Indications for Use
The Ball Abutment Systems are used for implant retained mucosa-supported restorations, such as overdentures where the patient is fully edentulous in the arch to be restored. There are two types of Ball Abutment system, internal and external type, and the ball abutment technique is used on Ball Abutment System implants in the maxilla or mandible.
Device Story
Ball Abutment System consists of dental implant abutments designed to connect fixtures to overdentures. Available in internal and external connection types; internal type features 11° taper for fixture contact; external type utilizes hex interface. Both types feature 2.25mm diameter ball head for connection to Dalbo Plus overdenture attachments. Available in various diameters (2.85mm, 3.10mm, 5.00mm, 6.00mm) and gingival heights (2.0mm, 4.0mm, 6.0mm). Used by dental clinicians to support prosthetic restorations in edentulous patients. Device provides mechanical interface between endosseous implant and removable overdenture, facilitating patient restoration.
Clinical Evidence
Bench testing only. No clinical data provided.
Technological Characteristics
Materials: Ti-6AI-4V ELI and stainless steel per ASTM/ISO standards. Connection types: Internal (11° taper) and External (hex). Ball head diameter: 2.25mm. Dimensions: 2.85mm-6.00mm diameters; 2.0mm-6.0mm gingival heights. Mechanical coupling to Dalbo Plus attachments.
Indications for Use
Indicated for fully edentulous patients requiring implant-retained, mucosa-supported restorations (overdentures) in the maxilla or mandible.
Regulatory Classification
Identification
An endosseous dental implant abutment is a premanufactured prosthetic component directly connected to the endosseous dental implant and is intended for use as an aid in prosthetic rehabilitation.
Special Controls
*Classification.* Class II (special controls). The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control.

#### 6. Purpose:
The purpose of this 510(k) is to include the components that are to be used with the internal external method in joining the fixtures and prosthetics to the prior 510(k) submission for the Ball Abutment System.
## 7. Device Description:
The abutments with the following diameters are available in sizes of 2.85mm, 3.10mm, 5.00mm, and 6.00mm. The male part for each diameter is available in gingival heights of 2.0mm, 4.0mm, and 6.0mm, and the ball head diameter is 2.25mm. There are a total of 15 different size ball abutment systems being offered by Megagen.
## External type
The lower part of the Ball Abutment is composed of internal circle so that the external hex of fixture can be inserted. It can combine with screw to be fixed. The top part of the abutment is ball type, and the ball head diameter is 2.25mm, and it is designed to be able to connect with Dalbo Plus which is fixed on overdenture.
### Internal type
This type of abutment is inserted and combined with fixture in order to support the overdenture. The sides of lower part of the abutment have been constructed with an 11° so that they can contact with upper part of the inner fixture. The top part of the abutment is designed as a ball type, and the ball head diameter is 2.25mm. This type of design enables to be connected with Dalbo Plus, overdenture.
#### 8. Indication for use
The Ball Abutment Systems are used for implant retained mucosa-supported restorations, such as overdentures where the patient is fully edentulous in the arch to be restored. There are two types of Ball Abutment system, internal and external type, and the ball abutment technique is used on Ball Abutment System implants in the maxille or mandible.
### 9. Performance Standards:
FDA has not established a performance standard applicable to ball abutment system. The materials in the Ball Abutment Systems meet applicable standards.
{2}------------------------------------------------
#### 10. Materials:
These devices are manufactured from Ti-6AI-4V ELI and stainless steel per ASTM and ISO standards.
### 11. Packing / Labeling / Product Information:
Ball Abutment System follows the guidance of the 21 CFR 872.3630.
## 12. Substantial Equivalence Comparison
Ball Abutment System is substantially equivalent to Osstem Implant Co., Ltd, Altatec GmbH (K063861, K051636). Testing and other comparisons have established that the subject of Ball Abutment System is substantially equivalent in design, materials, indications and intended use, packaging, labeling, and performance to other predicate devices of the type currently marketed in the U.S. This device is substantially equivalent to a predicate device when the device has the same intended use and the same technological characteristics as the previously cleared predicate device, and it can be demonstrated that the device is as safe and effective as the predicate device, and that the new device does not raise different questions regarding safety and effectiveness as compared to the predicate device. It has been shown in this 510(k) submission that the differences between the Ball Abutment System and the predicate devices do not raise any questions regarding its safety and effectiveness. The Ball Abutment system, as designed and manufactured, is as safe and effective as the predicate devices and therefore is determined to be substantially equivalent to the referenced predicate devices.
#### 13. Review:
The Ball Abutment has the same device characteristics as the predicate device. Its materials, dimensions, and intended use are similar to devices currently marketed worldwide.
The Ball Abutment has been subjected to extensive safety, performance, and product validations prior to release. Safety tests have been performed to ensure the devices comply to applicable industry and US regulations.
## 14. Conclusions:
:
In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807, and based on the information provided in this premarket notification Osstem Implant Co., Ltd, Altatec GmbH concludes that the ball abutment is safe and effective and substantially equivalent to predicate devices as described herein.
