Complete Denture Base Group: 1.Complete dentition loss for more than 3 months. According to the classification of the absorption degree of edentulous alveolar ridges, those with absorption degree at grade 1 - 2 are selected for inclusion. 2.Symmetrical face and normal mouth opening. 3.Without severe systemic diseases or psychological diseases, with good compliance, willing to accept the requirements of clinical trials and having given informed consent.

排除标准:

树脂嵌体组: 1.尚未完全控制的牙龈炎、牙周炎患者; 2.不能正确刷牙,不能保持良好口腔卫生的患者; 3.咬合力过大,或有咬合不良习惯如磨牙症,紧咬牙等。 全口义齿基托组: 1. 急慢性颞下颌关节紊乱; 2. 口、颌面化学治疗史; 3. 黏膜慢性炎症、增生等或其他将试验过程复杂化的口腔病理状态; 4. 其他影响全口义齿修复治疗的健康状况。

Exclusion criteria:

Resin Inlay Group: 1.Patients with gingivitis or periodontitis that is not yet fully controlled; 2.Patients who are unable to brush their teeth properly and cannot maintain good oral hygiene; 3.Patients with excessive occlusal force or bad occlusal habits such as bruxism and clenching.
