Dental implants are artificial devices that are used to replace the roots of natural teeth. It has the same appearance as of natural tooth. These implants are mainly made of titanium material. Dental implants are used in the empty space of lost or removed tooth. The natural tooth may be affected from any injury or disease condition. The dental implants are mainly aimed for people who find it difficult to use conventional denture. They provide highly stable, firm, and visually attractive teeth. As per the need of the patient, implants can be used to replace a single tooth or multiple teeth. The lost confidence of the patient to speak, laugh and chew can be easily restored with dental implants.
Types Of Dental Implants
Modern techniques mainly use two common types of dental implants:
- Endosteal (Inside Bone)
Endosteal implants are commonly used to replace original tooth. These implants include cylinders, screws, or blades to hold replacement tooth. Surgical method is used to place these implants under the required jaw bone. Each implant is capable of holding one or more prosthetic teeth. This implant is more suitable for patients who have bridges or removable dentures.
- Subperiosteal (Outside Bone)
In people, who have difficulty in wearing conventional dentures or have less bone height, subperiosteal implant is the best option. The implants are fixed on the upper portion of the jaw. It is placed in such a way that the metal framework’s post points out through gums to hold prosthesis.
Good Candidate For Dental Implants
A candidate who is ideal for dental implants should have following features:
- Good oral hygiene
- Appropriate jaw bone structure to support implant
- Gum tissues must be healthy
- No existing medical condition such as blood pressure, diabetes, etc
Prior to treatment, a series of tests are done to analyze the tooth deformity. The tests include physical examination along with radiography and 3D Nobel guide system test. According to the results obtained, the type and procedure for dental implant is chosen. The treatment can be done either in a single-stage process or a two-stage process. Conventional treatment procedure mainly opts for two-stage process. However, in both treatments, initially the dentist creates a model of the teeth. It is based on the impression of bite of patient’s teeth.
In single-stage procedure, the implant is attached to the jawbone of the required tooth. A small connector post called abutment is also used in this treatment. Abutment is used to to hold the new tooth in fix position. Crown, which acts as the replacement tooth, is then connected to the abutment. This process generally requires 3-5 outpatient visits within a week for completion.
A conventional two-stage treatment procedure includes:
- First stage
In the first stage of treatment, the desired implant is kept on the jaw of the needful tooth. The entire arrangement is then covered with the gums.
- Second stage
After the completion of first stage, the arrangement is left untouched for about 3-6 months. Later, the implant is properly measured and checked for any damage. If found correct, the artificial teeth or prosthesis is attached to the implant.
An overall healthy body is a prime factor for the success of dental implant procedure. It is essential to maintain good oral hygiene. The implants should be properly brushed and flossed, without metal objects, at least two times in a day. This helps to keep implant plague-free and clean. Adequate medications will be provided by the doctor to relief temporary pain and other discomforts of treatment. Frequent Cone Beam CT Scan of operated teeth is beneficial. It gives an accurate and clear view of implant structures, nerves, bone volume and quality, and sinus anatomy.
Dental implant treatment often poses some health risks which includes:
- Damage to nearby structures of tooth
- Sinus disorders
- Numbness in gums or teeth
