This titanium mesh membrane is manufactured in 9 different configurations so you can graft sites where a stable implant has been placed but the surrounding bone is insufficient. It features an opening that allows you to secure the membrane (graft) in place. Several of the different designs feature a 100 degree bend which provides ample space for GBR. The design features a wider titanium mesh to allow for more buccal bone growth. i-Gen can be used with most of the popular implant systems.

How to Use i-Gen

Ideal Regeneration Membrane

  1. Place an implant into the recipient site.
  2. Connect a flat abutment to the implant and bone graft. Usually 1 mm cuff height is good enough for vertical space, but 2 or 3 mm cuff height of flat abutment can be chosen according to situation. The amount of graft material should be enough to fill the space between i-Gen and the fixture.
  3. Selection of i-Gen and placement. According to the size and shape of bone defect, an i-Gen can be chosen from 12 different shapes. Match the hole of i-Gen with the screw hole of flat abutment.
  4. Fixate i-Gen with a healing abutment. Choose a healing abutment or cover screw to fix i-Gen membrane depending on the need of one or two stage surgery. And tight adaptation of soft tissue flap is recommended.

Which i-Gen?

i-Gen Membrane has 9 different sizes and shapes.

As seen on the figure left, alveolar bone has different widths according to locations. It can be divided into three categories; Anterior (Light Blue dots), Premolar (Blue dots) and Molar (Purple dots). For Anteriors, ‘narrow’ membranes can be used, which has 4.5mm buccal horizontal extension from the center of fixture. For Premolars, ‘Regular’ membranes which has 5.5mm buccal extension, can be selected. The molar area usually needs wide membrane (6.5mm from fixture center), especially at the immediate placement case with wall defects.

Type A and B membranes are only to cover single wall defects. Type C has a lingual extension to cover lingual wall defect. Type C has a lingual extension to cover lingual wall defect.

Clinical Case

Case I. Mandibular premolar

Fig 1. This 65 year-old male patient visited with a chief complaint of discomfort on #24 during chewing. On the panoramic view, large bone defect was observed.

Fig 2. The tooth was extracted and socket was degranulated thoroughly. A 4.5 mm AnyRidge fixture was placed at the center of socket with excellent initial stability.

Fig 3. A flat abutment, 1 mm cuff height, was connected with the fixture. A 1.6mm hex driver is needed to place a flat abutment, which is included in the kit. Mega-Oss allograft was grafted into the defect.

Fig 4. The combined image of i-Gen, a flat abutment and a healing abutment. A healing abutment was connected on the Flat abutment to fix the i-Gen for one stage surgical approach. Watch the horizontal extension of i-Gen.

Fig 5. Simple suture was made to adapt the buccal flap against the healing abutment.

Fig 6. Postoperative panoramic and intraoral radiograph.

Fig 7. 3 months after surgery. Gingival healing was excellent and intraoral radiograph showed considerable increase in radiopacity.

Fig 8. Usually flap opening is not necessary to remove i-Gen, but in this case the flap was elevated to check the bone regeneration. The i-Gen was maintained very stable in the tissue, and it was easily removed with a hemostat.

Fig 9. The defect was filled with healthy regenerated bone. From the occlusal view, the buccal bone has more than 3mm width at the level of implant platform.

Fig 10. Flap was closed with simple suture.
