Primary Outcome Measures:

To study the short term and long term osseous integration of implant supported restorations on immunocompromised (HIV positive) patients. [ Time Frame: Every 6 months after implant restoration complete ]
To study the short term and long term osseous integration of implant supported restorations on immunocompromised (HIV positive) patients.

Secondary Outcome Measures:

Radiographic examination of implant osseous integration using Cone Beam CT and traditional vertical bitewing radiographs. [ Time Frame: one year after implant restoration ]
Radiographic examination of implant osseous integration using Cone Beam CT and traditional vertical bitewing radiographs.
Histologic examination of bone biopsies from each implant surgical site, at the time of initial placement, and from failing implant sites, including histologic examination of the implant-bone interface. [ Time Frame: at the initial implant placement surgical site ]
Histologic examination of bone biopsies from each implant surgical site, at the time of initial placement, and from failing implant sites, including histologic examination of the implant-bone interface.

control group

Age 19 and older, Non- smoker (quite smoking at least 6 months) Controlled Type II diabetes Controlled hypertension Non bisphosphate user Non- bruxer

HIV positive

HIV (+) patients with the following requirements:

Age 19 and older, Hemoglobin >8g/dl , Absolute neutrophil count >750/mm3, Platelet count>75,000cells/mm3, AST< 5 times the upper limit of normal (ULN), Bilirubin< 2.5 times ULN, Alkaline phosphate < 5 times ULN, Creatinine< 2.5 mg/ml Non- smoker (quite smoking at least 6 months) Controlled Type II diabetes Controlled hypertension Non bisphosphate user Non- bruxer

Detailed Description:

The purpose is to place implants and restore them with crowns in both HIV positive and HIV negative patients then follow patients 3 years period of time, to evaluate how well dental implants perform in HIV-positive patients versus HIV-negative patients.
