\n\t Bridges and dental implants are used to replace missing teeth. With a bridge, only the outer, crown part is restored. An implant is an artificial root made of titanium, which is integrated into the bone tissue and takes over the functions of the natural tooth root. All things being equal, a classic bridge is not able to compete with implants. Although implant placement is a physiologic technology, the bridge prosthetics supported by your own teeth does not lose ground.<\/p>\n

\n A dental bridge is a fixed prosthetic structure consisting of several artificial crowns. It allows you to restore a segment of missing consecutive tooth units from 1 to 3. Two supports are required for attachment, which are your own teeth. That is why bridges are not used when the farthest units are lost (end defect).<\/p>\n
\n\t The classic bridge is a framework in the form of several crowns made of metal or precious alloys, covered with a layer of ceramic or plastic or metal-free – ceramic or zirconium. The two outermost crowns are hollow – they cover the supporting units. In order to tightly fix the prosthetic construction, the supports are depulped and machined beforehand, giving them a cone-shaped form. The bridge is fixed to the teeth with dental cement. It is impossible to remove the structure without damaging it.<\/p>\n
\n\t Many specialists prefer not to tell their patients about the real disadvantages of classical prosthetics. The main one is the inability to stop the processes of bone atrophy under the bridge. When carrying out implantation, not only the crown part is restored, but also the root. The jawbone acquiring the usual load activates the processes of natural regeneration. The bone recession stops and the tissue volume is gradually restored.<\/p>\n

\n\t Implant-supported prosthetics differs from classical prosthetic technology. The method is based on the rehabilitation of the dentition without the involvement of healthy units. Instead of a missing or non-viable tooth, a separate implant – a titanium root imitating a natural tooth – is implanted, on which a prosthetic structure (crown, bridge, full denture) is fixed. Dental implants can be used to restore any number of units – from 1 to all units in a row.<\/p>\n
\n\t Implant and bridge prosthetics have a number of cardinal differences. Each technique is characterized by advantages and disadvantages. The doctor chooses the technology after evaluating all factors.<\/p>\n
\n\t Implants can withstand increased masticatory loads, evenly distributing them on the jaw, due to this they do not collapse in the process of operation. Unlike classic bridges, which require systematic re-cementation, implants are implanted once and for life.<\/p>\n
\n\t In the case of classical bridges, the load is placed on the supporting teeth. This can lead to their gradual destruction and extraction. The size of the prosthesis will grow until there are no supporting units left. Bone atrophy will continue at the site of the defect. Implantation solves this problem.<\/p>\n
\n\t The main disadvantages of implantation include:<\/p>\n
\n\t Placement of a bridge requires the preparation of two supports. It is unfortunate if healthy units have to be traumatized. Due to uneven redistribution of mechanical load, bone atrophy accelerates, the contour of the gum changes, sags. A gap appears between the bridge and the gingiva, where bacterial plaque and food particles accumulate. Not all prosthetic structures are subject to repair and relocation. Teeth under the crowns are subject to secondary caries, which will lead to rapid tissue destruction and increase the length of the defect.<\/p>\n
