Custo-benefício do escaneamento intraoral em casos de próteses sobre implantes em comparação com a moldagem convencional: uma revisão sistemática.

Abstract

The general object of this present study is to set forth a systematic review of the available literature regarding the most cost-effective ratio between intraoral scanning and conventional moulding regarding prostheses on implants. This systematic review was registered in PROSPERO (CRD42023416984) to avoid duplicates. Randomized clinical trials and prospective clinical studies resulting from an online search in selected databases (PubMed; Cochrane Library; SciELO; LILACS and Gray Literature) were included, the publications of which being restricted to the years 2013-2023 and to the English language. Furthermore, an additional search was performed in specific journals, such as: Journal of Dentistry, Journal of Oral Rehabilitation, Journal of Prosthetic Dentistry. A research question was defined based on the population, intervention, comparison, and objectives (PICO), which is: “Is digital scanning more cost-effective than conventional moulding taking in cases of prosthesis on implants?” Nine articles were eligible for the study, specific data were tabulated and examined. Cochrane RoB 2.0 and ROBINS 1’s tools were used for the analysis of the risk of bias. The GRADE system was also used with the objective of evaluating the scientific evidence included in this review. A meta-analysis evaluated clinical time, patient perception, and crown adjustment time, showing significant preponderance of scanning over conventional impression regarding the patient perception and the crown adjustment time. It was possible to assume that intraoral scanning introduces better rates regarding the patients' perception, in addition to consuming less clinical time during its operation. Regarding accuracy, both procedures can reproduce the oral cavity and its structures in a suitable approach. It was not possible to conclude which technique characterizes the best cost-effectiveness.
