Summary
Maxillary growth significantly increases vertically and in width from infancy to permanent dentition. This study tracked 136 Indian skulls to detail these crucial postnatal developmental changes.
Area of Science:
- Craniofacial anatomy
- Human growth and development
- Anthropology
Context:
- Postnatal development involves significant craniofacial changes.
- Understanding maxillary growth is essential for orthodontics and reconstructive surgery.
- Longitudinal studies provide critical data on developmental trajectories.
Purpose:
- To investigate postnatal developmental changes in the shape and dimensions of the human maxilla.
- To analyze normal maxillary form and growth patterns at different developmental stages.
- To quantify vertical and transverse growth of the maxilla in an Indian population.
Summary:
- Vertical growth of the maxilla (N-Pr) approximately doubled between the pre-eruption and permanent dentition stages.
- Vertical growth of the maxillary corpus and alveolar process (m-Pr) accelerated during tooth eruption.
- Maxillary width increased approximately 1.8-fold from the first to the fifth developmental stage, influenced by orbital growth.
Impact:
- Provides normative data for maxillary development in an Indian population.
- Informs clinical practices in orthodontics, pediatric dentistry, and craniofacial surgery.
- Contributes to the understanding of human craniofacial morphology and its variations.
