Marginal bone changes around platform-switched conical connection implants placed 1 or 2 mm subcrestally: A multicenter crossover randomized controlled trial

AbstractIntroduction:This study analyzes early marginal bone modifications occurring aroundplatform-switched implants with conical connection placed 1 or 2 mm subcrestally.Methods:This crossover randomized controlled trial enrolled partially edentulouspatients needing two implants in either the posterior maxilla or mandible. Eachpatient received two platform-switched implants with conical connection inserted2 mm (Test) and 1 mm (Control) subcrestally. Definitive abutments were immediatelyconnected and, after 4 months of unsubmerged healing, screwed metal-ceramiccrowns were delivered. Radiographs were taken at implant placement (T0), prosthesisdelivery (T1), and after 1 year of prosthetic loading (T2).Results:Fifty-one patients (25 males and 26 females; mean age 61.2 ± 12.1 years)totaling 102 implants were included in the final analysis. Mean peri-implant bonelevel (PBL) reduction from T0 to T2 was not significantly different around Test (0.49± 0.32 mm) and Control implants (0.46 ± 0.35 mm;p=0.66). Multivariate linearregression models highlighted a significant positive correlation between history ofperiodontitis and PBL reduction. At T2, no Test group implant and 6 Control groupimplants exhibited PBL below the implant platform (11.8% of Control groupimplants).Conclusion:No significant differences in peri-implant marginal bone changes weredemonstrated after 1 year of prosthetic loading between platform-switched implantswith conical connection inserted either 1 or 2 mm subcrestally. However, 2 mm sub-crestal placement resulted in deeper implant positioning at T2, with no exposure oftreated implant surface and potential preventive effect against subsequent peri-implant pathology

Discarding IVF embryos: reporting on global practices

Purpose: To provide a global scale report on a representative sample of the clinical embryology community depicting the practice of discarding supernumerary IVF embryos. Methods: A web-based questionnaire titled “Anonymous questionnaire on embryo disposal practices” was designed in order to ensure anonymous participation of practicing clinical embryologists around the world. Results: During a data collection period of 8 months, 703 filled-in questionnaires from 65 countries were acquired. According to the data acquired, the majority of practitioners, dispose of embryos by placing them directly in a trash can strictly dedicated for embryo disposal for both fresh and frozen cycles (39% and 36.7% respectively). Moreover, 66.4% of practitioners discard the embryos separately—case by case—at different time points during the day. Over half of embryologists (54%) wait until day 6 to discard the surplus embryos, while 65.5% do not implement a specially allocated incubator space as a designated waiting area prior to disposal. The majority of 63.1% reported that this is a witnessed procedure. The vast majority of embryologists (93%) do not employ different protocols for different groups of patients. Nonetheless, 17.8% reported the request to perform a ceremony for these embryos. Assessing the embryologists’ perspective, 59.5% of participants stated that the embryology practice would benefit from a universally accepted and practiced protocol. Conclusion(s): This study uniquely provides insight into global embryo disposal practices and trends. Results highlight the divergence between reported practices, while indicating the significance on standardization of practice, with embryologists acknowledging the need for a universally accepted protocol implementation

Implant insertion in a patient with Albers-Schonberg's disease: Case report and literature review

Background The aim of the present report was to present the clinical, radiological and histological outcomes of a case of implant placement in the upper jaw of a patient affected by osteopetrosis. Case report In a 68 years old patient, 2 implants were placed in a portion of bone with areas with high density bone. Histological evaluation confirmed the radiological diagnosis of osteopetrosis. Implants were loaded 8 months after their placement. No complications or adverse reactions were observed after a 24-month follow up. Conclusion Within the limitations of the present report, it can be concluded that a successful implant rehabilitation can be done in patients affected by osteopetrosis. Further studies, on a larger sample size, are needed to confirm this result

Upon surgical management of two different types of pathological fractures caused by hidden cysts

Aim: Pathological fractures of the maxillary bones are quite rare; they occur when a weakening of the bone is generated by unrecognized bone diseases or surgical practices and so the fracture margin results in close proximity to the lesion. In this paper we describe the different surgical management of two maxillary bone\u2019s fractures related to cysts, in order to promote a new surgical approach. Methods: Examining the CT scan of our rst patient, a 54-year-old woman with a history of accidental trauma, not only a zygomatic-maxillary complex (ZMC) fracture was found, but also an intrasinusal cystic lesion (22.5 x 28.8 mm) that had been expanded massively in the anterior and lateral walls. At rst, alterations in cutaneous sensitivity or damage to eyesight were excluded; subsequently oral antibiotic therapy was prescribed and after 4 days a surgical session in GA was planned. During surgery we recornized that the right buccal cortex of the maxilla was deformed by the lesion. After isolation of the right infraorbital nerve, the maxillary fracture was reduced, xing it with a microplate and titanium screws. Necrotic teeth 15 and 16 were extracted (the apexes were included in the lesion) and the cyst was easily enucleated using the bone gap created by the fracture\u2019s margin. Then the anterior maxillary wall was replaced and, in order to overcome bone fragility, a large titanium plate was xed. The procedure ended with reduction and xation of other fractures and intraoral and cutaneous sutures. Further on, a 21-year old patient came to our observation with a traumatic mandibular fracture resulted from a scuf e. The physical examination excluded paresthesia, but showed altered occlusion and mandibular excursions. OPT and CT showed a left paramedian fracture of the mandible and another one near tooth 38; moreover, as occasional nding, a cyst was detected. After 6 days during surgicery under GA, a full thickness ap, from tooth 33 to 43, was raised and a traditional approach was chosen by opening a vestibular bone trap helped by piezoelectric instrument. Within the endosseous cavity only blood and minimal residuals of soft tissue were found. Finally the bone trap was repositioned, the fractures were reduced using miniplates and xing screws and the ap was repositioned and sutured. At the end of the surgery, an intermaxillary xation was applied and maintained for 15 days. Results: Histological examination of the rst case gave a diagnosis of odontogenic cyst. At 13 days after surgical session the facial symmetry and the physiological eye mobility were restored; the surgical wound was on way of consolidation. The histological examination of the fragments found within the bone de ciency that had caused the mandibular fracture con rmed a diagnosis of SBC. The last check (within 21 days) showed: good stability of the applied titanium plates, optimal healing of hard and soft tissues and physiological mandibular movements. Conclusions: Using the same surgical time to enucleate cyst and reduce a pathological fracture has the rationale to improve postoperative morbidity and prognosis. Therefore, if the more traditional approach has its undoubted value, the opportunity to access the cystic lesions by using the gap caused by the fracture line, the way we decided to approach our rst case, should be, in our opinion, taken into serious consideration in similar clinical and surgical situations

Navigating assisted reproduction treatment in the time of COVID-19: concerns and considerations

The COVID-19 pandemic has fueled numerous debates in the field of assisted reproductive technology (ART) as the effect of SARS-CoV-2 on pregnancy and infancy is still considered uncharted territory. Various theses and recommendations on what optimal practice is have emerged, as evidenced by surveys, webinars, and recent publications. ART specialists are faced with dilemmas in light of the lack of concrete scientific evidence required to pave the way towards future safe practice. Meanwhile, infertile couples were similarly left in limbo unable to exercise their reproductive autonomy unlike fertile couples—where achieving a pregnancy via natural conception is a matter of decision. ART treatment being classified as non-essential has only recently re-started, facing new challenges while enabling pregnancy at a time of uncertainty. This article highlights matters of bioethical nature to be considered in the ART world at the time of COVID-19 while presenting an all-inclusive critique of the current status. When pursuing pregnancy through IVF treatment during the pandemic, distancing and caution have the lead role in an effort to defend the health of the intended parents and future children. To promote patient autonomy along with our ethical, moral, and legal duty towards our patients, emphasis should be given on ascertaining shared decision-making, and ensuring that an appropriate all-inclusive informed consent is signed prior to initiating any IVF treatment. © 2020, Springer Science+Business Media, LLC, part of Springer Nature
