Summary
Hybrid surface implants showed comparable crestal bone loss to moderately rough implants in patients needing bar-supported mandibular overdentures. This suggests hybrid implants are a viable option for edentulous mandibles.
Area of Science:
- Dental Implantology
- Biomaterials Science
Background:
- Mandibular overdentures provide a stable solution for edentulous patients.
- Implant surface characteristics influence osseointegration and bone maintenance.
Purpose of the Study:
- To compare crestal bone loss between hybrid and moderately rough implants in a split-mouth design.
- To evaluate implant performance in patients with bar-supported mandibular overdentures.
Main Methods:
- A split-mouth study involved 21 edentulous patients receiving one moderately rough and one hybrid implant each.
- Peri-apical radiographs assessed crestal bone levels at 3 and 12 months.
- Statistical analysis used the Wilcoxon signed-rank test for comparisons.
Main Results:
- No implant failures occurred in 42 implants after 1 year.
- Mean crestal bone loss was minimal and not statistically different between implant types or time points.
- Observed bone loss ranged from 0 to 3.93 mm over follow-up periods averaging 3.4 and 15.8 months.
Conclusions:
- Hybrid surface implants demonstrated comparable outcomes to moderately rough implants.
- Hybrid implants represent a potentially effective treatment option for the edentulous mandible.

01:16Clinical Trials
10.8K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

01:40Bone Remodeling
40.5K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

01:11Clinical Trials: Overview
5.0K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

01:31Osteoclasts in Bone Remodeling
4.2K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

11.2K
Nucleosomes are the basic units of chromatin compaction. Each nucleosome consists of the DNA bound tightly around a histone core, which makes the DNA inaccessible to DNA binding proteins such as DNA polymerase and RNA polymerase. Hence, the fundamental problem is to ensure access to DNA when appropriate, despite the compact and protective chromatin structure.
