Our study found a slightly higher failure rate of 10 % in patients with AIDS, compared to widely accepted failure rates in healthy patients at 5–7 %. A cohort sample size of 33 may be considered small for statistical power; however, the results from this study could lead to larger future prospective cohort studies with additional funding to recruit a larger cohort and comparison groups. The ad...

Regarding dental procedures, a retrospective cross-sectional study of 101 HIV patients was done from 2003 to 2005. Complication rate was found to be 2.2 % overall and 4.8 % after invasive dental procedures. No relationship was found between complications and immunological values [14]. Another study examining healing response after surgical crown lengthening in 21 patients with HIV was analyzed, ...

Discussion : Prospective cohort study of dental im...

Generally speaking, the use of antibiotics in dental implantology has been controversial. Amongst the reasons for early (preloading) implant failure are bacterial contamination, systemic disease, chemotherapy, overheating of bone, poor recipient site bone quality, and poor bone to implant contact upon surgery. After the prosthetic phase of the implant restoration, loading forces exceeding the bone...

Since the AIDS epidemic reared its head in the 1980s, the nature of this disease has quickly evolved from a devastatingly debilitating disease to one of chronicity. These patients are requesting for and are entitled to the optimal restorative treatment plans, many of which include dental endosteal implants. Several authors have delved into the realm of implantology in the HIV-positive patient, but...

Descriptive statistics are presented in Table 1. Sixteen (n = 16) patients met our inclusion criteria and were included in our study. The sample included 12 males and 4 females. The mean age at enrollment was 36.2 years (sd 8.83 years). The mean CD4 count at the time of placement was 141.25 (sd 35.5). A total of 33 implants were placed in the 16 patients, including 5 mandibular implants and...

Standard descriptive statistics were used to examine the distribution of key variables (age, gender, CD4 count at baseline and follow-up, and failure rate) in the sample. Due to the small sample size in this study (n = 16), the relationship of CD4 count and failure will be examined graphically and cases which failed are discussed individually in the “Results” section. A bar chart is presen...

Our study is a prospective study looking at the failure rates in root-formed implants in AIDS patients at 5 years post-surgical placement of the implant fixtures. Patients recruited for the study had to meet inclusion criteria which included diagnosis of AIDS measured by a pre-operative cluster of differentiation 4 (CD4)

The Joint United Nations Programme on HIV/AIDS estimates that 36.9 million (34.3–41.4 million) people are living with human immunodeficiency virus (HIV) infection [1].

Oral health care of patients with acquired immune deficiency syndrome (AIDS) due to human immunodeficiency virus (HIV) is a growing area of concern, taking into consideration the increased life expectancy of patients resulting from antiretroviral therapy. There is insufficient literature regarding the impact of dental implants in AIDS patients. This study investigated the long-term clinical outcom...

Nevertheless, the amount of bone generated with BC or BC + EMD herein was adequate to support successful implant placement and osseointegration of implants.

The present study compared the histological and histomorphometrical outcome of healing after maxillary sinus floor augmentation with BC with or without EMD, based on human biopsies.

Nevertheless, the amount of bone generated after maxillary sinus floor augmentation ...

All ten patients showed uneventful healing after the sinus floor augmentation procedure as well as after dental implant placement, with no overt postoperative inflammation or infection.

Reconstruction of the edentulous and severely atrophied posterior maxilla is often performed by means of maxillary sinus floor augmentation in combination with dental implants [1, 2]. Various bone graft materials are typically used for enhancing bone formation within the sinus cavity; autogenous bone (AB) is considered as the gold standard due to its osteogenic, osteoinductive, and osteoconductive...

It is still unclear whether enamel matrix proteins (EMD) as adjunct to bone grafting enhance bone healing. This study compared histomorphometrically maxillary sinus floor augmentation (MSFA) with β-TCP/HA in combination with or without EMD in humans. In ten systemically healthy patients needing bilateral MSFA, one side was randomly treated using β-TCP/HA mixed with EMD (BC + EMD) and the ot...

Discussion Since the AIDS epidemic reared its head in the 1980s, the nature of this disease has quickly evolved from a devastatingly debilitating disease to one of chronicity. These patients are requesting for and are entitled to the optimal restorative treatment plans, many of which include dental endosteal implants. Several authors have delved into the realm of implantology in the HIV-pos...

Results Descriptive statistics are presented in Table 1. Sixteen (n = 16) patients met our inclusion criteria and were included in our study. The sample included 12 males and 4 females. The mean age at enrollment was 36.2 years (sd 8.83 years). The mean CD4 count at the time of placement was 141.25 (sd 35.5). A total of 33 implants were placed in the 16 patients, including 5 mandibular imp...

Methods Our study is a prospective study looking at the failure rates in root-formed implants in AIDS patients at 5 years post-surgical placement of the implant fixtures. Patients recruited for the study had to meet inclusion criteria which included diagnosis of AIDS measured by a pre-operative cluster of differentiation 4 (CD4)

Background The Joint United Nations Programme on HIV/AIDS estimates that 36.9 million (34.3–41.4 million) people are living with human immunodeficiency virus (HIV) infection. In America, the Centers for Disease Control and Prevention (CDC) estimated that 1.2 million people aged 13 or older were HIV infected by the end of 2012 and the cumulative population of persons surviving for more than 36...

Dental implant success rate in patients with AIDS

Abstract Background Oral health care of patients with acquired immune deficiency syndrome (AIDS) due to human immunodeficiency virus (HIV) is a growing area of concern, taking into consideration the increased life expectancy of patients resulting from antiretroviral therapy. There is insufficient literature regarding the impact of dental implants in AIDS patients. This study in...
