NobelActive Internal and External Hex Implants Nobel Marketing Claims this is the “Implant of the Future”


Slide2 l.jpg

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

Screw-Vent Internal Hex/bevelNiznick Patent 1986

Astra 11Deg. Bevel

NobelActive hex too deep to allow for 8mm implant length

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

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

Oraltronics’ Pitt-Easy Implant with Deep Apical Threads

Alpha Bio Clone with Conical Connection

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

1.5mm High External Hex 3.5mm Morse Taper Post

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

“Those who cannot remember the past are condemned to repeat it” QUOTATION:George Santayana (1863–1952), U.S. philosopher,

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 ImplantLocking Taper Concept “The head member has … a tapered rod or socket for connection to the root”

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 l.jpg

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

“self-drilling”

“ability to change direction during surgery”

“unique press-fit connection of abutment –

-removes risk of excess cement”

NobelActive Internal and External implants don’t cut throughbone like

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

Self-threading – like any screw in soft bone.

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

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

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

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

Nobel Biocare’s NobelActive Marketing Claims

NobelActive Marketing Claims

Questionable Validity of Marketing Claims

conventional implants, they press through it like a corkscrew


Slide8 l.jpg

NobelActive External Claims

Claims are not Valid

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

  • 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.

  • 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

  • “One piece implant

  • design with 2-piece flexibility”

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

Dense Bone Drill is 4.6mmD but Platform is 3.9mmDNobelActive Leaves Gap around neck of Implant in Dense Bone

Narrow Neck of NobelActive Requires Bone and Soft tissue Grafting to fill defect left at crest of ridge

Why change drills and platforms just to change threads l.jpg

Why Change Drills and Platforms, just to change threads?

NobelActive

ReActive

RePlus

  • RePlus and ReActive have compatible Tri-Lobe Connection

  • Both have Platform switching interface – of questionable value

  • Both have even taper to allow insertion into an undersized socket for bone expansion,

  • Nobel Active has straight outer threads with very tapered inside thread dimension

  • RePlus and ReActive have Mini-threads whereas NobelActive has horizontal grooves.

  • RePlus and ReActive seal opening at crest of ridge whereas NobelActive 4.3 & 5.0 implants are narrower at top, leaving gap

  • RePlus and ReActive have double lead threads on body for faster insertion.

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

NobelActiveNo Taper to OD of Threads

ScrewPlantGradual Taper for Bone Expansion

  • NobelActive™ Claim

  • The 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.

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

ReActive 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
