Abstract
Introduction: Gingival biotype has critical importance in determining the length and stability of miniscrew. This study was conducted to assessthickness of buccal attached gingiva at common miniscrew insertion sites in orthodontic patients with different facial types.
Material and Method: 60 orthodontic patients with no systemic disease and no transversal skeletal discrepancy were included in this study. All the subjects having healthy periodontium were considered. All subjects were within the age range of 18-25 years. Subjects were divided into three groups based on their Frankfort mandibular plane angle, namely; High angle, Normal angle, low angle respectively. Trans gingival probing was used to measure the thickness of the buccal attached gingiva. Endodontic spreader and digital vernier caliper were used to assess the gingival thickness. All measurements were recorded by the same examiner and data will be statistically analyzed.
Result: Results showed no statistically significant difference among the gingival thickness values of different facial types. No statistically significant difference found between male and female except in maxillary posterior region where males showed thicker biotype when compared to females.
Conclusion: No statistically significant difference was found between the thicknesses of maxillary and mandibular posterior buccal approximal attached gingiva and different facial types.
Keywords: Miniscrew, attached gingiva, vernier caliper, spreader.
