BACKGROUND
There are many causes and reasons associated with fractures of complete dentures. The present study assessed case of complete denture fracture.
MATERIALS AND METHODS
One hundred and fifty complete denture wearers reported to the department of prosthodontics for correction of complete denture fracture were examined carefully. The factors such as retention, stability, and occlusal errors were recorded. Cause of denture fracture was recorded too.
RESULTS
Out of 150 patients, males were 80 and females were 70. The site of fracture was incisor area in 25, canine area in 30, midline in 50, molar area in 10, and maxillary tuberosity/retromolar pad area in 35 cases. The etiology of denture fracture was accidental fall in 42, poor fit in 28, poor occlusion in 40, material breakage in 25, and acrylic base defect in 15 cases. The difference was statistically significant ( < 0.05).
CONCLUSION
Most common cause of denture fracture was accidental fall, poor fit, poor occlusion, and material breakage.
背景
全口义齿折断有多种相关原因。本研究评估了全口义齿折断的病例。
材料与方法
对150名因全口义齿折断前来口腔修复科就诊的全口义齿佩戴者进行了仔细检查。记录了诸如固位、稳定和咬合错误等因素。义齿折断原因也进行了记录。
