- BackgroundBiomaterials are commonly used to augment the maxillary sinus floor prior to or in conjunction with dental implant installation. Recently, porous titanium granules (PTGs) have been used in oral implant surgery to stabilize implants and function as an osteoconductive matrix. PurposeTo evaluate if PTGs can be safely used in a larger population of patients, treated by different surgeons, when sinus floor augmentation was required in conjunction with implant installation. The primary endpoint was 12-month survival rate of the dental implants. Biopsies for histology were taken from the augmented area. Materials and MethodsAt five centers, 40 subjects with uni or bilateral posterior edentulism and atrophy of the posterior maxilla (3-6mm) were enrolled. In a single-stage procedure, PTG and one to three dental implants were installed in each quadrant. In total, 70 implants were included in the study. ResultsOne immobile implant was removed. The mean marginal bone loss was 0.5mm and 0.8mm, on the mesial and distal side, respectively. Histologically, all biopsies demonstrated bone ingrowth. ConclusionsThe results suggest that PTG can be safely and effectively used as augmentation material in the sinus floor when used with dental implants in a one-stage procedure.

- OBJECTIVE: To evaluate the onset of analgesic effect for a new formulation of ibuprofen sodium dihydrate versus conventional ibuprofen (ibuprofen acid). MATERIALS AND METHODS: In this randomized, double-blind, double-dummy, crossover trial, patients requiring surgical removal of two impacted or partially impacted mandibular third molars received: ibuprofen sodium dihydrate 400 mg plus conventional ibuprofen placebo (Group 1); or conventional ibuprofen 400 mg plus ibuprofen sodium dihydrate placebo (Group 2) following the first surgery. Patients were then crossed over to the alternative treatment. RESULTS: 72 patients were enrolled in Group 1 and 72 patients in Group 2. Ibuprofen sodium dihydrate produced faster initial pain relief than conventional ibuprofen as assessed by time to first pain relief (24.6 vs. 30.5 minutes; p = 0.004), and patient-assessed pain relief at 15 minutes ("some" to "complete" pain relief: 43% vs. 29%; p < 0.001) and 30 minutes (82% vs. 63%; p < 0.001) and pain intensity at 30 minutes (p < 0.001). Substantial pain relief with ibuprofen sodium dihydrate was twice that of conventional ibuprofen at 30 minutes (11% vs. 5%; not significant); 29% and 33% of patients did not reach substantial pain relief at 120 minutes. There were no adverse events leading to treatment discontinuation and only two serious adverse events (oral abscess and facial paresis with conventional ibuprofen) considered unrelated to treatment. CONCLUSIONS: Ibuprofen sodium dihydrate was as effective as conventional ibuprofen, but had a faster onset of initial pain relief and significantly reduced pain intensity within the first 30 minutes after administration, providing rapid clinically meaningful pain relief for patients.
