IMPLANT AN ABSOLUTE ANCHORAGE: A CASE OF IMPLANT SUPPORTED RETRACTION OF BIMAXILLARY DENTOALVEOLAR PROTRUSION
Author: Eshan Awasthi, Narendra Sharma, Abhilasha Goyal, Deoashish Gupta, Vaibhav Khare
Studies have shown that orthodontic mini-implants serve as an important anchorage method, for orthodontists at all treatment stages, reducing the patient`s compliance and achieving more predictable results. Implant serves as an absolute anchorage taking anchorage from skeleton with no reactionary force on posterior teeth during reaction
Aim: This case report describes the treatment of a 31-year-old female who had incompetent lips with severe bimaxillary dentoalveolar protrusion.
Methodology: The preferred treatment alternative for such malocclusion is extraction of four first premolars and utilization of extraction spaces retraction of the anterior teeth. To maintain the extraction space, maximum anchorage is required. Mini-implants were used for absolute anchorage to get a good facial profile.
Conclusion: Post treatment the profile improved, competency of lips was achieved and cephalometric superimposition revealed that no anchorage loss was seen with all extraction space being utilized for retraction. Hence implant serves as an effective tool as an absolute anchorage
Keywords: Implant, Miniscrew, Absolute anchorage
