Definition and Components
A dental implant is a titanium post that is surgically placed into the jawbone to function as a replacement root for a missing tooth. It consists of three main components:
Implant Fixture: The titanium post that integrates with the jawbone.
Abutment: The connector placed on top of the implant fixture.
Crown: The visible part of the implant that resembles a natural tooth.
Procedure
Initial Consultation: Includes a comprehensive dental exam, X-rays, and 3D imaging to assess the condition of the jawbone and plan the implant placement.
Surgical Placement: The implant fixture is surgically placed into the jawbone under local anaesthesia. Healing and osseointegration (fusion of the implant with the bone) typically take several months.
Abutment Placement: After successful osseointegration, the abutment is attached to the implant fixture.
Crown Placement: Finally, a custom-made crown is attached to the abutment, completing the restoration.
Materials Used
Titanium: Most common material for the implant fixture due to its biocompatibility and strength.
Ceramics and Porcelain: Common materials for the crown due to their aesthetic properties and durability.
Benefits:
Durability: Implants can last a lifetime with proper care.
Aesthetic: Crowns provide a natural look, matching the surrounding teeth.
Functionality: Restores normal chewing and speaking abilities.
Bone Health: Stimulates the jawbone, preventing bone loss.
Success Rates
Dental implants have a high success rate, typically between 95% and 98%, depending on the patient’s oral health, the skill of the dentist, and adherence to post-operative care.
