摘要:
Sammenfatning (Danish summary)I det foreliggende arbejde meddeles en række makroskopiske, morfologiske iagttagelser, som forfatteren har gjort af roddannelsen på humane underkæbepraemolarer.Materialet bestod af 1712 præparater. Disse tænder var ekstraheret og indsamlet i Danmark. Indsamlingsperioden omfattede årene 1962‐67. For at blive indlemmet, i studiematerialet skulle præparaterne opfylde føgende krav: 1) roddannelsen måtte ikke være afsluttet på ekstraktionstidspunktet, eller 2) såfremt rodkomplekset på et præparat varfærdigdannet, skulle “lukningen” af apex have fundet sted umiddelbart inden ekstraktionen. Rodkomplekset skulle i øvrigt være helt eller meget nær ved “intakt”. Iagttagelserne blev foretaget direkte og meddet blotte øje.Ved undersøgelse af et ekstraktionsmateriale med henblik på rodontogenesen benytter man sig af, at dynamiske fænomener, der har betydning for roddannelsen, kan afspejle sig i de hårde tandvaev, som rodkomplekset er opbygget af. Disse processer kan derfor studeres indirekte—på grundlag af den “statiske” rodmorfologi. En forudsætning herfor er dog, at materialet udgøres af “unge” tænder, hvis rodkompleks ikke er sekundært forandret.For at vurdere den makro‐morfologiske variation i de pågældende tandtypers roddannelse blev føgende faktorer registreret:1. Antallet af separationsstrukturer (rodfurer, interradikulære tunger);2. Separationsstrukturernes position;3. Det initiale og det definitive separationstidspunkt;4. Separationshastigheden;5. Vakstmønster: kontinuært eller diskontinuært.En del af de gjorte fund

摘要:
SummaryA threedimensional measuring and recording system for mandibular movements is described, which graphically with time marking records the space‐coordinates of a measuring point, intra‐extraorrally fixed to the mandible.The apparatus, called “Electrognathograph” (E.G.) uses as electronic measuring devices resolvers, which are mounted on a movable X‐ray support. They are connected to a measuring point at the maxilla and at the mandible by 0,2 mm inoxydable steel wires. By measuring the movements of the maxilla (i.e. the movements of the head) and of the mandible and by continous electrical subtraction of the corresponding values the movements of the head are compensated for.The measuring results are continously recorded as a diagram, called “Electrognathogram” (E.G.G.), by a Visicorder‐Honeywell. In the E.G.G. the coordinates of the movements can be read off at every moment of the chewing act without any other preparatory work.By means of a “chewing”‐simulator, continously repeating the same “chewing‐cycle” and of an apparatus, producing accurate, kinetic distances, the E.G. has been tested and calibrated. Errors of the method are discussed and their effect on the results is calculated.By means of the E.G.G. of a normal patient the shape and the analysis of a c
