摘　　要：目的研究青年正常者前伸颌位和侧颌位的接触情况。方法 2010年9月至2011年4月按纳入标准,从福建医科大学1350名本科生中筛选162名正常志愿者,男55名,女107名,年龄18～23岁。用Bausch咬合膜拉出法检测前伸及侧颌位的接触牙位,分别归纳、统计两种颌位的接触情况分布。结果前伸颌位:前牙接触、后牙无接触者111人(68.52%),前、后牙均有接触者49人(30.25%),后牙接触、前牙无接触者2人(1.23%)。侧颌位:工作侧接触、非工作侧无接触241人(74.38%),工作侧、非工作侧均有接触75例(23.15%),非工作侧接触、工作侧无接触8人(2.47%),其中双侧一致者142人(87.65%),双侧不一致者20人(12.35%)。结论在正常人群,前伸颌位时,可能出现仅有前牙接触和前、后牙均有接触及仅有后牙接触的接触情况,其中仅有前牙接触的接触情况最常见;侧颌位时,可能出现仅有工作侧接触和工作侧、非工作侧均有接触及仅有非工作侧接触的接触情况,其中仅有工作侧接触最常见。在侧颌位,大部分人为双侧一致。Objective To study the situation of occlusion contact in the normal occlusions at mandibular protrusion and lateral excursion. Methods Totally 162 volunteers were recruited from Fujian Medical University（male55,female107,age：18-23） . Occlusions of the volunteers were examined with thin articulating film at protrusion and lateral excursion. Results At protrusion,111 volunteers had contacts only on their anterior teeth（68.52%） ,49 had contacts both on anterior and posterior teeth（30.25%） ,and 2 volunteers had contacts only on posterior teeth（1.23%） . In lateral excursion,the majority of volunteers had contacts only at the working side（241 cases,74.38%）;many people contacted both at the working and non-working sides（75 cases,23.15%）;a few volunteers only had contacts at the non-working side（8 cases,2.47%） .Among the volunteers,142 of them were bilateral symmetry（87.65%） ,and 20 were bilateral asymmetry（12.35%） . Conclusion Within the limitation of the study,in mandibular protrusion,contacts only at anterior teeth are most frequently to be observed,while at mandibular lateral excursion,contacts only at the working-side are the predominance. The majority is bilateral symmetry.
