In the TCMCJ both articulating surfaces are saddle-shaped. The aim was to geometrically survey the shapes of the articulating surfaces using precise replicas of 28 TCMCJs. Methods: None of these 56 articulating surfaces did mathematically extend the differential geometrical neighbourhood around the main saddle point so that each surface could be characterised by three main parameters: the two extreme radii of curvature in the main saddle point and the angle between the saddles' asymptotics (straight lines). Results: The articulating surfaces, when contacting at the respective main saddle points, are incongruent. Hence, the TCMCJ has functionally five kinematical degrees of freedom (DOF); two DOF belong to flexion/extension, two to ab-/adduction. These four DOF are controlled by the muscular apparatus. The fifth DOF, axial rotation, cannot be adjusted but stabilized by the muscular apparatus so that physiologically under compressive load axial rotation does not exceed an angle of approximately +/- 3 degrees. Conclusions: The TCMCJ can be stimulated by the muscular apparatus to circumduct. The mechanisms are traced back to the curvature incongruity of the saddle surfaces. Hence we mathematically proved that none of the individual saddle surfaces can be described by a quadratic saddle surface as is often assumed in literature. We derived an algebraic formula with which the articulating surfaces in the TCMCJ can be quantitatively described. This formula can be used to shape the articulating surfaces in physiologically equivalent TCMCJ-prostheses."],["dc.identifier.doi","10.5277/ABB-00386-2015-02"],["dc.identifier.isi","000379915800011"],["dc.identifier.pmid","27405537"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/41834"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wroclaw Univ Technology"],["dc.relation.issn","1509-409X"],["dc.title","The thumb carpometacarpal joint: curvature morphology of the articulating surfaces, mathematical description and mechanical functioning"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]Details DOI PMID PMC WOS2007Conference Paper [["dc.bibliographiccitation.firstpage","339"],["dc.bibliographiccitation.issue","4"],["dc.bibliographiccitation.journal","Annals of Anatomy - Anatomischer Anzeiger"],["dc.bibliographiccitation.lastpage","341"],["dc.bibliographiccitation.volume","189"],["dc.contributor.author","Ihlow, Dankmar"],["dc.contributor.author","Kubein-Meesenburg, Dietmar"],["dc.contributor.author","Fanghaenel, Jochen"],["dc.contributor.author","Thieme, Kirsten M."],["dc.contributor.author","Hahn, Wolfram"],["dc.contributor.author","Dathe, Henning"],["dc.contributor.author","Zech, Susanne"],["dc.contributor.author","Naegerl, Hans"],["dc.date.accessioned","2018-11-07T11:05:56Z"],["dc.date.available","2018-11-07T11:05:56Z"],["dc.date.issued","2007"],["dc.description.abstract","Examinations of the curvature morphology of the temporomandibular joints (TMJs) in macerated human skulls yielded that in initial protrusive cranial border motion, parts of the condylar articulating surfaces are only functional under force transmission.

We quantitatively examined the curvature morphology of the tibiotalar articulating surfaces and specified their geometric contact patterns. Methods: Geometrically equivalent cartographic nets were marked on the talar and tibial articulating surfaces of true-to-scale moldings of 20 human ankle joints (intervals of 5 mm) to relate corresponding articulating units of the surfaces. The corresponding contours of the net lines were compared, and the incongruity of articulating surfaces could thus be quantified locally. Results: All tibial sagittal net lines represented circular arcs. Along the sagittal talar net lines, the curvature radii increased medially from anterior to posterior but decreased laterally. Each net line could be approximated by three circular arcs. Examining these three parts of the talar net lines, the anterior sagittal curvature radii increased from medial to lateral, whereas the posterior radii decreased. The tibial and talar transversal net lines were congruent. The articulation surfaces showed a transversal contact line in every dorsal/plantar joint position. The degree of local congruity was solely ascertained by the incongruity of the corresponding sagittal net lines. The maximal degrees of congruity were found laterally for dorsal flexion, laterally/centrally for neutral joint position, and centrally/medially for plantar flexion. Conclusions: By the transversal line contact, the contact area is broadened over the articulating surfaces from lateral to medial. In dorsal flexion, compressive loads are mainly transferred by lateral/anterior zones and in plantar flexion by medial/posterior zones of the articulating surfaces. Reconstruction of the transversal contact line is essential."],["dc.identifier.doi","10.5277/ABB-00462-2015-03"],["dc.identifier.isi","000388303000009"],["dc.identifier.pmid","27840439"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/41745"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wroclaw Univ Technology"],["dc.relation.issn","1509-409X"],["dc.title","The upper ankle joint: Curvature morphology of the articulating surfaces and physiological function"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]Details DOI PMID PMC WOS2011Journal Article [["dc.bibliographiccitation.firstpage","358"],["dc.bibliographiccitation.issue","5"],["dc.bibliographiccitation.journal","Journal of Orofacial Orthopedics / Fortschritte der Kieferorthopädie"],["dc.bibliographiccitation.lastpage","370"],["dc.bibliographiccitation.volume","72"],["dc.contributor.author","Ihlow, Dankmar"],["dc.contributor.author","Dathe, Henning"],["dc.contributor.author","Fanghaenel, Jochen"],["dc.contributor.author","Proff, Peter"],["dc.contributor.author","Naegerl, Hans"],["dc.contributor.author","Hahn, Wolfram"],["dc.contributor.author","Kubein-Meesenburg, Dietmar"],["dc.contributor.author","Thieme, Kirsten M."],["dc.date.accessioned","2018-11-07T08:51:06Z"],["dc.date.available","2018-11-07T08:51:06Z"],["dc.date.issued","2011"],["dc.description.abstract","One way of determining the direction of growth of the mandible is to consider the temporomandibular joint and movement of the mandible as a four-joint gear system, regarding growth then as an extension of the gear system.

A total of 130 lateral cephalograms-before and after orthodontic treatment-were available from 65 adolescent class II patients with open bite or deep bite.

No correlation between the cephalometric data and distances or angles were observed. Although there were no significant differences in the distances, we did note significant differences in all three angles (p < 0.05).

The corresponding local deformation at the interface periodontal ligament-alveolar bone causes a distribution of normal and shearing tension that is thought to be the local stimulus for bone remodeling leading to orthodontic tooth movement. Although researchers have examined initial tooth movement and the biomechanical properties of the periodontal ligament, few have reported human, in-vivo studies. For such examinations, very small tooth displacements must be measured with extremely high resolution and accuracy. Methods: By a highly sensitive goniometer (resolution <0.001 degrees), rotations of premolars in 22 subjects with natural spacing and 14 subjects with pronounced anterior crowding were measured in vivo. The rotations followed sets of pure moment-time functions starting at zero and reaching specified final values within +/- 1.43 Ncm. Results: Usually, thresholds were seen that had to be overcome by moment to produce measurable rotations of the tooth in the mesial or distal direction. The subjects with pronounced anterior crowding showed distinct asymmetry: Thresholds for rotations to the distal direction were significantly higher than for those to the mesial direction. Conclusions: The cases of symmetric thresholds indicated a shear thinning viscosity in the periodontium under increasing moment. In the case of asymmetric thresholds, the findings suggested a mesially directed pretension of the gingival fiber apparatus that might be connected with the mesial drift."],["dc.identifier.doi","10.1016/j.ajodo.2005.11.030"],["dc.identifier.isi","000209810800004"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/35635"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Mosby-elsevier"],["dc.relation.issn","1097-6752"],["dc.relation.issn","0889-5406"],["dc.title","Biomechanical features of the periodontium: An experimental pilot study in vivo"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]Details DOI WOS2007Conference Paper [["dc.bibliographiccitation.firstpage","404"],["dc.bibliographiccitation.issue","4"],["dc.bibliographiccitation.journal","Annals of Anatomy - Anatomischer Anzeiger"],["dc.bibliographiccitation.lastpage","406"],["dc.bibliographiccitation.volume","189"],["dc.contributor.author","Ihlow, Dankmar"],["dc.contributor.author","Kubein-Meesenburg, Dietmar"],["dc.contributor.author","Fanghaenel, Jochen"],["dc.contributor.author","Bernitt, Katrin"],["dc.contributor.author","Hahn, Wolfram"],["dc.contributor.author","Dathe, Henning"],["dc.contributor.author","Sadat-Khonsari, Reza"],["dc.contributor.author","Thieme, Kirsten M."],["dc.contributor.author","Naegerl, Hans"],["dc.date.accessioned","2018-11-07T11:05:57Z"],["dc.date.available","2018-11-07T11:05:57Z"],["dc.date.issued","2007"],["dc.description.abstract","The subject of this study was to analyse how functional parameters of stomatognathic systems are influenced by growth.

In the stance phase (0-20A degrees flexion), the femur rolls backwards over the tibia plateau, while further flexion causes increased gliding. This kinematics is based on the principle of a quadruple joint. The four morphological axes of rotation are the midpoints of the curvatures of the medial and lateral femoral condyles and the medial and lateral tibia plateau. In addition, the medial and lateral compartments are shifted a few millimetres in a sagittal direction, the medial tibia plateau being concave and the lateral plateau convex. In most knee arthroplasties, these factors are not taken into account; instead they are equipped with symmetrical medial and lateral joint surfaces. Thereby, the midpoints of the curvatures of the sagittal contours of the lateral and medial joint surfaces, on the femoral as well as on the tibial sides, create a common axis of rotation which does not allow a physiological roll-glide mechanism. The goal of this study was therefore to report on the biomechanical basis of the natural knee and to describe the development of a novel knee endoprosthesis based on a mathematical model. The design of the structurally new knee joint endoprosthesis has, on the lateral side, a convex shape of the tibial joint surface in a sagittal cross section. Furthermore, from a mathematical point of view, this knee endoprosthesis possesses essential kinematic and static properties similar to those of a physiological TFJ. Within the framework of the authorization tests, the endoprosthesis was examined according to ISO/WC 14243 in a knee simulator. The abrasion rates were, thereby, lower than or at least as good as those for conventional endoprostheses. The presented data demonstrate a novel concept in knee arthroplasty, which still has to be clinically confirmed by long term results."],["dc.identifier.doi","10.1007/s00113-008-1550-5"],["dc.identifier.isi","000263300400005"],["dc.identifier.pmid","19183924"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/17559"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","0177-5537"],["dc.title","A novel knee endoprosthesis with a physiological joint shape Part 1: Biomechanical basics and tribological studies"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]Details DOI PMID PMC WOS2007Conference Paper [["dc.bibliographiccitation.firstpage","336"],["dc.bibliographiccitation.issue","4"],["dc.bibliographiccitation.journal","Annals of Anatomy - Anatomischer Anzeiger"],["dc.bibliographiccitation.lastpage","338"],["dc.bibliographiccitation.volume","189"],["dc.contributor.author","Zech, Susanne"],["dc.contributor.author","Fricke, Julia"],["dc.contributor.author","Fanghaenel, Jochen"],["dc.contributor.author","Dathe, Henning"],["dc.contributor.author","Ihlow, Dankmar"],["dc.contributor.author","Thieme, Kirsten M."],["dc.contributor.author","Kubein-Meesenburg, Dietmar"],["dc.contributor.author","Proff, Peter"],["dc.contributor.author","Gedrange, Tomas"],["dc.contributor.author","Naegerl, Hans"],["dc.date.accessioned","2018-11-07T11:05:55Z"],["dc.date.available","2018-11-07T11:05:55Z"],["dc.date.issued","2007"],["dc.description.abstract","Morphological. parameters of the temporomandibular joint (TMJ) of Cercopithecus mona were analyzed by sagittal medial/lateral slicing of the entire joint.
