Author: Brian Krans. Jan 19, · A stent is a tiny tube that a doctor places in an artery or duct to help keep it open and restore the flow of bodily fluids in the area. Stents help .
A dental surgical stent is an how to install window plastic device made from a model of the patient's mouth that fits over the area where dental implants are to be placed and helps guide the oral surgeon in correct placement of implants.
The stent contains holes that are pre-drilled. The dental surgical stent is placed over existing teeth, bone or gums.
Impressions are made of the patient's mouth and from those impressions molds are created. These molds are then used to create the surgical stent from acrylic.
X-rays or CT scans are also used to create the stent. Some stents are made with acrylic and metal or ceramic tubes to guide drilling. When the stent is use, the surgeon can drill through the holes in the stent; the stent helps guide the placement and angle of the drilling. Stents can be restrictive or non-restrictive. Restrictive stents allow the surgeon to hwat precisely where the stent guides and therefore place the implants in an exact position.
Non-restrictive dtent give the surgeon what is a medical stent used for leeway in mfdical implant placement. A drawback of non-restrictive stents is that the implant can be placed in a position that was not uused planned by the restorative dentist. Radiographs can also be taken with the stent in place to verify placement before drilling.

Coronary stents are now used in nearly all angioplasty procedures. A stent is a tiny, expandable metal mesh coil. It is put into the newly opened area of the artery to help keep the artery from narrowing or closing again. Once the stent has been placed, tissue will start to coat the stent like a layer of skin. Dec 09, · Stents still a good choice for unstable angina Since their introduction in the s, stents have been widely used in the treatment of CAD. Stents are effective at relieving angina in patients who continue to experience symptoms despite being on appropriate medicines. stent. (stent) [Charles Thomas Stent, Brit. dentist, –] 1. Originally, a compound used in making dental molds. 2. Any material or device used to hold tissue in place, to maintain open blood vessels, or to provide a support for a graft or anastomosis while healing is taking place.

It restores blood flow to the heart muscle without open-heart surgery. Angioplasty can be done in an emergency setting such as a heart attack. Or it can be done as elective surgery if your healthcare provider strongly suspects you have heart disease. Angioplasty is also called percutaneous coronary intervention PCI. For angioplasty, a long, thin tube catheter is put into a blood vessel and guided to the blocked coronary artery.
The catheter has a tiny balloon at its tip. Once the catheter is in place, the balloon is inflated at the narrowed area of the heart artery. This presses the plaque or blood clot against the sides of the artery, making more room for blood flow. The healthcare provider uses fluoroscopy during the surgery. This is called coronary angiography. The healthcare provider may decide that you need another type of procedure.
This may include removing the plaque atherectomy at the site of the narrowing of the artery. In atherectomy, the provider may use a catheter with a a rotating tip.
When the catheter reaches the narrowed spot in the artery, the plaque is broken up or cut away to open the artery. Coronary stents are now used in nearly all angioplasty procedures.
A stent is a tiny, expandable metal mesh coil. It is put into the newly opened area of the artery to help keep the artery from narrowing or closing again. Once the stent has been placed, tissue will start to coat the stent like a layer of skin. The stent will be fully lined with tissue within 3 to 12 months, depending on if the stent has a medicine coating or not.
You may be prescribed medicines called antiplatelets to decrease the "stickiness" of platelets. Platelets are special blood cells that clump together to stop bleeding. The medicine can also prevent blood clots from forming inside the stent. Your healthcare team will give specific instructions on which medicines need to be taken and for how long. Most stents are coated with medicine to prevent scar tissue from forming inside the stent.
These stents are called drug-eluting stents DES. They release medicine within the blood vessel that slows the overgrowth of tissue within the stent. This helps prevent the blood vessel from becoming narrow again. Some stents don't have this medicine coating and are called bare metal stents BMS.
They may have higher rates of stenosis, but they don't require long-term use of antiplatelet medicines. This may be the preferred stent in people who are at high risk of bleeding. Because stents can become blocked, it's important to talk with your healthcare team about what you need to do if you have chest pain after a stent placement.
If scar tissue does form inside the stent, you may need a repeat procedure. This may be using either balloon angioplasty or with a second stent. In some cases, radiation therapy may be given through a catheter placed near the scar tissue to stop the growth of scar tissue and open up the vessel.
This is called brachytherapy. Angioplasty is done to restore coronary artery blood flow when the narrowed artery is in a place that can be reached in this manner. Not all coronary artery disease CAD can be treated with angioplasty. Your doctor will decide the best way to treat your CAD based on your circumstances. Rupture of the coronary artery or complete closing of the coronary artery, needing open-heart surgery.
You may want to ask your healthcare team about the amount of radiation used during the procedure and the risks related to your particular situation. It's a good idea to keep a record of your radiation exposure, such as previous scans and other types of X-rays, so that you can tell your healthcare team.
Risks linked to radiation exposure may be related to the total number of X-rays or treatments over a long period. For some people, having to lie still on the procedure table for the length of the procedure may cause some discomfort or pain. There may be other risks depending on your specific health condition. Discuss any concerns with your healthcare team before the procedure. You will be asked to sign a consent form that gives your permission to do the procedure.
Read the form carefully and ask questions if anything is unclear. Tell your healthcare team if you have ever had a reaction to any contrast dye, or if you are allergic to iodine. Tell your healthcare team if you are sensitive to or are allergic to any medicines, latex, tape, and local or general anesthesia. Tell your healthcare team if you are pregnant or think you could be. Radiation exposure during pregnancy may lead to birth defects. Tell your healthcare team of all prescription and over-the-counter medicines, vitamins, herbs, and supplements that you are taking.
Tell your healthcare team if you have a history of bleeding disorders or if you are taking any blood-thinning medicines anticoagulant or antiplatelet , aspirin, or other medicines that affect blood clotting.
You may need to stop some of these medicines before the procedure. But for planned angioplasty procedures, your doctor may want you to continue taking aspirin and antiplatelet medicines, so be sure to ask.
Your provider may request a blood test before the procedure to find out how long it takes your blood to clot. Other blood tests may be done as well. Angioplasty may be done as part of your stay in a hospital. Procedures may vary depending on your condition and your doctor's practices.
Most people who have angioplasty and stent placement are monitored overnight in the hospital. You will be asked to remove any jewelry or other objects that may interfere with the procedure.
You may wear your dentures or hearing aid if you use either of these. If there is a lot of hair at the area of the catheter insertion often the groin area , the hair may be shaved off.
An IV intravenous line will be started in your hand or arm before the procedure. It will be used for injection of medicine and to give IV fluids, if needed. You will be connected to an electrocardiogram ECG monitor that records the electrical activity of your heart and monitors your heart rate using electrodes that stick to your skin.
Your vital signs heart rate, blood pressure, breathing rate, and oxygen level will be monitored during the procedure. There will be several monitor screens in the room, showing your vital signs, the images of the catheter being moved through your body into your heart, and the structures of your heart as the dye is injected. You will get a sedative in your IV to help you relax. However, you will likely stay awake during the procedure.
Your pulses below the catheter insertion site will be checked and marked so that the circulation to the limb below the site can easily be checked during and after the procedure. Local anesthesia will be injected into the skin at the insertion site.
This may be in your leg, arm, or wrist. You may feel some stinging at the site for a few seconds after the local anesthetic is injected. Once the local anesthesia has taken effect, a sheath, or introducer, will be put into the blood vessel often at the groin.
This is a plastic tube through which the catheter will be threaded into the blood vessel and advanced into the heart. The catheter will be threaded through the sheath into the blood vessel.
The doctor will advance the catheter through the aorta into the heart. Fluoroscopy will be used to help see the catheter advance into the heart.
The catheter will be threaded into the coronary arteries. Once the catheter is in place, contrast dye will be injected through the catheter into your coronary arteries in order to see the narrowed area s. You may feel some effects when the contrast dye is injected into the IV line.
These effects include a flushing sensation, a salty or metallic taste in the mouth, or a brief headache. These effects usually last only a few moments. Tell your doctor if you feel any breathing trouble, sweating, numbness, itching, nausea or vomiting, chills, or heart palpitations.
After the contrast dye is injected, a series of rapid X-ray images of the heart and coronary arteries will be taken. You may be asked to take in a deep breath and hold it for a few seconds during this time. When the doctor locates the narrowed artery, the catheter will be advanced to that location and the balloon will be inflated to open the artery. You may have some chest pain or discomfort at this point because the blood flow is temporarily blocked by the inflated balloon.
Any chest discomfort or pain should go away when the balloon is deflated. However, if you notice any continued discomfort or pain, such as chest pain, neck or jaw pain, back pain, arm pain, shortness of breath, or breathing trouble, tell your doctor right away. The doctor may inflate and deflate the balloon several times. The decision may be made at this point to put in a stent to keep the artery open.
In some cases, the stent may be put into the artery before the balloon is inflated. Then the inflation of the balloon will open the artery and fully expand the stent.
