Dental Implants

A Dental Implant is an artificial tooth root that is surgically inserted into the jaw to support/hold.

Either a single tooth bridge or multiple implants for a full arch of teeth

An implant is typically a titanium screw with a smooth, roughned or treated surface. Most implants are made of commercially pure titanium.

Dental implants are a viable option for replacement of teeth lost to
A. Tooth decay/Caries
B. Trauma
C. Periodontal Disease

An Ideal candidate for a dental implant should be in good general and oral health.Any Systemic disorders like Diabetes, Hypertension should be under control with medication.

Adequate bone is essential to support the implant, if there is inadequate bone,a bone grafting procedure may be required in addition to the implant surgery.

The discipline of implant dentistry is prosthetically driven, ie the design,shape, number of teeth to be replaced is determined prior to the number and position of dental implant to be used.

Detailed treatment planning prior to the start of implant surgery is essential to maximize the success of the treatment.
A. Study models
B. X-rays/CBCT scans
C. Photographs
D. Surgical splint fabrication

All or some of these may be required to plan implant surgery.

Vital structures such as the inferior alveolar canal/nerve in the lower jaw/mandible, or the floor of the sinus.nasal floor, can be predetermined with great accuracy with a dental CT scan or CBCT.

A surgical stent may be fabricated with the help of CT scan.This is popularly called guided surgery and can facilitate multiple implant placement with a greater degree of accuracy.

The basic implant procedure involves preparation of a recipient site in the jaw called an : osteotomy.

A precision handpeice controlled by a device called phsiodispensor prepares the osteotomy. The speed and torque of the drilling is controlled by the phsiodispensor.

To prevent any damage to the bone chilled normal saline is used as a coolant.

Different approaches to place dental implants are available
A. Immediate post extraction
B. Delayed Immediate post extraction ie 2 to 3 weeks after extraction.
C. Late , 3 months or more post extraction.

An important point to remember is that research shows that upto 50% of bone is lost in the first year post extraction.

Dental implants enjoy a success rate of above 90%.

Factors affecting the success are primarily related to improper treatment planning. General health of patient, habits like smoking, quality /quantity of bone, patient oral hygiene, maintenance and of course skill of operarator.

A primary reason why increased number of patients from the UK and US are seeking dental implant treatment , outside of these countries is the prohibitive cost.

A single implant and crown with a crown in Uk can cost upto 2000 to 3000 Pounds.

Full mouth tooth replacement can cost upwards of 20000$ in the US.

This compares with costs of 30000 to 40000 INR for asingle implant to around 3,00000/ to 500000/- for full arch implant supported prosthesis.

Implants used in Dentotal are Nobel Biocare,Sweden and 3 I from the US. These implants enjoy lifetime warrantees.
