DEFINITION DEFINATION- A dental implant is prosthesis

placed in bone(root) allowed to osseintergrate to support an artificial tooth(crown)

cylindricalthreaded

HOW IT WORKS Take a titanium post and inserting it deep

within the jaw bone.  The bone accepts and osseointegrates with

the titanium rod, merging into the bone in a similar manner as to how a natural tooth root is enclosed within the bone.

Once the bone has completely fused with the titanium, an artificial tooth can be secured into the rod

MEDICAL HX ORAL EXAM. IMAGING ; Imaging is done before and after

dental implants placement to assess bone characterstics at the site of insertion. High resolution CT imaging .Bone type ,Bone thickness, Density

TEENAGERS

PATIENT SELECTION

PROCEDUREo Surgical procedure o Flap surgery:- insert titanium post in the bone (swelling, bruising, pain, and minor bleeding around the gum area is expected) oRestorative procedureomaintenance  

IMPLANT DESIGN (OVERDENTURE)

CHALLENGES• Injuries to the surrounding teeth• Nerve damage• Pain, numbness, or tingling feeling in the

gums, mouth, chin, or neck area• Sinus problems, especially if the implants

are being placed in the upper jaw.• Infection at or around the implantation area

Advantageso Feels and chews like real teetho Doesn’t alter neighbouring teetho Completely secure after healingo No creams or glues are neededo Better for long-term oral healtho Looks identical to real teetho Can be used for one tooth or severalo Easy to care o Improveo High success rate of around 95%o bone stabilization & maintenance

Disadvantages

o Expensive

o Patient selection

risk of screw loosening

risk of fixture failure

length of treatment time

need for multiple surgeries

challenging esthetics

CONCLUSION

2-trained periodontists in implantology

3-trained restorative dentists in implantology

Maxillofascial surgeonsNeed to train dental technologists Need to invest in the equipments

and materials for these procedures
