Title The Effect of CBCT-Guided Treatment Planning on Dental Implant Survival is Not Yet Known
Clinical Question In a patient needing a dental implant, does using CBCT in preoperative assessment increase the likelihood of implants surviving for at least 10 years, compared to not using CBCT?
Clinical Bottom Line Implant treatment planning with CBCT has not yet been shown to affect implant survival, but CBCT does affect implant treatment planning in some cases.

(level of evidence)
#1) 23442085Correa/201471 patients/ 103 implant sites.Internally controlled cross-sectional study
Key resultsImplant site diameter was generally narrower and length shorter with CBCT-based cross-sectional imaging than with either CBCT-based panoramic reconstructions or digital panoramic images, in those cases in which there was a difference between imaging methods. The differences between methods were found primarily in posterior sites, but not in anterior sites.
#2) 24944961Guerrero/2014105 partially edentulous patients.Internally controlled cross-sectional study
Key resultsIn posterior sites, CBCT-based cross-sectional imaging indicated shorter lengths for dental implants than did panoramic images. The study also demonstrated higher subjectively-perceived image quality, and surgical confidence levels, for CBCT than for panoramic images.

The Evidence
The ideal study design to answer this clinical question would be an RCT of CBCT vs more traditional imaging, with an outcome of 10 year survival. No such studies have been indexed in PubMed, and presumably no such studies have been done. To demonstrate, as these papers have, that CBCT influences treatment planning is an important beginning. Perhaps a cohort study could be done comparing implant survival in practices that do use, and do not use, CBCT for implant treatment planning. Given the increasing popularity of CBCT, such a study would probably have to be retrospective. It is still reasonable to presume that improved treatment planning would improve implant longevity.
Applicability Correa reported on male and female patients ranging from 24 to 71 years (mean 44), not otherwise described, in Brazil. Guerrero reported dental school patients from Peru and Belgium, excluding only fully edentulous patients and patients "without pathology", age range not specified.
