Txhua txhua hnub, ntau tus neeg nyob ib ncig ntawm lub ntiaj teb no undergo kev cog hniav. Cov hniav cog yog me me inserts, uas yog implanted rau hauv lub puab tsaig, kom ruaj ntseg prosthetic hniav. Lawv yuav tsum tau manufactured los ntawm ib tug ntau ntawm biocompatible cov ntaub ntawv xws li ntshiab titanium, stainless hlau thiab zirconia. Yog hais tias uas ploj lawm cov hniav yog tiv thaiv koj los ntawm enjoying lub neej mus rau lub fullest, Tom qab ntawd kev cog hniav yuav yog qhov kev xaiv zoo rau koj.

Tib txoj kev uas yuav nrhiav tau kom paub tseeb tias koj puas tsim nyog rau kev cog hniav yog sab laj nrog ib tug kws kho hniav uas muaj kev paub zoo uas tuaj yeem ua qhov kev ntsuam xyuas kom zoo, Ua ntej muab cov lus teb tseeb rau koj. Qee hom kev cog hniav uas feem ntau muaj niaj hnub no yog endosteal cog, Subperiosteal implants thiab transosseous hniav implants. Of these, transosseous dental implants are nowadays the most rarely used.

Transosseous Implants

Being a type of endosseous implant, transosseous dental implants require to be surgically inserted into the jawbone. They were originally designed as a secure implant system for patients who did not possess any teeth in their lower jaw, coupled with insufficient bone quantity. Most dental implantologists now recommend transosseous dental implants only in rare circumstances, preferring to use root or plate implants with bone grafts, in cases where patients do not have enough bone in their jaw.

Shaped like a ‘U’, transosseous teeth implants consist of a plate, with two long screw posts on both ends. During the surgical process, the bottom plate is pressed to the lower part of the chinbone, and holes are drilled to enable the two posts to penetrate the chin bone, and emerge through the jaw ridge, inside the mouth. Nuts and pressure plates are then used to secure the screw posts to their required positions.

The teeth implants are then left to heal for a few months, with the exact time required depending upon the healing ability of the patient. During the healing period, bone should grow so closely around the dental implants that it effectively fuses with it. After the dental implantologist determines that the bone has sufficiently healed, prosthetic teeth made of porcelain or acrylic, are attached to the screw posts, txhawm rau ua kom tiav qhov kev kho hniav.

 

Clinical Summary & Recommendation

A series of screws go through the bottom of the front part of the jaw. Cov ntsia hlau txuas rau ib lub phaj nyob rau sab saum toj ntawm lub puab tsaig pob txha, thiab ob qho txuas ntxiv protrude saum cov pos hniav rau kev ruaj khov ntawm ib qho prosthesis.
Kev Phais Zoo:	Muab kev ruaj khov zoo los ntawm bicortical stabilization
Kev phais tsis zoo	Tsuas yog qhia rau lub mandible anterior. Yuav tsum tau mus kom ze ntawm qhov ncauj ntxiv (Ib qho kev txiav tawm yog ua hauv qab lub puab tsaig).
Prosthetic Advantages	Tsis muaj
Prosthetic Disadvantages	Prosthetic abutments yog tsawg heev thiab abutments tej zaum yuav tsis nyob rau hauv txoj hauj lwm uas peb yuav xav tau rau qhov zoo tagnrho cov hniav. Tsuas yog pab tau rau mandibular overdentures.
Economics	Cov kev cog hniav no yog ib qho nyuaj thiab kim rau manufacture. Kuv ntseeg hais tias muaj tsuas yog ib qhov chaw rau cov kev cog hniav no. Lawv kim heev.
Cov lus pom zoo	Qhov no yog feem ntau ib qeb qis dua. Tsis pom zoo!
