Developing evidence-based clinical imaging guidelines of justification for radiographic examination after dental implant installation

Table 8 Recommendation matrix of the existing guideline

	Guideline A	Guideline B	Guideline C
Recommendation	Taking into account the justication principle, it was recommended that CBCT should be reserved as a supplementary imaging technique where conventional- radiography failed to answer the question for which imaging was required.	In most cases, conventional radiographs provide the necessary information, but additional images may be needed if there are complications after surgery (e.g., nerve damage or postoperative infections in relation to sinus cavities close to implants).	CBCT is not part of a “routine protocol” for postoperative examinations “unless there is a need for assessments in situations where some kind of complications have occurred, such as nerve damage, postoperative infections in relation to nasal and/or sinus cavities close to implants” (Harris et al. 2002).
