CAD-CAM vs Analog Occlusal Splints: Kev Tshawb Fawb Sib Piv ntawm Occlusal Kho

Nyob rau hauv ib tug pilot txoj kev tshawb no luam tawm nyob rau hauv lub Phau ntawv Journal of Esthetic and Restorative Dentistry, cov kws kho hniav tau delved rau hauv lub ntiaj teb no ntawm computer-aided tsim thiab computer-aided manufacturing (CAD-CAM) occlusal li, tshuaj xyuas lawv cov kev ua tau zoo nyob rau hauv kev sib piv rau analog txoj kev thaum nws los txog rau occlusal kho. 

Ua los ntawm pab pawg kws kho hniav nrog rau Alvaro Blasi DDS, CDT, Víctor Henarejos-Domingo DDS, MSc, Ricardo Palacios-Bañuelos DDS, MSc, Carla Vidal-Ponsoda DDS, MSc, Conrado Aparicio MSc, PhD, thiab Miguel Roig MD, , PhD, qhov kev tshawb fawb no tsom mus rau qhov pom ntawm qhov muaj txiaj ntsig zoo ntawm kev ua haujlwm digital tag nrho hauv kev xyaum kho hniav.

Cov txheej txheem thiab cov neeg koom tes

Txoj kev tshawb fawb no tau koom nrog yim tus neeg koom nrog uas tau txais ob yam khoom siv occlusal. Ib pawg ntawm cov khoom siv tau tsim los siv cov kev ua haujlwm zoo sib xws, thaum lwm cov txheej txheem ua raws li cov txheej txheem digital.

Txhawm rau ntsuas qhov kev hloov pauv hauv cov khoom siv occlusal no, txhua tus tau txheeb xyuas ua ntej thiab tom qab kev hloov kho occlusal, thiab cov ntaub ntawv raug tshuaj xyuas los ntawm kev siv rov qab engineering software. Tsis tas li ntawd, peb tus kws ntsuam xyuas kev ywj pheej tau ua haujlwm ib nrab ntawm qhov sib piv thiab qhov zoo, siv cov ntsuas qhov muag pom thiab cov kev ntsuas dichotomous. 

Kev txheeb xyuas qhov tseeb ntawm cov txiaj ntsig tau lees paub los ntawm Shapiro-Wilk qhov kev sim rau qhov kev xav ntawm kev faib khoom ib txwm muaj thiab cov kev ntsuam xyuas t-Student rau kev sib tw ua ke, nrog rau theem tseem ceeb ntawm p <0.05.

Cov Tseem Ceeb Nrhiav

3-Dimensional (3D) tsom xam ntawm occlusal li yielded lub hauv paus txhais tau tias square nqi. Qhov tseem ceeb, qhov nruab nrab lub hauv paus ntsiab lus square qhov tseem ceeb tau pom tias muaj ntau dua rau cov txheej txheem analog (0.23 ± 0.10 mm) piv rau cov txheej txheem digital (0.14 ± 0.07 mm). Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias qhov sib txawv no tsis ncav cuag qhov tseem ceeb (paired t-Student test; p = 0.106) ntawm ob txoj kev tsim khoom.

Thaum ntsuas qhov pom qhov ntsuas qhov ntsuas qhov ntsuas, qhov sib txawv tseem ceeb tshwm sim ntawm cov digital (5.08 ± 2.4 cm) thiab analog (3.80 ± 3.3 cm) cov tswv yim (p <0.001). Tsis tas li ntawd, cov kev hloov pauv hauv cov kev ntsuas ntawm peb tus neeg soj ntsuam tau pom, nrog tus ntsuas 3 qhia qhov sib txawv tseem ceeb piv rau lwm tus neeg ntsuas (p <0.05). 

Txawm li cas los xij, tag nrho peb tus neeg soj ntsuam tau ua tiav qhov kev pom zoo hauv qhov kev ntsuam xyuas zoo dichotomous hauv 62% ntawm cov neeg mob, nrog tsawg kawg ob tus neeg ntsuam xyuas pom zoo hauv 100% ntawm kev ntsuam xyuas.

Qhov tshwm sim thiab kev txiav txim

Qhov kev tshawb nrhiav qhov kev sim no muaj qhov cuam tshuam tseem ceeb rau kev kho hniav. Kev tshawb fawb qhia tias cov khoom siv occlusal tsim los ntawm kev ua haujlwm digital tag nrho yuav xav tau kev hloov kho occlusal tsawg dua piv rau cov uas tsim los ntawm kev ua haujlwm analog. Txawm hais tias qhov sib txawv ntawm cov hauv paus ntsiab lus square qhov tseem ceeb tsis ncav cuag qhov tseem ceeb, qhov tseem ceeb ntawm kev kho qhov kev txo qis hauv kev hloov kho tsis tuaj yeem raug saib xyuas.

Cov txiaj ntsig zoo ntawm cov kev ua haujlwm digital hauv kev tsim cov cuab yeej occlusal suav nrog txo lub sijhawm lub rooj zaum, uas tuaj yeem txhim kho tag nrho cov kev paub rau cov neeg mob thiab cov kws kho mob. Cov kev tshawb pom no qhia tau hais tias kev sib koom ua haujlwm digital hauv kev tsim cov khoom siv occlusal tuaj yeem yog txoj hauv kev zoo rau cov kws kho hniav.

Nws yog ib qho tseem ceeb kom lees paub tias txoj kev tshawb no muaj kev txwv, suav nrog nws cov qauv me me thiab tsuas yog tsom rau kev hloov kho occlusal ntawm qhov kev mus ntsib. Kev tshawb fawb yav tom ntej tuaj yeem tshawb nrhiav qhov dav dav ntawm kev kho mob hnav thiab kev hloov kho cov khoom siv occlusal ntawm kev rov qab los tom ntej.
