Summary
Maxillary space relations during tooth eruption are key. Findings suggest upper third molar extraction can be delayed until after age 18, allowing for continued jaw growth.
Area of Science:
- Dental Anthropology
- Craniofacial Development
- Orthodontics
Background:
- Understanding maxillary space dynamics is crucial for predicting tooth eruption patterns.
- Maxillary growth and tooth development timelines influence the potential for proper alignment of permanent dentition.
Purpose of the Study:
- To quantify spatial relationships within the maxilla during the eruption of upper molars.
- To analyze the correlation between maxillary growth and the timing of permanent molar emergence.
Main Methods:
- Measurement of spatial distances on 154 human skulls across a developmental spectrum.
- Age determination based on dental development stages.
- Qualitative interpretation of comparative data.
Main Results:
- Sufficient space for the first permanent molar exists shortly after primary dentition, though eruption is delayed.
- The second permanent molar erupts upon space availability, typically around 12-13 years.
- The maxilla demonstrates growth potential even after third molar eruption, accommodating teeth until approximately age 17.
Conclusions:
- Upper third molar (wisdom tooth) extraction may be postponed until after age 18.
- Continued maxillary growth supports potential correct eruption of wisdom teeth.
- Premature extraction of maxillary wisdom teeth due to perceived space deficiency may be avoidable.

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...

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

01:22Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

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,...
