Implants
Implant
is an artificial tooth root in the form of screw placed in the
chamber where the missing tooth was. The implants can be used to
support a bridge. They have been evolved greatly in terms of their
material (titanium) and their placement technique. Thus we achieve
excellent long term results.
Requirements for implant placement are:
- Patient history free (contraindicated in patients who are anticoagulated patients, with no controlled diabetes, autoimmune disease, scleroderma, lupus, etc.)
- Satisfactory thickness, height, bone density. Healthy periodontal situation and psence of some teeth.
- Ensuring good oral hygiene of the patient.
Subject to the above conditions, the implants have success. The modern and reliable implant manufacturers offer lifetime warranty certificates.
Crowns, bridges
The
partial restoration of tooth loss. using existing teeth as supports.
The materials of construction of bridges and crowns vary, the most
popular materials are porcelain and zirconium.
Zirconium is a new material in cosmetic prosthesis. Material like titanium and produced by means of digital computer CAD / CAM.
Advantages of the excellent Esthetic result (no metal frame), it is very corrosion resistant, biocompatible and very strong material with minimal risk of fractures. The only disadvantage is the high additional costs.
Porcelain is the most popular recovery material. The metal-constructions consist of a metal frame, which can be basic metals (palladium, gold, titanium, etc.) covered by porcelain.
Have
high strength, excellent cosmetic result. There and ceramic
structures where a thin surface porcelain fits over the tooth to
give the best to the shape and color of the tooth.
Needs less grinding the tooth in relation to the metal-structures. But most sensitive to breakage compared to other constructions. Should the patient should avoid hard foods too. So the ceramic suited mainly to the anterior teeth.
Dentures (partial - full size)
-
If all teeth are missing then there is the need for dentures to be fitted.
- In partial dentures the missing teeth are replaced by some thermoplastic materials without metal or metal frames and hooks or precision links.
- Implanted dentures: partial and full dentures based on implants or tooth roots healed.
Treatments that are quick and easy processed Esthetically and functionally restore the edentulous patient. Have low costs compared with reconstruction with implants.
As disadvantages include:
- The difficulty of adjustment for the speech or chewing the early days
- Require regular monitoring by the dentist due to absorption of the gums so must be recharged to fit perfectly the mucosa every time and have the best retention.
