TL;DR: The advancing tooth morphogenesis is punctuated by transient signaling centers in the epithelium corresponding to the initiation of tooth buds, tooth crowns and individual cusps, which could have allowed the evolutionary divergence of tooth shapes among the four tooth types.
TL;DR: It is completely practical as a treatment-planning procedure to approach the proposed orthodontic changes from a soft-Tissue analysis perspective, making changes only to the point where the best possible soft-tissue profile is established, and then compute the tooth movement necessary to develop ideal profile relationships.
TL;DR: The role and significance of lip posture in orthodontics, particularly as applied to trea,tment planning, is considered, and a detailed description of the relaxed-lip and closed-lip positions will be presented.
TL;DR: It is suggested that extraction of the primary canine is the treatment of choice in young individuals to correct palatally ectopically erupting maxillary canines provided that normal space conditions are present and no incisor root resorptions are found.
Abstract: The effect of extraction of the primary canine on palatally erupting ectopic maxillary canines was analysed. There were 46 consecutive ectopic canines, in 35 individuals, aged 10.0–13.0 years (mean age 11.4 years) at the time of discovery of the ectopic eruption. All cases showed no or minor space loss. After extraction of the primary canine, the children were investigated clinically and radiographed at 6-month intervals for up to 18 months.
In 36 of the 46 canines (78%) the palatal eruption changed to normal; 23 already showed improved positions after 6 months and 13 after 12 months. No new cases normalized after 12 months.
We suggest that extraction of the primary canine is the treatment of choice in young individuals to correct palatally ectopically erupting maxillary canines provided that normal space conditions are present and no incisor root resorptions are found.
TL;DR: The similarity between the biomechanical properties of endodontically treated teeth and their contralateral vital pairs indicates that teeth do not become more brittle following endodentic treatment.
