Performance and marginal bone level alteration around immediately loaded narrow-diameter implants. A prospective
Quintessence International (Berlin, Germany : 1985)
|February 28, 2018
Summary
Narrow-diameter implants (NDIs) demonstrated a high survival rate in edentulous mandibles. These implants provide a reliable solution for supporting prostheses in patients with limited bone volume.
Area of Science:
- Dental Implantology
- Prosthodontics
- Oral Surgery
Background:
- Edentulous mandibles often present with reduced horizontal bone volume, posing challenges for traditional dental implant placement.
- Narrow-diameter implants (NDIs) offer a potential solution for rehabilitating such patients.
Purpose of the Study:
- To evaluate the survival rate of four interforaminal immediately loaded narrow-diameter implants (NDIs) in the edentulous mandible.
- To assess radiologic crestal bone level alterations around these implants over a 52-week period.
Main Methods:
- A prospective clinical study involving 20 participants who received four 1.8 mm diameter NDIs each.
- Immediate loading was performed if insertion torque was ≥35 Ncm, with prostheses converted from existing dentures.
- Radiographic and clinical parameters were assessed at baseline and up to 52 weeks post-loading.
Main Results:
- All 80 implants showed uneventful healing, with no implant loss observed.
- 85% of implants were immediately loaded, demonstrating healthy peri-implant soft tissue conditions.
- Mean radiographic bone loss after 1 year was 0.78 mm (±0.64 mm).
Conclusions:
- Narrow-diameter implants (NDIs) appear to be a reliable option for supporting overdentures in edentulous mandibles.
- The findings suggest NDIs are a viable alternative for patients with reduced horizontal mandibular bone volume.

01:30Alterations in Respiration II
1.9K
There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...

01:27Margin of Error
7.7K
The margin of error is also called the maximum error of an estimate. The margin of error is the maximum possible or expected difference between the observed sample parameter value and the actual population parameter value. For proportion, it is the maximum difference between the value of sample proportion obtained from the data and the true value of population proportion. As the true value of the population parameter is not known, the margin of error is calculated using the sample statistic.

01:11Distribution of Stresses in a Narrow Rectangular Beam
549
In studying beam stress distribution, examining an elemental section is essential. To determine the average shearing stress on this face, the calculated shear is divided by the surface area. Importantly, shearing stresses on the beam's transverse and horizontal planes mirror each other, indicating a consistent stress distribution along the upper region of the beam. Notably, shearing stresses are absent at the beam's upper and lower surfaces due to the absence of applied forces in these...

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...

Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.

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...
