Straumann® IMPLANTS

Tissue level implant

Straumann® implants are made of grade 4 titanium and a parallel implant body with outside threads. A machined collar of 2.8mm (Standard) or 1.8mm (Standard Plus) separates the implant/abutment interface from the surface treated implant body portion. Surface roughening is achieved through large grit sand-blasting with corundum particles followed by acid etching, commonly referred to as SLA® surface. A surface enhancement called SLActive® is an option available in addition to the SLA® surface treatment. The SLActive® surface has less surface tension and increases hydrophilic properties (wetability) intended to attract blood cells. SLActive® treated implants are stored and shipped in a vial filled with an isotonic (salt water) liquid to preserve the reduced surface tension qualities of the implant.
The implant/abutment indexing feature is either machined as a external hex or an internal octagon. External hex implants referred to as narrow neck implant (NN) are only available with a 3.3mm body diameter and a 3.5mm implant/abutment platform as Standard Plus (1.8mm machined neck) in four lengths (8, 10, 12, 14mm). Internal octagon implants are further divided in to two implant/abutment platform diameters of 4.8mm and 6.5mm. 4.8mm platform implants are called regular neck (RN) and are offered with implant body diameters of 3.3, 4.1 and 4.8mm in lengths of 6, 8, 10, 12, 14 and 16mm. 6.5mm platform implants are referred to as wide neck implants (WN) and available in one implant body diameter of 4.8mm in four possible lengths of 6, 8, 10 and 12mm.

Tapered effect implant

Tapered effect implants are a sub category of tissue level implants with similar features as tissue level implants. Two platform diameter (4.8, 6.5mm) internal octagon implants in lengths of 8, 10, 12 and 14mm with a 1.8mm (Standard Plus) machined neck) comprise the tapered effect implant offering. 4.8mm platform (RN) diameter implants are machined in two (3.3, 4.1mm) body diameters and 6.5mm platform (WN) diameter implants are available in only one (4.8mm) body diameter. The distinguishing signature feature of tapered effect implants is the flared out implant body at the top third of the implant. This flare is surface treated and the external threads are carried almost to the beginning of the machined surface of the neck, effectively increasing the number of threads on the implant body.

Bone level implant

Bone level implants are machined out of grade four titanium with a parallel body geometry and outside threads, available in two (3.3, 4.1mm) implant/abutment platform diameters. The 3.3mm platform is called "Narrow Connection" (NC) and the 4.1mm platform is referred to as "Regular Connection" (RC). Narrow connection implants are only offered with a 3.3 implant body diameter whereas the regular connection implant is available with a 4.1mm implant body diameter and a 4.8mm implant body diameter. Four lengths (8, 10, 12, 14mm) for all three body diameters are offered. The implant/abutment connection feature differs from tissue level and tapered effect implants and is not compatible with either one. A quadrigon (square) is the signature indexing feature of bone level implants, called CrossFit™. Bone level implants do not have a machined collar and the surface roughening is carried all the way to the implant/abutment connection. Both, SLA® and SLActive® surface treatments are available for bone level implants.
