Evaluation of the split bone technique for lateral ridge augmentation: A retrospective case-control study.
Summary
The split bone technique shows a 100% implant survival rate and low complications for bone augmentation. However, smoking and gender can negatively impact bone resorption around implants.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Bone Grafting Techniques
Background:
- Bone augmentation is crucial for dental implant success.
- The split bone technique offers a method for obtaining autogenous bone.
- Evaluating its efficacy and complications is essential for clinical practice.
Purpose of the Study:
- To assess early complications, implant survival, and bone resorption with the split bone technique.
- To analyze patient-related factors (gender, smoking) and implant system effects on bone resorption.
Main Methods:
- Retrospective case-control study of patients undergoing split bone grafting.
- Comparison with a control group receiving implants without augmentation.
- Radiographic measurement of vertical bone resorption and Kaplan-Meier survival analysis.
Main Results:
- 100% implant survival in the split bone group vs. 98.5% in the control group.
- Median vertical bone resorption was 0.7 mm (study) vs. 0.6 mm (control) after 5 years.
- Smokers showed significantly more bone resorption (2.8 mm) than non-smokers (0.6 mm).
Conclusions:
- The split bone technique is a reliable method with a low complication rate and excellent implant survival.
- This technique does not increase peri-implant bone resorption.
- Smoking and gender are identified as potential risk factors for increased bone resorption.

01:27Cranial Bones: Lateral View
4.4K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

417
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

01:13¹H NMR: Complex Splitting
1.8K
A proton M that is coupled to a proton X results in doublet signals for M. However, NMR-active nuclei can be simultaneously coupled to more than one nonequivalent nucleus. When M is coupled to a second proton A, such as in styrene oxide, each peak in the doublet is split into another doublet.
Splitting diagrams or splitting tree diagrams are routinely used to depict such complex couplings. While drawing splitting diagrams, the splitting with the larger coupling constant is usually applied...

01:28Lateralization
993
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

01:13¹H NMR Signal Multiplicity: Splitting Patterns
6.5K
When protons A and X are coupled, their nuclear spin energy levels are slightly modified. This is because the energy required to excite proton A to a spin state parallel to proton X is slightly different from the energy required for it to become anti-parallel to spin X. Consequently, there are two possible excitation frequencies for A (A1 and A2), depending on the spin state of X, and vice versa. The mutual nature of coupling implies that the difference between frequencies A1 and A2, indicated...

01:10Interpreting ¹H NMR Signal Splitting: The (n + 1) Rule
2.5K
In the AX proton spin system, proton A can sense the two spin states of a coupled proton X, resulting in a doublet NMR signal with two peaks of equal (1:1) intensity. When proton A is coupled to two equivalent protons (AX2 spin system), the spin states of each X can be aligned with or against the external field, creating three possible scenarios. This results in a 1:2:1 triplet signal, where the central peak corresponds to the chemical shift of A and is twice as large or intense as the...
