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 28 maxillary implants. The average time to uncovering was 151 days (sd 25 days) for all implants that did not fail. Tables 2 and 3 present the distribution of implant site and implant size, respectively. A total of three implants, in two patients, failed prior to uncovering. This is shown graphically in Fig. 1. In the patient with one failure, the implant failed at post-op day 12 secondary to infection. In the patient with two failures, two failed secondary to non-bony union, at post-op days 31 and 46. Two of the three failures were maxillary implants in the anterior arch, and the third was in the mandibular posterior arch. A Kaplan-Meier survival function is shown in Fig. 2.
