Abstract

Recently, Dental implants have taken the dental rehabilitation to another level. Dental implants are highly preferred over other rehabilitation techniques, as they have a more conservative approach with minimal damage to other adjacent structures. The aim of the study was to evaluate the prevalence of anatomical variations in maxilla and mandible on CBCT images of patients referred for dental implants. In our study, a total of 102 CBCT images comprising of 60 males & and 42 females with mean age of 50 years & 45 years were analysed. We found that in approximately 50% of the cases, the anterior loop of mental nerve was seen and lingual foramen was identified in the anterior part of the mandible in about 20% cases. Two-dimensional radiographs have been used for a long time as the only diagnostic tool in implant dentistry. However, radiographs may seem to be adequate for patients with wide residual ridges but CBCT effectively brings together prosthetic and surgical considerations which are important for beauty, restoration and prosthetic indices.

Highlights

Dental implants have taken the dental treatments ablaze especially amongst the urban areas
In approximately 50% of the cases, the anterior loop of mental nerve was seen and the lingual foramen was identified in the anterior part of the mandible in about 20% cases
2% of the total scans analyzed were sent with radiographic stent for implant treatment planning

Summary

Introduction

Dental implants have taken the dental treatments ablaze especially amongst the urban areas. 1. Implant placement requires the assessment of many parameters, all of which directly or indirectly affects the treatment outcome and its prognosis. Restorative requirements, adequate surgical training, experience in selecting implant system and visualization of the desired end result of the treatment. 1. Surgery and Prosthodontic replacement forms the 2 important segments of dental implants. The expertise of a maxillofacial radiologist would be necessary for proper interpretation of anatomical structures and or / pathosis in or outside the primary area of interest, which remains the hidden/unrecognized segment of the triangle whose impact is felt at each and every stage of the implant placement
