Aim The fractured bar is a common prosthetic complication that deteriorates the patient’s experience and prosthesis functionality; therefore, we aim to determine risk factors, prevalence, and incidence of bar fracture. Methods We will conduct a systematic review using the guidelines of Cochrane’s Handbook and Joanna Briggs Institute’s (JBI) Manual and will adhere to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A three-step search strategy will be conducted to retrieve interventional and observational studies from biomedical bibliographic databases as well as grey literature. Two authors will assess the retrieved studies according to the predefined eligibility criteria. Data collection will be conducted using Extraction Forms. Risk of bias of included interventional studies will be assessed using the Risk of Bias 2 tool, while observational studies will be evaluated by ROBINS-E. Studies findings will be qualitatively and quantitively synthesized using JBI SUMARI. Results The results of this systematic review will be presented to clinicians and researchers in speciality conferences and a peer-reviewed journal. Conclusion This review is the first to identify the clinical and biological risk factors of bar fracture and to evaluate its prevalence and incidence rates; aiming to provide evidence-based recommendations for treatment planning and maintenance of implant-retained overdenture using bar-clip attachment system.

Aim Periodontal diseases are characterized by the presence of bleeding, inflammation, sensitivity, discomfort, mobility and tooth loss. Plenty of studies supported the assumption that vitamin D deficiency might be a risk factor for periodontal diseases. Our hypothesis aimed to investigate if there is a true association between serum vitamin D level and the presence of periodontal disease. Materials and methods Using a cross-sectional study design, a total of 200 participants, 100 periodontitis and 100 non-periodontitis patients, were recruited during the routine examination and enrolled to 2 comparative groups. Results Serum vitamin D levels of periodontitis patients (11.607±7.58 ng/ml) compared to non-periodontitis patients (11.756±5.608 ng/ml) presented non statistically significant differences (p-value = 0.878). Most of the population (97%) in both groups represented significantly lower serum vitamin D levels. Serum vitamin D levels showed inverse correlation with gender (r= - 0.39) as well as age (r= - 0.09), linear correlation with systemic conditions (r= 0.04) and no correlation with periodontal conditions (r= 0.00). Conclusion The serum vitamin D deficiency is not a risk factor for periodontitis and their relationship is spurious.

Aim The aim of this study was to evaluate the thermal variations during implant osteotomy with three different implant systems at different drilling speeds in the bovine bone. Also, we aimed to explore the period over 47°C during drilling with each drill of each implant system. Materials and methods Using bovine ribs, 3 implant systems were compared: Implantium® (Dentium, Seoul, Korea), Straumann® (Institut Straumann AG, Basel, Switzerland), and Anyridge® (Anyridge, Seoul, Korea). With increasing diameter drills (Implantium (4 drills); Straumann (4 drills); Anyridge (5 drills)) at three drilling speeds (150, 250, and 400 rpm) implant bed preparations were performed with a conventional approach. Maximum heat generated and the duration of the generated heat over 47°C in each drill of each implant system at different drilling speeds were measured, and results were compared. Results Significant increase in temperature was observed for the majority of the drills at 250 rpm (except D-I2, S-4.2, M-2) and 400 rpm (except M-2) when compared to the 150 rpm (p<0.05). However, between 250 and 400 rpm temperature variations did not follow a uniform trend and showed differences based on the drill used. Maximum generated heat observed in D-I2 (400rpm) as 59.37°C for Implantium system, in S-3.5 (250 rpm) as 58.71°C for Straumann system, in M-2.8 (400rpm) as 75.67°C Anyridge system. For all measurements Implantium and Strauman systems exhibit lower variations in temperature when compared to the Anyridge system. The period over critical threshold also below the limit of 1 minute for all measurements. The maximum duration of over 47°C was observed for the drill M-2.8 (400rpm) as 15.63 seconds. Conclusion It can be concluded based on the results of the study that when considering the temperature increase and the time spent for preparation of implant site over the critical threshold by the evaluated systems at different speeds without irrigation was in safe limit clinically. Further in vitro and in vivo studies by considering more parameters required to be conducted to determine the optimum drilling parameters for each implant system in clinical practice.

Aims: To assess the effect of history of conventional denture use, number of implants, age, gender, and time passed since delivery (1 and 3 months) on satisfaction of patients with mandibular implant-supported overdentures. Materials and Methods: This prospective study was conducted on 54 eligible edentulous patients (48-74 years, 30 males and 24 females). After obtaining written informed consent and ethical approval, the patients filled out a questionnaire regarding their satisfaction level with the overdenture. Data were analyzed by the generalized estimating equation (GEE) model at 5% level of significance. Results: History of denture use (P=0.232) and number of implants (P=0.609) had no significant effect on the overall satisfaction of patients. The overall satisfaction was not significantly different between males and females (P=0.415). The effect of time passed since delivery and age on satisfaction level was significant, such that the overall percentage of satisfaction was higher at 3 months after delivery (P<0.001) and in older individuals (P=0.040). Conclusion: The satisfaction level of patients with mandibular implant-supported overdentures depended on the time passed since delivery and age of patients; number of implants (2 or 3) and history of denture use had no significant effect on patient satisfaction with the overdenture.

Aims Maxillary sinus lift is a surgical procedure suitable to restore vertical deficiencies of the posterior maxilla and can be executed either with a lateral or with a crestal approach. One of the most important aspects of a bone regeneration is the stability of the graft. The aim of this study is to introduce a new grafting technique for sinus lift with a lateral approach, which is called Sinus Pack Technique. Methods Four patients with severe vertical atrophy of the alveolar bone in the posterior maxilla who needed unilateral dental implant rehabilitation of the edentulous maxillary region were treated according to the Sinus Pack technique- After 6 months a Computed Tomography scan was taken to assess the obtained bone volumes, implants were placed, and a bone sample was obtained with a 4mm trephine bur. Results Three males and one female (age range 36-75 years) were treated ; no intra- and post-operative complications were recorded. According to the measurements performed on the CT scan before surgery and six months after surgery we found an average vertical gain of 6.95mm. According to the histological and histomorphometric analysis the membrane was completely resorbed, new bone had formed and only a slight percentage of bone-filling granules was still present. Conclusion The Sinus Pack technique has the advantage of being a minimally invasive and safe surgery procedure, with results similar to other sinus lift techniques. More reports are needed to confirm the lower hypothesized complication rate and its efficacy.

Aim BiodentineTM is a calcium-silicate based material that has been studied in recent years for a wide range of clinical applications in both Endodontics (pulp capping, pulpotomy, apexification, retrograde root end filling, repairing of root perforations and resorptions) and in Restorative Dentistry as a dentin substitute. The aim of this study was to review the physical-mechanical properties (porosity, setting time, compressive strength, bond strength/push-out bond strength, sealing ability, marginal adaptation, radiopacity, solubility, color stability) and biological properties (antimicrobial activity, biocompatibility, bioactivity) of BiodentineTM (BD). Materials and methods BD has been analysed in its various physico-chemical aspects and mechanical and biological properties. Results Regarding biocompatibility, bioactivity, antibacterial properties, versatility, stability, sealing properties, compressive and flexural strength, BD fulfils the requirements. Its relatively easy handling, low cost and faster setting are the major advantages of this material when compared to previous calcium silicate cements. Conclusion Clinical studies of long term efficiency and high evidence are still lacking. BD has great potential to revolutionise the management in Restorative Dentistry and Endodontics, but also in Paediatric Dentistry, both for primary and permanent dentition.

Aim The aim of this work is to review the applications of LMHFV in improving bone density around implants and teeth. Results Low magnitude high frequency vibration (LMHFV) has been actively used in orthopedics to improve bone density, osseous healing via stimulation of osteogenic cells, release of growth factors and stimulation of angiogenesis. Those concepts have been carried over to dental treatment. A common clinical challenge in dental practice relates to bone loss associated with periodontal disease, tooth loss or other causes as well as treating tooth mobility and peri-implantitis. Conclusion LMHFV provides similar positive results as reported in orthopedics, to improve osteo-stimulatory affects improving bone quality and density around both natural teeth and dental implants.

Aim Eosinophilic granulomatosis with polyangiitis (EGPA, also known as Churg-Strauss Syndrome) belongs to the group of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) together with microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA, formerly known as Wegener’s granulomatosis). Ear, nose and throat (ENT) manifestations in AAV are relatively common and in some cases the first sign of the disease; in contrast, oral lesions are less frequent and described in only a very limited number of case reports of EGPA. Although not curable, AAV can be successfully managed with immunosuppressive drugs and other novel agents, highlighting the importance of early diagnosis. Methods Herein, we reviewed the results of a literature search for descriptions of oral lesions in EGPA. A literature review was conducted, consisting of a literature search, pragmatic searches of web sources and snowballing. Results The few cases reported document that oral lesions can occasionally be the first sign, albeit atypical, of the disease. Conclusions Healthcare professionals who examine the oral cavity, and especially otolaryngologists and dentists, should always consider EGPA in the differential diagnosis of oral lesions to avoid delayed diagnosis and, most importantly, the potentially fatal consequences of the vasculitic stage of the disorder.

Aim Bone augmentation in the atrophic maxilla is a prerequisite for successful implant rehabilitation. The aim of this study is to evaluate regeneration of bone and to compare the efficacy of PRF in bone regeneration following sinus augmentation surgery in the edentulous posterior maxilla. Materials and methods A prospective randomized comparative study was conducted at our institution. The study was allocated into 3 groups: Group I, Platelet Rich Fibrin (PRF) as a stand-alone agent; Group II, Autogenous bone graft; Group III, Alloplastic bone graft (Tricalcium phosphate putty). Groups II and III received PRF as an adjuvant. Results On comparing the post-operative bone height and radiodensity of the augmented region, there was statistical significance in Groups II and III. A 6 month post operative CBCT reveals a better bone regeneration in Group III (Alloplastic bone graft – β-Tricalcium phosphate putty). Conclusions The results of this study suggest that both autogenous and alloplastic bone grafts are viable graft materials for maxillary sinus augmentation. Platelet rich fibrin, when used as an adjuvant to either alloplastic or autogenous graft enhances bone formation by delivering growth factors at the site of regeneration. However, as a stand-alone agent it failed to provide radiographic evidence of bone formation. The posterior maxilla has always been the most challenging site for implant rehabilitation. There have been various studies, comparing different grafts for successful bone regeneration and stability after implant rehabilitation. Our study aims to search for an ideal grafting material in the maxillary sinus region.

Aims Intraoral scanners (IOS) are used for a wide range of treatments. Most IOSs produce data appropriate for local work, such as crowns, but evidence suggests that full-arch scans result in more erroneous scans, which may affect the fit of clinical appliances. There are no standardized methods for assessing the quality of IOSs. Though many studies have investigated the accuracy of scanners, one may find the reported values are difficult to interpret in a clinical context. Materials and methods This study investigated the trueness of two IOSs, using three metrics. The clinical value of each metric is discussed. A dentate model was scanned 10 times using two intraoral scanners. Three methods were used to assess the trueness of the scans against a scan produced in a laboratory scanner. Results The mean unsigned distance deviation between a laboratory scan and the Primescan scans was 0.016(±0.006)mm. The mean unsigned distance deviation between the laboratory scan and the Omnicam scans was 0.116(±0.01)mm. The arch width between molars was 55.44mm for the Solutionix scan. The arch width of the Primescan was 55.439(±0.075)mm, while the Omnicam reported 54.672(±0.065)mm. The mean proportion of the Primescan scans deviating beyond 0.1mm when compared against the Solutionix was 0.7(±2.0)%. The equivalent for the Omnicam was 42.1(±2.5)%. Conclusions All methods indicated significantly different results between the scanners. The Primescan produced truer scans than the Omnicam, regardless of measurement method. The intermolar-width and proportion beyond 0.1mm methods may give more clinically relevant insight into the trueness of scan data than current gold-standard methods.
