Restoring on the i-Fix platforms.

Start from the connection, not the series name

The name on the box tells you less than the platform underneath it. IP and AK run on the NP connection, SP, S-Fix Pro and AK* on RP, ZE on its own zygomatic multi-unit connection, and B and C are one-piece implants that carry their prosthetic post already, so they have no separate abutment connection at all. AK* is the one most often got wrong: it sits on RP in spite of the AK name, and takes the SP component set rather than AK’s.

• NP connection, 2.25 mm A/F hex, 12° Morse taper, M1.6 screw: IP Series, AK Series
• RP connection, 2.50 mm A/F hex, 11° Morse taper, M2.0 screw: SP Series (S-Fix Pro), AK* Series
• Zygomatic multi-unit, 2.25 mm A/F external hex: ZE Series
• One-piece, prosthetic post integral to the implant: B Series, C Series

IP+ runs on its own connection, 2.45 mm A/F with a 45° taper and an M1.8 screw. It does not take NP components, and its own set is not published yet.

Read the code, not the name

Component names repeat across platforms. A straight multi-unit abutment with a 1.5 mm collar exists on both NP and RP, and they are different parts. The codes do not repeat, and they are built to be read: the family, then the geometry, then the dimensions in the order the catalogue quotes them. On the RP set the code carries a leading K, which is the fastest way to tell the two platforms apart on a picking list.

Record the implant system, platform and implant article/reference code at placement. "4.0 × 11" with no series and no code cannot be restored by anyone who was not in the room.

Choose engaging or non-engaging

Most single-unit abutments are listed twice, once with hex and once without, and the choice is structural rather than a preference. Engaging components are generally indicated for single-unit restorations where anti-rotational stability is required. Non-engaging components are commonly used for splinted multi-unit restorations to facilitate a common path of insertion. UCLA and Ti Base abutments both come in the two forms, coded UCH and UCNH, TBH and TBNH.

• Single crown: engaging, the hexed version
• Splinted bridge across two or more implants: non-engaging
• Multi-unit abutments are already non-engaging by design, so the question does not arise on them

The zygomatic and one-piece sets are separate

ZE has eleven dedicated components on its own 2.25 mm A/F external-hex connection, covering straight and angled multi-units at 17° and 25°, healing caps, impression and temporary copings, analogs and screws. The one-piece B and C implants need far less, because the abutment is part of the implant: an impression coping, an analog and a burn-out cap. Those three are supplied on request and do not yet carry published article codes.

The B and C components are ordered by description rather than by code until the codes are assigned. Say which series when you ask.

Overdentures run on ball or locator abutments

An implant-retained overdenture gains retention and stability from implant attachments while support may be provided by the implants, residual ridge, or a combination depending on the prosthetic design, and the portfolio carries two routes to it. A ball abutment presents a round stud that the denture clips over, and a locator abutment presents a lower-profile connection in the same role. Both are listed by collar height: select the appropriate collar height according to peri-implant tissue height while also considering prosthetic space, implant angulation and the requirements of the selected attachment system. Both are supplied with a housing that is processed into the denture and an analog for the laboratory model.

• Ball abutments in 1, 3 and 5 mm collars: BA01, BA03 and BA05 on NP, KBA01, KBA03 and KBA05 on RP
• Locator abutments in 0, 2, 4 and 6 mm collars: LA00 to LA06 on NP, KLA00 to KLA06 on RP
• The housing packages and the ball abutment insertion tool are common parts: ball housing BAHP1 or BAHP2, locator housing LAHP2, and the insertion tool BAIT01

The abutment touches the implant, so it is platform-specific and carries the K on RP. The housing processed into the denture sits above it and carries no K on either platform.

One workflow connects every stage above

Every stage above answers one question in a single sequence, and it is worth seeing that sequence as one line rather than as ten separate topics: a healing abutment shapes the tissue, an impression or a scan records the site, the abutment is selected against tissue height, restorative margin and restoration type, the laboratory or CAD-CAM builds to that selection, a try-in verifies fit before delivery, and the restoration is delivered. The connection, the code and the component set exist to get each step right; this is the order they run in.

• Healing abutment shapes the emergence profile during soft-tissue healing
• Impression or scan records the implant position for the laboratory
• Abutment selection follows tissue height, restorative margin, engaging/non-engaging need and restoration type
• Laboratory or CAD-CAM builds the restoration on the selected abutment or Ti base
• Try-in allows verification of fit, proximal contacts, occlusion, emergence profile and aesthetics as applicable before final delivery
• Final restoration is delivered according to the applicable restorative protocol, and the components/article codes used are documented in the patient record
