Presurgical evaluation of bony implant sites using panoramic radiography and cone beam computed tomography—influence of medical education

subject

description

The aim of this study was to compare the subjective quality rating of panoramic radiography (PAN) and CBCT in the planning of dental implant procedures by clinicians with different educational backgrounds.Radiographic images (PAN and CBCT) of 42 patients were examined as follows: the maxillary (MX) anterior region of patients, the MX posterior region of 16 patients and the mandibular (MD) posterior region of 16 patients. These sites were used for planning of dental implant insertion. Data sets were analyzed by examiners with different training backgrounds: three general practitioners (GP), three oral surgeons (OS) and three maxillofacial surgeons (MS). A standardized questionnaire in a standardized setting was answered by participants.The majority of participants rated an additional CBCT as "required" (14.0%) or "reasonable" (56.1%). These ratings depended strongly on the area of interest (MX anterior region: 31.1 and 58.9%; MX posterior region: 14.6 and 62.5%; and MD posterior region: 2.8% and 47.9%). MS classified CBCT as required more often than GP and OS (23.8 vs 10.3 and 7.9%; p  0.001). With the additional information of CBCT, "therapy affecting" ratings were stated high in all groups.Especially in the anterior and posterior MX, significant subjective benefits for an additional CBCT were seen for planning of dental implant procedures. Participants with fundamental medical education asked for CBCT more often. The results indicate that an improved education in three-dimensional dental radiology is necessary.
