Abstract of
Radiographic analysis of the variation in the anatomical configuration of the
nasopalatine canal
The main aim of this study is to analyze radiographic
variation in the anatomical configuration of the nasopalatine canal. This will discuss
anatomical and morphology of the nasopalatine canal. This will be analyzed on
the cone beam computed tomographic images. According to these images the
results will be compared properly. This results will show the comprehensive
knowledge on the anatomical variation. Moreover, this knowledge is also
mandatory in the skeletal surgery present in the anterior maxilla. It can be
noted that the surgical procedure of dental implantation is done through using
radiographic techniques. The main purpose of this study is to evaluate the
anatomy of nasopalatine canal present in the human body. For that case, CBCT
images of more than 300 patients will be evaluated for analyzing the
nasopalatine canal characteristics. It can be noted that there are some five
linear measurements will be analyzed properly. Then in the end apply some tests
on these measurement for obtaining original results of the system.
Introduction of
Radiographic analysis of the variation in the anatomical configuration of the
nasopalatine canal
It can be observed that there are different implant
procedures are considered for replacing the missing teeth. For that case,
dental implants are used by different dentists all over the world. Moreover,
through this they can easily restore the esthetic and functional need of the
prosthodontics measures. The next point is that it is not easy for the dentist
to implant teeth successfully. It is considered as a huge challenge for them. But
it can be noted that there are some critical factors through which it will
become easy to get success in any dental treatment. The next point is that
quality of bone and its regular shape is providing a regular space for the
implant fixtures. This shows that quality of bones are defining the future
stability and Osseo integration success of the operation. The next point is
that Maxillary anterior teeth are considered as extremely important. These
teeth are also important for trauma during childhood. Moreover, it is
considered as a huge tasks for the dentists for replacing these teeth. Due to
this problem esthetic, repairing function and phonetics are satisfied and considered
properly (Virdi, 2015).
The main reason is that Esthetic outcome is one of the most
important factor for the dentist during implant. It will also surpass this
function during the dental implants. The next point is that there is need a
safe distance between dental implants and anatomical landmarks. Through this
distance it will become easy to apply stable implant treatment. Furthermore,
nasopalatine canal is considered as a bony connection between the oral cavities
and nasal and it contains some neurovascular bundles (Thomas von Arx, 2016).
Materials and methods
of Radiographic analysis of the variation in the anatomical configuration of
the nasopalatine canal
This can be done through experimental method, for conducting
the experiment, there is need to take approval from the Ethical committee. Then
after this these patients are referred to the private Dent maxillofacial
radiology clinic made for the patients. In this clinic, the radiographic
technique CBCT will be applied. For that purpose pre-implant CBCT evaluation
will be analyzed properly according to this cross sectional study. For that case, there are number of patients
were enrolled and according to that only 300 were selected. This shows that
only 140 males and 160 females are meeting the criteria of exclusion-inclusion.
This criteria shows that the individuals with more than 18 age contain central
and maxillary incisors. There are also different criteria of exclusion include,
radiolucent lesion, impacted teeth, suspected NPC, pathology, anatomical area
of interest, bone graphs, cleft plate and related syndromes. If any person
contains such things then it will be included in this criteria. Then after
this, a written informed consent was taken from all patients participating in
the experiment (Panjnoush M, 2016).
Then after this, according to radiographic technique, all
CBCT images are obtained from all patients. Then after this all of these images
were converted into the resolution mode through the help of different scanners.
Such scanners must contain the value of kVp of 110 and also FOV of 8x8 cm.
furthermore, after this a proper coronal and sagittal cross sections were made
properly. For that case, the thickness of these intervals are set at 0.5 mm. All
of these images were observed by different researchers related to the field of
dentistry. Moreover, it is also analyzed under the supervision of the
experienced maxillofacial radiologist. After this, both anatomy and nasopalatine
canal dimension were analyzed properly. These measurements are made for
analyzing the dimension of the nasopalatine canal given in mm. This can be done
through the help pf sagittal CBCT and it is present as K1, K2, K3, K4 and K5.
This means that the K1 is showing the diameter of the nasal opening of the
canal. The K2 is considered as the diameter of the canal. On the other hand, K3
is the length of the canal and the vertical distance present between the oral
opening and nasal. The width of buccal bone plate is given by K4 and K5 is
considered as the width of the buccal bone plate that is present over the nasal
opening of the nasopalatine canal (Koppolu, Pathakota, &
Chappidi4, 2019).
Figure 1: Measured demission of the nasopalatine
canal
In the above figure, all connections are shown with complete
details. This shows that in the coronal CBCT cross section, there is NPC
anatomy and it was then classified in different groups. All of these groups are
made according to the classification of Bornstein. Moreover, this type of
classification also include type A. This type only contains only single canal.
On the other hand, in type B there are two parallel canals are present. Moreover,
according to type C, there is some variation with the one oral opening of the
nasopalatine canal. This can be explained with the help of figures.

canal
The above figure showing the complete detail about these
classification. Moreover, it is also known as anatomic classification of
nasopalatine canal morphology.
Figure 3: Radiographic image of these types
The above image is showing the radiographic images of these
types. Now for the statistical analysis, the SPSS software application is used
that will show one way ANOVA tests. After this, these tests are compared with
the dimensions present between the different participants. Moreover, another
test was used for comparing the frequency of the canal shape groups (FRIEDRICH, LAUMANN, ZRNC,
& ASSAF, 2015).
Results of Radiographic analysis of the variation
in the anatomical configuration of the nasopalatine canal
The results are shown according to the study criteria. It also
include more than 300 cases. It also shows that the age of these patients are
more than 18 years. According to these results more than 100 cases are excluded
due to some reasons. These reasons include, poor quality, artifacts, pathology
and other missing incisors. The results are showing the value of all variables
from K1 to K5. It is showing the highest value of K3 is about 21 and its main
standard deviation is also high. According to these results it is also showing
that the type C is considered as most prevalent type of NPC collected from
these patients. On the other hand, the type B is considered at least frequents.
Moreover, the value of K1 to K5 variables and also the percentage and
frequencies of different type of NPC is given in tables below.

Discussion of
Radiographic analysis of the variation in the anatomical configuration of the
nasopalatine canal
It can be noted that the Maxillary anterior teeth are
extremely important during childhood. The main reason is that they contain
outmost esthetic importance during smiling. Moreover, another fact is that the
angulation and location is responsible for determining the profiles of the
individual. Another fact is that such teeth are responsible for incising. On
the other hand, these teeth are also vulnerable to trauma because they are
present in the exposed location. They are also called as thin planar teeth. If
a person loss them permanently then there is a facility of surgical implants. Furthermore,
it is considered as the broadest accepted method for the rehabilitation of
tooth loss in anterior maxilla. On the other hand, one of the main drawback of
this procedure is that it contains some anatomic limitations. This is because
NPC is able to occupy more than 58% of the buccal bone plate width. This width
can easily support the implants. But for that there is a need of comprehensive
planning for implant treatment in anterior maxilla and it is also considered as
risky phenomenon. On the other hand, the next fact is that incaution operations
may damage this neurovascular content of the nasopalatine canal. Due to this
case, the person may face some harmful problems like anesthesia, failure of
Osseo integration and hemorrhage. But this problem can be solved easily through
the help of CBCT imaging and it is a radiographic technique. These images are
able to reveal the anatomic characteristics of the nasopalatine canal in a
proper way without any difficulty (Leila, Haghnegahdar,
& Keshtk, 2017).
Another fact is that this type of technology is increasing
at fast rate. Moreover it is also applied for pre-implants radiographic
evaluations. This whole technique is completely based on the cone-shaped x-ray
source. It also contains two dimensional detector. This detector is involved in
preparing data in a single rotation. The main advantage of this technology is
that the patient dose and time is decreased comprehensively. There are some
researchers that highlighted and evaluated the ridge configuration anterior
according to nasopalatine canal. The results are showing that as the concavity
depth and angle is high then bone height will be shorter in different patients.
Moreover, there is also need to remove these negative effects in the morphology
of the IC. On the other hand, another study is also showing the presence of
maxillary central incisors. It is also showing that the Y-shaped canals present
in the coronal section are present in high amount according to the current
study. These sequences and percentages of nasopalatine canal types is quite
similar to previous studies. It is also showing that the canal shapes are not
affected by race. Moreover, some researches also shows that the buccal bone
plate is majorly affected by gender. But the main fact is that characteristics
of measurements are different between these studies. There are also various
studies that are discussing the absence and presence of maxillary anterior
teeth on the buccal bone plate. The main reason behind this is that the width
of buccal bone is quite low (Khojastepour, Haghnegahdar,
& Keshtkar, 2017).
Conclusion of Radiographic analysis of the variation
in the anatomical configuration of the nasopalatine canal
Summing up all the discussion from above, it is concluded
that nasopalatine canal is showing a large variety in dimensions and
morphology. The next point is that it is not easy for the dentist to implant
teeth successfully. Moreover, it is considered as a huge tasks for the dentists
for replacing these teeth. Due to this problem esthetic, repairing function and
phonetics are satisfied and considered properly. This criteria shows that the
individuals with more than 18 age contain central and maxillary incisors. There
are also different criteria of exclusion include, radiolucent lesion, impacted
teeth, suspected NPC, pathology, anatomical area of interest, bone graphs,
cleft plate and related syndromes. This type only contains only single canal.
On the other hand, in type B there are two parallel canals
are present. The results are showing the value of all variables from K1 to K5.
It is showing the highest value of K3 is about 21 and its main standard
deviation is also high. This width can easily support the implants. But for
that there is a need of comprehensive planning for implant treatment in
anterior maxilla and it is also considered as risky phenomenon. These images
are able to reveal the anatomic characteristics of the nasopalatine canal in a
proper way without any difficulty. It is also showing that the Y-shaped canals
present in the coronal section are present in high amount according to the
current study.
