Implant Dentistry

Losing a tooth due to injury, dental decay, or gum disease can happen. However, in order to avoid causing problems for the adjacent teeth and your overall dental health, it is important to replace the tooth that has been lost. This can be done a number of ways including fixed bridges, removable partial or full dentures as well as a more recent procedure known as dental implants.

One of the most significant dental innovations in recent times, an implant is a small surgical fixture made of biocompatible metal or ceramic materials that is placed into the jawbone and functions in the same manner as the root of a tooth. In the same way that natural root supports the natural crown of your tooth, an implant once it fully integrates with the surrounding bone, provides a stable and durable foundation for a replacement tooth. Implants often support a crown for an individual tooth, but can also be used as abutment teeth for a dental bridge, or strategically placed to help stabilize a denture.

Out of all of the restorative choices available today an implant comes the closest to replicating the look, feel and function of a natural tooth. Furthermore, it is the only method of tooth replacement that does not require the involvement or preparation of the adjacent teeth. A dental implant also stimulates bone remodeling to prevent shrinkage in areas where teeth are missing and helps to restore facial contours in areas where significant bone loss has occurred.

Dental Bone Graft

In order for a dental implant to be stable and secure, it must be completely covered with bone circumferentially. Unfortunately, sometimes a patient may present with inadequate bone. In a bone graft procedure, the surgeon will take a section of bone from another area of your body, or - as is most often the case now - use a special bone grafting material, and graft it onto your jaw bone. Some graft materials used by the dentist may be human, cow or synthetic bone. After the bone graft is completed the patient needs to wait approximately 6-10 months. If the bone graft needed is minimal, then it is possible to have the implant placement and the bone graft done at the same time. The dentist performing the surgery will make the final decision at the time of the surgery. A successful bone graft surgery will create enough bone in height, width and density so that a dental implant can be held firmly.

Unfortunately, the outcome of the procedure is largely dependent on the patients post op compliance. Therefore, the dentist should spend some time with the patient reviewing the post op instructions thoroughly and the patient should follow these instructions diligently.

As with any surgical procedure, it is important to discuss your personal medical history and all the risks and benefits of the surgery with your dental specialist.

Sinus Lift

A key to implant success is the quantity and quality of the bone where the implant is to be placed. The upper back jaw has traditionally been one of the most difficult areas to successfully place dental implants due to insufficient bone quantity and quality and the close proximity to the sinus. If you've lost bone in that area due to reasons such as periodontal disease or tooth loss, you may be left without enough bone height to place implants.

Sinus lift surgery can help correct this problem by raising the sinus floor and placing bone graft material in order to create more height. Depending on your individual needs, the bone usually will be allowed to develop for about four to 12 months before implants can be placed. After the implants are placed, an additional healing period is required. In some cases, the implant can be placed at the same time the sinus is augmented.

Undergoing sinus lift surgery has been shown to greatly increase your chances for successful implants that can last for years to come.

Moderate Intravenous Sedation
moderate intravenous sedation

Moderate Moderate Intravenous Sedation involves a sedative that is administered intravenously, or directly into a vein. It is indicated when deeper sedation is required due to dental phobia or anxiety which makes it perfect for people with apprehension about any dental work needed. This type of sedation can be quickly modified to your state of consciousness and can be continued as long as necessary for the procedure.

The Benefits of Moderate Intravenous Sedation Dentistry

Some of the benefits of Moderate Intravenous Sedation dentistry include:

  • Offers a Higher Level of Sedation – When compared to oral sedation or inhalation sedation, Moderate Intravenous Sedation offers a higher level of sedation.
  • Works Quickly – Since medications are administered intravenously, the medications begin to take effect quickly. Oral sedatives can take an hour or more to act.
  • Quick Recovery Times – Patients generally have a shorter recovery time with Moderate Intravenous Sedation than they do with oral sedation or general anesthesia.
  • Works for Severe Anxiety – Even patients dealing with severe anxiety can benefit from Moderate Intravenous Sedation, since it achieves a high level of sedation.
  • Amnesia – Amnesia is a common side effect of the medications used for Moderate Intravenous Sedation, so patients rarely remember the dental procedure.
  • Diminishes the Gag Reflex – For patients with a sensitive gag reflex, the Moderate Intravenous Sedation can help to suppress that reflex, making dental treatment easier.
  • Patients are Still Conscious – Patients stay conscious during this type of sedation, making it a great alternative to general anesthesia for patients who want to avoid the risk of complications that come with general anesthesia, the high costs, or for those who may not be healthy enough to undergo general anesthesia.

Sedation Instructions

Determining if you are a candidate for Moderate Intravenous Sedation will require a consultation. Dr Yoo will review your medical & dental history, examine your dental needs, and prescribe treatment as needed. If you are to receive treatment under Moderate Intravenous Sedation, it is very important that

  • You may not have anything to eat or drink (including water) for eight (8) hours prior to the sedation appointment.
  • A responsible adult must accompany the patient to the office, remain in the office during the procedure, and then drive the patient home after the procedure.
  • No smoking for at least 12 hours before the Moderate Intravenous Sedation appointment.
  • The patient should not drive or operate heavy machinery for 24 hours following the sedation appointment.
  • The patient should not be left unattended after the Moderate Intravenous Sedation procedure. An adult must remain with the patient.
  • Please wear loose-fitting, comfortable clothing with sleeves that can be rolled up past the elbow.
  • Contact lenses, jewelry, make-up, finger nail polish, and dentures must be removed prior to the sedation treatment.
  • If you develop any illness prior to the sedation appointment, please call the office.
  • If you take any routine medications, please check with one of our doctors at the evaluation appointment for instructions regarding the medications.

CBCT 3D Imaging

Cone-beam computed tomography systems are radiographic systems used by dental professionals to analyze and reconstruct 3D images of a patient’s teeth, jaws and surrounding anatomy. The information obtained by means of CBCT imaging is useful in both diagnosis and precise treatment planning when two-dimensional diagnostic films are insufficient. Dental CBCT is useful for multiple types of analyses as well as the assessment of maxillofacial disorders or pathology. It is also most useful in surgical planning, including the accurate placement of dental implants.

Crowns & Bridges

When teeth are missing a series of changes that can impact your overall dental health and jaw function may be initiated. The adjacent teeth may start to drift or tilt into the space, and teeth in the opposing jaw may start to shift toward the area of the missing tooth. It is therefore important to replace the single tooth or multiple teeth that have been lost. One of the best options to prevent the consequences of shifting teeth and to restore full function to a small edentulous section in the mouth is a dental bridge.

A dental bridge replaces the missing teeth with artificial teeth called “pontics,” and is supported on the ends by prepared natural teeth. Once fabricated and fitted a dental bridge will be permanently “fixed,” or cemented into place. Like crowns, bridges can be made of either porcelain baked on to a metal substrate or many of the new ceramic materials that have been developed.

Laser Teeth Whitening

Teeth that have been stained or darkened by food, tobacco use, age, medications or injury can be lightened and brightened by means of a non-invasive process known as laser teeth whitening.

Teeth whitening or bleaching simply refers to any process that will make the teeth appear whiter. While there are many over the counter options for teeth whitening, the most effective and safest teeth whitening systems are the professional strength ones available at the dentist’s office. A dental professional whitening system offers a higher concentration of whitening components (hydrogen peroxide) and delivers them to the teeth in the most efficient manner to achieve optimal results. At our office we offer the “Futura 2400 with Polaoffice 38% hydrogen peroxide” professional laser teeth whitening system. Our teeth whitening system has been shown to produce the best results compared to other systems out on the market.

Some patients may not be candidates for teeth whitening due to excessive plaque/calculus build up, cavities present, excessive gum recession, smoker, hypersensitive teeth etc.. Therefore, a prior consultation is required.

Root Canals

Endodontics, or root canal therapy, is employed when the nerve supply to a tooth has been irreversibly affected by damage or decay. It is a way to prevent or help resolve a dental infection and save a natural tooth from extraction. A root canal is performed when there is enough sound root and crown structure remaining to eventually restore form and function to the involved tooth.

Inside every tooth is either a single central chamber or multiple ones that contain connective tissue, a nerve supply, and blood vessels. These core tissues, known as the dental pulp, help your tooth to grow and mature before it emerges into the mouth. A root canal procedure is required when this dental pulp is irreversibly damaged or has died.

Root canal therapy involves cleaning and shaping each canal, and then filling them with a special inert material. Following this they are sealed to prevent any subsequent infection. Once root canal therapy has been completed, the tooth should be fully restored as recommended.


Whether from disease, malnutrition, genetic disorders, or an accident sometimes it is necessary for an individual to have some or all of their teeth extracted. While this can be devastating, partial or full dentures can be fabricated to restore an attractive smile, provide needed support for normal facial contours and reestablish a highly functional occlusion.

A denture consists of natural looking artificial teeth set in a supportive base. It may be fabricated to replace either a small group of teeth, an entire upper arch, an entire lower arch, or used to restore both dental arches.

A complete denture refers to the replacement all of the teeth in a dental arch. It can be inserted either of two ways. It can be inserted some weeks after the extraction sites and all of the surgical procedures have had a chance to heal, or as an “immediate” denture placed the same day the last remaining teeth are extracted. Although an immediate denture offers the advantage of not having to go without teeth for any period of time, it can require multiple adjustments as the tissues remodel and heal following dental extractions or other surgical procedures.

In situations where some sturdy teeth remain, partial dentures can be fabricated. Partial dentures can achieve adequate retention and stability by having clasps on the teeth surrounding the edentulous areas.

In some cases added stability for the dentures can be provided by strategically placed implants.
