Introduction/Background: The infrazygomatic crest is considered an important area for a successful mini-implant insertion. The objective of this research is to gain a better understanding of the infrazygomatic crest anatomy for a safe and efficient placement of mini-implants.
Materials and methods: A total of 26 CBCT scans from adult patients were analyzed. A axial CT slice was used to precisely identify the apex of the mesiobuccal root, distobuccal root, and furcation of each permanent first maxillary molar and to analyze bone depth above each root.
Results: The highest average bone depth was located just above the apex of the mesiobuccal (MB) root and the distobuccal (DB) root with an average values of 12.24 mm and 12.31 mm respectively.
Conclusion: The best bone depth was available above the root apices of the mesiobuccal and distobuccal roots. It is essential to acknowledge the significant anatomical differences at the infrazygomatic crest among individuals, highlighting the importance of personalized approaches in orthodontic treatments.
