While there’s usually a period of months between implant placement and the permanent crown, a new technique known as same-day tooth replacement installs both the implant and a temporary crown during the same visit. But be advised — it does have its risks and isn’t for everyone.
Successful same-day replacements require special attention during the three phases for implants: the removal (extraction) of the existing tooth; placement of the implant in the bone; and attachment of the crown, the visible tooth, to the implant. The tooth extraction lays the foundation for the entire process; the extraction procedure must be performed carefully to avoid undue damage to the socket. In addition, if infection or disease has compromised the site, an implant may not be possible immediately.
The implant must then be placed in the bone so that it’s stable and immovable. All implants stabilize with time as the bone grows and adheres to them, but we need greater stability for a same-day tooth replacement when an extraction is performed.
Our last consideration is positioning the implant so that the attached crown blends in naturally with the surrounding gum tissue and adjacent teeth. We must place it at the proper depth below the gum tissues so that the crown appears to emerge from them in the proper tooth length.
Taking extra care during all these phases, including the angle of crown attachment, will increase our chances of success. We still run a risk of implant damage or failure, however, from biting forces before the implant fully integrates with the bone. This means avoiding chewy foods and other situations that might increase the force on the implant. We may also use a temporary crown that’s slightly shorter than adjacent teeth so it won’t make full contact with the opposing tooth.
If you’d like to know if you’re a good candidate for a same-day tooth replacement, see us for a detailed examination. After reviewing your needs, we’ll be able to discuss with you the risks and benefits for a new look in one day.

For a predictable outcome, a dental implant should be placed as soon as the bone and gum tissues following a tooth extraction have healed. But what happens if the tooth has been missing for months or years? You might then run the risk of not having enough bone to properly place an implant.
This can happen because of a disruption in the growth cycle of living bone tissue. As older bone cells dissolve (resorption), new bone develops to take its place. This is a dynamic process, as the amount and exact location of the new growth is in response to changes in the mouth, particularly from forces generated by the teeth as we chew. If, however, this stimulation transmitted to the bone no longer occurs because the tooth is missing, the bone will tend to dissolve over time.
In fact, within the first year after a tooth loss the associated bone can lose as much as a quarter of its normal width. This is why we typically place bone grafting material in an empty socket at the same time as we extract the tooth. This encourages bone growth during the healing period in anticipation of installing a dental implant or a fixed bridge. If, however, the bone has diminished to less than required for a dental implant, we must then use techniques to encourage new bone growth to support a future implant.
One such technique for restoring bone in the back of the upper jaw is to surgically access the area through the maxillary sinus (a membrane-lined air space within the bone structure of the face) positioned just over the jawbone to place grafting material. During surgery performed usually with local anesthesia, the surgeon accesses the sinus cavity, lifts the tissue membrane up from the sinus floor and applies the grafting material on top of the bone. Eventually, the new bone growth will replace the grafting material.
If successful, the new bone growth will be sufficient to support an implant. Thanks to this renewed growth, you’ll soon be able to enjoy better function and a transformed smile provided by your new implant.

Dental implants are considered the premier option for tooth replacement. While all implant procedures follow the same general concept — a titanium post surgically inserted into the jawbone with an attached life-like crown — the installation process can vary.
From their earliest history, implants have usually been installed through a two-stage process. In the first stage, the surgeon inserts the titanium post in the bone and leaves it “submerged” below the gum level to protect it from oral bacteria and the effects of chewing and biting. About three months later after the bone attaches to the titanium (a process called osseointegration), the surgeon then performs the second stage by re-exposing the implant and attaching a temporary abutment and crown for the patient to wear while the permanent abutment and crown are fabricated and later attached in 2-6 weeks.
In recent years, advancements in materials and design have made possible a one-stage process that allows the implant to protrude above the gum line during osseointegration and shortens the process. After the initial three-month healing period, the implant is ready for “loading” with the permanent crown.
The choice between which of these two procedures should be used for your implants will first depend on the type of tooth being replaced. A front tooth benefits from the one-stage procedure for cosmetic reasons because the surgeon can install a temporary crown to the exposed abutment during osseointegration (as long as the temporary tooth isn’t in functional contact with other teeth). An implant for a back tooth, on the other hand, doesn't have a large cosmetic demand so those one stage procedures usually end up with an exposed healing abutment but no temporary crown.
The strength of the bone is also a factor. Some bone tends to be softer, particularly in the back of the mouth. There’s a chance the implant could move in this softer bone, adversely affecting the outcome. For this reason, the two-stage procedure can be the preferred approach for posterior teeth as it offers more protection from movement.
You can be sure we’ll consider all these and other factors during your initial examination, and then advise you on the best approach. Above all, we want to make sure — whether a one-stage or a two-stage implant process — the result is a smile you can be proud of.

Perhaps you’ve heard a lot about dental implants, an increasingly popular tooth replacement system. Although they can be expensive (depending on the exact application) they have a number of important benefits that add value to your investment.
Here are four of those benefits that make dental implants one of the best tooth replacement options available:
Life-like Appearance. Like an automobile, an implant’s “engine” — the titanium post inserted into the jawbone — is covered by a stylish “body” — the visible crown, custom-made to look just like the natural tooth. Composed of porcelain ceramic or a similar translucent material, the implant crown is the key to not only restoring natural function in the mouth but also rejuvenating your smile.
Long-term Durability. Implants have been in use for over three decades (over 3 million placed since their introduction) and have built an impressive track record for durability. If properly cared for, it’s possible for dental implants to last for many years or even a lifetime. Compared with other restorations that may not last as long and lead to additional dental cost, the implant’s “return on investment” can be quite high.
Contribution to Bone Health. Most implants are made of surgical titanium, which has a strong affinity with bone. In time, bone cells will grow and fuse with the titanium. The result is not only a solid anchoring of the implant into the jaw, but also the preservation and possible re-growth of bone mass where it may have been lost.
Versatility. Although implants are often used as a single tooth replacement, they’re increasingly used in multiple-tooth replacements. A few strategically placed implants can permanently support a bridge (two or more teeth linked together), an arch (an entire set of upper or lower teeth), or as a foundational support for a removable denture, particularly the lower arch.
If you’ve experienced tooth loss, a preliminary dental examination will determine if you’re a potential candidate for dental implant replacement. If so, dental implants could be a way for you to not only restore lost function but also regain your smile.

Although your teeth feel as if they’re rigidly set in the jawbone, they’re actually capable of movement. In fact, dynamic tooth movement is an essential mechanism in good dental function — it allows your teeth to adapt to changes brought on by age and other factors.
The periodontal ligament is a key component in this mechanism. This elastic tissue actually holds the teeth to the bone through tiny fibers that attach to the tooth root on one side of the ligament and to the jawbone on the other. The teeth move within the ligament to maintain contact with both adjacent and opposing teeth in response to changes like the normal wear that occurs due to aging.
This is a primary reason why a missing tooth should be replaced by an artificial one as soon as possible. Because of the tendency just described, teeth next to the space left by the missing tooth will begin to move (or drift) into the space at an accelerated rate. The end result is teeth out of their normal position and range, which could seriously disrupt their normal function as well as adversely affect your appearance.
This is especially important for back teeth. Because they’re not easily visible to others when we open our mouths, many people will forgo replacement when they’re lost. But missing back teeth can set off a chain reaction of movement that could eventually hinder jaw function.
The best option for a tooth replacement is a dental implant. Life-like and durable, dental implants encourage bone growth at the implant site and adjacent teeth will respond to it as they would a natural tooth. If an implant isn’t feasible, then a fixed bridge is also a viable replacement option that will prevent drift. As a result, tooth movement should continue normally with no adverse effects on function.
If you’ve lost teeth or are about to undergo tooth extraction, it’s in your other teeth’s best interest to consider a permanent replacement. A new implant or bridge will vastly improve your smile and prevent more serious problems in the future.
