Abstract
The aim of this systematic review and meta-analysis is to analyze the accuracy of implant placement using computer-assisted dynamic navigation procedures. An electronic literature search was carried out, supplemented by a manual search. The literature search was completed in June 2020. The results of in vitro and clinical studies were recorded separately from each other. For inclusion in the review, the studies had to examine at least the prosthetically relevant parameters for angle deviation, as well as global deviation or lateral deviation at the platform of the implant. Sixteen of 320 articles were included in the investigation: nine in vitro and seven clinical studies. The meta-analysis showed values of 4.1° for the clinical studies (95% CI, 3.12–5.10) and 3.7° for the in vitro studies (95% CI, 2.31–5.10) in terms of the angle deviation. The global deviation at the implant apex of the implant was 1.00 mm for the clinical studies (95% CI, 0.83–1.16) and 0.91 mm for the in vitro studies (95% CI, 0.60–1.12). These values indicate no significant difference between the clinical and in vitro studies. The results of this systematic review show a clinical accuracy of dynamic computer-assisted navigation that is comparable to that of static navigation. However, the dynamic navigation systems show a great heterogeneity that must be taken into account. Moreover, currently there are few clinical data available. Therefore, further investigations into the practicability of dynamic navigation seem necessary.
Highlights
The objective of an implant prosthetic restoration is the functional and esthetic rehabilitation of the masticatory organ after tooth loss [1]
This systematic review was designed in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines [26]
The question posed was: “How much accuracy can be achieved clinically and on the model with dynamic computer-assisted implant placement?” The protocol of this systematic review was registered in the international database of prospectively registered systematic reviews in health and social care PROSPERO (CRD-No 42020179128)
Summary
The objective of an implant prosthetic restoration is the functional and esthetic rehabilitation of the masticatory organ after tooth loss [1]. Driven planning has been shown to be suitable for achieving this goal in an optimal and predictable way [2]. Various aspects must be considered and assessed . The bone condition [3], the soft tissue condition [4], the inter-implant distance [5], or the position of the [6] cement space must be taken into account in the planning. The long-term success of an implant restoration is determined by multiple factors [7]. An established process is digital three-dimensional (3D) planning. The actual condition of the alveolar bone is recorded using 3D imaging (computed tomography (CT))
