How do braces straighten crooked teeth?


Braces use constant, gentle pressure, which over time, move teeth into their proper positions. Your braces are at work every moment of your orthodontic treatment. The two main components of your braces are: the brackets that are placed on your teeth and the main archwire that connects them. The bracket is a piece of shaped metal or ceramic that we affix to each tooth. The archwire is bent to reflect your "ideal" bite. In other words, it reflects the way we want you to look after treatment.
The wire threads through the brackets and, as the wire tries to return to its original shape, it applies pressure to move your teeth. Picture your tooth resting in your jaw bone. With pressure on one side from the archwire, the bone on the other side gives way. The tooth moves. New bone grows in behind.

Attached to your braces, elastics (rubber bands) exert the proper force that creates the right amount of pressure to move teeth. In order for this force to remain constant, elastics must be worn all the time and changed every day.

Dental Implants


Dental implants are changing the way people live. They are designed to provide a foundation for replacement teeth that look, feel, and function like natural teeth. The person who has lost teeth regains the ability to eat virtually anything, knowing that teeth appear natural and that facial contours will be preserved. Patients with dental implants can smile with confidence.

What Are Dental Implants?

The implants themselves are tiny titanium posts that are surgically placed into the jawbone where teeth are missing. These metal anchors act as tooth root substitutes. The bone bonds with the titanium, creating a strong foundation for artificial teeth. Small posts that protrude through the gums are then attached to the implant. These posts provide stable anchors for artificial replacement teeth.
Implants also help preserve facial structure, preventing bone deterioration that occurs when teeth are missing.

The Surgical Procedure

For most patients, the placement of dental implants involves two surgical procedures. First, implants are placed within your jawbone. For the first three to six months following surgery, the implants are beneath the surface of the gums gradually bonding with the jawbone. You should be able to wear temporary dentures and eat a soft diet during this time. At the same time, your dentist is forming new replacement teeth.
After the implant has bonded to the jawbone, the second phase begins. Your doctor will uncover the implants and attach small posts that protrude through the gums and will act as anchors for the artificial teeth. When the artificial teeth are placed, these posts will not be seen. The entire procedure usually takes six to eight months. Most patients experience minimal disruption in their daily life.

Surgical Advances

Using the most recent advances in dental implant technology, your doctor is able to place single stage implants. These implants do not require a second procedure to uncover them, but do require a minimum of six weeks of healing time before artificial teeth are placed. There are even situations where the implants can be placed at the same time as a tooth extraction – further minimizing the number of surgical procedures. Advances in dental implant technology have made it possible, in select cases, to extract teeth and place implants with crowns at one visit. This procedure, called “immediate loading”, actually performs the implant placement?
Implants are a team effort between an oral and maxillofacial surgeon and a restorative dentist. While your doctor performs the actual implant surgery, initial tooth extractions, and bone grafting if necessary, the restorative dentist (your dentist) fits and makes the permanent prosthesis. Your dentist will also make any temporary prosthesis needed during the implant process.

What Types Of Prosthesis Are Available?

A single prosthesis (crown) is used to replace one missing tooth – each prosthetic tooth attaches to its own implant. A partial prosthesis (fixed bridge) can replace two or more teeth and may require only two or three implants. A complete dental prosthesis (fixed bridge) replaces all the teeth in your upper or lower jaw. The number of implants varies depending upon which type of complete prosthesis (removable or fixed) is recommended. A removable prosthesis (over denture) attaches to a bar or ball in socket attachments, whereas a fixed prosthesis is permanent and removable only by the dentist.
Your doctor performs in-office implant surgery in a hospital-style operating suite, thus optimizing the level of sterility. Inpatient hospital implant surgery is for patients who have special medical or anesthetic needs or for those who need extensive bone grafting from the jaw, hip or tibia.

Why Dental Implants?

Once you learn about dental implants, you finally realize there is a way to improve you life. When you lose several teeth – whether it’s a new situation or something you have lived with for years – chances are you have never become fully accustomed to losing such a vital part of yourself.
Dental implants can be your doorway to renewed self-confidence and peace of mind.
A Swedish scientist and orthopedic surgeon, Dr. Per-Ingvar Branemark, developed this concept for oral rehabilitation more than 35 years ago.  With his pioneering research, Dr. Branemark opened the door to a lifetime of renewed comfort and self-confidence for millions of individuals facing the frustration and embarrassment of tooth loss.

Why Select Dental Implants Over More Traditional Types Of Restorations?

There are several reasons: Why sacrifice the structure of surrounding good teeth to bridge a space? In addition, removing a denture or a “partial” at night may be inconvenient, not to mention that dentures that slip can be uncomfortable and rather embarrassing.

Are You A Candidate For Implants?

If you are considering implants, your mouth must be examined thoroughly and your medical and dental history reviewed. If you mouth is not ideal for implants, ways of improving outcome, such as bone grafting, may be recommended.

What Type Of Anesthesia Is Used?

The majority of dental implants and bone graft can be performed in the office under local anesthesia, with or without general anesthesia.

Do Implants Need Special Care?

Once the implants are in place, they will serve you well for many years if you take care of them and keep your mouth healthy. This means taking the time for good oral hygiene (brushing and flossing) and keeping regular appointments with your dental specialists.

Teeth-In-An-Hour™

TEETH-IN-AN-HOUR™ is a revolutionary concept providing patients with fully functioning teeth on dental implants in one single procedure that lasts about an hour. This technology was recently developed by Nobel Biocare and allows for collaboration between both the restorative doctor and the surgeon. This merging of knowledge and experience achieves not only increased safety, but also a more precise implant placement. In addition, the fabrication of a final prosthesis is completed prior to the surgery. The computer-guided implant surgery is done in an arthroscopic fashion without requiring any flap reflection. This benefits the patient in that there is less postoperative discomfort, less swelling and less bruising. Patients can often resume their normal activities the next day.
The process starts when a CAT scan is taken of the patient's jawbone. This CAT scan allows for the generation of a three-dimensional model of the jawbone that can then be used in virtual reality software to plan the implant placement without the presence of the patient. The results are more accurate implant placement, and less chair time for the patient at the surgery office.

Facial Trauma


Facial Trauma

The dental specialist performs the proper treatment of facial injuries. These professionals must be well versed in emergency care, acute treatment and long-term reconstruction and rehabilitation – not just for physical reasons but emotional as well. Oral and maxillofacial surgeons are trained, skilled and uniquely qualified to manage and treat facial trauma. Injuries to the face, by their very nature, impart a high degree of emotional, as well as physical trauma to patients. The science and art of treating these injuries requires special training involving a “hands on” experience and an understanding of how the treatment provided will influence the patient’s long term function and appearance.
Your doctor meets and exceeds these modern standards. They are trained, skilled, and uniquely qualified to manage and treat facial trauma. They are on staff at local hospitals and deliver emergency room coverage for facial injuries, which include the following conditions:
  • Facial lacerations
  • Intra oral lacerations
  • Avulsed (knocked out) teeth
  • Fractured facial bones (cheek, nose or eye socket)
  • Fractured jaws (upper and lower jaw)

The Nature Of Maxillofacial Trauma

There are a number of possible causes of facial trauma such as motor vehicle accidents, accidental falls, sports injuries, interpersonal violence, and work-related injuries. Types of facial injuries can range from injuries of teeth to extremely severe injuries of the skin and bones of the face. Typically, facial injuries are classified as either soft tissue injuries (skin and gums), bone injuries (fractures), or injuries to special regions (such as the eyes, facial nerves or the salivary glands).

Soft Tissue Injuries Of The Maxillofacial Region

When soft tissue injuries such as lacerations occur on the face, they are repaired by suturing. In addition to the obvious concern of providing a repair that yields the best cosmetic result possible, care is taken to inspect for and treat injuries to structures such as facial nerves, salivary glands, and salivary ducts (or outflow channels). Your doctor is a well-trained oral and maxillofacial surgeon and is proficient at diagnosing and treating all types of facial lacerations.

Bone Injuries Of The Maxillofacial Region

Fractures of the bones of the face are treated in a manner similar to the fractures in other parts of the body. The specific form of treatment is determined by various factors, which include the location of the fracture, the severity of the fracture, the age, and general health of the patient. When an arm or a leg is fractured, a cast is often applied to stabilize the bone to allow for proper healing. Since a cast cannot be placed on the face, other means have been developed to stabilize facial fractures.
One of these options involves wiring the jaws together for certain fractures of the upper and/or lower jaw. Certain other types of fractures of the jaw are best treated and stabilized by the surgical placement of small plates and screws at the involved site. This technique of treatment can often allow for healing and obviates the necessity of having the jaws wired together. This technique is called "rigid fixation" of a fracture. The relatively recent development and use of rigid fixation has profoundly improved the recovery period for many patients, allowing them to return to normal function more quickly.
The treatment of facial fractures should be accomplished in a thorough and predictable manner. More importantly, the patient's facial appearance should be minimally affected. An attempt at accessing the facial bones through the fewest incisions necessary is always made. At the same time, the incisions that become necessary, are designed to be small and, whenever possible, are placed so that the resultant scar is hidden.

Injuries To The Teeth & Surrounding Dental Structures

Isolated injuries to teeth are quite common and may require the expertise of various dental specialists. Oral surgeons usually are involved in treating fractures in the supporting bone or in replanting teeth that have been displaced or knocked out. These types of injuries are treated by one of a number of forms of splinting (stabilizing by wiring or bonding teeth together). If a tooth is knocked out, it should be placed in salt water or milk. The sooner the tooth is re-inserted into the dental socket, the better chance it will survive. Therefore, the patient should see a dentist or oral surgeon as soon as possible. Never attempt to wipe the tooth off, since remnants of the ligament that hold the tooth in the jaw are attached and are vital to the success of replanting the tooth. Other dental specialists may be called upon such as endodontists, who may be asked to perform root canal therapy, and/or restorative dentists who may need to repair or rebuild fractured teeth. In the event that injured teeth cannot be saved or repaired, dental implants are often now utilized as replacements for missing teeth.
The proper treatment of facial injuries is now the realm of specialists who are well versed in emergency care, acute treatment, long-term reconstruction, and rehabilitation of the patient.
