Demand for dental health care is increasing,
especially in the Orthodontic field. The main objective of orthodontic
treatment is to restore malocclusion conditions. Malocclusion causes aesthetics
issues for the patient’s face and several discomforts like a difficulty in
breathing or swallowing or speaking. If not repaired, a malocclusion could lead
to other diseases, such as a greater risk of perforated teeth, gum irritation
and temporomandibular disorder or pain in the lower jaw. Malocclusion can be
remedied by Orthodontic Brackets. This research aim is to fabricate an
orthodontic bracket that is suitable for the teeth structure of the Indonesian
people. The fabrication method uses an Investment Casting process. The results
show that orthodontic brackets have been successfully produced within an
acceptable geometric tolerance, with the exception that surface finish quality
has to be improved.
