If you have a missing tooth, a bridge can be used to fill the missing space and close this gap. A dental bridge is a false tooth (called a pontic) that is held in place by abutment teeth on either side. There are four different types of brides: traditional bridge, cantilever bridge, Maryland bridge, and implant-supported bridge.
A traditional dental bridge consists of a false tooth or teeth being held in place by dental crowns that have been cemented onto each of the abutment teeth. A traditional bridge is the most popular type of dental bridge and can be used when you have natural teeth on both sides of the gap created by your missing tooth.
Although similar to a traditional bridge, the pontic in a cantilever dental bridge is held in place by a dental crown that is cemented to only one abutment tooth. For a cantilever bridge, you only need one natural tooth next to the missing tooth gap.
Similar to a traditional bridge, Maryland dental bridges employ two natural abutment teeth, one on each side of the gap. However, while a traditional bridge uses dental crowns on the abutment teeth, a Maryland bridge uses a framework of either metal or porcelain that is bonded onto the backs of the abutment teeth.
Like a traditional bridge, a Maryland bridge can only be used when you have a natural tooth on each side of the gap caused by the missing tooth or teeth.
As the name implies, implant-supported bridges use dental implants as opposed to crowns or frameworks. Typically, one implant is surgically placed for every missing tooth, and these implants hold the bridge in position. If one implant for each missing tooth isn’t possible, the bridge may have a pontic suspended between two implant-supported crowns.
Ikiwa una meno yaliyopotea, daraja linaweza kutumiwa kujaza nafasi iliyopotea na kufunga pengo hili. Daraja la meno ni jino bandia (linaloitwa pontic) linaloshikiliwa mahali pake na meno ya nguzo upande wowote. Kuna aina nne tofauti za mabibi-arusi: daraja la kitamaduni, daraja la cantilever, daraja la Maryland, na daraja linaloungwa mkono na upandikizaji. Daraja la meno la kawaida lina meno bandia au meno yanayohifadhiwa mahali pake na taji la meno ambalo limeunganishwa kwenye kila jino la msingi. Daraja la kawaida ni aina maarufu zaidi ya daraja la meno na inaweza kutumika wakati una meno ya asili pande zote mbili za pengo lililoundwa na jino lako linalokosekana. Ingawa ni sawa na daraja la jadi, pontus katika daraja la meno la cantilever hufanyika mahali pake na taji la meno ambalo limeunganishwa na jino moja tu la abutment. Kwa ajili ya daraja cantilever, unahitaji tu jino moja ya asili karibu na pengo meno kukosa. Sawa na daraja la kitamaduni, madaraja ya meno ya Maryland hutumia meno mawili ya asili, moja upande wa kila upande wa pengo. Hata hivyo, wakati daraja la jadi hutumia mataji ya meno kwenye meno ya abutment, daraja la Maryland hutumia muundo wa chuma au kauri ambayo imeunganishwa kwenye nyuma ya meno ya abutment. Kama vile daraja la kawaida, daraja la Maryland linaweza kutumika tu wakati una meno ya asili upande wa kila mmoja wa pengo linalosababishwa na meno yanayopotea. Kama jina linavyodokeza, madaraja yanayotegemezwa na implanti hutumia implanti za meno badala ya taji au muundo. Kwa kawaida, implanti moja huwekwa kwa upasuaji kwa kila jino linalokosekana, na implanti hizo huweka daraja hilo mahali pake. Ikiwa implant moja kwa kila jino linalokosekana haiwezekani, daraja linaweza kuwa na pontic iliyofungwa kati ya taji mbili zinazoungwa mkono na implant.
