Dental Implant Technology- Gendex GXCB-500 HD


Sample image of Gendex 500 HDSince acquiring our in-house Cone Beam Scanner, we have been able to help our patients by more accurately planning their dental implant treatment. Previously, we would have to refer the patient to a facility, such as a hospital, to take the scan. This was a burden for the patient, and usually caused them to delay important treatment that they wanted to complete. Moreover, hospital based scanners deliver doses of radiation that are higher than necessary for dental applications. Finally, patients have to deal with hospital staff and long waits.

Gendex CBCT ScanAt Pacific Northwest Specialists in Periodontics and Dental Implants, once the patient and doctor agree that a 3D scan is necessary, it only takes minutes to complete the scan and determine if the patient is a candidate for dental implants, has tooth or bone pathology, or has a wisdom tooth that may injure a nerve upon extraction. Even children benefit from this in-office technology; sometimes an extra tooth, called a supernumerary tooth, may prevent the eruption of the permanent tooth. Finding the exact location in three dimensions of the extra, unwanted tooth is critical to aid its removal. Exact location of the tooth means that the trauma of the removal procedure is reduced for the patient.

Patients sit while taking the scan and are in constant view of the technician or doctor operating the scanner. A scan can be completed in 20-30 seconds, so patients do not feel claustrophobic or tired. The data is then processed by specialized software so that the images can be seen and manipulated in three dimensions by the doctor. The results can be printed out or burned onto a CD so that patients may retain their results for their records or seek consultations with other dental and medical specialists.

Digital Radiography Technology

new technology xray headDigital radiography is a form of X-ray imaging, where digital X-ray sensors are used instead of traditional photographic film. Advantages include time efficiency through bypassing chemical processing and the ability to digitally transfer and enhance images. Also less radiation can be used to produce an image of similar contrast to conventional radiography.

Instead of X-ray film, digital radiography uses a digital image capture device. The gives advantages of immediate image preview and availability; elimination of costly film processing steps; a wider dynamic range, which makes it more forgiving for over- and under-exposure; as well as the ability to apply special image processing techniques that enhance overall display of the image.

The radiological examinations in dentistry may be classified into intraoral – where the film or sensor is placed in the mouth, the purpose being to focus on a small region of the oral-maxillofacial region and extra-oral where the film or sensor is placed outside the mouth aiming to visualize the entire oral maxillofacial region. Extra-oral imaging is further divided into orthopantomogram, showing a section, curved following more or less mandible shape, of the whole maxillofacial block and cephalometric analysis showing a projection, as parallel as possible, of the whole skull.

reitano technology dentalDigital radiography in dentistry provides the clinician with the ability to store their images on a computer. This provides two key advantages over film in the form of full screen images that can be enhanced and zoomed in on, aiding diagnostics and providing easier patient communication, as well as allowing dental offices to communicate images electronically, allowing for simpler referrals and, where applicable, easier insurance claim submission.

Here at Pacific Northwest Periodontics we use Indirect Imaging. Indirect digital imaging utilizes a reusable plate in place of the film. After X-ray exposure the plate (sheet) is placed in a special scanner where the latent formed image is retrieved point by point and digitized, using laser light scanning. The digitized images are stored and displayed on the computer screen. This method is halfway between old film-based technology and current direct digital imaging technology. It is similar to the film process because it involves the same image support handling but differs in that the chemical development process is replaced by scanning. This is not much faster than film processing and the resolution and sensitivity performances are contested. PSP has been described as having an advantage of fitting within any pre-existing equipment without modification because it replaces the existing film; however, it includes extra costs for the scanner and replacement of scratched plates.


Microscope Technology-Magnification

describe the image

Optical magnification has broadened the horizons of dentistry in general, and periodontology in particular. It has established microsurgical techniques for periodontal procedures by magnifying even minute anatomical structures, leading to enhanced mucogingival aesthetic outcomes by minimizing scarring and decreasing healing time.

A microscope is absolutely the best modality for consistent accurate visualization for dental procedures. Anything else is just a compromise. Microscopes are important in three main areas:


Microscopes provide multiple telescopic magnifications with a twist of a dial, from 3x to 20x. The higher magnification provided by microscopes allow for a wider field of view and a deeper depth of field than loupes.

Although loupes are available with magnification above 3x, there are drawbacks. Loupes have only a single magnification factor. Additionally, loupes with any factor above 3x have increasingly longer and heavier lenses, with a progressively smaller field of view. The additional weight makes holding one’s head steady a challenge, and the use of higher magnifications becomes difficult at best.


operatory dental technologyWhenever the degree of magnification is increased, the available light is spread out. For this reason anything under higher magnification appears darker. Additional light is required to compensate for this phenomenon. In order to achieve adequate illumination with loupes, one should purchase the optional headband light source which provides the spot illumination needed. Microscopes on the other-hand have an integrated, through the lens, bright fiber-optic light source. This light source completely eliminates shadows because it incorporates a coaxial (line of sight) light path that is always directed where you are looking. Some microscopes even have a built-in curing light filter that prevents light activated composites from polymerizing while using the scope for general dental procedures.


Microscopes really deliver on the promise of comfortable sit-down-dentistry. With a scope, it is no longer necessary to contort and bend your body to obtain good visualization. With proper microscope training, one can sit at the 12 o’clock position even while working with mandibular molars by learning to bring the patient to you, instead of you bringing yourself to the patient. Under a microscope, subtle patient head movements are all that is required for proper patient positioning to affect a more comfortable operating posture.


DentalVibe®-Experience Pain-Free Dental Injections!

Dentalvibe Pain Free InjectionsDentalVibe® is a revolutionary, patented, award-winning device invented by a dentist that uses vibration to block the sensation of pain. DentalVibe® is receiving recognition from dentists all around the world. These dentists are included in the dental specialties of pediatric dentistry, oral and maxillofacial surgery, endodontic, periodontics, orthodontics and general dentistry. Over 50% of Americans avoid dental care entirely due to the fear of pain! You no longer have to worry and stress-out about the fear of injection pain. Fear should no longer prevent patients from getting the care they desperately need and the treatments they truly desire.

DentalVibe uses unique, controlled VibraPulseTM technology to provide the most effective way to "close" the Pain Gate to the brain and block the discomfort of dental injections. Because your brain can adapt to a constant stimulus, negating a closure of the pain gate, DentalVibe® engineering and design team has equipped DentalVibe with the micro-processor controlled VibraPulse Technology.

The micro-sonic oscillations of DentalVibe's comfort tips are pulsed in a controlled pattern. Along with enhanced amplitude, VibraPulse Technology sends a soothing percussive or tapping stimulation deep into the oral mucosa, gently exciting the sub-mucosal sensory nerve endings. Brilliantly, it is this pulsed re-stimulation that maintains a closure of the gate, blocking the pain of an injection.
