The success of endosseous implants in human immunodeficiency virus-positive patients receiving antiretroviral therapy: a pilot study.

Background: In a pilot study, the authors aimed to determine the success rate of dental implants placed in patients who were positive for human immunodeficiency virus (HIV) and were receiving different regimens of highly active anti-retroviral therapy (HAART). They considered patients' levels of cluster of differentiation (CD) 4(+) cells and viral load, and they attempted to verify whether patients with baseline biochemical signs of bone mineral density loss could experience osseointegration impairment.

Materials And Methods: One of the authors, a dentist, placed dental implants in the posterior mandibles of 40 volunteers, divided into three groups: one composed of HIV-positive patients receiving protease inhibitor (PI)-based HAART; a second composed of HIV-positive patients receiving nonnucleoside reverse transcriptase inhibitor-based HAART (without PI); and a control group composed of HIV-negative participants.

Recessive dystrophic epidermolysis bullosa--oral rehabilitation using stereolithography and immediate endosseous implants.

Dental management of patients with epi-dermolysis bullosa (EB) is challenging because of the severe soft tissue lesions associated with this disease. A case history is presented where two immediate endosseous implants were placed in the mandible of a patient with recessive dystrophic EB using computer-aided technology to plan the surgery and prosthetic rehabilitation. After a 24-month follow-up, the prosthesis was stable with healthy asymptomatic soft tissue around the implants.
