It is not always possible to restore a tooth alignment using regular prosthesis. It is dangerous to restore significant dental defects (3-4 missing teeth or more) using fixed dentures. In such cases masticatory stress on the abutment teeth becomes excessive and affects dental abutment ligamentous apparatus destructively. This kind of prosthesis is short-lived and causes the loss of the abutment teeth. False teeth implantation can reduce masticatory stress on the abutment teeth and distribute it evenly without harming natural teeth.
Dental implantation is a method of implant insertion into the bone tissue of the jaw to support fixed and removable dental prosthesis.
Dental implantation has a number of advantages over traditional prosthesis methods: a patient receives excellent aesthetic results under optimum operating conditions, i.e., chewing, speech, etc.
Advantages of dental implants:
• Dental implants can replace a defective dentition without the preparation (grinding off) of the neighboring teeth.
• Dental implants can replace dental defects of any length and location.
• Dental implanting technique makes it possible to fabricate fixed structures even to replace the teeth in a completely edentulous jaw.
• Removable denture abutting on dental implants will be much better fixed compared to conventional dentures, which, in its turn, increases the patient's self-esteem and adds to their confidence.
• Edentulous bone becomes devoid of functional load and atrophies quickly. Early dental implantation ceases bone loss in the area of the missing tooth. Dental implant imitates physiological masticatory stress on the bone produced by natural teeth.
• Modern dentistry in some cases can allow for the dental implantation immediately after tooth removal and fabricate a crown almost immediately.
• There are situations where traditional methods do not help the patient and dental implant is the only alternative.
Indications for implantation
The use of implants in the end of the dentition when the last few posterior masticatory teeth are absent makes it possible to avoid a partially removable denture prosthetics. In that case, you can fill the defect of a tooth alignment with a removable dental bridge, which is much more habitual and comfortable than a removable dental bridge.
Dental implants are recommended to edentulous patients with or without the atrophy of the alveolar processes, to patients who find it impossible to use removable dentures because of the increased gag reflex, allergic reactions to plastic, innate and acquired jaw deformation. Quite often dentists come across the problem of fixing fully removable dentures, especially when a patient suffers from an atrophy of the alveolar process in the mandible. In such cases, the implantation of artificial teeth makes it possible to fabricate a partially removable denture and fix it to the implanted teeth safely. Prosthetic bed of these removable dentures takes a much smaller area, patients get used to such prostheses more quickly and use them successfully.
In some cases it is possible to restore a fully edentulous jaw with a fixed dental bridge resting on implants.
Dental implantation is carried out in young and middle-aged patients. However, elderly patients in good general health with no contraindications to dental implantation can also be recommended this procedure.
Contraindications for dental implants:
• Chronic diseases (e.g., tuberculosis, collagen autoimmune diseases, like rheumatoid arthritis, etc.).
• Serious cardio-vascular diseases.
• Endocrine diseases (diabetes, toxic goiter, pituitary or adrenal glands dysfunction).
• Skeletal system diseases, which reduce its regenerative capacity.
• General connective tissue diseases (lupus, scleroderma).
• Diseases of blood and blood-forming organs.
• Mental illness (psychoses and neuroses).
• Radiation sickness.
• Chronic alcoholism.
• Drug addiction.
• Malignant tumors.
• Relative common contraindications are vitamin deficiency, specific diseases (syphilis, actinomycosis), pregnancy, infectious diseases, periods of general health deterioration, the exacerbation of inflammatory chronic diseases in various organs and tissues.
• People who do a physically demanding job, take part in traumatic and extreme sports are not recommended to use dental implants.
• Absolute contraindication for dental implants is the patient's poor oral hygiene and their unwillingness to maintain good oral hygiene in the future.
Dental implantation procedure
• Preparation of the patient's mouth for dental implantation.
• Surgery to insert an implant.
• The attachment of a titanium abutment - a connector post between an implant and a crown, bridge or denture.
• Prosthetic works, after the implant has bonded with the bone completely, which happens in 3 to 6 months.
After dental implantation it is important to conscientiously perform oral hygiene procedures, have regular professional dental cleaning, visual monitoring of tissue surrounding the implant and radiological control; it is not recommended to smoke because smoking dramatically reduces the success of dental implant treatment.
