3 orthodontic Bone anchor (oba) SYStem The Orthodontic Bone Anchor (OBA) System is a plate and screw system designed to be implanted intraorally and used as an anchor for orthodontic procedures. the plate anchor portion of the system consists of t-shaped plate anchors which are attached to the bone via 1.55 cm cortex screws and 1.85 mm emergency screws. the plate anchors are offered in various designs for attachment to the orthodontic device. the screw anchor portion of the system consists of 1.55 mm self-drilling and self-tapping screw anchors which incorporate a non-threaded gingival collar beneath the screw head which protects the soft tissue. It includes screw anchors, plate anchors, instruments, and a module case for storage and sterilization. Provides fixed anchorage for improved control of tooth movement compatible with a variety of orthodontic devices including archwires, elastics and springs allows immediate loading Plate anchors can be adapted to the patient s bony anatomy manufactured from commercially pure (cp) titanium and titanium alloy* for biocompatibility Plate anchor Profile of an archwire in a screw anchor Screw anchor Screw Anchors thread diameter of only 1.55 mm for placement between tooth roots two through-holes in screw head accept archwires with a cross section of up to in. x in.

5 Indications and Contraindications Indications The Orthodontic Bone Anchor (OBA) System screw anchors are intended to be implanted intraorally and used as an anchor for orthodontic procedures in adolescents greater than age 12 and adults. The Orthodontic Bone Anchor (OBA) System plate anchors are intended to be implanted intraorally and used as an anchor for orthodontic procedures in adults. Contraindications The Orthodontic Bone Anchor (OBA) System is contraindicated: When cortical bone is less than 5 mm thick, or when there is insufficient quantity or quality of bone In deciduous or mixed dentition When active or latent infection is present In patients with an abnormal habit of mastication, as this may affect the retention and stability of the device after implantation These devices are intended for single use only and are provided NONSTERILE only. MR INFORMATION This device has not been evaluated for safety and compatibility in the MR environment. This device has not been tested for heating or migration in the MR environment. 4 DePuy Synthes CMF Orthodontic Bone Anchor (OBA) System Surgical Technique

6 Implanting a Screw Anchor 1 Locate the implantation site Choose the implantation site according to the treatment objective and the quality and quantity of bone. Confirm that the implantation site allows adequate clearance from the tooth roots. Choose the screw anchor with the appropriate thread length: 6 mm and 8 mm self-drilling or 10 mm self-tapping. Precaution: To avoid damage to anatomic structures, place implant away from tooth roots, tooth buds, vessels, nerves, and/or sinuses. In adolescent patients, care should be taken to avoid sutures and other areas and structures that are not fully developed. 2 Prepare the implantation site If desired, make a small incision at the implantation site and dissect through the soft tissue to the bone. Warnings These devices can break during use (when subjected to excessive forces or outside the recommended surgical technique). While the surgeon must make the final decision on removal of the broken part based on associated risk in doing so, we recommend that whenever possible and practical for the patient, the broken part should be removed. Instruments and screws may have sharp edges or moving joints that may pinch or tear user s glove or skin. Precautions Drill rate should never exceed 1,800 rpm. Higher rates can result in thermal necrosis of the bone, soft tissue burns, and an oversized hole to be drilled. The adverse effects of an oversized hole include reduced pullout force, increased ease of the screws stripping in bone, and/or suboptimal fixation. Always irrigate during drilling. Avoid drilling over nerve or tooth roots. Take care while drilling as to not damage, entrap, or tear a patient s soft tissue or damage critical structures. Be sure to keep drill clear of loose surgical materials. Handle devices with care and dispose worn bone cutting instruments in a sharps container.

7 Implanting a Screw Anchor 3 Implant a 6 mm or 8 mm screw anchor Instruments Screw Anchor Cruciform Screwdriver Blade, with Spring Holding Sleeve, short Screwdriver Handle with hex coupling, large Screw anchor mounted on screwdriver blade with holding sleeve Optional instruments mm Drill Bit, J-latch, 44.5 mm, 6 mm stop or mm Drill Bit, J-latch, 44.5 mm, 8 mm stop Note: To implant a 10 mm self-tapping screw anchor, continue with Steps 4 5. Using the screw anchor cruciform screwdriver blade with spring holding sleeve, short and the screwdriver handle with hex coupling, load the screw anchor of the desired length and implant it until the distal lip of the screw anchor head sits on top of the soft tissue. If a pilot hole is desired, use the appropriate 1.25 mm drill bit with stop and a surgical power drill. Irrigate thoroughly to prevent overheating of the drill bit and bone. Notes For optimal retention, insert screw perpendicular to cortical bone Please see Page 5 for Warnings for Instruments and Precautions for Drill Bits 4 Drill a pilot hole for a 10 mm self-tapping screw anchor Instrument mm Drill Bit, J-latch, 44.5 mm, 10 mm stop Before implanting a 10 mm self-tapping screw anchor, drill a pilot hole using the 1.25 mm drill bit with 10 mm stop and a surgical power drill. Irrigate thoroughly to prevent overheating of the drill bit and bone. Important: Always drill a pilot hole for the 10 mm self-tapping screw anchor. 6 DePuy Synthes CMF Orthodontic Bone Anchor (OBA) System Surgical Technique

9 Implanting a Plate Anchor 1 Locate the implantation site Choose the implantation site according to the treatment objective and the quality and quantity of bone. Confirm that the implantation site allows adequate clearance from the tooth roots. Select plate design (mesh pad, bracket or domed). Consider in advance the reshaping and/or trimming of the plate that may be required to conform to the patient s bony anatomy. Precaution: To avoid damage to anatomic structures, place implant away from tooth roots, tooth buds, vessels, nerves, and/or sinuses. 2 Prepare the implantation site Make an appropriately sized incision where the plate anchor neck will protrude through the soft tissue, orienting the incision perpendicular to the long axis of the plate anchor neck, and dissect through the soft tissue to the bone. Make a subperiosteal pocket large enough to allow insertion of the plate anchor and implantation of the plate anchor screws. 8 DePuy Synthes CMF Orthodontic Bone Anchor (OBA) System Surgical Technique

10 Implanting a Plate Anchor 3 Reshape and/or trim the plate anchor Instruments universal Bending Pliers, for 1.0 mm, 1.3 mm, 1.5 mm, 2.0 mm Plates Plate Cutter, for 1.0 mm, 1.3 mm, 1.5 mm, 2.0 mm Plates The plate anchor may need to be reshaped and/or trimmed to conform to the patient s bony anatomy. If so, use the universal bending pliers and/or the plate cutter. The plate anchor has a T-configuration, but it may be trimmed to an L- or I-configuration if required. If desired, use the universal bending pliers to reshape the plate anchor neck where it will protrude through the soft tissue. Precaution: If contouring is necessary, avoid sharp bends, reverse bends, or bending the implant at a screw hole. Avoid notching or scratching the implant. These factors may produce internal stresses which may become the focal point for eventual breakage of the implant. Note: Please see Page 5 for Warnings for Instruments and for Precautions for Drill Bits. Orthodontic Bone Anchor (OBA) System Surgical Technique DePuy Synthes CMF 9

While holding the plate anchor in the desired location in the subperiosteal pocket, use the matrixmidface screwdriver blade and the screwdriver handle with hex coupling to implant the first plate anchor screw. Notes For optimal retention, insert screw perpendicular to cortical bone If the plate anchor screw becomes loose in the bone, remove the screw and replace it with the appropriate length OBA titanium plate anchor emergency screw repeat this process for the remaining screws. It is recommended to use at least three (3) screws to secure the plate anchor. If pilot holes are desired, make one for each screw using the appropriate 1.25 mm drill bit with stop and a surgical power drill. Irrigate thoroughly to prevent overheating of the drill bit and bone. 10 DePuy Synthes CMF Orthodontic Bone Anchor (OBA) System Surgical Technique
