Implants with a roughened neck surface and microthreads are more resistant to MBL during the first phases of healing, as compared with implants with a polished neck.

This is the largest myiasis case series in ill returning travelers. Myiasis is not a rare dermatologic complaint with most Israeli cases imported from Latin America and specifically the Madidi National Park in Bolivia. Treatment is based on full extraction of the larva after which no antibiotic treatment is needed. Myiasis is a preventable disease and travelers should be informed of the different preventive measures according to their travel destination.

Background Peri‐implantitis is a challenging condition to manage and is frequently treated using non‐surgical debridement. The local delivery of antimicrobial agents has demonstrated benefit in mild to moderate cases of peri‐implantitis. This study compared the safety and efficacy of chlorhexidine gluconate 2.5 mg chip (CHX chips) as an adjunctive treatment to subgingival debridement in patients afflicted with peri‐implantitis. Methods A multicenter, randomized, single‐blind, two‐arm, parallel Phase‐3 study was conducted. Peri‐implantitis patients with implant pocket depths (IPD) of 5‐8 mm underwent subgingival implant surface debridement followed by repeated bi‐weekly supragingival plaque removal and chlorhexidine chips application (ChxC group) for 12 weeks, or similar therapy but without application of ChxC (control group). All patients were followed for 24 weeks. Plaque and gingival indices were measured at every visit whereas IPD, recession, and bleeding on probing were assessed at 8, 12, 16, 24 week. Results A total of 290 patients were included: 146 in the ChxC group and 144 in the control. At 24 weeks, a significant reduction in IPD (P = 0.01) was measured in the ChxC group (1.76 ± 1.13 mm) compared with the control group (1.54 ± 1.13 mm). IPD reduction of ≥2 mm was found in 59% and 47.2% of the implants in the ChxC and control groups, respectively (P = 0.03). Changes in gingival recession (0.29 ± 0.68 mm versus 0.15 ± 0.55 mm, P = 0.015) and relative attachment gain (1.47 ± 1.32 mm and 1.39 ± 1.27 mm, P = 0.0017) were significantly larger in the ChxC group. Patients in the ChxC group that were < 65 years exhibited significantly better responses (P < 0.02); likewise, non‐smokers had similarly better response (P < 0.02). Both protocols were well tolerated, and no severe treatment‐related adverse events were recorded throughout the study. Conclusions Patients with peri‐implantitis that were treated with an intensive treatment protocol of bi‐weekly supragingival plaque removal and local application of chlorhexidine chips had greater mean IPD reduction and greater percentile of sites with IPD reduction of ≥2 mm as compared with bi‐weekly supra‐gingival plaque removal.

Objective To compare the early changes in implant stability of implants with different neck design during the first 3 months of healing in the posterior maxilla. Materials and methods Patients were randomized to receive triangular neck implant (test), or round neck implant (control). Resonance frequency analysis (ISQ) measurements were obtained at surgery and at 2, 4, 7, 14, 21, 28, 45, 60, and 90 days following implant placement. Non‐parametric statistic was used for data analysis. Results Thirty‐two patients were included (17 test and 15 controls). Initial ISQ values of the test implants were high (mean: 68.4, SD = 8.4) and increased over time (mean: 74.4, SD = 6.0). Control implants presented a statistically significant higher initial ISQ value at implant placement (mean: 76.9, SD = 8.7), which was maintained over the healing period (mean: 77.6, SD = 3.6) with no significant changes between time intervals. After 6 weeks of healing, both implants displayed comparable ISQ values with no differences between the groups. All implants exhibited a decrease in stability on days 2 and 21 post‐placement. All roundneck implants used, and 82% of the triangularneck implants showed initial ISQ values above the suggested threshold for immediate loading (>60). Conclusions Implant neck design plays a role in implant primary stability in the posterior maxilla. Both implants show high primary stability, with significantly higher values for the round neck. However, these differences disappeared after 6 weeks of healing. While primary implant stability is partially governed by implant neck design, the role of this result is negligible for the achievement of secondary stability.

The study provides the microbial profile of commonly used sutures and may assist in suture selection during clinical procedures.
