Depending on the age of the patient, bone-borne mechanics utilising mini-implants and miniplates can be used for either orthopaedic or orthodontic applications. Currently, the alveolar process is the most preferred insertion site. However, due to the varying bone quality and the risk of root contact, the survival rate of implants inserted in the alveolar ridge is far from satisfactory. Other regions such as the anterior palate and the mental region provide much better conditions for the insertion and stability of skeletal anchorage devices, as the amount and quality of the available bone is far superior. Mini-implants in the anterior palate with different types of abutments and connectors allow the construction of a large variety of anchorage reinforcing appliances. Additionally, utilising mini-implants in the anterior palate and miniplates in the mental region eliminates the risk of root injury and removes them from the path of tooth movement. Clinical problems, recent advances and research pertaining to the use of skeletal anchorage will be presented.
After this lecture you will be able to:
List the Pros and Cons of different insertion sites for mini-implants and miniplates;
Recognize the hard and soft tissue conditions to easily insert a mini-implant in the palate;
Design optimal TAD borne mechanics based on the clinical objective.
