Root Membrane Technique

The Root Membrane Technique is a surgical procedure performed before implant placement to induce successful osseointegration and increase the soft tissue aesthetics by minimizing the loss of the buccal bone after extraction. The procedure separates the root at the time of extraction, leaving the root partially on the buccal side. As a result, it’s possible to maintain the physiological relationship with the buccal side without deterioration.

Until now, the Root Membrane surgical procedure was performed only by highly skilled dentists. We released this kit to make the surgical procedures one that can be performed by more and more dentists. By following the step-by-step instructions, the tissue can be entirely protected with the precise tooth modification.

Within the buccal side of an immediate implant placement in the anterior maxilla, there are cementum, PDL, attachment fibers, vascularization, and bundle bone. This procedure leads to continuous and predictable osseointegration by minimizing the loss of the buccal bones caused by socket remodeling that may occur after extraction.

According to a study published in JOMI, the Root Membrane Technique is an effective alternative treatment method for immediate implant placement. It has an extremely high success rate compared to implant placement after extraction. This technique has already been recognized for its effectiveness by clinicians around the globe, as well as numerous articles and case studies.

As the studies show, when the buccal root fragment is intentionally left in place, the blood supply will be maintained smoothly, and consequently the dimensions of alveolar ridge can be preserved. On the basis of this evidence, it has been established that Root Membrane Technique is a safe treatment that yields a high implant success rate.

Also, this unique technique can ensure the dimensional stability of facial and soft tissues around the implant site without supplementary biomaterials such as bone grafts. Dento-gingival fibers retained in the root fragment increase soft tissue aesthetics when they are part of an esthetical immediate implant placement.

The 24-month radiograph showed a limitation of defect size, while the resorption traces of apex did not appear radially. There was no sign of radiopacity consistent with the defect fill for 36 months. Apex resorption of the root is confirmed.
Bottom (Left to right)
With 48 months of follow-up, the cross-section showed complete defect fill and about 1.5 mm root reabsorption. The reabsorption area is full of new bone cell with radiologic pattern and it leads new born growth.

How to use the Root Membrane Kit

how-to-root-mem-kit-01
After measuring the length of root canal, secure the root canal using the Gate Glidden Drill and Bur.
how-to-root-mem-kit-02
Use Initial Shaper (IS1) to perform an initial root split about 7mm so that lingual surface becomes slightly rounded.
Then use the Initial Shaper (IS2) to expand as the length of the root and remove the palatal side fragment.
how-to-root-mem-kit-03
Use a round Diamond Drill that matches the length and size of the rootfragment. Then trim the remaining roots forming a crescent moon when viewed from the occlusal surface.
The ideal thickest central part of Root fragment is 1.5-2mm when viewed from the occlusal surface.
Perform the initial trimming so that the crestal part of the root fragment on the gingival part descends 3 mm below the tip of gingiva.
Use the Final Shaper (FS1: for low speed or FS2: for high speed) to trim and smoothen the root fragment (Crestal) remaining below the tip of the gingiva.
how-to-root-mem-kit-04
To prevent slip of the common drill along the slot, initial drilling should be done using an initial shaper (IS2) after matching the direction in which the fixture is to be placed.
After that, it needs step-by-step drilling.
how-to-root-mem-kit-05b
Due to the feature of immediate placement, there is no resistance on the labial side, so labial shifting is likely to occur when the fixture is placed.
To prevent this, trim the palatal side bone before fixture placement by using tapered diamond.
It’s kind of counter sinking drilling. You can adjust the depth of the tapered diamond according to the diameter of the fixture being placed.
how-to-root-mem-kit-06
Place the fixture without touching the remaining root fragment.
If a gap between the root fragment and the fixture is wide, perform a little bone graft.

Perfect matching with the AnyRidge Implant System

The advantage of the Root Membrane Technique is immediate implant placement. The most effective way to ensure a high success rate is stronger initial stability. And no implant provides better initial stability than the complete line of AnyRidge Implants. They are the perfect complement to the Root Membrane Technique.

AnyRidge Knife Thread Design

The AnyRidge Implant Knife Thread® is designed as an oblique shape that features a round face and narrow thread. You can obtain optimal ISQ because the implant is placed without damaging the unique architecture of cancellous bone. AnyRidge also provides even stress distribution.

AnyRidge XPEED Surface Treatment

XPEED® surface treatment technology includes Ca2+ions, which increases the osseointegration rate on the fixture surface. There is no problem associated with the absorption of the coating layer after scaling deterioration, and the BIC and removal torque values are excellent.
