Determination of the accuracy of imaging methods to evaluate bone in maxilla for implant placement- An invitro study
Journal Title: Journal of Oral Medicine, Oral Surgery, Oral Pathology and Oral Radiology - Year 2018, Vol 4, Issue 1
Abstract
Introduction Dental implants are now treatment of choice in replacing of missing teeth Treatment outcomes with dental implants are predictable and favourable Long term implant survival is dependent on proper implant planning and case selection Precision in dental implant placement is the sine qua non for dental implant success Radiographic examinations are the only noninvasive technique for visualizing the bone topography volume and location of vital structures like mandibular canal and maxillary sinuses In this study we have tried to evaluate commonly used radiographic modalities in implant planning orthopantomograph OPG and computed tomography CT and tried to compare their accuracy with direct measurements with skull sectioning at predetermined maxillary first molar regionnbspnbspMaterials and Methods Ten dry human skulls were subjected to OPG CT and skull sectioning respectively Measurements on height and width of the alveolar bone were noted at the maxillary first molar region and results were comparedResults The mean height of alveolar bone measured using OPG CT and Skull sectioning was found to be 12mm 94mm and 93mm respectively The mean value of width of alveolar bone measured using CT and skull sectioning was found to be equal at 103mm Additionally the mean rate of magnification for OPG was found to be 40 whereas for CT it was just 2nbspKeywordsnbspOrthopantomography Computed tomography Dental Implants Maxillary sinus
