Design Concept
Easy and Fast Insertion
1) Sufficient cutting force can be obtained even at low RPM. Autogenous bone can be harvested within 10 seconds!2) Amount of bone harvested may be equivalent to the size of Auto-Max! 3)Enables quick, easy bone harvesting in a single procedure! 4) It can be cleaned thoroughly as the Stopper is easily disconnectable!5) V shaped opening completely prevents bone chips from splattering during drilling!6) May be used in any type of bone with excellent durability!
Connection status when start.
Stopper- Material : Ti-6Al-4V(Titanium alloy)- Coating : TiN Coating
Wide opening to permit easy removal of harvested bone
Designed for easy connection & disconnection
Optimally designed so that bone does not escape.
4mm Stop
Unique sliding design for smooth lifting of Stop-per with appropriate resistance as drilling pro-gresses
Designed to connect the Stopper securely.A ledge to secure the position of Stopper at start
Center guide to prevent slippery during drilling
Equipped with optimal blade area, bone can be harvested with low RPM
Auto-Max Material : S42010
1. Connect an Auto-Max o the handpiece and position a stopper on the Auto-Max.
2. The Auto-Max should meet the bone surface perpen-dicularly. Press the handpiece to fix the sharp point on the bone and start drilling at about 500RPM with copious irrigation.
3. Do not pump during harvest. Pumping may scatter the harvested bone.
4. The Auto-Max will automatically stop advancing into the bone at a depth of 4mm.
5. Disconnect the stopper from Auto-Max and collect particulated autogenous bone at in a sterilized tray.

Superior porous structure
No crystallization with standard fusion temperature
Mega-Oss BovineTM is an inorganic natural bone material extracted from bovine bone from Australia which is recognized by BSE as safe and clean region. (Korea is not recognized by BSE as clean area.) The organic part of the bovine bone is effectively removed through various pro-cesses, no additives are added during processing, and it has no immunological rejection. All the products are produced in sterile processes from safe raw materials. Mega-Oss BovineTM is biocompatible bone graft material with porous structure similar to human cancellous bone and stimulates new bone formation and growth in grafted site. It has more and wider pores offering excellent hydrophilicity and angiogenesis.
The Low-Temperature deproteinizing process eliminates proteins effectively, but maintains the natural topography of cancellous bone with superior porosity.
The new gold standard for Xenograft
Mega-Oss BovineTM sincerely wants to be compared in quality with Bio-OssⓇ(Geistlich, switzerland), which has the biggest market share in the world.

AnyRidge, Thinking Man’s Privilege
■Guarantee excelllent initial stability always!
■Less reduction and better preservation of cortical bone
■Wider implant possible than the cortical width
■Strong body and greater surface surface area
The powerful self tapping thread provides incredible initial stability with increased resistance to compressive force while minimizing the generation of shear force.
As the core is narrow & uniform, the implant can be placed into a horizontal bone incision during ridge splitting resulting in better initial stability and less stress to the bone.
AnyRidge macro shape helps maintain more buccal and lingual cortical bone than any other implant system in the market today. The unique shape of the implant with a narrow core and varying thread depths enables wider diameter implants to be placed into narrow ridges.

Step by step Procedures of Ridge Split Technique
Step 1.Indications
Ridge Splitting techniques may be used in any cases presenting a narrow ridge. Single implant or limited space cases however, offer less room for explansion.
If the narrow ridge consists solely of cortical bone, with no intervening ancellous bone, it will be difficult to achieve a good ridge split.
Caution is also advised in the maxillary anterior as ridge splitting may cause the labial cortical bone to move too labially, resulting in severe angulation of the implant.
Step 2Incision
Incision line is recommended to be at the center of remaining keratinized tissue.
A longer horizontal incision is better to per-mit adequate sawing for ridge splitting. -- one tooth-size more, mesially and distally.
Step 3Flap reflection
Full thickness or Full-to-partial thickness flap is recommended.
If the ridge crest is less than 2 mm, it is advis-able to reduce the crestal bone until the width is at least 2mm.
34 | 35MEGAGEN Implant
Thor & BonEx kitTM
Step 5Drilling
Now drill the desired position and axis of implant.
In ridge expansion technique, lance and 2mm drilling is enough in most cases. It’s only to guide the implant path. If a flat-bottomed implant was planned, drilling should be extended to the diameter recommended by the manufacturer.
Step 4-1Chiseling (optional)
If the crest is less than 2 mm, it’s better to expand with a chisel first.
It is to avoid bone defects which can be made with drill-ing on the thin ridge.
Light tapping with a mallet will be enough.
Step 4Sawing
Sawing starts from the center of ridge.
The ridge should be cut at a slightly buccal angulation, because resorption oc-curs on buccal bone. If the lingual bone is too thin after sawing, splitting may occur to the lingual side, making implant position too far lingual.
Thin ridged bone should be cut to the depth of implant length. For example, if the intended implant length is 8.5mm, the incision should be cut to 8.5mm.
In most cases, vertical bone cutting is not necessary when you place AnyRidge implant. Only small offsets at the ends of horizontal bone cutting are enough to guide the direction of ridge expansion, if needed.
Try to maintain lingual bone thicker than buccal to expand thin ridge buccally
Slightly angulated cutting is recommended.
Step 5-1Expanding with BonEx kit (optional)
When the wider inside, slow expansion with BonEx kit is recom-mended.
The Expanders can be engaged easily with bone by a handpiece(50 Ncm). If it stops before the depth of osteotomy, use a hand wrench and a ratchet exten-sion. Same procedure can be repeated with wider diameter of BonEx Expander.
Step 7Bone graft & Membrane
The remaining bone defects can be filled with any kind of bone graft material. Resorbable membrane is recommendable for better bone filling.
Closing flap
One stage or two stage approach can be chosen according to the conditions, but it is recommended to finish several cases with successful result before trying one stage surgical approach.
Adequate periosteal releasing incision is need-ed if primary closure is planned.
Step 8Step 6Implant placement
When the ridge is expanded adequately or has enough flexibility, place the implants.
If you use BonEx Expanders, it’s better to leave an Ex-pander during placement of the first implant to keep the ridge expanded.
Torque force up to 60-70 Ncm will be fine to place an implant.

Mandibular Posterior
Clinical case
A 79 year-old female patient visited with a chief complaint of chewing difficulty on the mandibular molar area. She had been using a denture for more than 30 years. The ridge stal bone, which needs ridge augmentation. She was physically healthy. Considering her age, the ridge split technic was decided to do.
The ridge width was about 3mm on the crest.
The ridge was splitted with a thin saw only horizontally to the depth of implant length (11.5, 10, 8.5 and 7mm from front to back, respectively), then 2mm lance drilling was done. Compare the drilling site with ridge width.
Preoperative panoramic radiograph
Fixtures were placed with a handpiece which was set on 40 Ncm torque force. Each fixture stopped at the level shown on the pic-ture. Then the fixtures were screwed down with a torque wrench, one full turn on each fixture sequentially.
All the fixtures were placed completely, 1 mm under the crest in con-sideration of bone remodeling. The crestal bone was split enough to make ideal width.

On the intraoral and radiographic examinations, she showed problems on many teeth, but she wanted to treat edentulous area first. Both mandibular molar area showed thin ridges which needed to be augmented for implant placement.
Preoperative panoramic radiograph and intraoral views.
When the flap was reflected on the right side, the ridge width was less than 3mm. The ridge was saw with a Thor horizontally to the depth of 10 mm.
Only a lance drilling (2mm in diameter) was made on the anterior two implant sites, and 2.9mm drilling was done on the second molar area. Then 4.5 x 10 mm AnyRidge implant were placed for the two molars. The 50Ncm-set handpiece stopped at the level shown at the center picture.

The first molar implant was placed. Due to the special structure ofthe AnyRidge Implant system, the cortical bone on the top showed green-stick fracture during placement, but when the implant was placed completely under the crest, the fractured bone came back to the original position.
3 months after the ridge split and implant placement, the second stage surgery was made with simple incision and flap, just by splitting the remaining keratinized tissue into two, despite its being limited. The bone was regenerated excellently.
4mm diameter healing abutments
were connected. Smaller diameter healing abutments are recommend-ed in the case of limited keratinized tissue in order to help preserve the tissue.Final restorations were delivered following routine procedure. All implant prosthetics were made as
single crowns.
At the first follow-up visit after 3 months from final restoration de-livery, the gingival condition had
improved. The patient was very sat-isfied with the result, and wanted to have more implants for other teeth.

Maxillary premolar
A 53 year-old female patient visited with chief complaints of discomfort during chewing on the maxillary left posterior. On the clinical and radiographic examination, the first premolar which was an abutment of three unit bridge revealed subgingival decay under the crown. So it was decided to extract it and place two implants on the premolars.
Upon extraction and flap reflection, the ridge on the second premolar showed thin ridge.
Two 3.5mm implants were placed with excellent stability. During placement, green stick fracture was made on the second premolar area.
Thin ridge was splitted with a Thor, and drillings up to 2.9mm were made.

This patient showed extremely thin ridge on the mandibular posterior. The ridge width was less than one mm on the crest. In a case like this, the alveolar process is mainly composed with cortical bone without cancellous bone inside. It needs careful splitting to prevent total fracture of the cortical plate.
A specially designed Thor’s saw can start splitting even on this narrow ridge without reduction of the sharp edge. The horizontal cut went down to the depth of implant fixture, but no vertical incisions were done.
After 2 mm drilling to guide the path of bone expanders, three expanders from 2.4 to 3.3 were used. The first implant was placed while an expander was in position to keep the expanded ridge.
The Ridge Expander kit was used to expand the thin ridge slowly.

Four implants were placed completely with excellent initial stability. A green stick fracture was made on the mesial of first premolar.
Mega-Oss allograft was grafted into the bone defects between implants.
Three months after ridge split and implant placement, a simple second stage surgery was made. The alveolar bone around implant was regenerated fabu-lously with enough width. Compare with the initial photo.
Maxillary lateral incisor case
A 52 year-old gentleman wanted to exchange his old PFM bridge on the maxillary anteriors. During treatment, he wanted to place an implant on the missing area of lateral incisor to make single crowns on each teeth.
The ridge was thin due to resorption with a big undercut on the labial plate.
The thin ridge was splitted with a Thor. In this case, due to limited space, a vertical bony cut was made on the mesiolabial margin of canine. The vertical cut was oblique in the bone not to make damage on the root of canine.
A 2mm diameter of drill was used to guide the path of an implant.

The implant was completely placed with a hand wrench. During placement, a small green stick fracture was made on the mesial side.
Mega-Oss allograft and a collagen membrane was placed to cover the defect.
Primary closure was made and the healing was uneventful.
Intraoral radiographs taken at 1month after surgery, during impression taking, after final restoration.
Second stage surgery was made with simple 3 corner flap. And final restoration was delivered following routine procedures.

How to use
Ideal + Regeneration membrane ⇨ i-Gen membrane
1. Place an implant into the recipient site.
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 i-Gens. Match the hole of i-Gen with the screw hole of flat abutment.
2. Connect a flat abutment to the implant and bone grafting. 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.
4. Fixate i-Gen with a healing abutment. Choose a healing abutment or cover screw to fix i-Gen membrane depend on the need of one or two stage surgery. And tight adaptation of soft tissue flap is recommended.

i-Gen membrane has 12 different size and shapes.
As seen on the figure left, alveolar bone has different widths according to locations. It can be divided into three categories; Anterior(Pink dots), Premolar(Blue dots) and Molar(Green dots). For Anteriors, ‘narrow’ mem-branes can be used, which has 4.5mm buccal horizontal extension from the center of fixture. For Premolars, ‘Regular’ membranes which has 5.5mm buc-cal 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. Type D has no hole for a Flat abutment, so it can be used for ridge augmentation of multiple teeth, Due to the need to fixate the membrane with tags, Type D has 4 small holes at each corner.

Clinical case
. Mandibular premolar
This 65 year-old male patient visited with a chief complaint of discomfort on #24 during chewing. On the pan-oramic view, large bone defect was observed.
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.
The combined image of i-Gen, a flat abut-ment and a healing abutment.
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.
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.
Simple suture was made to adapt the buccal flap against the healing abutment.
3 months after surgery. Gingival healing was excellent and intraoral radiograph showed considerable increase in radiopacity.
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.
The defect was filled with healthy regener-ated bone. From the occlusal view, the buc-cal bone has more than 3mm width at the level of implant platform.
Flap was closed with simple suture.
Postoperative panoramic and intraoral radiograph.

. Maxillary premolar
The first premolar was extracted due to severe periodontitis. Due to the inflam-mation around that tooth, the implant surgery was delayed almost a month.
When the flaps were elevated, there found two dif-ferent bone defects: The first premolar showed large extraction socket defect due to periodontitis, and the second premolar showed quite big undercut on the buccal bone.
Ostetotomy sockets were made. A big fenestration de-fect on twas made he second premolar due to bony undercut.
Two 4 x 13 AnyRidge Xpeed fixtures were placed at thwith excellent initial fixation. Look e defects around both implants.
Flaps were closed with simple interrupted sutures, and panoramic and intraoral radiographs were taken after surgery.
Healing was uneventful for a month. Intraoral radiograph was taken one month later from surgery.
Two regular size i-Gen (Type A) was fixated with healing abutments.
The defects were grafted with the mixture of Mega-Oss(allograft) and Bone Plus (synthetic, BCP)
Two Flat abutmentscuff height, were, 2mm connected due to the irregularity on the crestal bone.

. Mandibular incisor area
The first premolar was extracted due to severe periodontitis. Due to the inflam-mation around that tooth, the implant surgery was delayed almost a month.
Two fixtures were placed on into both lateral incisors. Due to the ver-tical defect, fixture platforms were positioned about 3 mm above the crest. And again 3mm cuff height Flat abutments were connected to the fix-tures to make more space under the membrane.
Mega-Oss bovine was grafted on the horizontal and vertical defects.
Two narrow Type C i-Gen membranes were positioned and fixated with cover screws. Then a collagen mem-brane was placed at the center of the defect.
Intraoral radiographs taken 1 month after surgery. Find the position of fixture platform, a Flat abutment and i-Gen membrane.
A panoramic radiograph taken immediate after surgery.
Primary closure was made with the periosteal releasing.
Starting package
※ Individual items can be ordered separately to fill up the package.※ Different connections of Flat abutment for Different implant system are available upon special orden. Ask to your sales reps.
Due to the difficulty to recognize the size and shape of bone defects before surgery, it is not easy to order an i-Gen membrane and components on each patient whenever needed.So a starting package which includes everything for i-Gen, should be set at surgery room. And it is strongly recommended to fill up the empty space immediately after surgery for the next case.
