Factors Influencing Superimposition Error of 3D Cephalometric Landmarks by Plane Orientation Method Using 4 Reference Points: 4 Point Superimposition Error Regression Model

Factors Influencing Superimposition Error of 3D Cephalometric Landmarks by Plane Orientation Method Using 4 Reference Points: 4 Point Superimposition Error Regression Model

Superimposition has been used as a method to evaluate the changes of orthodontic or orthopedic treatment in the dental field. With the introduction of cone beam CT (CBCT), evaluating 3 dimensional changes after treatment became possible by superimposition. 4 point plane orientation is one of the simplest ways to achieve superimposition of 3 dimensional images. To find factors influencing superi...

Cephalometric Superimposition

His famous dissertation, published in 1947, The Face in Profile. An Anthropological X-ray Investigation on Swedish Children and Conscripts, is an outstanding contribution. That monograph became the classic example for numerous scholars to follow so that, 25 years later, a second printing was necessary. research fellow and guest lecturer at Northwestern University in Chicago, Illinois. In 1958 h...

A preliminary assessment of cephalometric orthodontic superimposition.

The superimposition of cephalograms is a valuable tool in orthodontics. In children this task is complicated by the fact that growth changes in the reference structures used in superimposition should be taken into consideration. In this study a new method of superimposition of cephalograms taken in the natural head position (NHP) was compared with Viazis' cranial base triangle and a reference g...

A New Approach to Fuzzy Location of Cephalometric Landmarks in Craniofacial Superimposition

Craniofacial superimposition is the second stage of a complex forensic technique that aims to identify a missing person from a photograph (or video shot) and the skull found. This specific task is devoted to find the most appropriate pose of the skull model to be projected onto the photograph. The process is guided by a number of landmarks identified both in the skull (craniometric landmarks) a...
