All relevant studies were screened for eligibility; only English\u2010language, peer\u2010reviewed articles containing extractable data on thin or ultrathin ceramic crowns (measuring 0.6 to 0.9\u00a0mm and \u2264 0.5\u00a0mm, respectively) were included in this review. The meta\u2010analysis was performed using RevMan 5.4 software from the Cochrane Collaboration, with\n                      <jats:italic>p<\/jats:italic>\n                      \u2264 0.05.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 14 studies were included. Both thin and ultrathin crowns demonstrated durability under thermomechanical loading for 5 years during clinical simulation. The fatigue survival rates under stepwise loading presented conflicting findings, which may be attributed to variations in procedural methodologies or cementation protocols. The mechanical strength of thin and ultrathin crowns was sufficient to endure occlusal stresses exceeding 1100 N. However, the fracture resistance of thin and ultrathin crowns was found to be statistically significantly lower than that of thick ceramic crowns (\n                      <jats:italic>p<\/jats:italic>\n                      = 0.01 and\n                      <jats:italic>p<\/jats:italic>\n                      \u2264 0.001, respectively). Furthermore, all crowns cemented with conventional cement exhibited statistically significant weakness compared to those bonded with resin cement (\n                      <jats:italic>p<\/jats:italic>\n                      \u2264 0.001). Lithium disilicate and nano lithium disilicate crowns revealed more stable optical properties than zirconia\u2010reinforced lithium silicate, and all exhibited more staining with longer exposure time to colored drinks. Resin ceramic crowns revealed the highest microleakage rate compared with zirconia and composite crowns.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Laboratory evidence suggests that thin and ultrathin ceramic crowns exhibit favorable survival rates and fracture resistance. Crowns fabricated from high\u2010strength ceramics such as 3Y\u2010TZP performed better with conventional cements, whereas crowns cemented with adhesive resin protocols yielded similar fracture resistance regardless of crown thickness or material. Optical properties and microleakage are crown\u2010material and time\u2010dependent; however, evidence is scarce and remains insufficient. Thin and ultrathin ceramic crowns offer a conservative treatment option. Adhesive cementation enhances their survival, while the choice of ceramic material, cementation protocol, and luting shade is critical for optimal esthetics.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/jopr.70044","type":"journal-article","created":{"date-parts":[[2025,10,14]],"date-time":"2025-10-14T04:51:47Z","timestamp":1760417507000},"page":"995-1007","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Mechanical behavior and laboratory survival of thin and ultrathin ceramic crowns: A systematic review and meta\u2010analysis"],"prefix":"10.1111","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2112-5326","authenticated-orcid":false,"given":"Mohammed Ahmed","family":"Alghauli","sequence":"first","affiliation":[{"name":"Department of Prosthodontics Faculty of Dentistry Ibb University  Ibb Yemen"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6536-8269","authenticated-orcid":false,"given":"Ahmed Yaseen","family":"Alqutaibi","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics Faculty of Dentistry Ibb University  Ibb Yemen"},{"name":"Substitutive Dental Sciences Department College of Dentistry Taibah University  Madinah Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,10,13]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/jerd.12706"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prosdent.2020.10.009"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1067\/mpr.2002.124094"},{"key":"e_1_2_7_5_1","first-page":"241","article-title":"Tooth structure removal associated with various preparation designs for posterior teeth","volume":"22","author":"Edelhoff D","year":"2002","journal-title":"Int J Periodontics Restorative Dent"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.2186\/jpr.JPOR_2019_643"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.2334\/josnusd.17-0176"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/jopr.13108"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2842.2005.01588.x"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.2186\/jpr.JPR_D_20_00082"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prosdent.2022.04.006"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/jerd.13228"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.dental.2023.05.006"},{"key":"e_1_2_7_14_1","first-page":"309","article-title":"The effect of dentin bonding and material thickness on the flexural properties of a lithium\u2010disilicate glass\u2010ceramic","volume":"23","author":"De Angelis F","year":"2021","journal-title":"J Adhes Dent"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.n71"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prosdent.2024.12.002"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jebdp.2012.10.001"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.2147\/CCIDE.S286826"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1080\/23335432.2024.2303121"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/jerd.13127"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.3390\/ma17020365"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.dental.2011.11.019"},{"key":"e_1_2_7_23_1","doi-asserted-by":"publisher","DOI":"10.3390\/ma15114011"},{"key":"e_1_2_7_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prosdent.2015.04.014"},{"key":"e_1_2_7_25_1","doi-asserted-by":"publisher","DOI":"10.4047\/jap.2021.13.5.269"},{"key":"e_1_2_7_26_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prosdent.2019.11.026"},{"key":"e_1_2_7_27_1","first-page":"1311","article-title":"Fracture strength of thin monolithic zirconia crowns with varying thickness and configuration of finish lines\u2010an in vitro study","volume":"25","author":"Singh K","year":"2022","journal-title":"Cardiometry"},{"key":"e_1_2_7_28_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmbbm.2016.04.014"},{"key":"e_1_2_7_29_1","doi-asserted-by":"publisher","DOI":"10.4047\/jap.2018.10.2.79"},{"key":"e_1_2_7_30_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00784-023-05001-6"},{"key":"e_1_2_7_31_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00784-023-05262-1"},{"key":"e_1_2_7_32_1","doi-asserted-by":"publisher","DOI":"10.11607\/prd.4270"},{"key":"e_1_2_7_33_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpor.2018.05.004"},{"key":"e_1_2_7_34_1","first-page":"7","article-title":"Are adhesive technologies needed to support ceramics?
