Early Treatment of Malocclusion: Is it About Function or Morphology?
Early treatment in orthodontics is still the subject of debate and controversy regarding cost-effectiveness in the analysis of functional and psychosocial benefits. Diagnostics for early orthodontic treatment should evaluate the morphology of the dentition, particularly the transverse occlusal relationship, as well the irregular orofacial functions. Tongue posture and function (swallowing pattern) should especially be noted, since irregular orofacial functions and sucking habits have a direct effect on the developing occlusion and an indirect effect by changing the swallowing pattern. Every clinical examination in children with sucking habits should include assessment of orofacial functions, especially the tongue posture and function, which was found to be an important factor in the etiology of unilateral posterior crossbite development. The assessment of orofacial functions is important procedure in screening of children for early orthodontic treatment.
Recognize and identify the etiology of unilateral posterior crossbite and distinguish between genetic and environmental factors for this malocclusion development
Assess irregular orofacial functions in children with unilateral posterior crossbite using ultrasonography
Describe the protocol for early orthopedic treatment of unilateral posterior crossbite
Serial Extraction: Do We Do That Anymore?
This lecture will describe serial extraction and identify its advantages and disadvantages. Tooth movements secondary to serial extraction will be described from recent research findings. The clinical application of serial extraction will be described using case histories. The impact of serial extraction on stability , facial change and treatment time will be reviewed, and serial extraction to patients with missing premolars will be discussed.
Identify when serial extraction is indicated
List the treatment sequence with advantages and disadvantages for serial extraction
Describe tooth movement involved with serial extraction
