Maxillary deficiency is one of the common problems in orthodontic patients and is usually associated with
bilateral or unilateral posterior crossbite, narrow nasal cavity, and crowding. Maxillary expansion is the best
possible treatment to correct maxillary deficiency. The aim of the study was to quantitatively assess the different
types of expansion devices used and also to study the association between the type of appliances used and age
distribution. This was a retrospective cross sectional study conducted in the Department of Orthodontics,
Saveetha Dental College, Chennai. Records of patients who underwent maxillary expansion over a period of 10
months from June 2019 to March 2020 were analysed and the type of appliance used for expansion was noted
and grouped accordingly. Total of 13 records were selected based on the selection criteria. Percentage
calculation for each type of appliance used was calculated using SPSS software version 20.0 for Windows. Quad
helix was the most common appliance used with a percentage of about 30.77%. HYRAX was used for 23.06% of
patients who required expansion. Removable appliances with Jack screw, Jockey archwire expansion, MARPE
and SARPE were used for 15.38%, 15.38%, 7.69% and & 7.69% respectively. The appliances were selected based
on the pre-treatment condition, age of the patient, risk benefit ratio and technical skills of the clinician.
