These two share the same internal conical connection and the same TiUltra surface, so their prosthetic components are interchangeable and the choice between them is purely surgical. NobelActive expands into an under-prepared site; NobelParallel is straight-walled with a tapered apex and is the more conservative of the pair.

The biggest differences
NobelActive has an expanding tapered body, a double-lead thread and reverse cutting blades that allow the implant to be redirected during placement. NobelParallel is parallel from platform to just above the apex, with threads running the full length and a tapered tip that Nobel Biocare describes as supporting bi-cortical anchorage. One is designed to create its own stability by compressing the site; the other is designed to be predictable in a site that already has enough bone.
Where they are alike
Both carry Nobel Biocare's internal conical connection, both are offered with TiUltra and were catalogued historically with TiUnite, and both follow the same length convention in which the actual implant measures 0.5 mm less than the figure in the product name. Both are also described with an S variant offering enhanced platform shifting, although Nobel Biocare does not publish the shift dimension on the pages we reviewed.
Design
NobelActive is catalogued at 3.0, 3.5, 4.3, 5.0 and 5.5 mm; NobelParallel at 3.75, 4.3, 5.0 and 5.5 mm. If a 3.0 mm implant is required within this connection family, NobelActive is the one that offers it. Lengths overlap closely, running to 18 mm on the mid-range diameters of both.
Prosthetic ecosystem
Because the connection is shared, an abutment made for one will fit the other at the same platform size, and the two can be mixed within a case. That shared connection also extends to NobelReplace Conical Connection. It does not extend to the older tri-channel or external hex Nobel lines, which is where component-ordering errors actually happen in this brand.
What may influence clinical selection
Nobel Biocare presents NobelActive for demanding situations requiring immediate placement or immediate function, including soft bone, extraction sockets and aesthetic regions, and NobelParallel as suitable across bone qualities and indications. The honest summary is that the more aggressive design gives a surgeon more to work with in poor bone and more to get wrong; in good bone, the straightforward implant is straightforwardly appropriate.
So which is better?
Neither is universally better, and any page telling you otherwise is selling something.
These are different designs with different trade-offs, and the right choice depends on the
bone available, the position in the mouth, the planned restoration, and what the treating
clinician is equipped and experienced to place and to service years from now.
That last point is easy to overlook and matters more than most specification
differences: components need to remain obtainable for as long as the implant is in place.
Regulatory record
US FDA 510(k) clearances held by each side, retrieved from the FDA's own database.
Clearances are held at brand level, so every system from the same brand shares this record.

A clearance count is not a quality ranking, and the
larger number is not the better implant. A brand with more clearances usually
has a longer history or a broader component range. FDA "clearance" also is not FDA
"approval" — it means the device was accepted as substantially equivalent to one already
on the market, generally without a clinical trial. A blank here means we could not match
a filing with confidence, not that the brand lacks authorisation.
