Abstract

Abstract: Aim: To systematically assess the current dental literature comparing the accuracy of computer‐aided implant surgery when using different supporting tissues (tooth, mucosa, or bone). Material and Methods: Two reviewers searched PubMed (1972 to January 2015) and the Cochrane Central Register of Controlled Trials (Central) (2002 to January 2015). For the assessment of accuracy, studies were included with the following outcome measures: (i) angle deviation, (ii) deviation at the entry point, and (iii) deviation at the apex. Results: Eight clinical studies from the 1602 articles initially identified met the inclusion criteria for the qualitative analysis. Four studies ( n = 599 implants) were evaluated using meta‐analysis. The bone‐supported guides showed a statistically significant greater deviation in angle ( P < 0.001), entry point ( P = 0.01), and the apex ( P = 0.001) when compared to the tooth‐supported guides. Conversely, when only retrospective studies were analyzed, not significant differences are revealed in the deviation of the entry point and apex. The mucosa‐supported guides indicated a statistically significant greater reduction in angle deviation ( P = 0.02), deviation at the entry point ( P = 0.002), and deviation at the apex ( P = 0.04) when compared to the bone‐supported guides. Between the mucosa‐ and tooth‐supported guides, there were no statistically significant differences for any of the outcome measures. Conclusions: It can be concluded that the tissue of the guide support influences the accuracy of computer‐aided implant surgery.
