EVALUATION OF EFFECT OF ANATOMIC LOCATION ON ARTEFACT FORMATION DUE TO DENTAL IMPLANT IN CBCT- A RETROSPECTIVE STUDY

Abstract

Purpose:   Artefact quantification can aid in identifying the impact of implant artefact on anatomic site and diagnostic accuracy. Therefore, this study was undertaken to evaluate the effect of anatomical location on artefacts formation caused by titanium dental implants using CBCT.

Materials and method: Total 104 CBCT scans with titanium dental implants placed in anterior and posterior region of jaw were obtained and were equally divided into 4 groups according to the location of implant. The image was then analyzed by Image J Software and histogram was obtained. The minimum and maximum grey values along with their actual standard deviation were determined using the histogram to determine artefact quantification.

Results: Both maxilla and mandible showed a significant higher percentage of artefacts at all the levels except level 1. No significant difference was observed in the percentage of metal artefacts produced by implants between maxilla and mandible irrespective of anterior and posterior region. No statistically significant difference was observed in the percentage of metal artefacts produced by implants between isolated and adjacent implants.

Conclusion: The anatomic location influences the amount of metal artefacts generated, as more predilection for the posterior region of maxilla and mandible was found while intergroup comparison showed significant higher percentage of quantification at the cervical level of implant.
