Rapid palatal expansion have been widely used with predictable clinical results. Recently, orthodontist have successfully used mini implant assisted rapid palatal expander to achieve more skeletal expansion. Based on the knowledge of load system and biology, clinical effects and problems with the mini-implant assisted rapid palatal expansion will be presented.
Identify the pros and cons of mini implant assisted rapid palatal expansion.
Identify the limit of maxillary palatal expansion.
Currently there are increasing number of studies that demonstrate that substantial reductions in orthodontic treatment time are achievable. Corticotomies, vibration, laser, electric current and controlled localized injury have been suggested to increase the basal metabolic rate of the hard and soft tissues which then reduces treatment time. The suggested mechanisms to enhance tooth movement seem to have their basis in tissue level histological events. This lecture will outline basic biologic processes that could be altered and thereby be targeted to achieve expedited tooth movement.
Recognize the physiologic processes and homeostatic mechanisms in bone.
Recognize how bone biologic can be altered to produce expedited tooth movement.
Distinguish purported mechanisms for tooth movement that have a scientific basis and those that do not.
