Summary
Palatally displaced canines (PDCs) often occur without skeletal abnormalities, delaying diagnosis. Buccally displaced canines (BDCs) showed no significant skeletal differences from controls, but malocclusion in BDC patients increases treatment motivation.
Area of Science:
- Orthodontics
- Craniofacial Anatomy
- Dental Imaging
Background:
- Maxillary canine impaction is a common orthodontic issue.
- Understanding associated skeletal features aids diagnosis and treatment planning.
Purpose of the Study:
- To investigate and compare skeletal features in patients with palatally displaced canines (PDCG) and buccally displaced canines (BDCG).
- To compare these features against a control group (CG) without impacted canines.
Main Methods:
- Lateral cephalometric radiographs of 108 patients with impacted canines and 121 controls were analyzed.
- Skeletal measurements, including ANB and Steiner angles, were compared between groups.
- Statistical analysis used chi-squared and Fisher's exact tests.
Main Results:
- Control group exhibited increased ANB and retropositioned lower jaw.
- Palatally displaced canine group showed normal skeletal features, primarily Class I, with normal vertical skeletal relationships.
- Buccally displaced canine group showed no significant skeletal differences from controls, except for increased ANB.
Conclusions:
- Palatally displaced canine impaction is often isolated, lacking significant skeletal anomalies, which can delay detection.
- Buccally displaced canines generally do not present with distinct skeletal alterations compared to the general orthodontic population.
- The presence of malocclusion alongside buccally displaced canines enhances patient awareness and motivation for orthodontic treatment.

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:08Overview of the Skull
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
