According to a survey conducted during 1999-2004 by the National Health and Nutrition Examination Survey’s (NHANES) on the loss of dentition, the prevalence of tooth loss in America has reduced significantly since the early 70s. This is attributed to the better understanding and awareness regarding oral care amongst the masses. However, teeth loss due to caries, periodontal disease, metabolic conditions, trauma, and injury still continue to plague the society.
Although most of the twentieth-century dental treatments relied heavily upon Dental Bridges and Dentures, the underlying problems of long-term bone loss remained unanswered and untreated. The milestone innovation of modern Dental implants has made a revolutionary change in the bone loss treatment strategies. Research on Dental Implants is continuously improving the designs and techniques, thereby enhancing the success rates of dental implants.
Chinese civilization archaeological exploration data about 4000 years, reveals that bamboo pegs were used to replace missing teeth. The use of materials like seashells, jade, and teeth of animals, is also documented from these excavations.
A dental implant is a metal post that acts as a replacement for the root/roots of a missing tooth/teeth. The implant is surgically drilled or screwed into the jaw bone to secure a dental prosthesis like a crown, bridge or denture. Dental implants can also be used in other parts of the skull to support facial prostheses after an injury or trauma, or during Orthognathic surgery.
A dental implant consists of 3 building blocks:
1. Implant fixture.
Implants are indicated for all toothless gaps, provided no contraindicating conditions persist.
There are certain conditions which do not permit implant placements, since this may jeopardise the life of the patient. These conditions are known as Absolute Contraindications. Others are referred to as Relative Contraindications,
1. Single missing tooth — single tooth implant.
2. Multiple missing teeth — implant supported bridge.
3. Loss of entire dentition — implant supported fixed or removable dentures.
If one has decided to get a bridge for the missing teeth, there is always an option to either go for an implant bridge or a conventional bridge.
Minimum 2 to 4-5 implants in the edentulous arch to support a denture
A dental implant acts as a sound basis for both fixed and removable dental prosthesis. This creates a positive impact on the oral crippling of patients with lost teeth. Implants render their fabulous effects:
For an edentulous patient, the option of possessing a dentition, which appears extremely natural and without the botheration of removing it every night, storing with proper care and maintenance seems too good to be true. This is now very much attainable with implant supported bridges.
Before undertaking an implant placement, a thorough clinical evaluation of the patient's general and oral health is performed.
Particular care is taken in high-risk patients, in consultation with the general physician.
When the implant opening is covered with a healing cap, during the implant placement surgery, the healing cap protrudes through the gums after gum tissues are sutured.
For successful osseointegration of implant there should be:
1. Minimum 1 mm of bone available all around the implant
2. Minimum 1.5 mm of bone, if implant is next to a natural tooth
3. Moreover, minimum 3 mm of bone, if implant is adjacent to another implant
Sinuses are air spaces in the maxilla on either side of the midline. The air space of maxilla is known as Maxillary Antrum or sinus. Sometimes the root tips of the rear teeth of the maxillary arch touch or lie in the sinus.
Implant Science is a multi disciplinary approach.
The general dentist oversees the pre-implant foundation, by taking care of any fillings, root canals, and scaling procedures.
This chapter deals with the instructions, which are simple and easy to follow, for post dental implant care and maintenance of the same to ensure success and longevity of the implant.
Implant failure can be due to faults on the part of the operator, carelessness by the patient, or factors beyond control, such as less than optimal general and oral health conditions.
The cost of dental implants varies in different parts of the world. It is not covered by insurance. The estimates of which are on the higher side of the graph amongst the various dental procedures.

It is a best possible treatment option available for replacement of missing tooth or teeth.
