Accuracy comparison of guided surgery for dental implants according to the tissue of support: a systematic review and meta‐analysis

Abstract

It can be concluded that the tissue of the guide support influences the accuracy of computer-aided implant surgery.

The Use of Cone‐Beam Computed Tomography in Management of Patients Requiring Dental Implants: An American Academy of Periodontology Best Evidence Review

“…The corresponding figures with bone support were 1.3, 1.56, and 1.7 mm and 1.28 and 1.84 mm, respectively, hence favoring tooth support. The corresponding mean deviations at the apical level were for tooth support 1.01, 1.3, and 1.62 mm and 0.6 and 1.81 mm, respectively, and for bone support 1.6, 1.86, and 1.99 mm and 1.57 and 2.26 mm, respectively, also favoring tooth support 88 …”

“…With tooth support, the angle deviations were reported as 3.39°, 3.5°, and 4.4° in the three prospective studies and 2.91° and 4.88°, in the two retrospective studies included in the meta‐analysis. The corresponding figures with bone support were 4.73°, 5°, and 5.1°; and 4.63° and 9.31°, respectively, hence favoring tooth support 88 …”

“…Raico Gallardo et al's systematic review 88 found that with tooth support, the mean deviations at the entry point were 0.81, 1.1, and 1.31 mm in the three prospective studies and 0.87 and 2.08 mm in the two retrospective studies. The corresponding figures with bone support were 1.3, 1.56, and 1.7 mm and 1.28 and 1.84 mm, respectively, hence favoring tooth support.…”

Accuracy of the match between cone beam computed tomography and model scan data in template‐guided implant planning: A prospective controlled clinical study

“…It has been shown that the use of a surgical guide reduces inaccuracies in the transfer of Clin Implant Dent Relat Res. [9][10][11][12] Other factors influencing accuracy were the type of edentulous space, 13 the nature of the remaining teeth, 14,15 the implant system used, 16 and the surgical approach (flap vs flapless 17 or delayed vs immediate placement 18 ). [1][2][3][4] The individual steps of the planning process must be as precise as possible for the sum of the errors to ultimately yield a clinically tolerable discrepancy between the actual and planned implant positions.…”

Influence of surgical guide support and implant site location on accuracy of static Computer‐Assisted Implant Surgery

“…The literature reports conflicting results regarding the relationship between the type of guide support and the accuracy of postoperative implant position, in relation to the preoperative virtual planning. A previous systematic review (Schneider, Marquardt, Zwahlen, & Jung, ) reported that surgical accuracy is not necessarily related to the type of guide support, while other publications (Pozzi, Polizzi, & Moy, ; Raico Gallardo et al, ; Tahmaseb, Wismeijer, Coucke, & Derksen, ; Van Assche et al, ) found that tooth‐supported guides delivered more accurate results than mucosa‐ or bone‐supported guides. Furthermore, some reported that within the category of tooth‐supported guides, scenarios with single‐tooth gaps showed the most accurate results (Pozzi et al, ).…”
