Abstract
ABSTRACT
Background
There are no radiographic studies in Nepalese population for determination of
sagittal root positioning in maxillary anterior teeth. The sagittal root positioning and
root angulation plays a vital role for case selection in immediate implant placement.
Objective
To evaluate, classify and compare sagittal root position between different maxillary
anterior teeth.
Method
A 2-year retrospective study was conducted on 100 patients (53 males and 47
females) who fulfilled the inclusion criteria using cone beam computed tomographic
images. The relationship of root of tooth to its alveolar housing were recorded as
Class I to IV. In addition, the root angulation relative to the alveolar process was also
measured.
Result
The sagittal root position (SRP) calculated on six maxillary anterior teeth on average
was found to be 87.83% for Class I, 6.67% for Class II, 0.67% for Class III and 5.17%
for Class IV respectively. The mean root angulation was found to be higher with
canines on both side whereas lateral incisors had lesser mean root angulation.
Root angulation of maximum teeth were between 10-20 degrees where immediate
implant placement is possible.
Conclusion
Within the limitations of this study, the sagittal root positioning and root angulation
in Nepalese population showed a favorable result for immediate implant placement.
Maximum teeth were found to be close to the alveolar process with the exception
of few teeth.
