Rehabilitation of Post-COVID-19 Mucormycosis Surgical Defect Using an Unconventional Obturator with Precision Attachments: A Case Report

Mucormycosis, also known as black fungus, is a rare fungal disease caused by a filamentous fungus that primarily affects the nose, paranasal sinuses, and brain. A significant number of mucormycosis cases were reported during the COVID-19 pandemic, many of which required surgical intervention. Parts of orofacial structures such as the alveolar process of the maxilla, palate, contents of the orbit, and nasal cavity were often removed to prevent a fatalities. The extent of hard tissue structures removed depended on the degree of involvement. Following surgical procedures, individuals were left with a variety of defects, ranging from lost alveolar processes and teeth to partial or total maxillectomy, and oronasal communication due to a missing palate. In such situations, Prosthodontists play a critical role in rehabilitating patients prosthetically. They analyse the defects in each case and design a prosthesis to replace the missing structures, aiding in the restoration of function and aesthetics. Hereby, the authors present a case report of 36-year-old-male with missing teeth in the upper left posterior and anterior regions and this clinical report aimed to describe an innovative aesthetic alternative to conventional cast partial obturators using OT attachments to achieve retention.

Automotive Technology Revolutionized Restorative Dentistry Discovery of Alpha-diketone/Amine Catalyst: Part II -Reflections on Photopolymerization from Conception to Development of Composite Resin and Activator Light.

A full account of the preceded early research tribulation that led to the development of the first visible light activated composite resin and the first visible light activator source is documented. The events took place over four years since early 1974 when a raw industrial composite resin that was radiolucent, stiff paste, universal optically opaque white color, polymerized by exposure to a prototype visible light for 120 seconds was given to developed. Four years later, the developed restorative composite resin ended up as a radiopaque, optically translucent, universal color with an additional three shades that possessed the biologic, esthetic, mechanical and physical characteristics with proven efficacy be used for esthetic zone. This conservative account of early development of a technology that must count as one of a small number of inventions during the seventies, over the years has revolutionized restorative dental practice. We were privileged and very lucky to be associated with developmental stages, stumbling blocks, and final success of the first LC Composite resin that ignited the thought process worldwide and laid the foundation for modern esthetic restoratives practiced today.

Prototype importance for implant supported zirconia bridges: a case report

Biocompatible esthetic restorations are necessary in order to obtain successful results with implant therapy. Monolithic zirconia is a more recently offered option to PFM and zirconia-ceramic prosthesis. The optical properties of zirconia have been greatly enhanced, approaching those of ceramics, while the monolithic nature of the prosthesis reduces the chance of fracture or chipping and improves its structural properties. The major drawback of theses zirconia is mechanical and thermal problems that encountered when zirconia is exposed to hydrothermal aging due to the transformation of the metastable tetragonal zirconia into the monoclinic form. This case report describes 45 aged adult female patient with anterior maxillary mobile teeth, after clinical and radiographical examination, extraction and socket preservation were done at periodontal department, 6 months later implant installed and after 3 months of healing, the patient referred to prosthodontic department. Screw retained temporary prosthesis were fabricated, composite build up were done intraorally for the temporary prosthesis to achieve the esthetic and functional occlusion. Cement retained implant supported fixed prosthesis using monolithic zirconia were cemented and no occlusal adjustment is needed thanks to the adjusted temporary prosthesis which served as prototype for a zirconia bridge with functional occlusion.

Lithium disilicate ceramic veneers as an alternative for aesthetic rehabilitation in upper anterior teeth: Case report

Ceramic dental veneers are currently a solution for long-term aesthetic rehabilitation of anterior teeth. As a conservative treatment, it allows maintaining a significant amount of dental tissue and at the same time achieving an acceptable aesthetic result. The clinical case of a 39-year-old female patient, professional, with no personal or family clinical pathological history, who came to the consultation due to presenting dissatisfaction with her smile and color of the teeth in the upper anterior sector, is presented. As an alternative for aesthetic rehabilitation, he was offered the application of lithium disilicate ceramic veneers on the upper anterior teeth. The technique was performed using lithium disilicate, allowing a reliable aesthetic restoration with minimal preparation of the dental tissue structure. Ceramic veneer restorations are highly durable and safe procedures when appropriate adhesive protocols are used. Lithium disilicate, in particular, exhibits superior strength to feldspathic ceramics and possesses superior optical properties to zirconium. For this reason, it is considered an ideal material for anterior aesthetic rehabilitation using ceramic veneers. The application of lithium disilicate ceramic veneers allows successful rehabilitation by combining desirable characteristics for both the professional and the patients, including aesthetics, high resistance and ease of use

Topographical Analysis of Human Enamel after Phosphoric Acid Etching and Er,Cr:YSGG Laser Irradiation.

Introduction: Dental hard and soft tissues have been successfully removed by using the Er,Cr:YSGG laser, but there is a controversy about using lasers over conventional tooth surface preparation for bonding aesthetic restoration. Surface roughness and wettability in response to Er,Cr:YSGG laser irradiation are essential properties for restoration longevity. Methods: Fifty-one intact human premolars removed in orthodontic treatment were included in this study and divided into three groups (n=17). The first group (G1) was the control without surface treatment, (G2) was treated with 37% phosphoric acid for 15 seconds, and (G3) was treated with the Er,Cr:YSGG laser using the following parameters: 2 W or 3 W at 20 Hz, 10% air and water ratio using the MZ6 laser tip. The standardization of laser irradiation was accomplished by a computerized numerical control unit. The surface of the samples was evaluated by using a light microscope, profilometer, atomic force microscopy (AFM), SEM, and wettability tests. Results: The SEM examination revealed that the lased enamel surface was clean, irregular, and devoid of a smear layer, while the acid etch surface was relatively smooth and covered with a smear layer. The surface roughness of the lased enamel surface was significantly higher than that of other groups, according to the results of the profilometer as well as the AFM tests. The wettability test showed that the lased enamel surface recorded a significant reduction in the contact angle in comparison to the other groups. Conclusion: It can be concluded that the Er,Cr:YSGG laser can be used as an alternative and safe method to the acid-etching technique for surface treatment.

Accurate tissue flap reconstruction method based on the quadratic surface developability for head and neck soft tissue defects

Soft tissue defects resulting from head and neck tumor resection seriously impact the physical appearance and psychological well-being of patients. The complex curvature of the human head and neck poses a formidable challenge for maxillofacial surgeons to achieve precise aesthetic and functional restoration after surgery. To this end, a normal head and neck volunteer was selected as the subject of investigation. Employing Gaussian curvature analysis, combined with mechanical constraints and principal curvature analysis methods of soft tissue clinical treatment, a precise developable/non-developable area partition map of the head and neck surface was obtained, and a non-developable surface was constructed. Subsequently, a digital design method was proposed for the repair of head and neck soft tissue defects, and an in vitro simulated surgery experiment was conducted. Clinical verification was performed on a patient with tonsil tumor, and the results demonstrated that digital technology-designed flaps improved the accuracy and aesthetic outcome of head and neck soft tissue defect repair surgery. This study validates the feasibility of digital precision repair technology for soft tissue defects after head and neck tumor resection, which effectively assists surgeons in achieving precise flap transplantation reconstruction and improves patients' postoperative satisfaction.

Application of 3D digital smile design based on virtual articulation analysis in esthetic dentistry: A technique

A technique for the application of a virtual articulation system in 3-dimensional digital smile design (DSD) during esthetic restoration is described. To acquire stable occlusion and a smooth jaw movement pattern without premature contacts or interference, a digital facebow and a virtual articulator were used to collect and analyze a patient’s occlusal data and jaw movement information. The original pattern of occlusal contacts and jaw movements were diagnosed as stable and copied to the digital design of the new prostheses. Preparation of the abutments, crown lengthening surgery, and definitive crown fabrication and cementation were performed according to the design. After 9 months, the occlusion remained stable, and the patient was satisfied with the outcome.

Digital PBL-CBL teaching method improves students' performance in learning complex implant cases in atrophic anterior maxilla.

The clinical teaching of esthetic implant-supported restoration of the atrophic maxilla is challenging due to the complexity and unpredictability of bone and soft tissue augmentation. The traditional problem-based learning and case-based learning method (PBL-CBL method) with a full digital workflow (digital PBL-CBL method) provides the students a chance to view clinical cases in a more accurate and measurable way. The aim is to evaluate the effectiveness of the new digital PBL-CBL method in teaching complex implant cases in esthetic area. A full digital workflow of dental implant therapy was established for patients with severely atrophic anterior maxilla. The digital data of cases done in the new workflow was used as teaching materials in digital PBL-CBL teaching. Fifty-four postgraduate students were randomly selected and divided into three groups, including traditional PBL-CBL group (students taught in a PBL-CBL method with no digital cases), digital PBL-CBL group (students taught in a PBL-CBL method with full digital cases) and control group (students taught in didactic teacher-centered method). After training for three months, a study of the students' opinions on the corresponding teaching method was carried out through a feedback questionnaire. A theory test was used to evaluate students' mastery of knowledge about tissue augmentation and esthetic implant restoration. A case analysis was used to determine whether students could apply the knowledge to problem solving. The digital PBL-CBL method resulted in a higher rate of satisfaction than the traditional PBL-CBL method and the didactic teacher-centered method in all items except for "This approach decreases extracurricular work". Case analysis scores of the digital PBL-CBL group were significantly higher than that of the traditional PBL-CBL group and the control group. For the theory test, the digital PBL-CBL group (61.00±6.80) but not traditional PBL-CBL group (55.22±9.86) obtained a significant higher score than the control group (45.11±12.76), although no significant difference was found between the digital PBL-CBL group and the traditional PBL-CBL group. Compared with other methods, students taught with the digital PBL-CBL method showed higher satisfaction and better performance in acquisition of academic knowledge and ability in solving practical clinical problems. The digital PBL-CBL method provided a promising alternative for teaching complex implant cases at the anterior maxilla.

Tratamento homeopático para hematoma aural em gato: Relato de caso

Aural hematoma is defined by the accumulation of serosanguineous fluid within the ear pinna in small animals, typically stemming from traumatic incidents. Inadequate treatment may lead to recurring episodes and structural deformities in the patient's ear. In veterinary clinical practice, this condition exhibits a high incidence among dogs, but is relatively rare in cats. Conventional treatments employed for the physiological and aesthetic restoration of the affected area are typically invasive and often entail significant costs. Therefore, this article aims to present a case study involving a 15-year-old female mixed-breed feline diagnosed with an aural hematoma. The patient had previously undergone various forms of conventional treatment, none of which proved successful. Thus, a complementary treatment approach utilizing oral homeopathy was selected, as it represented the sole available option at that particular juncture. The homeopathic medicines were selected according to the law of similars. The treatment consisted of the following medications: Arsenicum album 30CH; Bellis perennis 30CH and Rhus Toxicodendron 30CH. After 20 days of treatment, the animal exhibited an ear pinna devoid of fluid accumulation and recurrence. The ear pinna was in excellent condition, except for the presence of scars along the ear, resulting in a residual deformation. Hence, homeopathic therapy holds significant promise as a therapeutic modality for managing aural hematomas in cats, obviating the necessity for invasive procedures. Under this perspective, this article represents one of the initial reports documenting such a treatment approach in feline cases.

Guided Autotransplantation of an Immature Premolar to the Maxillary Incisor Region with Immediate Restoration of Esthetics: A Case Report

This case report describes the treatment of two maxillary central incisors following a traumatic injury with tooth #8 developing replacement resorption and #9 developing inflammatory root resorption. A 10-year-old girl presented complaining of pain in her maxillary central incisors. Upon clinical examination, teeth #8 and #9 were tender to percussion and palpation of the buccal soft tissues. Thermal and electrical pulpal sensitivity tests for teeth #8 and #9 were negative. An intraoral periapical radiograph revealed resorptive defects in tooth #8, which were filled with bone-like tissue, while tooth #9 had radiolucent resorptive defects along the root surface and a periapical radiolucency. A diagnosis of replacement resorption was made for tooth #8 and external inflammatory root resorption for tooth #9. Tooth #8 was treated with a multidisciplinary approach utilizing a guided template for premolar autotransplantation with an immediate veneer restoration, while tooth #9 was managed with root canal treatment using a tricalcium silicate cement to fill the canal. At the 1, 4, 8, 12, and 24-month follow-ups, the patient remained asymptomatic, and there was no radiographic evidence of root or periapical pathosis on either tooth. The root-end of the donor tooth transplanted to the #8 site continued to develop. This case report highlights successful interdisciplinary management of two forms of root resorption using modern treatment strategies that provided immediate function and esthetics to the maxillary central incisors in a young patient following trauma.

Computer-aided design and computer-aided manufacturing poly (methyl methacrylate) interim veneers for immediate esthetic restoration of autotransplanted teeth.

Autotransplanted teeth in the maxillary anterior region should be restored or reshaped as soon as possible for functional and esthetic reasons as well as the well-being of the patient. However, such tooth restorations are frequently not carried out immediately after tooth transplantation because the process could have a negative impact on the healing process. The development of a simple, immediate, and atraumatic esthetic interim restoration would be of great benefit to both the clinician and patient and address all the concerns caused by immediately preparing the tooth postoperatively and cementing a permanent restoration. This report describes the use of CAD-CAM technology to create poly (methyl methacrylate) veneers preoperatively that can be cemented extraorally on the extracted donor tooth for the immediate and interim recontouring of autotransplanted anterior teeth.

Craniofacial Fibrous Dysplasia in Fronto-Orbital Region: A Single-Center Retrospective Study of 38 Cases

This study presents the clinical characteristics, imaging manifestations, and surgical experience in 38 patients diagnosed with craniofacial fibrous dysplasia in fronto-orbital region (foFD). We retrospectively analyzed the clinical data from 38 patients who had surgery for foFD. The surgical procedure typically involved extensive tumor removal, followed by immediate reconstruction of the frontal bone and orbit using synthetic materials. Additionally, 9 patients underwent simultaneous microscopic decompression of the optic canal. Common clinical manifestations included progressive fronto-orbital bone deformity (35), proptosis (28), orbital dystopia (21), and visual impairment (9). The disease primarily affecting the frontal bone (38), the sphenoid bone (28), and the ethmoid bone (24). The optic canal was involved in 9 patients with functional impairment. Computed tomography scans in all 38 cases revealed satisfactory repair material positioning and complete resolution of frontal deformities. Among the 9 patients who underwent optic canal decompression, 7 experienced partial recovery of visual acuity after surgery. In the surgical treatment of foFD, it is crucial to achieve maximal bone resection and repair skull defects, while decompressing the optic canal can provide significant benefits for patients with decreased visual function preoperatively. The use of preformed artificial materials offers advantages in aesthetic restoration after lesion excision.
