Milled in Versus Round Bar for Mini-implant Retained Mandibular Overdentures

Long cone paralleling technique and a film holder designed specifically for implant imaging were used for intraoral radiograph. To maintain the same film- implant distance and cone implant distance, a modification were carried out for the film holder. This modification is a hole drilled exactly above the implant fixture so the distance were maintained during subsequent film exposures. Through this modification, standardized radiographs were achieved.
