The Effect of Degree of Crowding on the Time Required to Create Space for Molar Bands by Using Elastomeric Separators

Crowding’s Influence on Separator Efficiency

Abstract

Background and objectives: Dental crowding is one of the most common malocclusions affecting proper alignment and occlusion. During the initial phase of fixed orthodontic treatment, elastomeric separators are routinely placed to create interproximal space, facilitating molar band placement. However, the severity of crowding may influence the efficiency of space creation, thereby affecting treatment progress. Studies have found that elastomeric separators typically create >0.16 mm of interproximal space within 12–24 hours, suggesting placement one day prior to banding is sufficient^1-2Objective:To determine the association between the degree of dental crowding and the time required to create sufficient space for molar band placement by using elastomeric separators. Materials and Methods: Total 60  Patients aged 16-25, receiving orthodontic treatment at Allied Hospital Faisalabad, will be selected using non-probability consecutive sampling. Dental casts will categorize patients into mild, moderate, or severe crowding groups(20 patients each group). Elastomeric separators will be placed in the mesial and distal interproximal areas of the mandibular first molars. Space creation will be assessed on the 2nd, 4th, and 7th days using a leaf gauge, aiming for a minimum of 0.16 mm required for band placement. Data were analyzed using ANOVA / Kruskal–Wallis to compare mean times among the groups. Results: Patients with severe crowding required significantly more time to achieve adequate space compared to those with mild or moderate crowding (p < 0.05). The majority of patients with mild crowding achieved sufficient space within [2 days], whereas those with severe crowding often required 7 days. Some comparisons show elastomeric separators generate adequate space within two days, although types like dumbbell separators may be faster; discomfort and pain typically peak around 24–48 hours^3,4,5 Conclusion: The degree of crowding has a direct impact on the time required for space creation with elastomeric separators. Greater severity of crowding is associated with delayed space achievement, which should be considered when planning the initial phase of orthodontic treatment.
