3D Imaging in Dentistry

Dental x-rays are a routine part of your dental visit. Unfortunately, x-rays can only show the healthcare provider a 2D image of your tooth structure and supporting bone. Our North Stapley office is excited to now offer our patients a 3D imaging device called Cone Beam Computed Tomography, or CBCT. All patients at any of our locations can utilize this great technology.  This device is able to capture a 3D scan of a patient’s maxillofacial skeleton for diagnostic purposes.

Uses for a CBCT Scan:

CBCT scans are used in many different fields of dentistry to improve diagnosis and treatment planning in the following cases:

Endodontics
-Tooth morphology, number of canals and root curvature
-Identification of periapical pathology
-Location of trauma, root fractures

Dental implants
– Location of anatomic structures
– Size and shape of ridge, quantity and quality of bone
-Number, orientation of implants
-Need for bone graft, sinus lift
– Use of implant positioning software

Oral and maxillofacial surgery
– Relationship of third molar roots to mandibular canal
– Localization of impacted teeth, foreign objects
-Evaluation of facial fractures
-Location and characterization of lesions

Orthodontics
– Treatment planning for complex cases
– Impacted teeth
-Root angulation, root resorption

Sleep Apnea
-Identification of obstructive airway

Temporomandibular joint or TMJ
– Osseous structures of TMJ
-Relationship of condyle and fossa

How Does It Work:

The patient is precisely placed in a comfortable position at the machine. The scan takes about 20 seconds to rotate around the head, obtaining nearly 600 distinct images. The focused x-ray beam reduces scatter radiation, resulting in better image quality. Once complete, the 3D image is immediately available for viewing and diagnosing. The scan produces a wide variety of views and angles that can be manipulated to provide a more comprehensive evaluation. One CBCT scan uses about 1/20th the radiation of a traditional head and neck scan at the hospital.

There are many benefits to using a 3D imaging CBCT system in dentistry. We are excited to be able to provide top of the line technology to our patients. This new machine will be beneficial in increasing predictability by decreasing failure to provide you with the best quality of care!

What is a Dental Implant?

KO6A3300-Edit[1]

Amanda Orvis RDH

A dental implant is a titanium post used to replace missing teeth and support dental prosthetics. Implants are surgically guided into the jaw bone and integrate with the bone to support a dental prosthesis such as a crown, bridge and/or denture.

Success or failure of dental implants can depend on a few factors. Smoking is one of the number one causes of implant failure. Smoking can slow down the healing as well as act as an irritant to the tissue and bone surrounding the implant. Certain prescription medications can affect the integration of the implant with the surrounding bone as well. Stress to the implant due to clenching and/or grinding, also known as bruxing, can also be a significant factor on the success or failure of the implants. All of these potential issues will be discussed during your implant evaluation appointment.

Individual tooth replacement

For an individual tooth, an implant is selected and placed into the site of the missing tooth. The implant is given 3-6 months time to heal and integrate into the surrounding bone so that it becomes permanently stable. Once the implant has integrated with the surrounding bone the implant is ready to be restored. An impression is taken to allow a custom crown to be fabricated. Once the crown is fabricated, an implant abutment is placed into the implant and secured by a screw. The crown is then cemented in place on top of the implant abutment.

Implant supported bridge

An implant supported bridge is a group of teeth supported by two or more dental implants. The process of placing an implant supported bridge is very similar to the individual implant placement discussed above. To begin, implants are selected and placed into the sites of two or more missing teeth. The implants are given time to heal and to integrate with the surrounding bone. Once the implants have integrated with the surrounding bone the implants are ready to be restored. An impression is taken to allow a custom bridge to be fabricated. Implant abutments are placed into the implants and then secured with screws. The implant abutments will act as anchors to support the floating teeth between the implants known as pontics. The bridge is then cemented in place on top of the implant abutments.

Implant Supported Denture

Implant supported dentures can be made to be removable or permanently fixed into the mouth. Removable implant supported dentures can be disconnected from the implant abutments with finger pressure by the wearer. To enable this, the abutment is shaped as a small connector, which can be connected to an adapter on the underside of the denture. A permanently fixed implant supported denture is secured in place by your dentist with screws. Even though dentures are placed, it is still import to note that you must visit with your dentist at least once a year to have your tissue and implants examined.

Mini Implants Stablize Loose Fitting Dentures

 

Nothing is more frustrating for a dental patient, than a loose fitting denture.  If there was a conservative option to secure your dentures in a day, would that be of interest to you?

Mini implants are a wonderful option to secure your existing denture.  Yes, we can use your existing denture.  Mini implants are smaller in diameter than regular implants.  They do not require surgery or healing time prior to being able to place the denture on the implants.  Usually, a minimum of four implants are placed in the bone.  They denture is modified by the dentist to house specialize attachments.  These attachments tightly fasten the denture to the mini implants.  Patients report little discomfort and a lot of satisfaction with their smile and functionality.

One appointment is all it takes to have a firmly secure denture, in one day!
