Straight Solid Abutments are single piece, solid abutments that are designed to be used in parallelism with a placed implant fixture. Straight abutments are available in 3 diameters – Narrow (4.1mm), Standard (4.8mm), and Wide (6.5mm). They are selected based on the available space between the two adjacent teeth and the type of restoration to be used. For each abutment diameter, there are 3 different neck lengths available – Short (1.7mm), Medium (3.1mm), and Long (4.6mm) – which are designed to be used with bone-level implant placement levels, respectively. Due to a thick, meaty abutment center, all Straight abutments are by the practitioner for specific height and shoulder positions. Straight abutments feature a single, hexagonal socket size that is universal to the Implanova® implant system and compatible with the Pick ‘Em Up™ Hex Drivers. Implanova® Straight abutments should be placed manually or at 20 rpm with a torque of 20 Ncm.
Note: Solid abutments are ideal to be used in two or more adjacent implants. In this case, the chance of screw loosening would be practically zero. Solid abutments are not recommended as single unit restorations as occlusal forces may loosen abutment-restoration unit.
Caution: Once the abutment is screwed on the implant, it may become impossible to unscrew the abutment without unscrewing the implant with even as low as 5 N-cm force, unless the implant is integrated (6 weeks out). Therefore, if you are placing the abutment at the time of initial placement, make sure the implant is secured (larger than 30 N-cm insertion torque) and you have the correct diameter and neck length for abutment selection.
