[Clinical retrospective study of navigation guided impacted maxillary supernumerary tooth extraction]
1Department of Oral and Maxillofacial Trauma and Plastic Aesthetic Surgery, School of Stomatology, Wuhan University, Wuhan 430079, China.
Summary
Navigation-guided extraction of impacted supernumerary teeth is efficient, reducing operative time. However, it requires more preoperative planning time for the navigation system design.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Navigation Technology
Background:
- Supernumerary teeth can cause impaction and complications.
- Surgical extraction is often necessary.
- Minimally invasive techniques are sought for improved outcomes.
Purpose of the Study:
- To evaluate the efficiency and safety of navigation-guided extraction for impacted supernumerary teeth.
- To compare navigation-guided versus conventional extraction methods.
Main Methods:
- A comparative study involving 50 patients (25 navigation-guided, 25 conventional).
- Analysis of preoperative planning time, system installation time, and operative time.
- Inclusion of cases with single and multiple impacted supernumerary teeth.
Main Results:
- Navigation system design averaged 45.0±8.0 minutes; installation averaged 15.0±2.8 minutes.
- Average operative time was significantly shorter in the navigation group (0.64±0.08 hours) compared to the control group (0.91±0.09 hours).
Conclusions:
- Navigation-guided extraction reduces overall surgical operation time for impacted supernumerary teeth.
- Increased preoperative planning time is a trade-off for enhanced intraoperative efficiency.

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

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...

614
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

01:20Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
354
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

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...
