The first few days following the insertion of complete dentures are critical for the patients since they are struggling to adapt to their new dentures. This study aimed to evaluate the most common locations of traumatic ulcerations, their frequency and also the duration and number of adjustment visits required to achieve patient comfort fol-lowing placement of complete dentures.
Sixty patients were selected from edentulous patients referring to a removable prosthodontics department. Complete dentures were fabricated for the patients. After placement of dentures, all the patients were evaluated from the day after placement until patient comfort was achieved. Descriptive analysis was performed and chi-squared test was used to evaluate the associations between lesions, post-insertion visits and gender.
A total of 85.8% of patients required denture adjustment because of mucosal injuries during their first visit fol-lowing denture placement. Maxillary and mandibular dentures did not require further adjustments after fourth and sixth visits, respectively. No significant differences were detected between males and females in the number of mucosal injuries in the anatomical areas evaluated in the maxilla and mandible using Fisher's exact test (P > 0.05). Furthermore, the number of mandibular dentures requiring adjustments was significantly higher than maxillary dentures in all the post-insertion ap-pointments (P < 0.001).
Since most mucosal injuries are located in the vestibule, adequate extension of denture flanges, especially during border molding, and use of pressure indicators that reveal over-extended borders, play an important role in decreas-ing mucosal injuries and improving patient comfort following complete denture placement.
全口义齿初戴后的头几天对患者来说至关重要，因为他们要努力适应新义齿。本研究旨在评估创伤性溃疡最常见的发生部位、其发生率，以及全口义齿初戴后达到患者舒适所需的复诊持续时间和次数。
从前往可摘局部义齿科就诊的无牙颌患者中选取60例。为这些患者制作全口义齿。义齿戴入后，对所有患者从戴入后的第二天开始评估，直至患者感到舒适。进行描述性分析，并使用卡方检验评估病变、戴入后复诊次数与性别的关联。
总共85.8%的患者在义齿戴入后的首次复诊时因黏膜损伤需要调整义齿。上颌义齿和下颌义齿分别在第四次和第六次复诊后无需进一步调整。使用Fisher精确检验，在上颌和下颌评估的解剖区域中，男性和女性的黏膜损伤数量未检测到显著差异（P>0.05）。此外，在所有戴入后的预约复诊中，需要调整的下颌义齿数量显著高于上颌义齿（P<0.001）。
由于大多数黏膜损伤位于前庭，义齿基托边缘的充分伸展，尤其是在边缘整塑期间，以及使用能揭示边缘过度伸展的压力指示物，在减少黏膜损伤和提高全口义齿初戴后患者舒适度方面发挥着重要作用。
