Early Interceptive Treatment of Impacted Teeth Utilizing CBCT and the Frontal Analysis. Presenter: Brad Edgren DDS/MS The Fundamental Objectives of Early Intervention: • Normalization of Skeletal Dysplasias and Asymmetries • Developing jaw size to encourage the proper eruption of the permanent teeth • Improvement of Occlusal Function • Intervention and termination of recalcitrant habits (i.e. thumb and finger sucking) ! • Utilization of future Growth • Recognition of excessive growth, i.e. the mandible Advantages of Early Orthodontic Intervention: • Reduces tooth extractions • Reduces the incidence of the impaction of teeth (e.g. Canines) • Reduces the possibility of Orthognathic surgery • Reduces the incidence of Temporomandibular Disorders • Children at age 7 are more cooperative and eager • The dentofacial skeleton is more receptive to maxillary expansion ! • Growth in some females is completed surprisingly early (age 10) Keys to Early Intervention with Dental Impactions: • Clinical Exam • Radiographic Imaging • Lateral and Frontal Cephalometric Analyses • Growth Analysis • Maxillary Expansion should be always considered - hence the need for the Frontal analysis • Diligent monitoring of all erupting teeth • Phase I treatment is not complete until the impacted teeth have erupted or are erupting normally • Radiographic Imaging at the end of Phase I treatment ! ! ! ! ! ! • Referral to an Oral Surgeon as necessary - the earlier is better Benefits of the Frontal Analysis: • Detect Skeletal Asymmetries • Evaluation of the Maxillary and Mandibular Skeletal widths • Evaluation of Dental Arch widths • Evaluation of Nasal widths • Turbinate enlargement evaluation • Angulation and Position of Impacted teeth • Dental midlines compared to Skeletal midlines • Occlusal cants ! ! • Pathology References: Edgren B.
