The purpose of this non-random retrospective cohort study was to evaluate the impact of prophylactic antibiotic on early outcomes including postoperative pain, swelling, bleeding and cyanosis in patients undergoing dental implant placement before prosthetic loading. Seventy-five patients (45 males, 30 females) whose dental implant placement were completed, included to the study. Patients used prophylactic antibiotics were defined as the experimental group and those who did not, were defined as the control group. The experimental group received 2 g amoxicillin + clavulanic acid 1 h preoperatively and 1 g amoxicillin + clavulanic acid twice a day for 5 days postoperatively while the control group had received no prophylactic antibiotic therapy perioperatively. Data on pain, swelling, bleeding, cyanosis, flap dehiscence, suppuration and implant failure were analyzed on postoperative days 2, 7, and 14 and week 12. No statistically significant difference was detected between the two groups with regard to pain and swelling on postoperative days 2, 7, and 14 and week 12 ( p >0.05), while the severity of pain and swelling were greater on day 2 compared to day 7 and 14 and week 12 in both groups ( p =0.001 and p <0.05, respectively). Similarly, no significant difference was found between the two groups with regard to postoperative bleeding and cyanosis. Although flap dehiscence was more severe on day 7 in the experimental group, no significant difference was found between the two groups with regard to the percentage of flap dehiscence assessed at other time points. Within limitations of the study, it has been demonstrated that antibiotic use has no effect on implant failure rates in dental implant surgery with a limited number of implants. We conclude that perioperative antibiotic use may not be required in straightforward implant placement procedures. Further randomized control clinical studies with higher numbers of patients and implants are needed to substantiate our findings.

SummaryIn 12 dogs with hip dysplasia, 20 triple pelvic osteotomies (eight bilateral and four unilateral) were performed. Screw loosening, occurring in six of 12 dogs (seven of 20 osteotomies), was the most common complication after surgery. Implants loosened from the cranial ilium in six hemipelvises (30%) and from both fragments in one hemipelvis, two to six weeks (mean — three) after the operation. Medial acetabular displace-ment caused pelvic narrowing (6 to 9%, mean = 8%) in three of four dogs. Medial ischial displacement decreased pelvic diameter (11 to 21%, mean = 17%) in four of seven osteotomies. All of the dogs with implant failure were treated conservatively with cage rest and in two cases Ehmer slings were used. Although none were lame, gait abnormalities were evident in three of seven dogs on follow-up examinations four to 12 months (mean = six) later.Screw loosening, occurring in seven of 20 hemipelvises, was the most common postoperative complication associated with triple pelvic osteotomy. Fixation failures were managed conservatively. Despite decreased pelvic diameter in four of seven animals, none were lame or showed signs of pelvic obstruction at follow-up examinations four to 12 months later.

Maxillary sinus floor augmentation (MSFA) is widely used and considered a predictable procedure for implant placement. However, the influence of MSFA on implant survival and marginal bone loss (MBL) is still inconclusive. The purpose of this retrospective observational study is to evaluate the long-term genuine influence of MSFA on the survival and MBL of implants by comparing those with and without MSFA only in maxillary molars within the same patients. Thirty-eight patients (28 male and 10 female), with a total of 119 implants, received implants with and without MSFA, and were followed up for 5.8 to 22 years. Patient- and implant-related factors were assessed with a frailty model for implant survival and with generalized estimation equations (GEE) for MBL around the implant. No variables showed a statistical significance for implant failure in the frailty model. In GEE analysis for MBL, MSFA did not show any statistical significance. In conclusion, MSFA demonstrated no significant influence on implant failure and MBL in posterior maxilla in this study.
