Porcelain crowns have been a staple in cosmetic dentistry for years. It gives the dentist and patient a much more aesthetic appearance as a final product. In the past crowns and bridges were traditionally made of porcelain fused to metal (PFM). With the development of modern porcelain, which are incredibly strong and reflect light similar to natural teeth, full porcelain crowns can be used in most areas in which porcelain fused to metal crowns were used. This is especially true in a cosmetic area of the mouth.

Porcelain crowns are very versatile and used in many ways. The cosmetic enhancement use of porcelain crowns include, changing color of teeth, closing gaps between teeth, fixing teeth that are crooked or crowded, changing shape or size of teeth. Porcelain crowns are also used to cover and protect damaged teeth, (tooth that has a root canal, broken, cracked, large fillings), and to act as a new tooth in the case of dental implants. Their versatility gives the dentist a greater flexibility in using them to fix potential issues for the patient.

The first step often times includes impressions for study models and photos. The patient and dentist can then discuss and plan what the end result should be. The treatment includes preparation of the tooth surface for the porcelain crowns. The outer enamel and sometimes a bit of  the dentin are removed. This allows room for the porcelain crowns to fit over the teeth and be in perfect cosmetic alignment with the others. Impressions are taken of the newly reshaped teeth and temporary crowns are made.  The porcelain crowns are custom made in the laboratory. The porcelain crowns are then cemented or bonded onto the teeth using an adhesive bonding material. The placement of the porcelain crown will normally take about 30 minutes (depends on amount of porcelain crowns being placed). Once completed,  the patient can eat normally and enjoy the benefits of a beautiful new porcelain crown that matches and blends perfectly with the patients existing teeth. Only you and the dentist should know anything was done.

Advantages of All Porcelain Crowns

-No PFM gray or black lines at the Gum Line of Teeth. You may have noticed a person with a dark line in the gum area along a PFM crown edge. With PFM crowns, the soft tissue around the tooth can recede over time. This allows a reveal of the metal framework underneath. This cannot happen with an all porcelain crowns because they are metal free.

-Perfect Fit. Porcelain crowns are created in state of the art facilities. Porcelain crowns will fit so well you will even forget they are present.

-Cosmetically Perfect Match. All porcelain crowns have the ability with modern porcelains to match your existing shade of tooth color as well as mimic the light reflecting properties of your natural teeth. Porcelain crowns will be undetectable to anyone but you and your dentist. Dental porcelain can be shaped custom colored and sculpted to closely copy the look of your own natural tooth enamel. All the while providing the desired strength and resilience.

Some disadvantages of an all porcelain crowns:

-Higher cost over traditional PFM crowns.

-Durability. While porcelain crowns are very durable, they do not have the flexibility of natural teeth, they can fracture. Avoiding certain foods may be necessary. For example, Biting into sandwich with a hard bread. Patients who grind and clench their teeth will need to be fitted with a mouth guard to protect the porcelain crown from unnecessary and excessive pressures.

-Porcelain crowns may need a bit more reduction of tooth structure than traditional PFM crowns.

-Sensitivity may happen for a short time, (hot, cold sensitivity), especially with bonded porcelain crowns.

Follow-up Maintenance of All Porcelain Crowns

The maintenance of porcelain crowns is actually very easy.  They require routine brushing with non-abrasive fluoride toothpaste and regular flossing as well as regular visits to the dentist. A follow-up appointment will be scheduled to evaluate the porcelain crowns about 2-4 weeks after they are placed in the mouth This allows the dentist to review the work with tissues all healed and see how your oral tissues are reacting to the crowns. Even if you think the crowns are successful, this appointment is an important part of your future oral health.
There are several types of all porcelain crowns generally used in dental offices today. They have all proven to give the best cosmetic dental results.
-Zirconia Crowns or Lava Crowns (made by 3M Espe). This type of all porcelain crowns are made out of a zirconium core with porcelain pressed or layered over the crown to follow the natural contours of teeth. These crowns offer good strength and durability. Due to great strength, the material can be used to make a bridge.
-Procera Crowns (made by Nobel Biocare). These are made of an Alumina core with porcelain pressed or layered over the crown to follow the natural contours of the teeth. These crowns offer great strength and durability and are esthetically quite beautiful. Often used in the back of the mouth, (premolars, molars), these are cemented in with traditional cement and have less post-placement sensitivity.
-Empress II Crowns (made by Ivoclar Vivadent).These highly cosmetic porcelain crowns are used in the front of the mouth. They are used mostly for cosmetics, are very beautiful, but can fracture.
-eMAX Crowns or IPS e.MAX Crowns (made by Ivoclar Vivadent). These porcelain crowns are entirely made out of porcelain without a underlying framework. The absence of this framework offers a great advantage over Zirconia crowns, Lava crowns and Procera crowns in that e.MAX crowns allow for more light transmission through the crown translating to a more superior cosmetic dental result. The strength of these porcelain crowns is such that they can be used in any area of the mouth, can be made thinner than most porcelains, and can be used for an implant without much worry of fracture.
Cosmetic Dentistry is the art and science of creating a beautiful smile. The all porcelain crowns are just one more tool that the dentist can use to give you that smile you’ve always dreamed of.

We don’t often give much regard to the importance of the bone our teeth sit in until there is a problem. The bone not only serves as the foundation for our teeth but it also plays a big part in our visual aesthetic appearance. Bone can be lost by tooth removal or periodontal disease. If a tooth is missing or removed, the bone may collapse into the empty socket and cause a sunken appearance to our cheeks or jawbone. A bone graft can restore these problems caused by dental disease or those that result from an accident. One of the main reasons for bone grafts in modern dentistry is to form a good foundation for dental implants.

What is a Bone Graft?

A bone graft is the replacement or augmentation of the bone around the teeth. Bone grafting is a term used to describe a variety of procedures used to add or build bone so that dental implants can be placed.
Dental Bone Grafting
A bone graft typically involves adding bone or bone like materials to the jaw. The bone graft can be your own bone (also called Autologous  bone), synthetic bone, be processed bone obtained from a cadaver (also called Allograft), or can even come from bovine/cow sources (these types are also called Xenografts). After grafting, you generally have to wait several months for the grafted material to fuse or become one with the existing bone structure.  Processed bone grafted materials either cause surrounding bone to grow into the graft or cause cells around the graft to change into bone. Autologous bone transplants bone cells or a block of bone that fuses to the jaw.

Implant Dentistry

It is often used to augment bone to allow for a more successful implant placement. A few reasons for bone grafting in implant dentistry include:
1) Augmenting bone in the sinus area to allow for implant placement.
2) Augmenting bone to enhance the fit and comfort of removable prostheses (dentures)
3) To enhance aesthetics of a missing tooth site in the smile or aesthetic zone. This zone is generally defined as the visible area seen upon full smile, including the teeth, gingiva, and lips.
For a dental implants to be a success, the patient must have sufficient bone in the jaw to place the implant into.
Assumptions were once made that if a patient did not have sufficient quality or quantity of bone in their jaw they would not be suitable candidates for dental implants. Today, thanks to the exponential advances in dental techniques, materials, and technology, patients with insufficient bone in their jaws can have the bone rebuilt using bone grafting.

Bone Grafting Procedure

The actual bone grafting procedure is quite straightforward. A dentist will assess the quantity and quality of your bone during the treatment planning stages. It will be at this time that he/she will determine if there is a need for bone grafting. Then your dentist will review the different types of bone grafts with you and decide which will be the most suitable for your individual case.

Once this has been decided the bone graft procedure can be performed. The actual procedure requires the dentist to place bone under the gum tissue at the site where the bone graft is needed. The dentist will then be able to place the bone to be grafted onto the site and then cover it with a membrane for protection. Membranes are often used to help stabilize the bone graft as well as keep the gum tissue from invading the healing bone graft. The gum tissue will grow at a much faster rate than bone, therefore, membranes are used to prevent gum tissue from growing in and displacing the bone graft before it fully matures.This membrane is also used to protect the boneDental Bone Grafting from any germs found in the oral cavity and ensure that the area is perfectly clean to allow the healing process to take place. Finally, the area is closed and the tissue is stitched into place. Bone graft healing time is usually right around 4-6 months. But this can vary from patient to patient. Patients are given a prescription for antibiotics to take following their bone graft. Antibiotic mouthwashes can also be prescribed to preserve the health of the gum covering the bone graft.

On follow up visits the dentist will check on the success of the bone graft by taking x-rays to determine the height and width of the new bone. Once this has been verified as satisfactory, and the site of the bone graft is completely healed, the next stage of the dental implant process can begin.

Dental bone grafts for the purpose of dental implants has a very high success rate. But there is always a possibility that the bone graft will not work as planned, even if your own bone was used. Bone grafts are not rejected by the body like organ transplants. There is still some mystery as to why some bone grafts fail. We do know that certain people (for example, smokers, diabetics, patients with poor dental hygiene) have higher risks of graft failure.

A failed graft will need to be removed. Once healed properly, you and your dentist may choose to place a second graft.

A bone graft gives the implant dentist and patient one more tool to achieve a successful outcome to just about any implant treatment.

Have you ever caught yourself staring at the perfect smiles seen on TV, in the movies, and in magazines . . . the smiles of  Hollywood actors and actresses, and models? Have you ever wondered, “How did they get that perfect, white smile? Odds are, those celebrities were not born with pearly white smiles. These smiles were likely designed and created just for them with the help of a cosmetic dentist. The good news? Anyone can enjoy the perfect Hollywood smile, with the assistance of a cosmetic dentist and porcelain veneers.

Porcelain veneers (also referred to as porcelain laminates) are super thin, custom fabricated shells of tooth colored porcelain designed to cover the front surface of teeth to improve your smile’s overall aesthetic appearance. These shells are adhesively bonded to the front of the teeth changing their color, shape, width, and/or length. Versatile and very strong, porcelain veneers are used in a variety of ways to transform your smile, from complete smile makeovers to repairing a chipped tooth.

Porcelain veneers are custom made from a high quality dental porcelain that has similar light reflecting properties as our natural teeth. Porcelain veneers are excellent at resisting stains and they mimic our natural teeth’s light reflecting properties. They are the cosmetic dentist’s greatest tool for elevating a normal smile to a Hollywood smile.

Porcelain Veneers arecosmetic dentist regularly used to fix the following issues:

-Teeth that are stained or discolored. Teeth can become stained or discolored from root canal treatment, from tetracycline or other drugs, excessive fluoride, or the presence of large resin fillings that have discolored over time.

-Teeth that are worn down from use or grinding of teeth.

-Teeth that are broken or chipped.

-Teeth that are misaligned, uneven, or irregularly shaped. Porcelain veneers are sometimes referred to as “Instant Orthodontics”.

-Teeth with gaps or spaces between them. Porcelain Veneers are able to cosmetically close those spaces.

Making the decision to have porcelain veneers is the first step. The entire process usually takes 3-4 visits, one for a consultation and two to make and apply the porcelain veneers. There is sometimes an added appointment following the consultation where the dentist will show the patient a mock up model. This model will be of your teeth where the dentist has waxed onto those teeth what the porcelain veneers will look like on your smile. It is a great visual reference for you to decide the course of treatment for you. This can also be done via software on a computer. One tooth or many teeth can simultaneously undergo the treatment described in the following paragraphs.

Consultation/Diagnosis and Treatment Planning. This first step involves your aCosmetic Dentistctive input. Explain to your dentist what you want in the final result. During this appointment, your cosmetic dentist will examine your teeth to make sure porcelain veneers are appropriate for you and explain to you what the procedure involves and some of its drawbacks. They may take X-rays and possibly make impressions of your teeth as study models. These models will be used by the dentist to do a mock up of the final result. The dentist will prepare the teeth on the model and sculpt wax over them to give you a visual representation of the final product. This is an important step.

Preparing the Teeth for Porcelain Veneers. A dentist must remove  about 1/2 millimeter of enamel from the tooth surface, which is an amount nearly equal to the thickness of the porcelain veneers to be added back to the tooth.  Before beginning, you and your dentist will decide the need for a local anesthetic to numb the area. Next, your dentist will take an impression of your teeth. This model is sent out to a dental laboratory, which in turn constructs your custom porcelain veneer. It takes about 1-2 weeks for the laboratory technicians to complete the process. Temporary veneers are placed using a resin material until the final veneers are ready.

Dental Bonding. Before the porcelain veneers are permanently bonded to your tooth, the dentist will check for fit and color by temporarily placing it onporcelain veneers the tooth. If they fit properly and the color shade is correct the dentist will go on to prepare your tooth, your tooth will be cleaned, polished, and etched (this is a process whereby your tooth surface is roughened up chemically at the microscopic level).  A special adhesive is applied to the porcelain veneers and the veneer or veneers are methodically placed on your tooth. When the they are in the right position, your dentist will apply a special light to the porcelain veneers. This activates chemicals in the adhesive, causing it to cure. The final steps involve removing any excess adhesive, evaluating your bite and making any final adjustments in the porcelain veneers as needed. Your dentist may ask you to return for a follow-up visit in a couple of weeks. This is to ensure you are happy with the final result as well as checking the gum tissue surrounding the new porcelain veneers.

There are some disadvantages to porcelain veneers:

-The procedure is not reversible.

-Porcelain Veneers are not repairable. If they break, a new one will need to be custom  fabricated in the laboratory.

-The color cannot be changed once the porcelain veneers are in place. So both dentist and patient must be sure they are happy with color prior to final placement of the porcelain veneers. It does happen on occasion that the color is not what is desired from the laboratory and they are sent back to be remade. It is of the utmost importance for the patient to be ahppy and satisfied with the final result.

-Porcelain veneers can fall off or chip. The material is very strong but patients who grind their teeth, bite their nails or chew on pencils will be more susceptible to this occurring.

-The teeth under the porcelain veneers are still susceptible to tooth decay. Patients need to be made aware of maintaining proper oral hygiene.

Porcelain veneers can be brushed, and flossed just like your own teeth. You should not even know they are in your mouth as they are bonded to your natural tooth sstructure.

Imagine. In just a few short visits, you can have an amazing Hollywood smile . . . a smile that has been custom designed just for you. A smile that is straighter and whiter than you could have imagined. You’ll be looking younger and feeling more confident. And it’s all possible with your cosmetic dentist and porcelain veneers.
