NobelActive Internal Hex Implant with Long Lead-in Bevel Nobel Marketing Claims this is the “Implant of the Future”


NobelActive Internal Hex Implant – Modified Alpha Bio Implant Nobel Marketing Claims this is the “Implant of the Future”

Bevel and Internal Hex


Screw-Vent Internal Hex/bevelNiznick Patent 1986

NobelActive is a Conglomeration of Common Features that work individually but not necessarily in combination

Astra 11Deg. Bevel

Osstem’s double Threads over entire length. NobelActive transition of sharp to flat threads not contusive for self-tapping insertion in dense bone

Oraltronics’ Pitt-Easy

Implant with Deep Apical Threads but

threads consistent over entire

length

NobelActive hex too deep to allow for 8mm implant length

45 Deg. Bevel Bevel with proven 20 year history of stability


1.5mm High External Hex 3.5mm Morse Taper Post

NobelActive External -With External Locking Taper ConnectionNobel Marketing Claims this is the “Implant of the Future”


NobelActive External - 5mm high tapered post requires parallelism Miter Implant with External Post – Evolved quickly to Internal Socket (Bicon)

Driskell Patent 1985: Tapered Post on Implant

“Locking taper concept – impacting the female taper of the implant head with the male counterpart on the root structure.”

Driskell Patent 1988: Tapered Socket in Implant

Locking Taper Concept “The head member has … a tapered rod

or socket for connection to the root”

Research: 1 Poster + 2 “Ongoing” Nobel Company Studies


NobelActive (TiUnite) and Alpha Bio’s SFB (SLA) Implants BUT Nobel claims 98.3% Alpha Bio study applies to its new implant

ABOVE: Nobel Claims NobelActive success of “98.3% for up to 4 years” BELOW: Alpha Bio’s Catalog Claims same 98.3% success “after more than 5 years” but the surface is SLA (sand blasted with large grit followed by acid etching) like Straumann’s Surface


Nobel Claims NobelActive Functions like “Corkscrew” Close Evaluation indicates they should have left it in the bottle


Nobel Biocare’s NobelActive Marketing Claims

1. “bone-condensing – expands indication range and gives even higher initial stability.”

2. “self-drilling”3. “ability to change

direction during surgery”4. “unique press-fit

connection of abutment – 5. -removes risk of excess

cement”6. NobelActive Internal and

External implants don’t cut through bone like

1. Higher than What – Replace? Increased stability achieved by spreading bone whereas deep threads cut bone

2. Self-threading – like any screw in soft bone.

3. Path of implant insertion should be established during surgery, not during implant insertion. That is what guide pins and end-cutting drills are for.

4. Nothing unique about press-fit connection. Miter Implant (1980) had external tapered post – evolved to internal press-fit connection of Bicon

5. If cement is a risk, why does NobelActive Internal have a screw-retained connection?

6. Why does NobelActive have spiral cutting grooves if not to “cut through bone like conventional (self-tapping) implants”?

NobelActive Marketing Claims Questionable Validity of Marketing Claims

conventional implants, they press through it like a corkscrew


1. It is not a “one-piece implant – requires an abutment.

2. Does not have 2-piece flexibility – Can not use angled heads greater than 12 degrees, ball, screw-receiving or ceramic abutments. Require parallel placement of implants for bridges.

3. A one-piece implant eliminates “micro gap” but a precise-fitting internal connections maintain marginal integrity anyway. Nobel still sells external hex implants – less stable

1. “One piece implant

2. design with 2-piece flexibility”

3. locking tapered interface .. Eliminates bone level micro gap, micro-movement and the use of abutment screws.”

NobelActive External Claims Claims are not Valid

Very deep threads apically cuts rather than compresses soft bone - any screw implant will self-tap in soft bone.

Bone Expansion

Deep apical threads will not expand narrow ridge or compress soft bone

Soft Bone (Balsa) = 3.91 in/lbs Insertion TorqueHard Bone (Oak) = 6.35 in/lbs Insertion Torque

NobelActive™ ClaimThe product is easy to use and provides high initial stability and good outcomes. The Apical Threads are too aggressive for self-tapping insertion in Dense bone and are designed to cut threads in soft bone rather than expand and compress the bone for increased initial stability. Any Implant will self-tap in soft bone.

NobelActive vs RePlus Implant From Implant DirectWhy Change Drills and Platforms, just to change threads?

NobelActive

1. RePlus has Tri-Lobe Connection 2. Both have Platform switching

interface – of questionable value3. RePlus has even taper and even

depth to threads to allow insertion into an undersized socket for bone expansion,

4. NobelActive has no taper to outside threads and extreme taper to inside thread dimension

5. RePlus has Mini-threads whereas NobelActive has horizontal grooves.

6. RePlus major diameter is at top of implant whereas NobelActive 4.3 & 5.0 implants are narrower at top, leaving gap in dense bone

7. RePlus has double lead threads on body for faster insertion.

RePlus Implant


ProActive with Tri-Lobe Connection and Platform SwitchingProjected Launch Date – January 2008

• Same taper to body as RePlus Implants allow insertion in undersized socket for expansion

• Flat-based deeper threads provide increased surface area for greater stability in soft bone


ProActive Implant Provided on Fixture-Mount that is Transfer and can be shortened to Final, Platform Switching Abutment
