Implant Placement Technique

The implant itself is made from titanium. Titanium has a very high affinity to bone. After a careful medical and dental history is taken and evaluated. Proper models, x-rays and other diagnostic tools are reviewed and the decision to use an implant has been made - the actual placement occurs. At the time of the implant placement (an office procedure) easily and carefully, an opening is made in the bone that corresponds exactly to the length and diameter of the implant body. The implant is seated, the tissue repositioned and sutured into place. Most people who undergo this surgery say that the discomfort is minimal post operative.

Now the implant actually "osseous integrates" (biologically fuses) to the bone. This process of integration takes usually from 4 to 6 months. During this time, the implant remains covered over and no forces are placed on it. Dentures may be worn during this healing time. After the integration has been allowed to occur, in a very simple procedure, an extension is placed onto the implant so that an impression can be made.

From the precise impression and lab procedures, the crown (cap) is created. Finally the finished crown is cemented or screwed into place on the implant.

Implants

Dr. Hafernik now performs the actual implant surgery here in our office. After careful study of your overall health, required x-rays and other evaluations, we can schedule you for this procedure. No longer is there any reason for seeing a dental specialist and, as can sometimes be the case, this can lower expense for you as well.

Implants are a great alternative for replacing a missing tooth, missing teeth or help anchor dentures securely. Implantology has been in dentistry for decades and has become over that time predictable and successful. There are now hundreds of thousands of implants placed each year world wide with tremendous long-term success.

Implant longevity

Just like your real teeth, implants require very careful cleaning each and every day. Regular dental hygiene appointments are just as important (if not more so). It is true that implants can't decay, but they are susceptible to periodontal problems just like real teeth. Other very important factors are the correct placement of your implant in secure bone and a very correct bite to minimize stresses - these decisions are made by the doctor directing your care.

There are implants that have been successfully used for over 30 years. Now, with a better understanding of fundamentals and studies performed, we expect implants to be 95%+ successful for 30 years and most likely a lifetime

Implants are a very exciting part of today's dentistry. If there is an opportunity for us to share any information or provide a FREE consultation for possible implant placement, please do not hesitate to call.

Bonding

Another method of handling the esthetic problems noted above in the porcelain veneer topic is bonding. This technique involves placing a composite resin directly onto the enamel of the teeth to be added to or covered. Composite resin has the appearance and consistency of dough until it is exposed to a special light source. Although bonding can look as good as veneers... they will generally not last as long.

Tooth Colored Crowns (Caps)

Porcelain applied over a dark metal casting for many decades has been the only choice for crowns that appear tooth colored (cosmetic). There were (and are) problems with this type of crown. First, perfect enamel color can be very difficult to achieve due to the dark metal under the porcelain and at times a grey edge at the gum margin. Although there are alternatives for less dark metal, the problems still exist to a certain extent. Second, porcelain is a glass - plain and simple - and glass can break. It is fairly common to see porcelain to metal crowns on molars (back teeth) chip or break completely free of the metal substructure. For many years there has been increasing patient demands for improved esthetics in dental restorations. This demand has been especially strong in the area of front teeth that require crowns (caps). There have been MANY attempts over the past few decades or more to provide "all ceramic/porcelain" crowns. In other words, a crown that would not have a metal substructure under it. The reasons for wanting to eliminate the metal are primarily to get rid of the dark line at the very edge of the crown and to let more light pass through (to look more lifelike). Generally speaking, all these materials have failed to live up to expectations. Fracturing was the primary problem. Time passes and materials and techniques improve. There now exists NEW all ceramic (not a porcelain) materials that have revolutionized the creation of enamel colored crowns.

2 of these NEW materials are - 

Lithium Disilicate

Exhibiting superior durability (multiple times stronger than tradiitional porcelain) and the most color robust ceramic system to date. The opalescence, translucency and light diffusion properties of lithium disilicate were all designed to replicate natural tooth structure for beauty and undetectable restorations. Although both front teeth and back molars can be made, these are best suited for the front teeth where chewing pressures are the least.

Zirconia

Virtually unbreakable and biocompatible. Over 10 times more strength than traditional porcelain, resistant to chipping, cracking or breaking in the mouth makes zirconia crowns ideal for bruxers and grinders, who have broken their natural teeth or porcelain restorations in the past. Zirconia crowns are a combination of zirconium (a tooth colored metal) and its oxide (a white powder ceramic). Dentists have long relied on full-cast gold for long-term durability and strength. But with the introduction of all zirconia restorations an equally strong tooth colored solution is now available. What's more, when compared side-by-side to full-cast gold and porcelain metal crowns, zirconia crowns are the most natural-looking choice. Zirconia works very well on the back molars where strength is required.

But there have been improvements in metal based porcelain crowns as well.

  • Using gold metals instead of darker metals for a "warmth" of color.
  • Better (much better) porcelains for better colors.
  • Better preparing of teeth so that there is sufficient porcelain for natural light to come through.
  • No metal exposed at any areas that can be seen ...what is referred to as "porcelain margins".
