Knowledge and attitudes about dental trauma and mouthguard
Introduction
AbstractTo evaluate the knowledge and attitudes in a group of Brazilian physical education undergraduate students, relative to dental trauma and use of mouthguard. A total of 373 undergraduates from three public universities of Rio de Janeiro were interviewed by means of a semi-structured standardised questionnaire. The data were tabulated and analyzed using the statistical program SPSS, 17.0. Frequency was performed and it was also applied the qui-quadrado (p < 0.05) test, to establish a relation between variables of interest. Only 3.21% of the interviewees had been given information on dental trauma and use of mouth protector during their undergraduate course. With regard to their attitudes, only 19.83% responded correctly about how to act towards a tooth avulsion; 54.69% about how to manage the avulsed tooth, and 7.77% about how to transport the avulsed tooth. By comparing these attitudes in relation to the undergraduate period (before or after the 5th semester), previous information and experience on dental trauma, it was observed no signifi cant difference (p > 0.05). With regard to prevention, 89.81% knew mouthguard although only 17.96% wore it during sport activities. The students were given no information during their undergraduation course, even though the curriculum has the discipline of fi rst aid. The dentist are supposed to develop actions so that such knowledge meets the needs of the future physical education practitioners.
Background
A dentition with adequate function and esthetics is essential for the well-being and quality of life. A full implant-retained fixed prosthetics is an ideal solution for fully edentulous arch, however requires complex planning, surgical, and prosthetic procedure. With the help of digital workflow, it becomes a predictable and fast solution for the dentists and the patients. This retrospective study analyzed the most advanced surgical approach in full-arch rehabilitation with dental implants and immediate loading using digital workflow.
Methods
Patient records of fully edentulous jaws treated in four clinical centers in Warsaw, Poland, were evaluated. Computer-assisted planning and surgical template fabrication were done using the planning software coDiagnostiX™, based on a pre-op cone beam computed tomography (CBCT) and scanned data of a plaster model. A post-op CBCT was acquired after the placement of four to six implants by the guided system. The influence of different surgical variables on the discrepancy between planning and execution was analyzed, together with the biomechanical indices.
Results
A total of nine patient records were selected of 12 edentulous jaws treated with 62 implants. The overall mean three-dimensional (3D) offset at the implant base was 1.60 mm, at the tip 1.86 mm. The mean angle of deviation was 4.89°, the mean implant stability quotient (ISQ) 70.42, and the insertion torque 35.58 Ncm. The 3D offsets were influenced by the gender of the patient, treated jaw, the diameter, and length of the implant. The angle of deviation was affected only by the treated jaw. Insertion torque was influenced by the treated jaw, the age of the patient, the length of the implant, tooth type, and the side of the jaw.
Discussion
Bone quality of the patient and implant preparation procedure influenced the discrepancy between the planning and the execution of the digitally guided implant placement. Dense bone—mandible, posterior area, young age, and man—and multiple preparations of the implant bed—wider and longer implant—could be suggested as risk factors.
Conclusion
Digital workflow successfully enabled the immediate full-arch rehabilitation with a predictable outcome by different surgeons in multiple centers.
