Single Implant Crowns
A dental implant is a "root" device, usually made of titanium, used to support restorations that resemble a tooth or group of teeth to replace missing teeth.
The dental implants are root-form endosseous implants, i.e., they appear similar to an actual tooth root and are placed within the bone. The bone of the jaw accepts and osseointegrates with the titanium post. Osseointegration refers to the fusion of the implant surface with the surrounding bone. Dental implants will fuse with bone and thereafter when the implant is properly integrated in the bone then it can be finally loaded with the dental prosthesis. Dental implants can be used to support a number of dental prostheses, including crowns, implant-supported bridges or dentures.
SINGLE IMPLANT CROWNS
This type of implant is used to restore a single tooth, in place, where tooth is missing or where the extraction is to be done followed by immediate placement of implant.
After completing the radiographic and CT section study if required, implant can be placed under local anesthesia. The site is prepared by consecutive osteotome drills and implant can be placed with precision and the site can be sutured if required.
In the single stage implant placement usually done in the anterior region, the implant is placed in the prepared site and next the abutment (which support the tooth) is placed over the implant and a temporary crown can be given just after placement of implant. Care should be taken that the temporary crown do not come in contact with the opposing tooth to prevent transfer of uneven forces while the implant integrates with the bone.
However in two stage implant placement the implant is placed in the prepared osteotomy site and is sutured in place. After a period of about 4-6 months, the implant is exposed over which abutment is placed and final prosthesis can be given.
There are cases when the implant needs to be placed in the region where the extraction has been done immediately. In these cases the extraction is done carefully without causing any trauma to the bone and the extraction site is prepared by means of osteotome drills and implant can be placed. Then after a waiting period of 4-6 months the implant can be loaded with final prosthesis.
