Therefore, it is of interest to evaluate and compare the fracture toughness of yttria-stabilized zirconia and lithium disilicate ceramics. Forty CAD\/CAM-fabricated specimens were tested using Vickers indentation and fracture toughness was calculated via the indentation fracture method. Zirconia showed significantly higher fracture toughness (408.61 \u00b1 44.21 MPa\u00b7m\u00b9\/\u00b2) and hardness than lithium disilicate (359.40 \u00b1 19.00 MPa\u00b7m\u00b9\/\u00b2) (p &lt; 0.0001). Zirconia demonstrates superior crack resistance compared to lithium disilicate, supporting its use in high-stress clinical applications.<\/jats:p>","DOI":"10.6026\/973206300214796","type":"journal-article","created":{"date-parts":[[2026,1,14]],"date-time":"2026-01-14T03:27:36Z","timestamp":1768361256000},"page":"4796-4802","source":"Crossref","is-referenced-by-count":0,"title":["Comparative evaluation of fracture toughness between zirconia and lithium disilicate ceramics: An in vitro study"],"prefix":"10.6026","volume":"21","author":[{"name":"Department of Prosthodontics, G Pulla Reddy Dental College And Hospital, G P R Nagar, Nandyal Road, Kurnool, Andhra Pradesh, India","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simhachalam Reddy","family":"N","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Divya","family":"Bekkem","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Duggineni","family":"Sreenivasulu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Addugala","family":"Hemavardhini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Addugala","family":"Hemavardhini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Prosthodontics, G Pulla Reddy Dental College And Hospital, G P R Nagar, Nandyal Road, Kurnool, Andhra Pradesh, India","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lakshmi Sowjanya","family":"J","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Prosthodontics, Kamineni Institute of Dental Sciences, Narketpally, Sreepuram, Nalgonda, Telangana, India","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chandra Obula Reddy","family":"B","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Prosthodontics, G Pulla Reddy Dental College And Hospital, G P R Nagar, Nandyal Road, Kurnool, Andhra Pradesh, India","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4070","published-online":{"date-parts":[[2025,12,15]]},"container-title":["Bioinformation"],"original-title":[],"deposited":{"date-parts":[[2026,1,14]],"date-time":"2026-01-14T03:28:42Z","timestamp":1768361322000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.bioinformation.net\/021\/973206300214796.htm"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,12,15]]},"references-count":0,"journal-issue":{"issue":"12","published-online":{"date-parts":[[2025,12,15]]},"published-print":{"date-parts":[[2025,12,15]]}},"URL":"https:\/\/doi.org\/10.6026\/973206300214796","relation":{},"ISSN":["0973-8894"],"issn-type":[{"value":"0973-8894","type":"print"}],"subject":[],"published":{"date-parts":[[2025,12,15]]}}}
