Summary
Custom subperiosteal dental implants offer a solution for severe jaw bone loss. Utilizing accessible 3D imaging and printing technologies, this method reduces costs and treatment time for patients.
Area of Science:
- Biomaterials and Biomedical Engineering
- Dental Implantology
- Medical Device Manufacturing
Background:
- Standard screw-type dental implants are insufficient for patients with extreme jaw bone resorption.
- Custom subperiosteal implants present an alternative to complex procedures like sinus lifts or nerve lateralization.
- Traditional subperiosteal implants have a long history of use in challenging cases.
Purpose of the Study:
- To establish and test a streamlined workflow for designing and producing custom subperiosteal dental implants.
- To demonstrate the feasibility of using freely available software and 3D printing for custom implant fabrication.
- To make advanced dental implant solutions more accessible and affordable.
Main Methods:
- Processing patient computed tomography (CT) data to create a 3D virtual model.
- Utilizing accessible design software (Autodesk Inc.) for error correction and implant modeling.
- Employing direct metal laser sintering (DMLS) 3D printing with Ti64 titanium alloy for fabrication.
Main Results:
- Successfully converted patient CT data into a watertight STL model of the maxilla.
- Designed and produced a custom subperiosteal implant using affordable software and 3D printing.
- Demonstrated a cost-effective method for producing custom medical devices.
Conclusions:
- A cost-effective workflow for custom subperiosteal dental implants is achievable using accessible software and 3D printing.
- This approach enhances the availability of advanced dental treatments for patients with significant bone loss.
- Reduces reliance on expensive specialized software, benefiting smaller clinics and production facilities.

172
Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...

Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as the...

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

01:09Clearance Models: Physiological Models
297
Drug clearance is a critical pharmacokinetic process involving the irreversible removal of drugs from the body through various organs over a specified time period. Physiological models are indispensable in determining organ-specific clearance, defined by the proportion of the drug eliminated per unit of time from the organ's blood volume.
The organ's clearance rate depends on the blood flow to the organ and the extraction ratio (E). The extraction ratio describes the organ's...

01:25Clearance Models: Compartment Models
302
Clearance measures drug elimination from the central compartment, including plasma and highly perfused organs like kidneys and liver. Its calculation varies depending on pharmacokinetic models and administration routes. The one-compartment model, for instance, portrays the pharmacokinetics of polar drugs such as aminoglycoside antibiotics administered intravenously and readily excreted in urine. In this case, clearance is influenced by the terminal rate constant (λz) and the total volume...
