加快正畸牙齿移动的方法.ppt

加快正畸牙齿移动的方法,研究的三个方向：,药物刺激机械生理性刺激手术加速,药物刺激,激素类药物：前列腺素（PG）、甲状旁腺素（PTH）、肾上腺皮质激素等钙调节剂：骨钙素（OC）等中药类：丹参、灯盏花等,机械生理性刺激,激光磁场超声波：选择了13例对称拔牙正畸病例，实验侧局部给予超声波，10mind14d。结果实验侧尖牙移动速度比对照侧提高28.67%。振动,手术加速,骨皮质切开术corticotomy牙周辅助加速成骨治疗periodontallyacceleratedosteogenicorthodontics,PAOO牵张成骨DentoalveolarDistraction(DAD)手术优先矫治surgeryfirstorthognathicapproach,正畸力作用于牙齿，引起牙槽骨的改建，压力侧出现骨吸收，张力侧出现骨沉积，从而产生牙齿移动。理论上，凡能促进骨组织改建的外源性因素均可加速正畸牙齿移动。,Anoveldeviceinorthodontics,-AcceleDent,WhatisAcceleDentAura?,Asimple-to-use,hands-freedevicedesignedforfasterorthodontictreatmentwithonly20minutesdailyuse.,ItsFast,Clinicallyproventomoveteethupto50%fasterinaUSclinicaltrial.,AcceleDentisdesignedtoworkwithallexistingorthodonticappliancesincludingfixedappliancesandclearaligners.,ItsSafe,ClearedbytheUnitedStatesFoodandDrugAdministration(FDA)andavailableonlybyprescriptionfromyourorthodontist,ItsGentle,AcceleDentpatientshavereportedreduceddiscomfortwiththeirorthodontics.,AcceleDentAuraComponents:,ActivatorTheheartofAcceleDentAurathesmall,lightweightActivatorgeneratesgentlemicropulsestosafelyaccelerateboneremodeling.ItincludesaUSBinterface,whchcanbepluggeddirectlyintoacomputertoviewpatientusagehistoryviatheFastTracReport.,AcceleDentAuraComponents:,MouthpieceTheMouthpieceprovidesacomfortablefitsnapseasilyonandofftheActivatorfortransportandcleaning.,AcceleDentAuraComponents:,USBextensioncablewithpoweradapterAllowsforeasy,convenientcharging,AcceleDentAuraComponents:,TravelCaseTheTravelCasekeepsthecomponentssafe,cleanandsecure.,HowAcceleDentAuraWorks?,SoftPulseTechnologyPartofthewaythatorthodonticsworksisbychangingorremodelingthebonessurroundingyourteeth.Asthisremodelingprocessisaccelerated,yourteethmovemorequickly.SoftPulseTechnologyisdesignedtospeedupboneremodeling,acceleratingtoothmovement,Thedeviceusestheapplicationofcyclicforcestomoveteethinbonefasterthroughacceleratedboneremodeling.,Theappliedforce(0.2Newtonsor20grams)isintendedtobebarelynoticeableandshouldnotbeuncomfortable.someresearchershavetheorisedthatthepulsingmayactuallydecreasepainassociatedwithstandardortho-donticadjustments,SCIENTIFICEVIDENCE,SutureGrowthModulatedbytheOscillatoryComponentofMicromechanicalStrain,SCIENTIFICEVIDENCE,SCIENTIFICEVIDENCE,SCIENTIFICEVIDENCE,SCIENTIFICEVIDENCE,SCIENTIFICEVIDENCE,SCIENTIFICEVIDENCE,SCIENTIFICEVIDENCE,SCIENTIFICEVIDENCE,CLINICALEVIDENCE,AcceleDentIncreasestheRateofOrthodonticToothMovement:ResultsofaRandomizedControlledClinicalTrial,CLINICALEVIDENCE,CLINICALEVIDENCE,CLINICALEVIDENCE,CLINICALEVIDENCE,Theperimeterwasdefinedbytracingthelabiolingualcentersofeachtoothfromcaninetocanine.,CLINICALEVIDENCE,CLINICALEVIDENCE,CLINICALEVIDENCE,CLINICALEVIDENCE,CLINICALEVIDENCE,CLINICALEVIDENCE,TheresultsoftherandomizedcontrolledclinicaltrialdemonstratethatAcceleDentcanincreasetherateoftoothmovementwhenusedinconjunctionwithconventionalorthodontics.UseofAcceleDentdidnotincreasetheriskofeitherrootresorption,CASEREPORT,18yearoldmaleClassIIIcombinationortho在这一分解代谢的过程中骨密度虽然降低，但牙槽骨骨量并没有减少;正畸力施加使得牙根周围骨基质及骨胶原软组织基质随之移动;在随后的再矿化过程中新骨沉积，类骨质基质再矿化，重新包绕牙根周围。,骨皮质切开术后一段时间可以加快正畸牙齿移动的速度，而该过程是基于引发现象后牙槽骨吸收和重建过程（RAP）.,临床应用,解除拥挤矫正上前牙唇倾，加速前牙内收，改善前突面型骨性三类错合畸形下前牙舌倾的去代偿个别牙齿的错合畸形也有很好的疗效，压低伸长磨，牵引埋伏牙，根骨黏粘牙齿解除后牙反牙合,LowerIncisorRetractionwithaModifiedCorticotomyAngleOrthodontist,Vol76,No5,2019,Inthecurrentcasereport,thetotalorthodontictreat-menttime(16months)wasdramaticallyreducedwh
