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

ImplantLocking taper concept impacting the
female taper of the implant head with the male
counterpart on the root structure.

has a tapered rod or socket for connection to
the root

NobelActive (TiUnite) and Alpha Bios 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 Bios 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
Straumanns Surface

NobelActive Marketing Claims
Questionable Validity of Marketing Claims

• 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?

• 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 dont
  cut through bone like

conventional implants, they press through it like
a corkscrew

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.

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

ReActive with Tri-Lobe Connection and Platform
Switching

• 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
