Individualized Catenary Curves: Their Relationship to Arch Form and Perimeter
British Journal of Orthodontics, 1996Study casts of the lower arches of 35 children in whom arch alignment was considered acceptable, were examined using a reflex microscope. Arch perimeter was calculated mathematically from a method which required measurement of the mesio-distal widths of the teeth only. This was described as the ‘overlap’ method.

Arch perimeter changes on rapid palatal expansion
American Journal of Orthodontics and Dentofacial Orthopedics, 1990Relationships between changes in arch perimeter and arch width resulting from rapid palatal expansion with the Hyrax appliance were analyzed with the use of dental study casts of 21 adolescent patients. Photographs and measurements from the dental casts obtained before treatment and approximately 3 months after stabilization were used.

Increase in arch perimeter due to orthodontic expansion
American Journal of Orthodontics and Dentofacial Orthopedics, 1991A mathematical model was developed to compare quantitatively the effects of various types of orthodontic expansion on mandibular arch perimeter. Mandibular arch form was modeled with spline interpolation to fit a smooth curve between assigned molar, canine, and incisor positions.

The effects of Fränkel II treatment on arch width and arch perimeter
American Journal of Orthodontics and Dentofacial Orthopedics, 1987Changes in dental arch width and total arch perimeter in 24 Class II, Division 1 patients treated with the Fränkel II appliance were compared with changes in an untreated control group. Measurements were made on pretreatment and posttreatment plaster casts at three points on each of four maxillary and four mandibular teeth.

Lower arch perimeter preservation using the lingual arch
American Journal of Orthodontics and Dentofacial Orthopedics, 1997The purpose of this investigation was to determine whether the placement of a mandibular lingual arch maintained arch perimeter in the transition from the mixed to the permanent dentition, and if so, whether it was effective at preventing mesial migration of first permanent molars, or whether this migration still occurred en masse, by increased lower ...

The catenometer: A reliable device for estimating dental arch perimeter
American Journal of Orthodontics, 1973C orrect alignment of the teeth is a fundamental goal of orthodontic therapy. Thus, the amount of the discrepancy between the total tooth material (mesiodistal widths) present and the dental arch perimeter available to accommodate the teeth is probably the most critical estimate of any of the orthodontic diagnostic procedures.

Mandibular arch perimeter changes with lip bumper treatment
American Journal of Orthodontics and Dentofacial Orthopedics, 1991The effects of lip bumper treatment on the mandibular arch were observed in 32 patients with late transitional and early permanent dentitions. Dental cast measurements were made for arch perimeter, arch length, and arch width. Cephalometric radiographs were used to determine labial tipping of the incisors and distal movement of the molars.
