For hard bone(type I bone or harder bone) , dentist find it is very hard to screw Dynamix or Classix implants in the bone. And when the torque goes up to 50N or higher, the patient will feel bad about the process of the implantation. And sometimes, they e

In the hard bone it is better to use Classix implants with the hard bone protocol. It is means that the dentists should go with the next drill for final placement. I would recommend to deepen the preparation with 0.5 mm as well. In addition, we are very near to provide a dedicated drills for hard bone cases for Ø3.8, Ø4.2 and Ø5.0mm implants.

About platform shifting, some doctor think the ring on the top of the implant is too small, and at the same time, the abutment's dia is 3.75mm while the implant dia is almost 3.75mm. and so these could not have the function of platform shifting to help os

The platform shifting starts from 4.2 mm. On the narrower implants like 3.8, 3.3 the abutment and the implants are in the same lateral level. The conical connection system offers bigger platform shifting in all diameters.

For dynamix, we have the design of reverse conical head. What is this function and advantage? Is it helpful to the platform shifting?

The reverse head of dynamic is very light and it's starts from diameter 4.2 and more. The purpose of it is to allow better bone adaptation and bone volume around the implants in the upper jaw.

About surface modification of Cortex Implants, do we have any research paper showing that our surface is better than other implants, and the features and advantage of our surface?

We have SEM analyses which can demonstrate the quality of Cortex implants. Please find enclosed, typical SEM/XPS report for our implants.

In the surgical manual, "If the clinical situation allows, adjust the final position of the implant so that any one of the six internal connection lobes faces the buccal or facial aspect" is this step mostly used for the esthetic considering?

This step is recommended for the placement of angulated abutment or anatomic abutments (where there is a different between the Bucal and Lingual heights). Their inclination starts from the flat hexagonal position.

As to stopper kit, why do we only have the size of 2.0mm and 2.8mm? many brands have all the size of the drill.

Most of the clinicians not use the stoppers on widower drills because the enlarging the osteotomy and not drilling it further.

What is the torque when dentist drilling a hole in the bone?

Usually implant motors are programmed for it, but it should be around 20 N

As to the hex connection, is there a gap between the abutment and the implant after the abutment is secured on the implant?

If the abutment secured with torque of 30 N , than the gap is safe. Please see attached compatibility report.

For the anatomical abutment, Some dentist think the design of our abutment is hard for soft tissue to heal as there is no space for them to grow. This is correct? How can I denfend them?

There are different anatomical abutments with the collar height between 1 and 4 mm.

What is the reason of the abutment lose after restoration 6 months ?

The reason for loosening of the screw can be unbalanced occlusion with traumatic contact or weak tightening of the screw .it should be 35 Ncm. If it repeats again after correction of all the points i wrote than he can put a small drop of Fugi cement or Duraly on the tip of the screw.
