Abstract：
UNASSIGNED: To study the masticatory efficacy and oral health-related quality of life (OHRQoL) of participants wearing a mandibular overdenture retained by an immediate loading single implant with different occlusal tooth forms.
UNASSIGNED: For this nonrandomized controlled trial study, 27 edentulous participants were selected and randomly divided into three groups (n = 9) based on occlusal tooth forms of the mandibular implant overdenture (MIOD). Group I: participants received an MIOD with an anatomical tooth form; Group II: participants received an MIOD with a semianatomical tooth form; and Group III: participants received an MIOD with a nonanatomical tooth form. For each participant, a single implant (screw root form) was inserted into the midline of the mandibular ridge to support the MIOD. For each group, the masticatory efficiency was evaluated after 3 months, and the OHRQoL of the participants was evaluated after 3 and 6 months. One-way ANOVA and post hoc Tukey\'s test were used for data analysis (P < 0.05).
UNASSIGNED: The masticatory efficiency of the anatomic and semianatomic tooth forms was higher than that of the nonanatomic (P < 0.05). Moreover, the improvement in the participants\' OHRQoL in the anatomic group was more significant than that of other groups (P < 0.05).
UNASSIGNED: There was a greater improvement in masticatory efficiency and participants\' OHRQoL when fitted with an anatomic tooth form mandibular overdenture retained by an immediate loading single implant than with a semianatomic or nonanatomic tooth form.

摘要：
■研究佩戴下颌覆盖义齿的参与者的咀嚼功效和与口腔健康相关的生活质量（OHRQoL），该牙齿由具有不同咬合牙形式的即时负载单植入物保留。
■对于这项非随机对照试验研究，选择了27名无牙参与者，并根据下颌植入物覆盖义齿（MIOD）的咬合牙齿形式将其随机分为三组（n=9）。第一组：参与者接受了具有解剖牙齿形式的MIOD；第二组：参与者接受了具有半解剖牙齿形式的MIOD；第三组：参与者接受了具有非解剖牙齿形式的MIOD。对于每个参与者，将单个植入物（螺钉根形）插入下颌脊的中线以支持MIOD。对于每个小组，3个月后评估咀嚼效率，并在3个月和6个月后评估参与者的OHRQoL。数据分析采用单因素方差分析和事后Tukey检验(P<0.05)。
■解剖型和半解剖型牙齿的咀嚼效率高于非解剖型牙齿（P<0.05）。此外，解剖组参与者OHRQoL的改善比其他组更显著(P<0.05)。
■与半解剖或非解剖牙齿形式相比，当安装解剖牙齿形式的下颌覆盖义齿时，咀嚼效率和参与者OHRQoL的改善更大。
