Mandibular Bone Height Measurements for Tooth Implantation by Using Film and Digital Panoramic Radiograph

Abstract

An important objective of the preoperative radiographs evaluation of the implant is to determine the height and width of the bone available for implant insertion. The aim of the study is to confirm the ability of film and digital panoramic radiographs by measuring the distance from the crest of alveolar bone to the roof of the mandibular canal, also compare each type of radiographs using with the tracing chart reading which is a standard measure for both implant length and diameter that supply with the implant system.In this study thirty nine patients needing implants in the lower premolars and molars region in both sides were included. Digital panoramic radiograph were examined by using computerized analysis by software of dimax system , by measuring the distance from the crest of alveolar bone to the roof of the mandibular canal , while in film panoramic radiograph, a ruler was used to measure the distance from the crest of the alveolar bone to the roof of the mandibular canal with the utilization of a viewing box. it was found that film panoramic radiograph had higher value than digital panoramic radiograph in all sites of the teeth specially in the molar region.
