Implants: Implants are narrow pins made of bone-compatible pure titanium and are inserted into the jawbone. The moving teeth can be attached to these implants. It requires about 3 to 6 months for the bone to grow and be repaired around the implant. When choosing an implant, available bone amount, bone strength rate and implant insertion time are considered. If sufficient amount of bone is not available for implant insertion, in certain circumstances, bone may be grafted from elsewhere. Moreover, various methods of applying implants including screw-based and screw-free (glue-based) methods may be selected according to bone hardness. The implant can be replaced immediately after losing or pulling (or extracting) a tooth or after a long recovery. The shape of the implant is similar to a natural tooth root. After tooth loss, in case of not quickly replacing it with the implant, it is possible to have weakened bone and reduced ability to chew and adjacent crooked teeth. If delayed implant insertion is recommended, smaller and cylindrical implants are used since less amount of bone is available. The place for implant insertion and correct implant type are suggested after examination by the dentist, taking into account other conditions. The volume and density of the jawbone; number, position and strength of one’s natural teeth; gum conditions; and condition and number of opposite jaw teeth are among the important factors during the examination. Implants are used in the following cases:
- The distance between the front teeth due to a tooth loss such that the adjacent teeth are natural: Loss of teeth can be due to caries, gum diseases, or accidents. If the missing teeth are in the esthetic area, in addition to beauty, teeth health is also affected. The long edentulous period causes the opposite jaw teeth to grow to the missing teeth space and thus causes the displacement of the upper and lower teeth and loss of proper occlusion. In this condition, the chewing operation is also affected, and the lower jaw joints become painful.
- A large gap between the teeth due to the loss of one or more teeth such that the adjacent teeth are natural: The greater distance between the teeth shows the same, but more severe, effects of a single tooth loss. Lack of aesthetics, imbalance in chewing force distribution, pain in the lower jaw joints, and speech problems are among the issues reported by patients.
- When one or more teeth are missing from the end of each dental arch and natural teeth are available only in one side: Loss of strong teeth in the back of the dental arch that are responsible for chewing and preparing food for digestion can damage chewing gestures. The remaining teeth move toward the empty space and the contact between the teeth is lost. Moreover, the opposite arch teeth move toward the space and the problems of the lower jaw joints also occur.
- When all the teeth of one or both jaws are missing: The complete edentulism of the maxilla and mandible together or alone can lead to many problems. Chewing and talking are the main problems of edentulous patients. Since the teeth which support facial muscles no longer exist, the patient will present an aged facial expression. Blood coagulation, metabolic, mucosal and bone disorders; low dental spacing; or inappropriate position of the maxilla and mandible teeth are limiting factors in implant insertion.
