Explanation:
mandibular trough curve

de boog die wordt gevormd door de mandibulaire tandrichel/tandkassen / door de tandrichel/tandkassen van de onderkaak

Ik ga er hierbij vanuit dat de tandrichel alle tandkassen van de onderkaak om/bevat. Er is enige onduidelijkheid over enkelvoud en meervoud.

Je hebt een tandkas, maar kun je tandkas ook gebruiken voor alle tandkassen bij elkaar? "tandrichel" wel lijkt me. Die tandrichel omsluit een soort "goot", dat zijn de tandholten.

In feite hebben ze het over de 'goot' die alle tandholten van de onderkaak bij elkaar vormen: 'tandholtengoot' Maar die 'goot' wordt begrensd door de tandrichel.

De tandkas (ook tandrichel, tandrif,) is de boog van been waarin de tanden zijn verworteld. De Latijnse term is alveolus dentalis - enkelvoud /dentales - meervoud.

http://nl.wikipedia.org/wiki/Tandkas

Dental alveolus (plural, alveoli) are sockets in the jaws in which the roots of teeth are held in the alveolar process of maxilla with the periodontal ligament. The lay term for dental alveoli is tooth sockets.

IV. Defining the Mandibular Trough

The shape of the trough within the rigid mandible that contains the roots of the mandibular teeth defines an
archform that constitutes a significant constraint on the positioning of the teeth. Definition of this trough mathematically can be accomplished from the scanned or photographic or other data of the patient's lower dental arch. This may be achieved interactively by an operator bringing the mandibular computer model to the screen in an occlusal view from the scanned 3D image of the patient's lower arch. (FIG. 1.) The occlusal plane is derived by identifying three points that include the mesial buccal cusps of the first mandibular molars and the incisal tip of one of the mandibular centrals. (FIG. 2.) These three points can be quickly and accurately selected by an operator on the occlusal view on the computer screen, although pattern recognition software can be used.

The image is rotated so that occlusal plane (O.pl), so defined, is set parallel to screen and so that the arch is symmetrical about a vertical center line with the anterior teeth at the bottom of the screen. A section is made through the data below the teeth. A symmetrical grid is laid over the section and intersections of the grid with the data are selected. (FIG. 4.) The selection may be done automatically or by an operator on the screen. The points define the facial and lingual boundaries of the mandibular trough. (FIG. 5.)

A smooth symmetrical bezier curve is calculated through the midpoints of the grid lines that intersect the trough. (FIG. 6.) Handles at the midline and at the distal ends of the curve allow the operator to control the shape of the bezier curves so that the curve generally follows the midline of the trough between the midpoints. The mandibular trough curve (MT.cv) and the orientation of the occlusal plane provide the reference for the orientation of the individual tooth objects in the setup of the occlusion.

Een andere mogelijkheid zou overigens de Latijnse invalshoek zijn (ik begin meer en meer te denken dat ze 'gewoon' non-standard terminology gebruiken):

processus alveolaris mandibulae / processus alveolaris van de onderkaak

The alveolar process (alveolar bone) is the thickened ridge of bone that contains the tooth sockets or alveoli (alveolus, single) on bones that contain teeth. In humans, the tooth-bearing bones are the maxillae and the mandible.

de boog die wordt gevormd door de processus alveolaris van de onderkaak

Het bot waarin de gebitselementen rusten, wordt de processus alveolaris genoemd. Zodra alle gebitselementen verloren zijn gegaan, genezen de holten in het bot waarin de tandwortels zich bevonden (tandkassen) en worden deze met beenweefsel opgevuld. De processus alveolaris is de ondersteunende basis voor een volledig kunstgebit. In de loop van de tijd wordt de edentate (tandeloze) processus alveolaris kleiner doordat beenweefsel verloren gaat (botresorptie).
