This research aimed to develop an experimental animal model for the evaluation of the posterior maxillary alveolar bone and further selection of the design for a dental implant with high osseointegration potential.Ten dried skulls of common adult dogs, Canis familiaris, were used in this study. In order to achieve the experimental model, two working methods were performed: imaging morphometry and direct morphometry. The measurements were accomplished for the purposes of determining the dimensions of the buccal and palatal alveolar cortical bone in the target location, the maxillary premolar region. The width and height of available bone were also recorded. Data analysis was performed using Student's t-test (P ≤ 0.05) and the Stata MP/13 software.Comparable results were obtained by both imaging and direct morphometry methods. The experimental implant was customized from the dimensional point of view and considering the most appropriate implant design.
This study represents a review of the literature on the topography of the mandibular canal. A PubMed and MedLine search was performed alongside with a hand search of specialised books. 193 abstracts, 41 full articles and 12 books were used for the study, out of which 93 were included in the references list. The region of the mandibular body behind the first premolar contains the mandibular canal, which presents a certain trajectory in relation with the lateral teeth apices and in relation with the buccal and lingual cortical plates. The mandibular canal is considered an important anatomic landmark that can influence the success of endodontics, oral surgery procedures and implant therapy.
This study is a review of the specialised literature regarding the intraoral autogenous bone grafts used in oral implantology. 382 abstracts of scientific papers, 71 full-text scientific articles and 9 specialized books, out of which 113 included in the references, were studied. The area behind the mandibular third molar, the posterior buccal area of the mandible body and the mandibular symphysis are the most frequently used sites for intraoral block bone harvesting. The mandible should be the first choice in the intraoral donor site selection for peri-implant augmentation, if the quantity of bone that is going to be harvested is considered to be enough.
The major risk of dental implant treatment in the mandible is represented by the mandibular canal. Precise location of the mandibular canal is essential for oral rehabilitation with dental implants. The aim of this study was to analyze the topography of the mandibular canal in order to increase the long-term performance of oral rehabilitation with dental implants in „poor areas“. The topography of the mandibular canal was statistically studied on 11 human mandibles. The results obtained show similarities but also differences with data reported in other specialized references.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
