IMPLANT CLINICAL POSITION TRANSFER TO DENTAL LAB
A2 CLASSIC ABUTMENTS
INDICATIONS for use : crowns and bridges with cement retention
- are the most versatile and multifunctional suprastructures designed for crown and bridge fabrication.
- have an integrated screw to increase patient safety against aspiration: there is no need for placement and cannot fall out.
- offer a wide range of gingiva heights (S, M and L) an inclination angles (0° and 7.5°)
- can be customized to adapt their shape to a specific clinical situation.
- with an index can be easily seated in one of six positions.
- without an index, use a transfer key for proper positioning.
CAUTION: For reliable cement retention, the shortening should not be less than 4 mm.
A2 TITANIUM BASES
INDICATIONS for use: single crowns with screw retention
- are simple and reliable suprastructures ideally for screw-fixed crowns.
- have an integrated screw to increase patient safety against aspiration: there is no need for placement and cannot fall out.
- offer a wide range heights of gingiva transition (S, M, L and XL) and supra-gingival parts (4.0 mm and 6.0 mm).
- can be downloaded from our website (A2implant.com) to create crowns in CAD programs.
- with an index can be easily seated in one of six positions.
- without an index, use a transfer key for proper positioning.
CAUTION: The manufacturing of bridges on A2 Titanium bases with screw fixation from the implant level is not recommended because of the risk of incomplete cone fit.
A2 PRE-MILL ABUTMENTS
INDICATIONS for use: crowns and bridges with cement or screw retention
- consist of one part that is precision-milled in the factory and one part that is milled in the dental laboratory to create a custom abutment.
- have an integrated screw to increase patient safety against aspiration: there is no need for placement and cannot fall out.
- can be downloaded from our website (A2implant.com) to design with CAD programs.
- provide sufficient initial dimension to create different gingival depths and angles of inclination.
- can be adapted for the following holders: Medentica / Arum / Zirkonzahn
- with an index can be easily seated in one of six positions.
- without an index, use a transfer key for proper positioning.
CAUTION: For reliable cement retention, the shortening should not be less than 4 mm.
A2 MULTIUNIT ABUTMENTS
INDICATIONS for use: bridges with screw retention
- are designed for screw-retained bridges.
- offer a wide range of gingiva heights (S, M and L) an inclination angles (0°, 7.5° and 30°).
- are solid when straight, angled with integrated screw.
- can be downloaded from our website (A2implant.com) to create bridges in CAD programs.
- allow the use of A2 Titanium Caps, which provide a passive fit of the bridge and prevent the zirconia from cracking during fixation.
CAUTION: The fabrication of single crowns is contraindicated.
A2 LOCK ABUTMENTS
INDICATIONS for use: implant-retained tissue supported overdentures
- offer a wide range of gingiva heights (2 mm, 3 mm, 4mm, 5mm and 6 mm) an inclination angles (0° and 7.5°)
- have an universal upper cylindrical part
- are solid when straight, angled with integrated screw.
- use a titanium matrix with a nylon insert to anchor removable full dentures.
- with attached matrix require a minimum of 7.5 mm vertical space from the implant shoulder (2 mm gingival height + 3.5 mm attachment and 2 mm denture acrylic).
- with attached matrix require a minimum of 9.5 mm of space in the horizontal plane (5.5 mm matrix ø + 2.0 mm each of oral and buccal denture acrylic).
A2 PROSTHETIC INSTRUMENTS
- Cover Screws, Healing, Impression and Scan Abutments have a 7.0 mm hex slot. Use a manual 1.0 mm hex Screwdriver without excessive effort.
- Classic Abutments, Titanium bases and milled Blanks have a hex slot located in the cap of the integrated screw. Use a 1.0 mm hex Screwdriver and a prosthetic ratchet wrench to apply 15 Ncm of torque.
- Strait Multiunit Abutments have a 1.8 mm hex slot. Use a 1.8 mm hex Screwdriver and prosthetic ratchet wrench to apply 25 Ncm of torque.
- Angled Multi-Unit Abutments consist of two parts: an angled base with a 1.0 mm hex and a platform with a 1.8 mm hex. Attach the angled base using a 1.0 mm hex Screwdriver with a torque of 15 Ncm, then attach the multi-unit platform using a 1.8 mm hex Screwdriver with a torque of 25 Ncm, applied by the prosthetic ratchet.
- Strait Lock Abutments have a 1.8 triangular slot. Use a 1.8 mm triangular Screwdriver and prosthetic ratchet wrench to apply 25 Ncm of torque.
- Angular Lock Abutments consist of two parts: an angled base with a 1.0 mm hex, and a platform with a 1.8 mm triangular slot. Install the corner base with a 1.0 mm hex Screwdriver with a torque 15 Ncm, then fix the platform with a triangular Screwdriver with a torque of 25 Ncm, applied by the prosthetic ratchet.
