Clinical Guidelines for Hiossen EK Implant System

Guidelines for Clinical Selection, Repair Process, and Solutions of Hiossen EK Implant System

In the field of oral implantation, the connection design of the implant, the universality of the repair components, and the convenience of operation directly affect the clinical treatment effect and long-term stability. The EK Implant System, launched by Hiossen (a brand under the Aoshitai Group), provides a complete solution for clinical practice, from single tooth loss to full mouth edentulous jaw restoration, thanks to its innovative design of "single platform connection, thickened inner wall, 15 ° Mohs taper, and anti rotation locking buckle". However, faced with a wide variety of repair abutments, transfer rods, scanning bodies, and digital processes, doctors and technicians often need a systematic guide from selection to operation.

This article is based on the EK product catalog and combines common clinical scenarios to systematically review the technical characteristics, repair component classification, digital impression process, attachment selection, and key points for replacing old implant systems of EK implant systems. It helps readers quickly establish a knowledge system of EK systems and improve repair efficiency and success rate.

Core technical characteristics of EK implant system

1.1 One Connection

All diameters of implants in the EK system (from Ø 3.5 to Ø 7.0) use identical internal connection structures (including internal hexagon, Mohs taper, and anti rotation groove). This means:

The repair base is completely universal, with simple inventory management and no need to prepare different repair parts for different diameters.

Flexible clinical operation: Even if the diameter of the implant cannot be determined before surgery, the repair abutment can still be selected in advance.

Reducing errors: Avoiding mismatches between the abutment and the implant caused by different connection structures.

1.2 Thickened inner wall and fine diameter screws

The EK system uses small-diameter fixing screws to increase the thickness of the inner wall of the implant. This design brings:

Stronger resistance to mechanical fatigue and reduced risk of screw breakage.

Better stress distribution: Thicker inner walls can absorb some biting force, reducing bone resorption in the neck of the implant.

1.3 Deepened implant abutment connection depth

The connection depth is deeper than traditional designs, effectively dispersing chewing pressure, reducing screw stress, and significantly reducing the probability of screw loosening. Internal testing shows that compared to the traditional 11 ° Mohs taper, a 15 ° taper reduces the risk of screw loosening by 33%.

1.4 15 ° Mohs taper and anti rotation locking buckle

15 ° Mohs taper: Provides strong cold welding effect, even if the screw is slightly loose, the base will not immediately fall off, while reducing the sink down effect.

Three anti rotation locking buckles: Before tightening the screws, the abutment can be firmly locked inside the implant to prevent displacement caused by gum elasticity, making it convenient for mold removal and tooth insertion.

1.5 Surface Treatment

The EK implant adopts a low crystalline nano hydroxyapatite (HA) coating (SA surface) to promote early osseointegration while maintaining long-term stability. Thread design: Small threads on the neck increase the initial stability of cancellous bone; The main body has double threads and cutting blades to improve self tapping ability. It is recommended to implant a torque of ≤ 40 Ncm.

Key points for classification and selection of repair components

The EK system provides a variety of repair components, which can be classified into the following categories based on the type of repair:

2.1 Temporary repair components

Component Model Example Usage Precautions

Healing abutment EKHA403 (H3.0, D4.0) to EKHA709 formed gingival cuff gingival height 0.5mm higher than Ø 3.5 implant, soft tissue thickness should be considered when selecting

Cover the screw and select the buried healing method according to the height H. When sealing the upper end of the implant, manually tighten it with a 1.2 hex wrench

Temporary base EKTA series temporary crown bridge can be used in conjunction with laboratory screws

Selection reference: The gingival height (G/H) ranges from 1.0 to 5.0mm, and the corresponding height of the healing abutment or transfer rod should be selected after measuring the gingival penetration depth.

2.2 Mold taking component (transfer rod)

EK supports two types of impression methods: Open Tray and Closed Tray

Type Component Model Code Characteristics

Open Tray mold transfer body+guide screw (Hex/Non Hex) EKP4011+EKPGP100 is precise and suitable for multiple implants, requiring specialized long guide screws

Closed Tray Transfer Bodies (Hex/Non Hex) EKT4011/EKT4011N are easy to operate and suitable for single or ample gaps

Window type extended mold transfer body L16 EKP4016+EKPGP150 deep implantation or thick gingiva

Hex vs Non Hex: The Hex type has a hexagonal anti rotation structure at the bottom, which can be accurately positioned after stamping; The Non Hex type is a smooth cylinder, often used in situations with large angular deviations. Both need to be tightened with a 1.2 hex wrench.
