Assessmentof MaxillaryBone Density forOrthodontic Mini-Implant Placementwith Respect to Different Growth Patterns-Cone-Beam Computed Tomography

Introduction: - This investigation sought to ascertain whether the density of bone in the interradicular regions was impacted by three distinct growth patterns (hyodivergent, normodivergent, and hyperdivergent). Method: - The Department of Orthodontics and Dentofacial Orthopaedics at Jaipur Dental College coordinated the CBCT test for this retrospective study with the Oral Radiology Department. This study included a total of 30 participants (age range: 15- 25 years) seeking orthodontic treatment were recruited from the orthodontic department of Jaipur Dental College for the CBCT study. 10 samples of each - Hyperdivergent, hypodivergent and normodivergent growth pattern and then we had evaluated and compared the measurements between the maxillary canine and first premolar and between the maxillary 2nd premolar and 1st molar. Results: - A statistically significant difference (p<0.01) was observed in the values between the groups for the canine and first premolar, as well as the second premolar and first molar, which had greater values in the hypodivergent growth pattern. All pairs of groups showed a statistically significant difference (p<0.01, 0.05) in values, with the exception of the canine and first premolar between the normodivergent and hyperdivergent groups, and the second premolar and first molar between hypodivergent and normodivergent groups, where there was a statistically non-significant difference (p>0.05). Conclusion: - People with the hyperdivergent facial type usually have less dense buccal cortical bone in the maxillary alveolar processes as compared to people with other facial types. To avoid mini-implant loss due to insufficient initial stability or implantation slippage, doctors must recognize and take into consideration variations in cortical bone density at the locations of mini-implant placement.
