Abstract

Treatment protocol in orthodontic treatment is based on the dentoalveolar and facial profile patients. The objectives of this
study were (1) to compare dentoalveolar profile changes in skeletal malocclusion types after four orthodontic treatment
types, nonextraction, two upper first premolars, two lower first premolars extraction, and four first premolars extraction;
(2) to compare dentoalveolar profile changes after orthodontic treatment within skeletal malocclusion types; (3) to
compare dentoalveolar profile changes within orthodontic treatment types. The study was conducted in Dental Hospital,
Faculty of Dentistry-Airlangga University. Forty eight patients (females, between 17-32 years) who fulfilled the inclusion
criteria were selected. Data was analyzed using ANOVA test. The results showed that dentoalveolar profile was
significant difference between without extraction and four first premolars extraction (p<0.05), except for variables NB-L1
and IMPA. The dentoalveolar facial profile changes were significant difference within malocclusion types after
orthodontic treatment (p<0.05). In Conclusion, the extraction in orthodontic treatment type had a great variation of
dentoalveolar profile changes after orthodontic treatment depends on malocclusion types.
