Aim of the course
The course is designed to provide detailed information regarding the human craniofacial growth and development. It will cover the following topics. (1) The concepts of craniofacial growth and development. (2) The prenatal craniofacial period. (2) The postnatal period. (3) The development of dentition. (4) The application of craniofacial growth data in clinical orthodontics.
Course Contents
1. Basic concepts of growth and development.
2. Prenatal growth of the cranium, facial and oral structures
3. Mechanisms of craniofacial growth, cartilage, bone and muscles
4. Changing concepts and hypotheses of craniofacial growth.
5. Postnatal growth of the craniofacial complex.
6. Development of the dentition and occlusion and dental arch development.
7. Growth rotations, growth prediction and maturity indicators.
8. Maturational and aging changes.
9. Craniofacial anomalies and syndromes and pathology of the cranial base.
10. Clinical applications of craniofacial growth.
a) Knowledge and understanding
a.1. Define the basic growth concepts (area relocation, appositional growth, displacement, remodeling, resorption, deposition, fusion).
a.2. Recall the growth and development of the main craniofacial components: cranial base, maxilla, and mandible, and their interrelationships at different stages of growth.
a.3. Identify the tissues involved in facial growth: bone, cartilage and muscle.
a.4. Underline the differences in facial form and patterns.
a.5. Review the major deformities of growth.
a.6. Express why and how knowledge of facial and somatic growth and development is critical to early treatment of malocclusion through prevention, interception, or early correction of interferences with normal development that lead to malocclusion.
b) Intellectual Skills
b.1. Illustrate the basic tissues involved in craniofacial growth, particularly bone and cartilage.
b.2. Categorize the different locations and types of cartilage in the head.
b.3. Differentiate between the endochondral and intramembranous modes of bone formation, and the facial bones involved in each modality.
b.4. Debate the basic craniofacial growth concepts including area relocation, bone displacement, processes of appositional growth and depositional resorption, and issues of modeling, remodeling, and the V principle.
b.5. Demonstrate sites and mechanisms of growth of the cranial base, the influence of this growth on the position of the growing maxilla and mandible, and the factors that lead to anomalies of cranial growth.
b.6. Sketch the patterns and mechanisms of maxillary growth in all 3 planes of space, and the influence of sutural growth on maxillary development
b.6. Debate the various theories of growth, including Moss’s functional matrix and related control processes of facial growth.
b.7. Question how craniofacial development translates at the level of the dentition and occlusion.
c) Professional and Practical Skills
The students should be able to manage deviations from normal development that represent or may lead to facial deformities, including genetic components.
d) General and transferable skills
The students should be able to manage deviations from normal development that represent or may lead to facial deformities, including genetic components.
