLUSIONS: Osteosynthesis by resorbable pins reached equal compound strength levels compared with titanium miniscrews. This in vitro study was the basis for a clinical trial of ultrasound-guided resorbable pin osteosynthesis.

This ensures that a rigid fixation device is still in place during the reossification period—generally 6 to 8 weeks after surgery—while still eliminating the risk of palpation.

This will act as a strong catalyst for the craniomaxillofacial plate fixation market, particularly so for pediatric indications. MRG’s US Markets for Craniomaxillofacial Devices 2011 report provides critical insight into emerging trends that will fuel product adoption and market growth for craniomaxillofacial plates and screws, bone graft substitutes, cranial flap repair devices, distraction osteogenesis devices, and temporomandibular joint replacement devices through 2015. Additionally, the report provides a comprehensive breakdown of procedure volumes, unit sales, average selling prices, and revenues by device type.
