are the two primary restorative dental products of the Company: 

Atlantis $^{TM}$ Custom Abutment. The Atlantis Custom Abutment system is marketed by the Company through an agreement with Atlantis Components, Inc. This product allows for a custom made restoration improving aesthetic results in dental implant procedures. 

PureForm $^{TM}$ System. Utilizing patented designs, the PureForm System is a ceramic system which allows clinicians to provide to their patients a more natural looking restoration. This easy to use concept provides the clinician a product to custom fabricate and color the crown to each patient’s individual needs. 

## Dental Regenerative Products 

The Company markets the following two product lines for use in regenerative techniques in oral surgery: 

Puros ˛  Material. The Puros Material is an allograft bone grafting material which utilizes the Tutoplast ˛ $^{3}$ tissue processing technique that provides exceptional bone grafting material for use in oral surgery. The Puros material is recognized as an excellent bone grafting material by clinicians throughout the world. Additional products are planned to come to market in the near future for additional procedures in oral surgery. 

Biomend ˛ $^{4}$ and Biomend Extend $^{TM}$ Products. Periodontal and oral surgery often require the use of a membrane to cover the surgical site. The Biomend family of collagen based membranes offer the surgeon excellent handling characteristics while typically reducing the patient’s surgery to one visit. 

## Spine Implants 

With the acquisition of Centerpulse, the Company established a presence in the spinal market. Centerpulse was one of the first spinal implant companies to introduce the ‘‘cage’’ for lumbar spine Intervertebral Body Fusion (IBF). The Company plans to continue research and development efforts in the United States and Switzerland in attempt to reinforce and expand the Company’s spinal product line categories and franchises. The Company has over ten active spinal research and development projects, including projects in the areas of fusion, non-fusion, and biologic fusion alternatives. As of the acquisition, Centerpulse offered spine products in the following five significant categories or franchises. 

BAK $^{TM}$ Vista ˛  Interbody Fusion System. The BAK Vista Interbody Fusion System is constructed of radiolucent, carbon-fiber reinforced PEEK polymer. The implant allows for unobstructed radiologic visualization, providing a new 

level of confidence in fusion assessment. Implantation of the BAK Vista system is consistent in surgical technique and instrumentation to the BAK $^{TM}$ Interbody Fusion System. 

Trinica $^{TM}$ Select Anterior Cervical Plate System. The Trinica Select Anterior Cervical Plate System features a slim, low-profile design and multiple screw options that enable the surgeon to customize the construct to each patient’s unique anatomy. The innovative locking mechanism and instrumentation set makes implantation and securing of the screws fast and simple. 

Puros ˛  Cervical Specialty Allograft. The Puros Cervical Specialty Allograft, manufactured by Tutogen Medical, GmbH, is a precision-machined radius allograft designed to offer consistent strength and sizing. The features of the graft are its four degree angle to maintain lordosis and surface texturing to minimize migration. Using the Puros Cervical Specialty graft in conjunction with the Trinica Select Anterior Cervical Plate System, surgeons can look to one source for their cervical fusions. Puros Specialty Allografts are also available for use in ALIF and PLIF procedures. 

ST360 Õ $^{TM}$ Spinal Fixation System. The ST360 Õ  Spinal Fixation System combines the benefits of an offset connector with a patented polyaxial screw technology. The ST360 Õ system also provides the surgeon with the freedom to choose implant sizes tailored to the individual patient anatomies while utilizing controlled reduction of spondylolisthesis. 

Dynesys ˛ $^{7}$ Dynamic Stabilization System. The Dynesys Dynamic Stabilization System is a new concept in the treatment of lower back and leg pain. The Dynesys System combines the surgical approach of traditional fusion with the philosophy of Dynamic Stabilization, using flexible materials to stabilize the spine while preserving anatomical function. The use of this Dynesys System continues to grow in Europe and the Company currently plans to introduce the system in other regions. The Dynesys product is undergoing an FDA approval clinical trial in the United States. 

## Trauma 

Trauma products include devices used primarily to reattach or stabilize damaged bone and tissue to support the body’s natural healing process. The most common surgical stabilization of bone fracture involves the internal fixation of bone fragments. This stabilization can involve the use of a wide assortment of plates, screws, rods, wires and pins. In addition, tissue attachment devices are used to treat soft tissue trauma. The Company offers a comprehensive line of products designed for use in the fixation of fractures, including hip fixation products, plates, screws, pins, wires and nails. The expanded trauma product line enables the
