TOPIC: ARTICULATORS AND FACEBOWS

🎯 KEY FACTS

🔹Arcon Articulators contain the condylar guidance within the upper member and the condylar elements within the lower member.

🔹Functional Articulation is the occlusal contact of the maxillary and mandibular teeth during mastication and deglutition.

🔹Bennett Angle is formed between the sagittal plane and the orbital path (horizontal lateral condylar path). Average Bennett angle is between 7.5º and 12.8º.

🔹Bonwill Triangle is a 4-inch equilateral triangle bounded by lines connecting the contact points of the incisal edges of mandibular central incisors to each condyle and from one condyle to the other.

🔹Frankfort Horizontal Plane (Fh Plane) is a horizontal plane which is established by joining the line between the lowest point on the margin of the orbit to the highest point on the margin of the auditory meatus.

🔹Bonwill Triangle was first given by W.G.A. Bonwill in 1858.
