Does low gonial angle affect the Amount of Bone Loss Around implant in the posterior mandible?

Background: The purpose of this study was to investigate whether there is a role the low gonial angle on marginal bone resorption around implants placed in posterior mandible. Methods: This retrospective study, including 20 patients with 46 followed 36 months were inserted toothless area. Patients without systemic disease included study. measured panoramic x-ray; more than 1250were classified as high angle, and those less 1200 group. Mesial distal implant angulation occlusal plane via Image J software (National Institutes Health; version 1.5i, USA). Independent samples t-test used compare variables between groups. Results: mean (MBL) 0.27±0.16 mm for mesial side 0.27±0.13mm LGA In HGA group, MBL 0.77±0.28mm 0.71±0.27mm side. There no statistical significance groups regarding resorption. However, correlated Conclusion: result that not directly risk factor dental implant. should be perpendicular possible
