History of implants
Dental implants in their own way have been a fascination to mankind since 2500 BC. Missing teeth have been replaced in one form or the other by the ancient Egyptians with gold ligature wires to stabilize deteriorating health of teeth. In 16th century Europe several substances were used to stabilize periodontally compromised teeth. Dr. John Hunter recorded every detail and anatomy of the mouth and jaw. He then suggested implanting teeth from one human to another. By the 19th century Dr. EJ Greenfield and brothers Dr. Alvin Strock and Dr. Moses Strock began experimenting with orthopedic screw fixtures. With their observation on how hip bone implants were made, they also prepared modalities to support teeth. The patented cylindrical endosseous implant was internally and externally threaded by Dr.P.B.Adams and Formiggini considered as the father of modern implantology developed the post-type endosseous implant. More recently in the 1980s experiments with several metals helped fabricate dental implants and the endosseous root-form implant came into being. This paved the way for the introduction and use of titanium in dental implants along with surfaces and coatings that reduced healing time during osseointegration.
Success and failure of implants
The success and failure of implants depend largely on the quantity and quality of bone availability and patients’ age. Besides these other factors such as location of placement of implant, the axial loading, length of the implant, practice of oral hygiene and maintenance of the implant play a very important role in its success. Primary reasons for failure of implants are chronic periodontitis, uncontrolled diabetics, poor quality of bone, smoking, poor oral hygiene post Implant placement, irregular follow up after implant placement, untreated dental caries, absence of soft tissue and hard tissue integration to the implant, and inappropriate design of the prosthesis. Advanced age and parafunctional habits can also lead to failure of implants.
Implant supported dentures
Implant supported dentures are overdentures that are supported by artificial implants. Implant-supported dentures require enough jaw bone to embed the fixtures. Especially advantageous when there are no teeth these dentures are fashioned for the lower jaw due to instability of regular dentures in this area. Upper jaw dentures are generally stable and don’t need any additional implant support. Fixed crown and bridge work are an option available with implant-supported dentures as a permanent choice.
Types: There are two types of implant-supported dentures:
Bar-retained dentures: A thin metal bar in the shape of the jaw is placed along its curvature and the implants are attached to the jaw bone. Clips are fitted to the bar and the dentures to place them securely.
Ball-retained dentures: These are stud-attachment dentures where each implant contains a metal that fits another attachment which is ball-shaped and fits into sockets on the denture.
Advantages of implant supported dentures
Speech: Implant supported dentures have a positive ability to enhance speech especially involving the upper jaw due to greater stability of the dentures.
Hygiene: Removable implant supported dentures can be cleaned regularly to avoid gum disease and bone loss.
Aesthetics: Facial aesthetics, balance and tissues are restored with implant supported dentures.
