Nankali Post and Core System

The "Nankali post-system" or "Nankali post and core system" is a post-core, which is used in prosthodontology and or dental restoration in dentistry. This post consist of a single parallel smooth or serrated post and core which have an additional circle ring around it.

The Nankali-post was designed in 1997 by Dr. Ali Nankali in the National Medical University at the Orthopedic and Implant Stomatology Department, which (October 1999) became a part of Dr. Ali Nankali dissertation, verified by Scientific Board of National Medical University (O.O. Bogomolets).

In 1999 it was requested for the patent (УДК; 616.314-76-77:616.314.11-74:678.029.46:612.311) and became a part of research of the Orthopedic and Implant Stomatology Department of the National Medical University. This new modified post-core was under clinical study till 2004 and then attested by the Dental Scientific Board of the Ukraine.

Schematically a prepared tooth for Nankali-Post and Core System.

During four years observation (2000-2004 / National Medical University in Kiev), the number of reported complication from patient, whom were treated with the Nankali-post and core was none.

The additional single-circle ring increases the contact surface area between the core and involved hard tissue of tooth significantly. Increased contact surface area raises the level of force between to objects (remained hard tissue of tooth and post-core) followed by declining the number of fails in treatment.

General indications for Nankali-post system

The main general indications are:

1- Badly broken down teeth, 2- Trauma, 3- Tooth wear (erosion), 4- Hypoplastic conditions, 5- As part of another restoration, 6- combined indication, 7- Non-vital teeth, 8- ...

Advantages

The majority of the advantages of the Nankali-post System are the same as other post and core systems; however, there are some additional issues which make it different such as:

1- increasing the contact surface between the hard tissue of tooth and post and core,

2- minimum required preparation of the hard tissue,

3- and declining the number of difficulties at the time of tooth preparation and most importantly suitable for treatment of those teeth, in which there is a difficulty to dip in the root canal more than 50% of root length , and therefore they had to be extracted before.

The Nankali-post and core can be used for treating either single or multi-roots teeth and also in combination with other type of prosthetics.

The insertion ring increases the level of fixation, distribute equally masticatory pressure and provide appropriate condition for prosthetics.

The Nankali-post system is also recommended

for using bridges, crown or other types of dental

prosthetics, if a post core is required for

treatment .

 

Disadvantages

There are some issues, which can make some

difficulties to use the Nankali-post system.

1- Exact casting ( an exact cast post-core is

required to get the highest result, particularly,

when the depth of preparated canal is less

than 50% of the root length),

2- Specific bur is required,

3- ↑ plaque accumulation and changes in

composition, 4- Damage to soft tissues and

remaining teeth, due to either poor debtor

design or lack of patient care.
