Dental Implant: Causes of Failure

Dental implants are designed to be a permanent replacement for a missing tooth or teeth and are also growing to be popular alternative to removable dentures or fixed bridges.

Still some patients do experience some complications. The following are a few of the possible causes and reasons behind dental implant failure:

Success Rates

The majority of the problems that occur after the implant placement are generally minor and easily resolved. If something goes wrong, consult your dentist or surgeon.

Osseo-Integration

Osseo-integration is the formation of functional and structural bond between bone and an artificial implant. This process takes place over several months after the implant is placed in the bone.

The failure of the jawbone to fuse together properly with the implant is considered to be a failed osseo-integration. An implant is failed if it is mobile, falls out of bone or shows signs of bone loss of more than 1 mm even after the first year.

For patients who don’t have adequate bone height, width or length, procedures such as a sinus lift or bone graft can help in increasing space and bone mass loss.

Peri-Implantitis (Infection)

Peri-implantitis, or infection, is a condition that involves inflammation of the gum and/or bone around the implant. A form of periodontal disease, peri-implantitis can cause bone loss and implant failure.

 

Nerve & Tissue Damage

When an implant is placed too close to a nerve, patients may experience chronic pain, tingling or numbness in their cheek, gums, tongue, lips or chin.

Some bleeding and pain is to be considered normal for a couple days after the surgery, but if the pain is extreme, the bleeding excessive or they it last longer than a few days, one should contact their dentist as soon as possible

Overloading

Immediate loading is a all-in-one stage treatment method where the crown and abutment are placed on the dental implant right after the implant placement.

The normal process consists of a two stages and provides time for the implant to integrate with the bone before adding the external components.

Overloading refer to failures caused by excessive pressure or forces placed on the protruding abutment and/or crown. These forces easily disrupt the osseo-integration process.

Sinus Problems

An oral surgeon may perform a sinus augmentation procedure, to develop a strong bone foundation. The goal is to create more bone in that area in order to support a dental implant.

Sometimes if the implant protrudes into the sinus cavity, that area can become infected and/or inflamed. Patients should always inform their oral surgeon about sinus related issues prior to the implant procedure.

Other Risks & Causes Of Failure

The following are other risks and causes are:

  • Foreign body rejection–it is possible that a patient’s body will reject the dental implant.
  • Failure of the implant itself–An implant can crack or fracture if it is subjected to excessive external force impact like a blow to the face or excessive pressure over a period of time like grinding teeth or an unbalanced crown.
  • Allergic reaction–While it is quite rare, some patients can have an allergic or inflammatory reaction to titanium.

Contraindications

  • Bruxism (tooth grinding or clenching)
  • Failure to locate a primary nerve in the lower jaw
  • Uncontrolled Type II diabetes
  • Insufficient bone height, width or length
  • Oral or intravenous bisphosphonates
  • Smoking

 

SMILES FOR TWO: TIPS TO MAINTAIN GOOD ORAL HEALTH FOR YOU AND YOUR BABY

                                                    By. Dr.Rajat Sachdeva

INTRODUCTION

Pregnancy is a unique period during a women’s life and is characterized by complex physiological changes, which may adversely affect oral health. Research indicates that the health of your mouth mirrors the condition of your whole body; when your mouth is healthy, chances of your overall health are good too. At the same time, various dental treatments like preventive, diagnostic and restorative are safe during pregnancy and also helps in improving and maintaining good oral health.

Evidence suggests that most infants and young children acquire caries- causing bacteria from their mothers. Providing education and counseling to pregnant woman to promote oral health behaviors may reduce the transmission of such bacteria from mothers to infants and young children, thereby preventing onset of caries.

ORAL HEALTH AND PREGNANCY: If you are pregnant or considering becoming pregnant, keep your oral health in mind.

Pregnancy causes hormonal changes that may put you at increase risk of developing gum disease which, in turn, can affect the health of your developing baby. Recent research suggests a link between gum disease and pre-term, low-birth-weight babies. Regardless, practicing preventive dental care during pregnancy has been proven to protect oral and overall health, and is safe for mothers and children.

PREGNANCY-RELATED ORAL CONDITIONS

Pregnancy hormones cause changes throughout the body – even in your mouth.  It’s important for you to take good care of your teeth and gums while pregnant.

Below are some tips to help you to maintain good oral health before, during and after pregnancy.

BEFORE YOU GET PREGNANT 

If your last dental visit took place more than 6 months ago or if any oral health problems were identified, try to get dental appointment before you get pregnant. In that way, careful assessment of your teeth and gum tissue (gingiva) can be done. And any oral health problem can be treated before you get pregnant.

DURING PREGNANCY

Dental care is safe and essential during pregnancy. Tell the dental office that you are pregnant and your due date. This information will help the dental team provide the best care for you. Schedule a dental exam in your first trimester. Scaling and root planning to control periodontal disease can be undertaken safely; avoid using metronidazole in first year.

As a precautionary measure, dental treatments during the first trimester and second half of the third trimester should be avoided as much as possible, except in the case of an emergency. However, routine dental care can be received during the second trimester. All elective dental procedures should be postponed until after the delivery.

Avoid dental X-rays during pregnancy. If X-rays are essential (such as in a dental emergency), your dentist will use extreme caution to safeguard you and your baby. Advances in technology have made X-rays much safer today than in past decades.

Regular periodontal (gum) exams are very important, because pregnancy causes hormonal changes that put you at increased risk for periodontal disease characterized by red, swollen and tender gums that are more likely to bleed. Women who already have gingivitis may find that their symptoms become more severe. Pay particular attention to any changes in your gums during pregnancy.

NUTRITION AND ORAL HEALTH: Choose healthy, balanced diet that may include fruits, vegetables, protein, whole grains like cereals, bread, or crackers; and dairy products like cheese, milk, or unsweetened yogurt. Drink plenty of water or milk instead of juice. Try to avoid between-meal snacks; if you do snack, opt for nutritious, low sugar foods like raw fruits and fresh vegetables. Avoid sugary snacks. Sweet cravings are common during pregnancy. However, keep in mind that the more frequently you snack, the greater the chance of developing tooth decay. Your baby’s teeth begin to develop between the third and sixth month of pregnancy. Eat a healthy diet that includes calcium, protein, phosphorus and vitamins A, C and D to give your baby’s smile a healthy start.

MAINTAIN GOOD ORAL HYGIENE: Brush your teeth with fluoridated toothpaste twice a day. Clean between the teeth with floss or interdental cleaner at least once a day to keep your mouth healthy. Rinse your mouth out with water or a mouth rinse if you suffer from morning sickness and have bouts of frequent vomiting. After meal, chew xylitol-containing gum or mints etc, this can help to reduce bacteria that can cause tooth decay.

AFTER THE PREGNANCY

If you experienced any gum problems during your pregnancy, see your dentist soon after delivery to have your entire mouth examined and periodontal health evaluated.

We look forward to helping you upgrade your smile and your quality of life!
