Several orthopedic procedures have been used in early treatment to reduce the need for orthognathic surgery in skeletal Class III.\nThe most used treatment is Rapid Maxillary Expansion and Facemask. This procedure also determines a clockwise rotation of the\nmandible, increasing the vertical dimensions of the lower third of the face. Therefore, the control of vertical dimension appears to\nbe a key objective in Class III hyperdivergent patients. This article shows two skeletal Class III patients treated with a new appliance\n(Pushing Splints 3), that is able to correct sagittal discrepancy with a good control of the vertical growth. In both cases, Class I\nrelationship with a proper Overjet and Overbite was achieved with improvement of profile. The final cephalometric values\ndemonstrated a stable sagittal relationship and a good control of the vertical growth. The specific biomechanic features of the\nPS3 appliance permit the improvement of the sagittal jaw relationship, delivering at the same time vertical vectors that are able\nto control the alveolar and skeletal components of the vertical growth. This could be useful in the treatment of Class III\nhyperdivergent patients....
The objective of this clinical case is thus to present a Class II, division 1, subdivision malocclusion with a severely extruded\nmaxillary left hemiarch, which, due to the loss of mandibular teeth, makes prosthetic rehabilitation of the edentulous spaces\nimpossible. A significant intrusion was performed with mini-implants followed by miniplates associated with fixed appliance\nand elastomeric chains. The results of this process showed that the biological responses of the teeth and the surrounding bony\nstructure to the intrusion were demonstrated to be normal and acceptable. A clinically significant intrusion of the left maxillary\nmolars, along with the recovery of the interocclusal space and the prosthetic rehabilitation, was obtained with a fixed\northodontic appliance that was associated to the biomechanics with TADs. It also allowed the obtaining of Class I canine\nrelationship, demonstrated periodontal health and favored the prosthetic rehabilitation with good occlusion, aesthetics, and\nsatisfactory function....
The onset and persistence of endodontic infections due to residual biofilm after chemical\ndisinfection promotes secondary bacterial infection. Alternative methods to disinfect operated root\ncanals are a matter of great interest. The aim was to evaluate the antibacterial effectiveness of\nsodium hypochlorite (NaOCl) at low concentrations activated by the Er,Cr:YSGG laser-activated\nirrigation (LAI) against 10-day-old intracanal Enterococcus faecalis biofilm. Biofilms were formed\ninside the root canals and divided into 7 groups (n13): 0.5% NaOCl + Er,Cr:YSGG; Saline +\nEr,Cr:YSGG; 0.5% NaOCl + syringe irrigation(SI); 2.5% NaOCl + SI; 5% NaOCl + SI; positive and\nnegative controls. Bacterial survivors were counted and specimens visualized under scanning\nelectron and confocal laser scanning microscopy. Treatments with 0.5% NaOCl + Er,Cr:YSGG and\n2.5% NaOCl + SI gave a significant reduction in the number of CFU/mm2. Moreover, scanning\nelectron microscopy and confocal laser scanning microscopy imaging confirmed and reinforced\nbacteriological data. Thus, Er,Cr:YSGG LAI proved to be able to improve the intracanal distribution\nof 0.5% NaOCl after 60 s of activation, reaching the same level of effectiveness than 2.5% NaOCl.\nThis is regarded as of clinical interest, since working with lower concentrations may contribute to\nreduce undesired effects....
Tooth loss among adults is associated with progressive periodontitis. Implant prosthetic treatment has long been utilized in\nperiodontal patients. Even when the implants are applied, ongoing management of periodontal disease and control of\ninflammation is necessary to maintain a healthy oral cavity. Lack of appropriate periodontal treatment can result in recurrence\nof periodontal disease during a maintenance period; loss of the supportive capacity of the periodontal tissues will increase the\nsusceptibility of residual teeth to traumatic force. For this reason, it is worthwhile to improve oral function by applying implants\nas a fixed device. Here, we report that implant treatment in a patient with generalized severe chronic periodontitis helped\nmaintain the periodontal and peri-implant tissue for a long term. We propose that initial periodontal treatment and ongoing\nsupportive therapy can help maintain implants in patients with severe periodontitis. In addition, we reviewed case reports in the\nEnglish literature so far....
Pink tooth of Mummery is typically found after trauma. However, this case report describes an unusual occurrence of pink tooth in\na 67-year-old Caucasian male after fixed partial denture (FPD) tooth preparation. Pink tooth in this case may be due to one or more\nfactors: tooth reduction and heat generation during tooth preparation; heat generation during polymerization of provisional\nmaterial; and hyperocclusion of a provisional FPD. This case highlights the importance of choosing the appropriate materials\nand techniques to avoid pulpal complications after dental prosthesis work....
Implant placement in severely atrophic jaws is especially challenging because\nof the poor quality and quantity of the future implant bed. Although various\nbone augmentation procedure like ridge augmentation, sinus lift these procedures\nare possible today but it may lead to surgical morbidity they increase\nthe risks and costs of dental implant treatment as well as the number of necessary\noperations. Also sometimes the patient is not agreeing for such extensive\nsurgical procedures, according to the well-known implantological rules\nfor dental restorations, crestal implants are indicated in situations when an\nadequate vertical bone supply is given but single piece dental implant (basal\nimplants) is a viable treatment option derives support from the basal bone\narea which usually remains free from the infection and less prone to resorption....
Tooth extraction in patients treated with bisphosphonates (BPs) for osteoporosis or cancer\nexposes the patient to the risk of osteonecrosis of the jaw. An autologous membrane using platelet-rich\nfibrin (PRF) is an innovative technique to promote wound healing, which allows obtaining a hermetic\nclosure of the post-extractive surgical site without the need of mucoperiosteal flaps or periosteal\nreleasing incisions. Here, we report the case of a 70-year-old woman, in therapy with alendronate\nfor 12 years, requiring the upper right premolar extraction because of a crown fracture. After the\ntooth extraction performed under antiseptic and antibiotic coverage, the PRF autologous membrane\nwas placed on the surgical wound to close completely the post-extraction site. Follow-up visits\nwere carried out after one, two, four weeks and two months from the intervention. The complete\nre-epithelization of the wound was observed without signs of infection. The use of PRF for the closure\nof post-extraction sockets in patients taking BPs appears to be a promising alternative to the more\ninvasive surgical procedures. Future clinical trials will be pivotal in elucidating the effectiveness of\nPRF to prevent BP-related osteonecrosis after tooth extraction....
