Summary
Computerized tomography (CT)-guided surgery accurately places dental implants. This study found high accuracy in both the maxilla and mandible, with minimal deviations, ensuring straight implant placement.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Medical Imaging
Background:
- Fully edentulous maxilla and mandible present challenges for dental implant placement.
- Computerized tomography (CT)-guided surgery offers a potential solution for precise implant positioning.
Purpose of the Study:
- To evaluate the linear and angular deviations of dental implants placed using CT-guided surgery.
- To compare implant accuracy between the maxilla and mandible.
Main Methods:
- 18 patients with fully edentulous arches received 115 implants via CT-guided surgery.
- Virtual planning based on tomographic examination and prosthesis.
- Postoperative tomography used to measure deviations between planned and actual implant positions.
Main Results:
- No significant differences in linear or angular deviations between maxillary and mandibular implants.
- A trend towards greater linear deviations in apical vs. coronal regions and posterior vs. anterior regions observed.
- CT-guided surgery demonstrated high accuracy, enabling straight implant pillar placement.
Conclusions:
- CT-guided surgery is a highly accurate technique for dental implant placement in fully edentulous patients.
- The technique ensures precise implant positioning, minimizing deviations and facilitating prosthetic rehabilitation.

If the rotational definitions are compared with the definitions of linear kinematic variables from motion along a straight line and motion in two and three dimensions, we can observe a mapping of the linear variables to the rotational ones.
When comparing the linear and rotational variables individually, the linear variable of position has physical units of meters, whereas the angular position variable has dimensionless units of radians, as it is the ratio of two lengths. The linear velocity...

Polarography is a classical voltammetric technique used to analyze electrochemical reactions. This method applies a linear potential sweep to a dropping mercury electrode (DME), and the resulting current is measured. A dropping mercury electrode is commonly used as the working electrode in polarography. It consists of a capillary tube filled with mercury, where the tiny droplet forms at the tip. This droplet continuously drops from the capillary, creating a new electrode surface for each...

In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

01:10Standard Deviation
27.6K
The most commonly used measure of variation is the standard deviation. It is a numerical value measuring how far data values are from their mean. The standard deviation value is small when the data are concentrated close to the mean, exhibiting slight variation or spread. The standard deviation value is never negative, it is either positive or zero. The standard deviation is larger when the data values are more spread out from the mean, which means the data values are exhibiting more variation.

The mean absolute deviation is also a measure of the variability of data in a sample. It is the absolute value of the average difference between the data values and the mean.
Let us consider a dataset containing the number of unsold cupcakes in five shops: 10, 15, 8, 7, and 10. Initially, calculate the sample mean. Then calculate the deviation, or the difference, between each data value and the mean. Next, the absolute values of these deviations are added and divided by the sample size to...
