The bonded bridge is a fixed restoration that uses bonding technology to restore individual missing teeth without grinding or with less grinding of healthy adjacent teeth. It is mainly suitable for patients with few missing teeth and good condition of abutment teeth who do not want to grind more teeth. The advantages and disadvantages of bonded bridges compared to traditional fixed bridges: 1, less tooth grinding Bonded bridges rely mainly on bonded retention, providing restorative retention and support of the healthy adjacent teeth less wear, less damage. 2, no anesthesia bonded bridges due to less tooth grinding, generally do not require anesthesia, and the pulp damage is small. 3, gingival stimulation is small bonding bridge edge mostly in the gingiva, the gingival health impact is small. 4, low cost bonded bridge repair than the same material of the traditional fixed porcelain bridge cost slightly lower. 5, bonded bridge shedding rate is higher than the traditional fixed bridge: bonded bridge due to the main bonding retention, its retention force than the traditional fixed bridge retention force is small, there is a possibility of shedding or loosening. However, if there is no damage to the abutment tissue and deformation of the restoration after shedding or loosening, it can be re-bonded. Otherwise, it is necessary to re-fabricate the restoration or change to another restoration method. 6, affect the aesthetics: the mandibular posterior teeth do metal wing plate bonding bridge will expose part of the metal affect the aesthetics. Second, the bonded bridge restoration process: 1, preoperative examination, treatment planning, abutment preparation, take the model. 2, bridge trial, colorimetric. 3, Wearing teeth, bonding. Take parallel projection X-rays of abutment teeth. 4.Regular review. Because the bonded bridge may loosen or fall off, and if it loosens for a long time, it may cause decay of abutment teeth and periodontal damage and other problems. Therefore, if you want to do the bonded bridge restoration, you should ensure that you can review regularly after the restoration, and deal with the problems in time. 1. Periodic review: Generally, the restoration is reviewed every six months for the first two years from the date of restoration, and every year after two years, so that the doctor can keep track of the restoration and the abutment teeth, and do the necessary maintenance on the abutment teeth and the restoration. Parallel projection X-rays of the abutment teeth should be taken at the time of the review. If the bonded bridge is found to be loose, fall off, or other abnormalities, please follow up in time to avoid caries of the abutment teeth or other problems; 2. 3, do not chew too hard food: such as gnawing bones, bite open nut shells, etc., because excessive chewing force may cause chipped porcelain phenomenon, need to be restored, and bonded bridge can be better to restore the chewing function of missing teeth, but too heavy a load will cause damage to the bonded bridge, loosening, falling off, and even the abutment teeth loosening, splitting, resulting in tooth extraction and restoration failure.
