Introduction to Implanova® Prosthetic System
a) The entire Implanova® prosthetic system uses the exact same screw type. The length of the screw head varies depending on the indication. All final abutment/restorations must be torqued to 20Ncm using an Implanova® prosthetic torque wrench. Please note that for the final restoration, the screw/abutment must be re-torqued to 20Ncm at least 10mins after the initial torqueing. If any preparations is made on the final abutment/restoration the screw/abutment must be torqued again. A single ISO hex driver is used for all prosthetic parts.
b) All Implanova abutments can be modified for suitable height and margin position by a carbide bur or diamond abrasive in a high speed hand piece with copious water. Final height should not be less than 4mm to secure adequate retention of crowns. The margin can be dropped down up to 1mm without reduction of diameter.
c) All Implanova® abutments utilize the conical, 11° tapered body design to ensure tight, uniform sealing with the internal surfaces of the implant. The abutment can be placed either at the time of surgical placement of the implant fixture if initial stability is sufficient or at a later date after the implant is integrated. As an alternative, a healing cap can be placed at the time of implant placement and can be replaced with the appropriate abutment after implant integration.
d) All Implanova® abutment components are made up of Grade 23 Titanium alloy (Ti-6Al-4V ELI) per ASTM F136.
e) Implanova medium height abutments are typically suitable for subcrestal placed implants. Short abutments are for crestal placed implants.
f) Implanova abutments that are designated as unibutments are those that do not have any platform on themselves and the emergence profile is created by the restoration.
g) Implanova® abutments come in seven forms. Straight abutments come in solid, one-piece or two-piece Contoured Shoulder abutments. Solid abutments have an integrated external thread that is designed to be directly fastened into the Implanova® implant fixture without the need of an additional screw. All Implanova® Angled unibutments and Contoured Shoulder abutments attach to the Implanova® bone level implant fixture using a single size, universal abutment screw. All Implanova® abutments are compatible with and fit all Implanova® implant sizes.
Note: Angled abutments should not be used with 3mm implants. This includes TiTACHTM abutments and angled FRIDGE® unibutments.
Angled Universal Height Unibutments
Angled Universal Height Unibutments are used to correct implant angulation up to 20◦. The restoration can start from the vertical part up to the screw access. The tip of the unibutment can be shortened as necessary with a carbide bur in high speed with copious amount of water. The minimal length of unibutment to retain a restoration is 4mm. These unibutments are suitable for crestal, subcrestal and way sub-crestal placed implants. They are ideal for “screwmentation” technique.
Angled Platform Prepable Abutments
Angled Platform Prepable abutments are for restoration of implants at 15 or 20 degree angles and incase of upper teeth when the implant is typically placed in the lingual direction compared to the axis of the desired crown.
