2. 1. Stability - Housing does not contact the fixture directly. - 3pcs of ceramic balls provide perfect retention.  Distributes masticatory force properly. (Currently the main topic  of prosthetic dentistry) - Ceramic ball durability is at least 50,000 insertions. - Male nylon part between housing and fixture provides retention by friction. Frequent insertion can damage retention function. -> In worst case, it is necessary to change male Nylon every 2~3months. -> Masticatory force is not distributed and may be cause of failure because of the force concentrated on the fixture. -It is not easy to find the correct insertion position and it may easily become detached from fixture.

3. 2. Compensation #25 C/T 40° 20° 10° In this case, it may not provide enough retention force. To obtain enough force, it may be necessary to replace the nylon male. It can apply unreasonable force to the fixture. In clinical terms, it is almost impossible to place the fixture at the correct angle.

4. 3. Aesthetics and convenience When denture width is narrow and if the metal color is black, it may visible after connecting with the housing and this is not recommended. EZ Lock is coated in a pink color, and therefore not visible. Available elimination range : 2.2mm 1.Convenient to arrange denture as it eliminates 2.2mm of housing wing, when the housing width of denture on which it will be placed is narrow, 2. Length of a wide housing wing is 6mm and a narrow one is 4mm. When the width is narrow for denture it is still possible to place it properly. * Housing size comparison Diameter : EZ 5.16mm Kerator 5.5mm Height : EZ 3.1mm Kerator 2.5mm

6. 5. Convenience + simplicity 6. Economic For the patient : Easy to find the correct position for denture insertion as the head shape of abutment is circular, and you can hear the sound of the connecting 3 ceramic balls when the denture is properly inserted. For the dentist : Easy to prepare prosthetics - Easy to insert abutment with carrier and find the fixture path - Carrier can be used as impression coping. Ceramic balls inside the housing ensure a long lasting retention force. (semi-permanent) Other products may need replacement of nylon male regularly. For Patient : No need to visit the clinic again after denture process. For Dentist : Saves time.
