TL;DR: Despite the compensatory movements exhibited by these individuals with Class III malocclusions, normal /s/ production was found in only one of the twelve subjects studied.
Abstract: In this investigation a group of individuals with Angle Class III malocclusions were studied radiographically to determine their tongue posture at rest and during phonation of /s/. Their speech and hearing was also evaluated. All of the subjects had normal hearing, while eleven of the twelve in the group showed some degree of sibilant distortion. At rest, these Class III subjects demonstrated a tongue posture that was lower than normal and more retruded. During the phonation of /s/ these individuals also demonstrated retrusion of the tongue in an apparent attempt to achieve a normal relationship of the tongue tip to the maxillary anterior teeth, an increased amount of mandibular depression, and a greater than normal distance between the tongue tip and the mandibular anterior teeth. Despite the compensatory movements exhibited by these individuals with Class III malocclusions, normal /s/ production was found in only one of the twelve subjects studied. This is in contrast to the successful compensations that result in normal /s/ production seen in a great number of individuals with a Class III, Division 1 malocclusion, as demonstrated by Subtelny, Mestre and Subtelny.

TL;DR: The author proposes a contemporary definition of the line of occlusion: "a distinctively individual line at the incisobuccal contact, with a location, position, and form to which the teeth must conform to be in normal Occlusion".
Abstract: With the re-evaluation of the concept of the "line of occlusion" the author proposes a contemporary definition: "a distinctively individual line at the incisobuccal contact, with a location, position, and form to which the teeth must conform to be in normal occlusion." In other words, it is that position which the teeth must occupy to be in stability and harmony with each other and with all other anatomic structures.

TL;DR: The results show that the space available for the permanent dentition can be estimated in advance of treatment based on the patient's own skeletal measurements, thus minimizing unnecessary extractions, relapse, and extended treatment time due to errors in diagnosis.
Abstract: The tendency toward relapse in intercuspid width has been examined with those cases having final intercuspid width less than 27 mm showing significantly less relapse than those cases with final intercuspid width of 28 mm or more. The point of contact between the cuspid and first premolar has been introduced as a key point on the arch, determining arch width. An individualized norm has been derived for this measurement as a function of the patient's tooth size, facial pattern, and other variables based upon stable normal occlusions in treated cases. Those cases expanded to a dimension exceeding the norm by more than 1 mm showed a greater propensity toward relapse. The group following the norm was significantly more stable than the over- and underexpansion groups at the .025 significance level. An individual norm for intermolar width based upon the patient's facial pattern (using frontal and lateral X-rays) has been established. Cases showing relapse showed considerably less space between the lower molar and the JAG plane, and greater lower face height than stable cases. The results show that the space available for the permanent dentition can be estimated in advance of treatment based on the patient's own skeletal measurements, thus minimizing unnecessary extractions, relapse, and extended treatment time due to errors in diagnosis.
TL;DR: It has been demonstrated that there are reliable methods of predicting the ultimate position of the lower incisor and the soft tissue, but the concept of treating this tooth to any one number for every individual was not supported by the evidence.
Abstract: It has been demonstrated that there are reliable methods of predicting the ultimate position of the lower incisor and the soft tissue. However, the concept of treating this tooth to any one number for every individual was not supported by the evidence. An optimum system would allow the clinician to select and combine factors from all methods and arrive at a balance of esthetics, function, and stability, obtaining a suitable compromise for his individual patient. This is undoubtedly attempted intuitively by many experienced clinicians.

TL;DR: This work was supported in part by PHS Grants DE-02172-13 and IR231-DE-453701 and image enhancement performed under the auspices of the Energy Research and Development Administration under Contract W7405-ENG-36.
Abstract: Quantification of cephalometric X-rays requires the use of hand tracings of the structures to delineate points, lines, and angles. The structures, especially soft tissue, are often obscure and are therefore approximated. Recent biomedical application of image enhancement by digital computer promises a method whereby landmarks in the cranium are more clearly defined. Development of this technique will enable a more extensive and accurate utilization of cephalometric radiographs for diagnostic and research purposes.

TL;DR: The use of a lower headgear-yoke-Class II mechanism on an average works faster than a maxillary headgear and the HGY-II mechanism is indicated when most permanent teeth are available and thus the therapy can be completed in one treatment period.
Abstract: The use of a lower headgear-yoke-Class II mechanism on an average works faster than a maxillary headgear The distal tipping of the molars is greater with HGY-II which may be the result of the quicker tooth movement The speed of distalization is probably due to the effect of the constant force of the Class II elastics An orthopedic change on the maxilla could be seen if one can draw any conclusions from a change of only 1 degrees A reduction of the SNA angle and a slight clockwise rotation of the palatal plane was noticed These results agree with earlier investigations about cephalometric changes with headgear therapy We have come to the conclusion that both methods are indicated We use the upper headgear especially at a time when a complete therapy is not possible because of noneruption of the permanent teeth The HGY-II mechanism is indicated when most permanent teeth are available and thus the therapy can be completed in one treatment period
TL;DR: Multivariate analysis of craniofacial profiles demonstrated the complex interaction between the brain case and facial skeleton during growth and between various occlusal categories.
Abstract: Multivariate analysis of craniofacial profiles demonstrated the complex interaction between the brain case and facial skeleton during growth and between various occlusal categories. Only by investigating craniofacial growth data still further will it be possible to establish normative standard growth patterns that can withstand critical scientific appraisal.
