CHAPTER 11 Root Form Implant Surgery: Proprietary II


The BioHorizons implant system consists of six styles of titanium alloy implants. These implants, which are threaded (reverse buttress threads), have either resorbable blast texturing (RBT) or a hydroxyapatite (HA) surface coating. The Tapered Internal design also has the proprietary Laser-Lok microchannels. The microchannels are a series of 8- and 12-μm grooves engineered onto the collar of the Internal implants, which come with an abutment and its retaining screw and a healing cover screw. The other implants have a polished collar. All of the implants have a lifetime unconditional restoration-to-implant warranty (Fig. 11-1, A).


Since 1985, Bicon implants have been promoted as the short implant of choice for the anatomically challenged areas where there is non-optimal alveolar height present in proximity to the inferior alveolar canal or the maxillary sinus. Implants are available with a grit blasted acid etched surface known as Inegra-Ti or with a calcium phosphate treatment (HA) known as Integra-CP.

In accordance with the manufacturer’s instructions for using a Bicon implant, initial cortical perforation is made with a 2.0-mm pilot drill with external irrigation to a depth 2.0 – 3.0-mm deeper than chosen implant (when practical) (Figure 11-2, A). Widening of the osteotomy is performed with sequentially larger reamers beginning with a 2.5-mm diameter and ending with the diameter of the intended implant (Figure 11-2, B). Reamers have horizontal markings at 6.0, 8.0, 11 and 14 mm, whereas older reamers may have different markings. It is imperative that the depth indicators on the latch reamers are known before surgery. No assumptions should be made about the height of the first marking on any latch reamer. If there is any doubt about the markings on any drill or reamer, take a measurement before using the reamer. Bone may be harvested from within the flutes of the reamers as no irrigation is utilized.

The Star/Vent implant is a single-stage, one-piece, titanium plasma spray (TPS) screw implant that allows immediate loading. It is available in diameters of 3.3 and 4 mm and lengths of 8, 11, 14, and 17 mm.

The Star/Vent implant has the StarimageLock internal hex screw and a press-fit cylinder in non-coated, restorable blast media–surface roughening treatment (RBM), TPS, or HA coated. Abutments are straight or 15 or 25 degrees. The implants are available in various diameters (3.3, 3.8, 4, 5, and 6 mm) and lengths (8, 10, 11, 13, 14, and 15 mm).

The external hex system in screw and press-fit cylinder shapes also is available. The different surfaces include RBM, surface roughening for noncoated implants, HA, and TPS. The HA and TPS coatings are available in all sizes.

For the osteotomy for the Star/Vent, the 3-mm generic spade drill is used to its planned depth.
