UNLABELLED: This study aims to evaluate the accuracy of immediate implants in mandibular molars between the conventional method and the pre-extractive inter-radicular method.
MATERIALS AND METHODS: A total of 20 patients were equally divided into two groups. Implants were placed using the conventional method (Group A) and pre-extractive inte-rradicular method (Group B). Coronal, apical and angular deviation between planned and placed implants were evaluated by superimposing preoperative and postoperative three-dimensional (3D) STL models in Geomagic Freeform software. The data were subjected to an unpaired Student t-test.
RESULTS: Results revealed that the coronal, apical and angular deviation were lower in the pre-extractive inter-radicular drilling method than in the conventional method, which was statistically significant. Apical deviation was greater than coronal deviation in both the sagittal and coronal planes. It was also found that the mean deviation was greater in the sagittal plane (mesio-distal axis) than in the coronal plane (bucco-lingual axis).
CONCLUSION: Comparison of the two methods revealed significant changes between the planned and actual positions of implant. When stringent steps were followed, the degree of deviation was found to be less in the pre-extractive inter-radicular approach, proving it to be more accurate than the conventional method. However, large-scale research studies are required to extrapolate our findings.
