20.500.12556/RUL-167636 Značilnosti obraza starejših oseb in spremembe po snemnoprotetični rehabilitaciji brezzobih ​​​Facial characteristics of older adults and changes after prosthodontic rehabilitation of edentulous older adults Uvod Namen študije je bil opredeliti značilnosti obraza starejših in jih primerjati z mlajšimi odraslimi ločeno po spolu ter ovrednotiti vpliv ohranjenih zob in totalnih snemnih protez. Metode V raziskavo smo vključili 100 mlajših (20–30 let) in 162 starejših odraslih (> 65 let). 90 starejših odraslih smo razdelili v 3 podskupine: brezzobi, delno brezzobi, z ohranjenim zobovjem. 102 brezzobima starejšima odraslima smo izdelali totalni snemni protezi. Obrazne posnetke smo naredili s 3D-optično kamero Artec MHT in jih kefalometrično analizirali (RapidForm®) ter izračunali obrazne parametre. Področno analizo smo naredili s superpozicijo obraza brez in z vstavljenima protezama. Statistične razlike in oceno vpliva smo ugotavljali s parnim in neparni t-testom, analizo variance in multivariantno linearno regresijo (p < 0.05). Rezultati Ženski obrazi so bolj okrogli, manjši in bolj simetrični od moških. Moški imajo širša usta, daljše zgornje ustnice in večje nosove, kar je bolj izraženo pri starejših. Starejši odrasli imajo v primerjavi z mlajšimi širši, daljši in bolj asimetričen obraz, daljšo zgornjo ustnico, večji nos, manjši nazolabialni kot, ožjo zgornjo in spodnjo ustnično rdečino, bolj raven obrazni profil. Povišan ITM je povezan s širšimi obrazi in nosovi ter bolj konkavnimi obraznimi profili, večja telesna višina pa s povečano obrazno višino in širšimi usti. Starostne obrazne spremembe so najbolj izražene pri brezzobih, ki imajo v primerjavi z vrstniki z ohranjenim zobovjem krajšo obrazno višino, večji nazolabialni kot, ožja usta, krajšo zgornjo ustnico, ožji ustnični rdečini ter bolj raven obrazni profil. Po snemnoprotetični oskrbi nastanejo spremembe v perioralnem predelu: širša usta, daljša zgornja ustnica, širša zgornja ustnična rdečina in bolj izbočen profil. Področna primerjava pokaže polnejša lica, na kar proteza nima neposrednega vpliva. Obrazi z vstavljenimi protezami so krajši in bolj vbočeni od tistih z ohranjenim zobovjem. Zaključek Razmerja obraza so spremenjena pri starejših odraslih, najbolj pri brezzobih. Poleg pozitivnega učinka oskrbe s snemnimi protezami v perioralnem predelu smo opazili tudi polnejša lica, manjše obrazne višine in bolj raven obrazni profil. Introduction The aim of the study was to evaluate facial characteristics of older adults and compare them with younger ones, separated by gender, and assess the impact of preserved teeth and complete dentures. Methods The study included 100 younger adults (aged 20–30) and 162 older adults (aged >65). 90 older adults were divided into 3 subgroups: edentulous, partially edentulous, toothed. 102 edentulous older adults were rehabilitated with complete dentures. Facial scans were captured using a 3D optical camera (Artec MHT) and were cephalometrically analysed (RapidForm®) to calculate facial parameters. Regional analysis was performed by superimposing the face without and with inserted dentures. Paired and unpaired t-tests, analysis of variance and multivariate linear regression were used to calculate statistical differences (p < 0.05). Results Female faces are rounder, smaller, and more symmetrical than male faces. Males have wider mouths, longer upper lips, and larger noses, which is more pronounced in older adults. Older adults have, in comparison with younger ones, wider, longer and more asymmetrical faces, longer upper lips, larger noses, smaller nasolabial angles, narrower upper and lower vermilions and flatter facial profiles. A higher BMI is associated with wider faces and noses, as well as more concave facial profiles. Greater body height is linked to increased facial height and wider mouths. Age-related facial changes are most pronounced in edentulous individuals, who, compared to toothed peers, have shorter facial heights, larger nasolabial angles, narrower mouths, shorter upper lips, narrower vermilions and flatter facial profiles. After rehabilitation with dentures, changes are visible in the perioral region: wider mouths, longer upper lips, wider upper vermilions and more prominent profiles. The regional comparison shows fuller cheeks: denture does not have a direct influence on them. Faces with inserted dentures are shorter and more convex compared to those with preserved teeth. Conclusion Facial proportions are modified in older adults, most expressed in the edentulous. Beside the positive effect of rehabilitation with complete dentures in the perioral region, we also observed fuller cheeks, reduced facial height, and a flatter facial profile. starejši odrasli obrazne značilnosti kefalometrična analiza obrazne meritve gerodontologija brezzobi pacient brezzobost zobovje protetična rehabilitacija snemna proteza older adults facial characteristics cephalometric analysis facial measurements gerodontology edentulous patients edentulism dentition prosthodontic rehabilitation complete dentures true false false Slovenski jezik Angleški jezik Doktorsko delo/naloga 2025-03-05 07:16:02 2025-03-05 07:16:11 2025-03-06 04:01:03 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 30497 6760.pdf 6760.pdf 1 025D0F630709D2127F25CADB09EE7E65 e458388e4664be3b3830aa5d675f85c65bfe21054bc1f215b1e88197b92df212 66af1c35-f988-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200325 Medicinska fakulteta 0 0 0
