Background: The purpose of this paper is to review the available literature on three-dimensionally printed complete dentures in terms of novel biomaterials, fabrication techniques and workflow, clinical performance and patient satisfaction. Methods: The methodology included applying a search strategy, defining inclusion and exclusion criteria, selecting studies and forming tables to summarize the results. Searches of PubMed, Scopus, and Embase databases were performed independently by two reviewers to gather literature published between 2010 and 2020. Results: A total of 126 titles were obtained from the electronic database, and the application of exclusion criteria resulted in the identification of 21 articles pertaining to printed technology for complete dentures. Current innovations and developments in digital dentistry have successfully led to the fabrication of removable dental prostheses using CAD/CAM technologies. Milled dentures have been studied more than 3D printed ones in the currently available literature. The limited number of clinical studies, mainly case reports, suggest current indications of 3D printing in denture fabrication process to be custom tray, record bases, trial, interim or immediate dentures but not definitive prostheses fabrication. Limitations include poor esthetics and retention, inability to balance occlusion and low printer resolution. Conclusions: Initial studies on digital dentures have shown promising short-term clinical performance, positive patient-related results and reasonable cost-effectiveness. 3D printing has potential to modernize and streamline the denture fabrication techniques, materials and workflows. However, more research is required on the existing and developing materials and printers to allow for advancement and increase its application in removable prosthodontics....
(1) Background: Three-dimensional printing is progressing rapidly and is applied in many\nfields of dentistry. Tooth autotransplantation offers a viable biological approach to tooth replacement\nin children and adolescents. Restoring or reshaping the transplanted tooth to the anterior maxilla\nshould be done as soon as possible for psychological and aesthetic reasons. However, to avoid\ninterfering with the natural healing process, reshaping of transplanted teeth is usually delayed\nthree to four months after transplantation. This delay creates a need for simple indirect temporary\naesthetic restoration for autotransplanted teeth. The aim of this study was to develop and validate a\ndigital solution for temporary restoration of autotransplanted teeth using 3D printing. (2) Methods:\nFour dry human skulls and four dry human mandibles were scanned using cone beam computed\ntomography to create 3D models for 15 premolars. Digital impression of the maxillary arch of one of\nthe skulls was captured by intra oral scanner. The digital work flow for the design and fabrication\nof temporary veneers is presented. The seating and adaptation of the 3D printed veneers were\nevaluated using stereomicroscopy and micro-computed tomography. (3) Results: Evaluation of the\nveneer seating using stereomicroscopy showed that the mean marginal gap at all of the sides was\nbelow the cut-off value of 200 micron. The overall mean marginal gap was.....................
To ensure a successful dental implant therapy, the presence of adequate vertical and horizontal alveolar bone is fundamental.\nHowever, an insufficient amount of alveolar ridge in both dimensions is often encountered in dental practice due to the\nconsequences of oral diseases and tooth loss. Although postextraction socket preservation has been adopted to lessen the need for\nsuch invasive approaches, it utilizes bone grafting materials, which have limitations that could negatively affect the quality of bone\nformation. To overcome the drawbacks of routinely employed grafting materials, bone graft substitutes such as 3D scaffolds have\nbeen recently investigated in the dental field. In this review, we highlight different biomaterials suitable for 3D scaffold fabrication,\nwith a focus on ââ?¬Å?3D-printedââ?¬Â ones as bone graft substitutes that might be convenient for various applications related to implant\ntherapy.We also briefly discuss their possible adoption for periodontal regeneration....
Background. A radicular cyst is the most common odontogenic cyst of inflammatory origin. Radiographically, it commonly\ndemonstrates clear unilocular radiolucency; radicular cysts with multilocular radiolucency are quite rare. Case Presentation. A\n64-year-old Japanese man who presented with a bilocular radiolucent lesion in his left mandible was referred by a dental clinic\nto our oral and maxillofacial surgery department. He had no particular subjective symptoms. Orthopantomography and\ncomputed tomography (CT) revealed an 18mm*15mm lesion with well-defined bilocular radiolucency in the left mandible\nexpanding from the distal side of a canine tooth to the bottom of the 2nd premolar. The lesion included the roots of the 1st and\n2nd premolars. The root of the 2nd premolar showed knife-edge resorption. Although the 1st premolar was nonvital, the 2nd\npremolar was a vital tooth. As differential diagnoses, a radicular cyst, ameloblastoma, odontogenic keratocyst, pseudocyst, and\nothers might be considered. We performed a total resection of the bilocular lesion and diagnosed the lesion as a radicular cyst\nwith tooth structure components inside. The tooth structure components represented lamellar structures of cementum; they\nwere located only in the proximal part (under the 1st premolar) of the lesion. The distal part of the lesion presented distinctive\ninflammation without tooth structure components. Conclusion. We encountered a rare case of a bilocular radicular cyst with\ntooth structure components inside....
Background/Objectives: This study investigates the temperature changes on the external root surface during root canal preparation using different rotary systems and assesses the impact of irrigation temperatures. Methods: Sixty extracted human maxillary incisors were divided into four groups based on the rotary system used: ProTaper Next (Dentsply Sirona, Ballaigues, Switzerland), Reciproc Blue (VDW GmbH, Munich, Germany), WaveOne Gold (Dentsply Sirona, Ballaigues, Switzerland), and TruNatomy (Dentsply Sirona, Ballaigues, Switzerland). These systems differ in cutting efficiency and design. Temperature measurements during instrumentation and irrigation were recorded using a FLIR E60bx thermal camera (Teledyne FLIR LLC, Hudson, NH, USA). Irrigations were conducted with sodium hypochlorite at room temperature and heated to 60 ◦C. Results: The ProTaper Next group exhibited the highest average temperature increase during instrumentation (5.2 ◦C), followed byWaveOne Gold (4.3 ◦C), Reciproc Blue (3.7 ◦C), and TruNatomy (2.8 ◦C). During irrigation with heated sodium hypochlorite, temperature rises recorded were 6.8 ◦C for ProTaper Next, 5.9 ◦C for WaveOne Gold, 5.2 ◦C for Reciproc Blue, and 4.1 ◦C for TruNatomy. Statistical analysis revealed a significant negative correlation between dentin thickness and temperature rise, with rvalues ranging from −0.62 to −0.87 across the groups. No significant correlation was found between canal diameter and temperature change, indicating that the canal’s size does not influence the thermal impact as much as the properties of the rotary system and irrigation temperature. Conclusions: Different rotary systems produce varying levels of temperature increases on the external root surface, influenced significantly by the thickness of the dentin and the temperature of the irrigation solution. These variations necessitate careful selection of instrumentation and irrigation protocols to minimize potential thermal damage to surrounding periodontal tissues....
Objective To assess the maxillofacial growth of patients with isolated cleft palate following the Sommerlad-Furlow modified technique and compare it with the effect of the Sommerlad technique. Study design A Retrospective Cohort Study. Methods A total of 90 participants, 60 patients with non-syndromic isolated soft and hard cleft palate (ISHCP) underwent primary palatoplasty without relaxing incision (30 patients received the Sommerlad-Furlow modified (S-F) technique and 30 received Sommerlad (S) technique). While the other 30 were healthy noncleft participants with skeletal class I pattern (C group). All participants had lateral cephalometric radiographs at least 5 years old age. All the study variables were measured by using stable landmarks, including 11 linear and 9 angular variants. Results The means age at collection of cephalograms were 6.03 ± 0.80 (5–7 yrs) in the S group, 5.96 ± 0.76 (5–7 yrs) in the S-F group, and 5.91 ± 0.87 (5–7 yrs) in the C group. Regarding cranial base, the results showed that there were no statistically significant differences between the three groups in S–N and S–N-Ba. The S group had a significantly shortest S-Ba than the S-F & C groups (P = 0.01), but there was no statistically significant difference between S-F and C groups (P = 0.80). Regarding skeletal maxillary growth, the S group had significantly shorter Co-A, S- PM and significantly less SNA angle than the C group (P = < 0.01). While there was no significant difference between S-F & C groups (P = 0.42). The S group had significantly more MP-SN inclination than the C group (P = < 0.01). Regarding skeletal mandibular growth, there were no statistically significant differences in all linear and angular mandibular measurements between the three groups, except Co-Gn of the S group had a significantly shorter length than the C group (P = 0.05). Regarding intermaxillary relation, the S-F group had no significant differences in Co-Gn—Co-A and ANB as compared with the C group. The S group had significantly less ANB angle than S-F & C groups (P = 0.01 & P = < 0.01). In addition, there were no significant differences in all angular occlusal measurements between the three groups. Conclusion As a preliminary report, Sommerlad-Furlow modified technique showed that maxillary positioning in the face tended to be better, and the intermaxillary relationship was more satisfactory than that in Sommerlad technique when compared them in healthy noncleft participants....
The aim of this study was to make a comparison of the compressive properties of the goat temporomandibular joint (TMJ) disc to\nthe mandibular condylar cartilage (MCC) and to explore the transversely isotropic biphasic model. Samples taken mediolaterally\nfrom three regions of the TMJ disc and MCC were tested in unconfined compression at strain levels ranging from 10% to 50%\nand then assessed for biochemical content. The results indicated that the TMJ disc exhibits a significantly greater tangent modulus\nthan the MCC from 20% to 50% strain with values ranging from 729 �± 267 to 2413 �± 406 kPa and 363 �± 169 to 1677 �± 538 kPa,\nrespectively (P < .05). The collagen content of the TMJ disc was significantly greater than the MCC, while the opposite held for\nthe glycosaminoglycan (GAG) and DNA content. The results emphasize fundamental differences between the articulating tissues\nof the TMJ....
Background: Accidents involving the maxillofacial area are sudden and unforeseen, such as traffic accidents and physical altercations. The COVID-19 pandemic was a critical threat to the public in aspects not only involving physical health but also those affecting psychological health due to isolation, leading to a higher incidence of stress and depression among the general population and specifically in patients with OMF trauma. This study assessed the relationship between the impact of the COVID-19 pandemic and the quantity and severity of maxillofacial injuries. Methods: Data were retrieved from the Department of Maxillofacial Surgery of the University Clinical Centre in Gdansk from March 2019 to August 2023. Results: There was an increased risk of injury occurrence to the condylar process of the mandible, especially the left side, Le Fort type II/III fractures, injuries of the maxillary alveolar process, and displacement of the upper facial mass. Simultaneously, a decreased occurrence of certain injuries i.e., Le Fort type III fractures and Le Fort type I/II fractures, was recorded. Conclusions: The COVID-19 pandemic led to an increased occurrence of high-energy injuries, including displacement of the upper facial mass (p = 0.010)....
Background: Anecdotal reports assert a relationship between weather and lunar activity and the odontogenic\nabscess (OA) incidence, but this relationship has not been validated. Therefore, the present study investigated the\nrelationship between oral pain caused by OA and a variety of meteorological parameters and cyclic lunar activity.\nMethods: The records of all dental emergency patients treated at the AllDent Zahnzentrum Emergency Unit in\nMunich, Germany during 2012 were retrospectively reviewed. Patients with oral pain who were diagnosed with\nOA and treated surgically (n = 1211) were included in the analysis. The OA incidence was correlated to daily\nmeteorological data, biosynoptic weather analysis, and cyclic lunar activity.\nResults: There was no seasonal variation in the OA incidence. None of the meteorological parameters, lunar phase,\nor biosynoptic weather class were significantly correlated with the OA incidence, except the mean barometric\npressure, which was weakly correlated (rho = -0.204). The OA incidence showed a decreasing trend as barometric\npressure increased (p < 0.001). On multiple linear regression, the barometric pressure accounted for approximately\n4% of the OA incidence.\nConclusion: There is no evidence supporting a correlation between the incidence of odontogenic abscess and the\nweather and lunar activities...
water solubility of new sealers should be studied. This study aimed to assess the water solubility\r\nof five root canal sealers (AH-26, Topseal, 2-Seal, Acroseal, and Roeko Seal Automix [RSA]).\r\nMaterials and Methods: In this in vitro experimental study, 30 specimens were fabricated from\r\neach of the abovementioned sealants. Then they were weighed and randomly divided into three\r\nsubgroups of 10 each (A, B, and C). They were set at 37�°C and 100% RH, in accordance with ANSI/\r\nADA 57 and ISO 6876-2001 requirements. Afterward, the specimens in subgroups A were incubated\r\nat 37�°C and 100% RH for 24 hours, while the specimens in the subgroups B and C were incubated\r\nin the same conditions for 7 days and 28 days, respectively. After incubation, the specimens were\r\ndried with blotting paper and were incubated for 24 hours at 37�°C and 0% RH. Then they were\r\nweighed. The percentage of weight loss was regarded as water solubility.\r\nResults: The mean solubility of the sealers AH-26, Acroseal, Topseal, 2-Seal, and RSA were 0.28%,\r\n0.36%, 0.07%, 0.037%, and 0.141% after 24 hours, respectively. After 28 days, their solubility were\r\n1.75%, 0.746%, 0.082%, 0.04%, and 0.517%, respectively. Only the solubility of the sealers 2-Seal\r\nand Topseal were not statistically different (P>0.3 [Tukeyâ��s]). Again only the solubility of 2-Seal and\r\nTopseal did not significantly increase between the 7th day and the 28th day of incubation (P>0.6\r\n[paired-samples t]).\r\nConclusion: All tested materials met the standards (maximum weight loss of 3% within 24 hours).\r\nHowever, the results of 2-Seal followed by Topseal were the most favorable ones....
