Straumann® ABUTMENTS

Tissue level and tapered effect implant

Fig. 1

Narrow neck implant/abutment platform (NN, 3.5mm) abutments (Fig.1) are all indexed to the external octagon of the narrow neck implant and do not include the fixation screw with the exception of temporary abutments. The fixation screw (catalog # 049.177) needs to be purchased separately with each abutment in the NN abutment product line up.

A single straight titanium abutment with a 2mm collar and two pre angled (15°, 20°) abutments with a sloping collar are available in addition to a standard gold/plastic UCLA (Ceramicor®, Cendres & Métaux SA) to fabricate custom abutments. The angulation of the angled abutments is queued to one of the flat sides of the octagon indexing feature and a special all gold (Esteticor® Cosmor H, Cendres & Métaux SA, CTE 13.8-14) abutment for direct veneering with porcelain is also part of the product offering.

Regular neck (RN, 4.8mm) implant abutments are available in two general categories. Non indexed solid abutments popularized industry wide through Straumann® and more traditional titanium abutments. Solid abutments are machined as a single entity combining the abutment and the abutment screw in to a monolithic element. Solid abutments do not engage the anti rotational feature (internal octagon) of the implant due to the one piece design.

Originally conceptualized to be installed by the surgeon to reduce tooling requirements and simplify the impression technique for the restorative dentist. A new impression technique was developed by Straumann®, employing simple, snap on plastic impression copings, referred to as abutment level impression. Three color coded solid abutments (Fig.2, top row) are offered for RN platform implants in three heights (4mm yellow, 5.5mm gray, 7mm blue). The abutments are machined with a flat side and a groove opposite the flat side and require a special driver (catalog # 046.067) to torque the abutment on to the implant.

Fig. 4

Traditional abutments (synOcta) for RN implants are designed with a "trapped" screw and the screw can not be replaced. One straight (Fig.3, left) and eight pre angled abutments are available. Two angulations (Fig.3, 15°, 20°) in two heights (5.7mm, 6.7mm) are produced with a type "A" and a type "B" angulation in relation to the indexing octagon. Type "A" (Fig.4, bottom) has a angulation in correlation to one of the flat sides of the indexing octagon and type "B" (Fig.4, top) has a angulation in conjunction with one of the vertices (corner) of the indexing octagon.
SynOcta gold abutments (Fig.5, left, UCLA, Ceramicor®, Cendres & Métaux SA, 048.642) are available as an indexed version only and include a removable and replaceable final fixation screw (catalog # 048.357).

Fig. 5

Wide neck (WN, 6.5mm) implant abutments are also available in two general categories. Non indexed solid abutments as discussed in the above RN section and more traditional titanium abutments. Two color coded solid abutments (Fig.2, bottom row) are offered for WN platform implants in two heights (4mm green, 5.5mm brown). The abutments are machined with a flat side and a groove opposite the flat side and require a Torx (SCS) driver (catalog # 046.401) to torque the abutment on to the implant.

Fig. 6

Traditional abutments (synOcta) for WN implants are designed with a "trapped" screw and the screw can not be replaced. One straight (Fig.6, left) and two pre angled abutments (Fig.6, middle and right) are available. One angulation (15°) in one height (5.5mm)  produced with a type "A" and a type "B" angulation in relation to the indexing octagon. Type "A" (Fig.4, bottom) has a angulation in correlation to one of the flat sides of the indexing octagon and type "B" (Fig.4, top) has a angulation in conjunction with one of the vertices (corner) of the indexing octagon. SynOcta gold abutments (Fig.5, right, UCLA, Ceramicor®, Cendres & Métaux SA, 048.644) are available as a indexed version only and include a removable and replaceable final fixation screw (catalog # 048.357).

Bone level implant

Fig. 7

Narrow connection (NC) Implant/abutment platform diameter abutments can be categorized in to four groups, anatomic, gold (UCLA), ceramic and "cementable". Anatomic, gold and ceramic abutments are intended to be selected and modified extra orally on a master model after a fixture level impression (direct, indirect).

"Cementable" abutments (Fig.7) are envisioned to be installed on to the implant and impressed with the abutment level impression technique, much like solid abutments for tissue level implants.

Fig. 8

Cementable abutments are not cemented in to the implant as the name might suggest but screwed on to the implant like other abutments for bone level implants. Twelve different color coded "cementable" abutment versions are  produced, combining two different emergence profiles (Fig.7, left) 3.5mm blue, 5.0mm yellow) and three collar heights (Fig.7, bottom row 1, 2, 3mm) with two abutment portion heights (Fig.7, right 4mm, 5.5mm). A color band etched on to the coronal portion of the abutment indicates the abutment portion height (4mm black, 5.5mm white) (chart).

Anatomic titanium abutments (Fig.8) are machined as a straight and a angled (15°) version. Each abutment is available in two collar heights (2mm, 3.5mm) and the angulation of the angled abutment is machined in relation to the vertex of the indexing quadrigon (square).

Fig. 10

Gold abutments (Fig.10, UCLA) are fabricated with a machined gold indexing interface and a nylon tube processed on to the gold portion. Only a indexed version is available to manufacture custom abutments or single screw retained crowns. Screws are included with each abutment purchased as a kit. The screws are color coded purple for easy platform group identification and are not universally interchangeable from abutment type to abutment type or platform group to platform group. Each titanium abutment is marked with the capital letters NC.

Regular connection (RC) platform diameter abutments can be categorized in to four groups, anatomic, gold (UCLA), ceramic and "cementable". Anatomic, gold and ceramic abutments are intended to be selected and modified extraorally on a master model after a fixture level impression (direct, indirect). "Cementable" abutments are envisaged to be installed on to the implant and impressed with the abutment level impression technique, much like solid abutments for tissue level implants.

Fig. 12

Cementable abutments are not cemented in to the implant as the name might suggest but screwed on to the implant like other abutments for bone level implants. Twelve different color coded "cementable" abutment versions are produced, combining two different emergence profiles (Fig.11, left 5.0mm gray, 6.5mm brown) and three collar heights (Fig.11, bottom row 1, 2, 3mm) with two abutment portion heights (Fig.11, right, 4mm, 5.5mm). A color band etched on to the coronal portion of the abutment indicates the abutment portion height (4mm black, 5.5mm white) (chart).

Fig. 13

Anatomic titanium abutments (Fig.12) are machined as a straight and a angled (15°) version. Each abutment is available in two collar heights (2mm, 3.5mm) and the angulation of the angled abutment is machined in relation to the flat side of the indexing quadrigon (square). Through and through indexed ceramic (IPS e.max®) abutments (Fig.13) are available in two shades (MO 0, MO 1), two angulations (0°, 15°) and two collar heights (2mm, 3.5mm).

Fig. 14

Gold abutments (Fig.14, UCLA, Ceramicor®, Cendres & Métaux SA) are fabricated with a machined gold indexing interface and a nylon tube processed on to the gold portion. Indexed and non indexed versions are available to manufacture custom abutments, single screw retained crowns, screw retained bridges and bar substructures. Screws are included with each abutment purchased as a kit. The screws are color coded purple for easy platform group identification and are not universally interchangeable from abutment type to abutment type or platform group to platform group. Each titanium abutment is marked with the capital letters RC.
