The aim of the present study was to compare titanium-base and resin-base maxillary complete dentures. In 13 patients with a maxillary complete denture with a titanium base (group I) and in 12 patients with a maxillary complete denture with a resin base (group II), the (a) patient's adaptation to the denture, (b) denture retention and (c) appearance of the mucosa under the denture were evaluated. In all cases, the adaptation was assessed with a questionnaire, while the retention and the appearance of the mucosa were assessed by clinical examination. None of the three measures considered (adaptation, retention and mucosa appearance) differed significantly between patients with titanium-base dentures and patients with resin-base dentures. Titanium bases are suitable for dentures likely to be subject to severe mechanical stresses (as in the case of maxillary complete dentures opposing natural teeth), and in patients who show hypersensitivity responses to other materials.
本研究的目的是比较钛基和树脂基上颌全口义齿。在13例佩戴钛基上颌全口义齿的患者（第一组）和12例佩戴树脂基上颌全口义齿的患者（第二组）中，评估了：(a)患者对义齿的适应情况，(b)义齿固位情况，以及(c)义齿下黏膜的外观。在所有病例中，通过问卷调查评估适应情况，而通过临床检查评估固位情况和黏膜外观。在钛基义齿患者和树脂基义齿患者之间，所考虑的三项指标（适应情况、固位情况和黏膜外观）均无显著差异。钛基适合可能承受严重机械应力的义齿（如与天然牙相对的上颌全口义齿的情况），以及对其他材料表现出过敏反应的患者。
