科学领域:
- 数字牙科数字牙科
- 生物医学工程 生物医学工程
- 牙科技术 牙科技术
背景情况:
- 口腔内扫描仪 (IOS) 在数字牙科中至关重要,但它们的准确性可能会受到临床因素的影响,例如空间限制和患者运动.
- 在口腔内扫描期间的机动性受到狭窄空间的限制,这可能会影响数据采集和扫描器性能.
研究的目的:
- 调查机动性约束对口内扫描仪的准确性准确性和效率的影响.
- 为了比较受限条件下的口内扫描性能与开放的口外扫描.
主要方法:
- 15名初学者参与者使用Aoralscan 3 IOS.扫描了大和下类型牙模型.
- 扫描是在两个条件下进行的:在玩偶上进行受约束的口内扫描和开放的口外扫描.
- 通过RMS偏差,植入物间距离和植入物角度偏差来评估真实性准确性. 扫描时间测量效率.
主要成果:
- 在口内扫描和口外扫描之间没有发现真实性准确度 (RMS偏差,植入物间距离,植入物角度偏差) 的显著差异.
- 外口扫描显著减少了两个模型的扫描时间 (p < 0.0001).
- 未经验的操作人员在口内限制下显示了更长的扫描时间,表明效率降低.
结论:
- 单独的机动性限制可能不会显著影响口内扫描仪的真实性准确性,而不是与长椅扫描相比.

01:26Constraints and Statical Determinacy
1.0K
In structural engineering, the equilibrium of a system is not only determined by its equations of equilibrium but also with the help of constraints. Constraints refer to restrictions on the motion of a system. The proper combinations of constraints can minimize the total number of constraints needed to maintain a system in mechanical equilibrium. When this happens, the system is said to be statically determinate. For such systems, the unknown reaction supports can be estimated using equilibrium...

01:19Impact of Groups on Groups
262
Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...

Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...

01:28Impact of Groups on Individuals
375
Groups play a fundamental role in shaping individual behavior, as they establish norms that guide interactions and decision-making. Social psychology examines how individuals conform to group expectations, often adjusting their attitudes and actions to align with group norms. These norms can be formal, such as workplace policies, or informal, such as unspoken social expectations within a fraternity.Conformity and Social InfluenceConformity arises when individuals modify their behaviors or...

In social psychology, the interplay between individuals and groups is a central concern, particularly regarding how individual actions and characteristics influence group processes and outcomes. While much research emphasizes the group's power in shaping individual behavior, it is equally significant to understand how individuals contribute to the functioning, development, and success of groups.Individual Roles in Group Productivity and Decision-MakingIndividuals are not passive participants in...

01:30Impact of Schemas
223
Schemas are cognitive structures that provide a framework for interpreting and organizing social information. They help individuals navigate complex environments by offering expectations about people, events, and behaviors. Schemas influence attention, encoding, and retrieval processes, thereby shaping the entire trajectory of information processing in social contexts.Attention and Cognitive LoadDuring initial attention, schemas function as filters that prioritize schema-consistent information,...
