Both graft materials are suitable for sinus floor augmentation, with the allograft material being more osteoconductive.

Insertion of implants with a high torque following an under-drilling protocol, commonly used for immediate loading, may reduce crestal bone-to-implant contact at early healing stages.

Background: All-on-four protocols with tilted implants in the maxilla are used to rehabilitate the terminal dentition of the severe generalized periodontitis patients. Data on long-term biological complications are scarce. Methods: Eighty-four axial and forty-six tilted immediate implants have been placed in the extraction sockets of 23 patients according to a four–six implants protocol combined with ridge augmentation. Within 72 h, a provisional prosthesis was cemented to the implants; after 6 months, a cemented ceramic–metallic prosthesis was delivered. The patients were followed for up to 5 years. Results: The 5-year survival rate of the straight and tilted implants was 100% and 97.8, and the prosthetic one was 100%. Marginal bone loss (MBL) of the straight implants was 0.42 ± 0.67 and 0.59 ±1.01 mm on the mesial and distal sides; for the tilted, it was 0.37 ± 0.68 and 0.34 ±0.62 mm, and the differences were not statistically significant. Implant position, smoking, keratinized mucosal width, and cantilever did not affect MBL. Peri-implant mucositis involved 29.4% and 22.2% of the straight and tilted implants, respectively; peri-implantitis involved 5.8% and 4.4% of the straight and tilted implants, respectively, without statistical significance. Conclusions: This immediate loading protocol’s 5-year survival and success rates were high. No difference between the straight and tilted implants was found regarding survival, success rates, and MBL.

ObjectiveTo evaluate cognitive flexibility and labor and delivery outcomes.MethodsA prospective study was conducted of nulliparas with singleton term pregnancy, admitted for labor to a tertiary referral center from 1 January to 31 July, 2017. After epidural anesthesia, parturients completed the validated Psychological Flexibility Questionnaire (20 questions that evaluate a person's level of cognitive flexibility) before delivery. They were asked to grade (from 1 to 10) their hope for vaginal delivery (Hope score). Within 2 hours after delivery, they graded (1–10) the similarity between their delivery and their expectations (Expectation score). Outcomes of the flexible versus less flexible group were compared.ResultsAmong the flexible (n=120) versus less flexible (n=40) group, vaginal delivery was more common (74.2% vs 20.8%) than vacuum extraction (20.8% vs 35%) or cesarean delivery (5% vs 12.5%) (P=0.031). High Expectation score and delivery without grade III–IV perineal tear (P=0.032) were correlated. Groups were similar regarding Expectation (P=0.163) and Hope scores (P=0.591). The mode of delivery of parturients was not correlated with their mothers’ (P=0.836) or sisters’ (P=0.758).ConclusionHigh cognitive flexibility increases the likelihood of vaginal delivery. These findings support the mind–body correlation. Maternal cognitive perceptions can influence labor and delivery and should be considered when counseling patients during labor.
