Implant

What is a Dental Implant?

A dental implant is an artificial tooth root that is placed in your jaw to hold a replacement tooth or a bridge. Dental implants actually look and feel natural, so you will not have any worries or discomforts about wearing them.

Its Benefits
  1. They are natural-looking alternatives to enhancing your smile and confidence.
  2. They allow you to eat and speak without pain or discomfort, and increases chewing efficiency.
  3. They can help prevent atrophy or shrinkage of your bone.
Types of Dental Implants

1. Endosteal (in the bone)
This is the most commonly used type and has various types such as screws, cylinders or blades surgically placed into the jawbone. Each implant holds one or more prosthetic teeth.

2. Subperiosteal (on the bone)
These implants are placed on the upper part of the jaw with the metal framework's posts protruding through the gum to hold the prosthesis. These types of implants are used for patients who are unable to wear conventional dentures and who have minimal bone height.

Procedure

Stage 1:
An incision is made in the gums and the implants are placed into the jawbone. The gums are then closed up and to allow healing to take place. It usually takes just about 3 months for the implant to integrate with the bone or longer if bone grafting is involved.

Stage 2:
The second and final stage is to secure the new tooth or teeth to the implant structure. Implants can support a single tooth, multiple teeth or dentures

Final Note

Implants as a solution to missing teeth has been practiced for a few decades. Generally, because of advances in implant dentistry over the years, dental implants can have success rates above 90% in natural bone.

Veneers

What is a Veneer?

Porcelain veneers correct stained, chipped, or crooked teeth. A glass-like, ceramic porcelain is placed on the surface of the teeth and patients can then have bright, straight, and natural looking smiles.

Its Benefits
  1. Covers worn enamel.
  2. Solves teeth wear and tear. It solved teeth problems such as chips, cracks or a generally uneven appearance.
  3. Solves uneven teeth.
  4. Protects the surface of a damaged tooth.
  5. Replace the need for a dental crown.
Types of Veneers

1. Composite Resin
It is one of the most popular and relatively new dental restorative material used today. It is aesthetically pleasing, insensitive to dehydration, and inexpensive. Compared to other forms of dental restorative materials, composite resin is much easier to manipulate, which is why composite veneers can be applied indirectly and directly, whereas porcelain cannot. A composite veneer may be directly placed (built-up in the mouth), or indirectly fabricated by a dental technician in a dental laboratory, and later bonded to the tooth, typically using a resin cement. They are also more affordable and easier to repair.

2. Porcelain Veneers
Porcelain veneers are tougher and more durable. Porcelain veneers are known to have a lifespan of 10-30 years. They also have a more natural tooth color. A porcelain veneer is fabricated by a dental technician in a dental laboratory and later bonded to the tooth.

Procedure

1. Teeth Preparation
Your teeth are prepared by removing a small amount of the front surface of the tooth, about 0.3 to 0.5 millimeter to allow space for the porcelain. Then the dentist takes an impression of your teeth. Keep the gums healthy. If your gums are not healthy, they will tend to bleed easily during the bonding of the veneers, which will contaminate and weaken the bond.

2. Second Veneer Appointment
The appearance and fit of the veneer is checked in your mouth to be sure that it will meet your esthetic and functional requirements

3. Third Veneer Appointment

The veneer is then bonded to the tooth or teeth at this point.

Crowns, Bridges, Dentures

  Crowns Bridges Dentures
What is it? A dental crown is a tooth-shaped "cap" that is placed over a tooth, covering the tooth to restore its shape and size, strength, and/or to improve its appearance. A dental bridge is made of a false tooth used to replace one or more missing teeth. They are worn into place. The surrounding teeth and gums will support the dental bridge. Dentures may be complete dentures (replaces all of the teeth and their adjacent tissues), partial dentures (bridge the gap between a missing tooth or teeth). It is a removable dental appliance made of acrylic resin and in some, a combination of metals.
