What is a dental implant?A dental implant consists of a screw that is placed in the jawbone and a crown, which looks like a natural tooth and is anchored to the implant. When the screw is placed in the jawbone, it will in most cases integrate with the bone, which heals tightly around...
the concave side of the curvature is associated with increased Cobb angle correction•Higher implant density tends to overconstrain the instrumented spine and results in higher forces at bone-screw interface•If fewer screws are to be used, convex screw drop-out appears to be the most suitable...
These pictures show how to gain access to a loose second stage screw through a tooth crown cemented on a single dental implant. The crown was loose but the implant itself was solid. You need to differentiate this in advance. Use copious water irrigation with an air-water syringe in addition...
Digestive: The digestive system consists of a series of connected organs that together allow the body to break down and absorb nutrients from food and remove waste. It includes the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus. The large intestine is home to micro...
A prosthetic shoulder implant system includes a prosthetic humeral implant and a version device. The humeral implant includes a catch member aperture and a first locking pin aperture. The version device includes a rotatable member with a body and a flexure member, and a plate with a catch member...
Hydroxyapatite has a calcium to phosphorous ratio of approximately 1.67 which is generally the same as the calcium phosphate ratio in natural bone structures. These pastes may be placed in situ prior to setting in situations where bone has been broken, destroyed, degraded, become too brittle or ...

The objective was to computationally assess the biomechanical effects of implant ...
to craniofacial complex. In this respect, 3D reconstruction of the craniomaxillofacial region from CBCT is used in the diagnosis and planning of orthodontic treatment [5], maxillofacial surgery [6], oral implantology [7], often involving the transformation in a physical object (3D printing) for ...
