Aim:
To systematically evaluate the literature evidence regarding the suitability of the T-scan occlusal system for implant supported prostheses.
Materials And Methods:
A thorough bibliographic search was conducted on PubMed, Google Scholar, Cochrane library, Web of Science, EMBASE, and Scopus to collect relevant articles published from January 1, 2008 to August 30, 2021, using a combination of the following words: "T-scan," "Implant supported prostheses," and "dental implant" according to the PRISMA guidelines for the focused research question constructed using the PICO criteria. Randomized control trials, prospective studies, retrospective studies on the use of T-scan system in implant-supported prostheses reported in English language were included in the study.
Results:
This review consisted of 17 studies and 359 patients rehabilitated with 1,126 implants. In 3 studies, removable types of prostheses were given over implants, and in 14 studies, fixed types of prostheses were given. Nine studies determined the percentage of occlusal force magnitude and occlusion time sequence. Three studies measured the localization of the occlusion center. T-scan was used in two studies to measure the amount of gingival crevicular fluid after occlusal adjustment. The follow-up period ranged from 6 months to 2 years or more.
Conclusion:
T-scan proved with better results than other occlusal analysis indicators in terms of occlusion measurement, clinical execution, quantify the location and contact timing, and occlusion in 3D with more precision.
Clinical Significance:
T-scan occlusal analysis system is widely used in dentistry and there is an increase in the number of studies, so a systematic review evaluating and comparing results is warranted.
