As a dental practice that understands the struggle of missing one or more teeth, Bellevue Family Dentistry offers a permanent solution through dental implants in Bellevue. We know that gaps in the teeth may affect the way a person eats, smiles, and interacts with people. Dental implants can help resolve these concerns, as they work to restore both the look and function of an individual’s set of pearly whites.

Dental implants in Bellevue have taken giant leaps in the past 30 years. Today, the success rate of dental implant procedures has risen to 80%, making it one of the most popular and effective methods for replacing lost teeth.

INDICATIONS

Your Bellevue dentist may recommend an implant when:

-You are missing a tooth, and you don’t want a bridge. With a bridge, the teeth adjacent to the space require crowns or abutments to which your dentist will attach the replacement tooth. With Bellevue dental implants, the adjacent teeth are left untouched.

-Your dentures do not fit properly and are uncomfortable. A mini-dental implant (MDI) may help keep loose dentures in place. Compared with a conventional implant, an MDI is thinner in diameter, allowing it to fit into a smaller location. Mini implants work well for securing loose dentures, especially those in the lower arch area.

CONTRAINDICATIONS

  • Smoking: A debatable contraindication, but it is believed that since smoking inhibits blood flow to tissues, this may inhibit healing and prevent full osseointegration.
  • Uncontrolled diabetes: With Type II diabetes, if uncontrolled, impairs implant healing due to the body’s poor blood flow and circulation.
  • Bruxism: Also known as tooth grinding or clenching, this parafunctional habit also delays healing. Dental implants do not have a periodontal ligament like their natural tooth counterparts to cushion occlusal forces. Heavy grinding may cause little movements within the implant, increasing likelihood of failure. Your dentist may decide to have you wear a nightguard to help alleviate this trauma.
  • Oral bisphosphonate (ie. Fosamax and Boniva): A highly debatable topic, it is thought that bisphosphonates, especially IV induced, cause osetonecrosis (death of bone). The American Dental Association has various articles and studies on this controversial phenomenon.
  • Anatomy: For implants on the lower jaw, particular attention needs to be placed on the location of the mental foramen (MF) and inferior alevolar nerve (IAN); for the upper jaw, the maxillary sinus level. If the MF and IAN are disturbed during surgery, it may cause nerve damage via prolonged numbness (parathesia) or painful numbness(dysesthesia).
  • If the maxillary sinus is invaded, prolonged sinus issues may result. Your dentist or surgeon may elect to do a sinus lift prior the implant surgery. With upper teeth, especially the roots of the molars and premolars, they may be in very close relation to the maxillary sinus. Because sometimes this sinus level is low, an implant may actually pierce the sinus space. With a sinus lift, the maxilla’s sinus floor is “lifted” or pushed higher up and then filled with extra bone. This procedure allows the implant to osseointegrate within the extra bone substance, and also prevents the sinus from being invaded.

WHAT IS A DENTAL IMPLANT

implant dentist in BellevueImplants are composed of a surgical grade titanium that is biocompatible with the jaw bone. The exterior surfaces of the implant may be modified by adding plasma or etched to increase surface area and to enhance and promote osseointegration.

Unlike natural teeth implants do not have a periodontal ligament, hence the feeling may be different from natural teeth.

A dental implant is essentially a screw that is surgically placed in either jaw and serves as an anchor for a new post and crown. Most implants placed today are a “root-form” which means it serves as a replacement of the root. Because of the high success rate of dental implants, they are generally a good replacement option of a natural tooth.

PROCEDURE

An implant procedure has 4 general stages:

  1. The dental surgeon or general dentist surgically places the implant in the jaw bone with a precision drill, and is typically aided with a surgical stent. A panoramic x-ray and/or a CT ( cone beam computed tomography ) scan is typically done to evaluate bone density and location of adjacent nerve and blood vessels. If necessary, the surgeon may place a tissue and/or bone graft to ensure there is sufficient bone to hold the implant in place. If an implant is placed near the front where the smile line is critical, the surgeon will determine if a tissue graft is necessary to make sure there is enough gingival tissue. A collar, or healing cap, is then placed over the head of the implant to ensure the gum tissue to heal properly.
  2. dental implants BellevueAfter the implant is placed, there is a typical wait time of 3-6 months to allow the implant to heal and for it to osseointegrate with the jaw bone. The titanium is fully bio-compatible, permitting bone to grow around and onto the implant.
  3. When the surgeon has deemed the implant fully osseointegrated, the collar or healing cap is removed, an impression is taken and sent to the dental lab to fabricate an abutment and crown. An abutment is a “fence post” that is screwed within the implant itself. A shade is also taken to help match the final implant crown to the adjacent teeth. If the crown is located in a critical esthetic zone (ie. anterior smile zone) you may need go to the dental lab to have a custom shade for a more precise shade match.
  4. The final crown is then attached onto the abutment via screw or cement. Your dentist can recommend whether a screw retained or cement retained is appropriate for your implant.
