L'obiettivo dell'analisi è determinare l'angolo tra due movimenti all'interno di un sistema articolare, in particolare nell'area di studio della cinematica masticatoria. La comprensione di questi angoli ci consente di: Valutare la dinamica mandibolare: Calcolare gli angoli tra i segmenti mandibolari può fornire informazioni essenziali su come la mandibola si sposta durante il movimento, aiutando a descrivere i pattern del movimento articolare. Modellare la biomeccanica del sistema masticatorio: Gli angoli tra i punti permettono di costruire modelli accurati che simulano il comportamento meccanico del sistema mandibolare, utilizzabili in applicazioni cliniche per diagnosi e trattamenti. Confrontare con angoli standard: Gli angoli misurati possono essere confrontati con valori normali o patologici per identificare eventuali alterazioni nei movimenti mandibolari che potrebbero indicare disturbi dell'articolazione temporomandibolare (ATM). Questo calcolo è fondamentale per fornire una descrizione matematica precisa della cinetica mandibolare e per migliorare la modellazione biomeccanica di strutture orofacciali, cruciali per la diagnosi e l'intervento clinico.
A questo punto non ci resta altro da fare che rappresentare e simulare la posizione spaziale dei punti dinamici marcati dalla figura, quantificandone lo spostamento lineare ed angolare.
