What does occlusal plane mean in dentistry?
Medical Definition of occlusal plane : an imaginary plane formed by the occlusal surfaces of the teeth when the jaw is closed.
What is the name for the curve of the occlusal plane?
Curve of Spee
In anatomy, the Curve of Spee (called also von Spee’s curve or Spee’s curvature) is defined as the curvature of the mandibular occlusal plane beginning at the canine and following the buccal cusps of the posterior teeth, continuing to the terminal molar.
What is posterior occlusal plane?
Posterior occlusal plane—a line drawn from the cusp tip of the upper second premolar to the midpoint of the upper second molar at the occlusal surface.
How do you fix an occlusal plane?
Conclusions. Maxillary occlusal plane canting caused by extruded teeth can easily be corrected with normal orthodontic appliances by using skeletal anchorage with miniscrews. Facial asymmetry with a canted maxillary occlusal plane can be treated with only mandibular surgery, thus avoiding maxillary surgery.
Which plane is parallel to occlusal plane?
Traditionally occlusal plane is made parallel to inter-pupillary line anteriorly and camper’s line posteriorly by repeated checking of occlusal rim plane in patients mouth with fox plane or numerous other devices and readjustments until the desired occlusal plane orientation is achieved .
Why is curve of Spee important?
This normal occlusal curvature is required for an efficient masticatory system. Exaggerated curve of Spee is frequently observed in dental malocclusions with deep overbites.  Such excessive curve of Spee alters the muscle imbalance, ultimately leading to improper functional occlusion.
What is curve of Wilson in dentistry?
The curve of Wilson is the across arch curvature or posterior occlusal plane. Arc of the curve, which is concave for mandibular teeth and convex for maxillary teeth are defined by a line drawn from left mandibular first molar to right mandibular first molar.
What is the role of the curve of Spee?
Can occlusal cant be corrected?
A right side up occlusal cant should be corrected by an Yin-Yang archwire with a right side down and left side up orientation at the anterior. A left side up occlusal cant should be corrected by an Yin-Yang archwire with a left side down and right side up orientation at the anterior [Figure 1].
What causes canted maxilla?
Trauma. Injuries, especially childhood ones, to your teeth, gums, or lips will affect the appearance of your smile. Heavy grinding is also a possible culprit. If any of these factors affect a part of your smile more than other parts, they could lead to a canted smile.
What is the Frankfort horizontal plane?
In profile view, a plane connecting the highest point of the opening of the external auditory canal with the lowest point on the lower margin of the orbit, used to orient a human skull or head so that the plane is horizontal.
What is Christensen phenomenon?
Quick Reference. [C. Christensen, Danish dentist and educator] A gap occurring in the natural dentition or between the opposing posterior flat occlusal rims when the mandible is protruded (posterior open bite). It can lead to instability in full dentures unless compensating curves are incorporated into the dentures.
What is the occlusal plane in dentistry?
11. OCCLUSAL PLANE Occlusal plane or plane of occlusion refers to a imaginary surface that theoretically touches the incisal edges of the incisors and the tips of the occluding surfaces of the posterior teeth. www.indiandentalacademy.com 12.
Is occlusal plane canting of 0º and 2º esthetically acceptable?
Conclusions: Occlusal plane canting of 0º and 2º were evaluated as esthetically acceptable by the three groups. The 4º occlusal plane cant was evaluated more negatively by orthodontists than by general dentists and laypersons. All three groups placed the 0º image in first place of esthetic acceptability, 2º in second place and 4º in third.
How do Orthodontists evaluate occlusal plane Cant?
The 4º occlusal plane cant was evaluated more negatively by orthodontists than by general dentists and laypersons. All three groups placed the 0º image in first place of esthetic acceptability, 2º in second place and 4º in third. Orthodontists put the 0º image in first place with significantly greater frequency than laypersons.
What is an occlusal line in dentistry?
13. OCCLUSAL LINE By definition a line is one which connects two points in space Occlusal line refers to the line connecting the overlap of the first permanent molars and incisors In orthodontics the terms occlusal plane and occlusal line are used interchangingly and can mean one or the other www.indiandentalacademy.com 14.
