Summary
Ultra-wide diameter implants (>6 mm) placed in molar extraction sockets show predictable clinical outcomes with minimal bone loss. These implants demonstrate comparable papilla and crown dimensions to natural teeth, ensuring high patient satisfaction.
Area of Science:
- Dental Implantology
- Oral Surgery
- Prosthodontics
Background:
- Limited data exists on the clinical outcomes of ultra-wide diameter implants (>6 mm).
- This study focuses on ultra-wide diameter implants placed in molar extraction sockets.
Purpose of the Study:
- To evaluate the clinical outcomes of ultra-wide diameter implants placed immediately after molar extraction.
- To assess bone loss, soft tissue dimensions, and patient satisfaction associated with these implants.
Main Methods:
- Ultra-wide diameter implants (7-9 mm) were placed in molar extraction sockets using a 1-stage, flapless protocol without bone grafts.
- Implants were loaded after 4 months with single screw-retained crowns.
- Bone loss, plaque, bleeding, and dimensions (crown, papilla) were evaluated and compared to contralateral natural teeth.
Main Results:
- A mean follow-up of 23 months showed minimal bone loss (mean 1.16 mm apical to implant-abutment junction).
- No significant differences were observed in papilla height, crown length, or zenith compared to natural teeth.
- Patient satisfaction was high (72.5% reported no problems), with less plaque accumulation around implants than teeth.
Conclusions:
- Ultra-wide diameter implants demonstrate predictable clinical outcomes with minimal bone loss in molar extraction sockets.
- Restorations with these implants achieved dimensions comparable to contralateral natural teeth.
- The findings support the use of ultra-wide diameter implants for molar replacement.

01:54Molar Mass
86.9K
The identity of a substance is defined not only by the types of atoms or ions it contains but by the quantity of each type of atom or ion. For example, water, H2O, and hydrogen peroxide, H2O2, are alike in that their respective molecules are composed of hydrogen and oxygen atoms. However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the water molecule, which has only one, the two substances exhibit very different properties.

15.7K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

03:43Applications of the Ideal Gas Law: Molar Mass, Density, and Volume
63.5K
The volume occupied by one mole of a substance is its molar volume. The ideal gas law, PV = nRT, suggests that the volume of a given quantity of gas and the number of moles in a given volume of gas vary with changes in pressure and temperature. At standard temperature and pressure, or STP (273.15 K and 1 atm), one mole of an ideal gas (regardless of its identity) has a volume of about 22.4 L — this is referred to as the standard molar volume.

01:30Continuous Renal Replacement Therapy
1.1K
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

01:17Design Example: Calculating Safe Diameter for Wind-Exposed Disc
359
Assessing safety in wind-exposed installations is crucial to preventing potential failures. This example explores the calculation and design adjustments needed to mount a circular disc on a building facade, where wind forces are a primary concern. A 4-meter diameter disc was initially designed as an aesthetic feature facing winds at a velocity of 25 meters per second, with an air density of 1.25 kilograms per cubic meter. Given these conditions, the drag force on the disc was determined using...

222
Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in...
