“…8,14 The study ndings suggest infrequent utilization of space maintainers, however, potential consequences of not tting space maintainers, such as space loss and potential orthodontic problems have been well reported and must be considered when making decisions. 24 It is possible that a child having enforced extractions for caries may not be a suitable candidate to have a space maintainer tted, since the device requires more disciplined cleaning.…”

Introduction: Balancing and compensating extractions (BCEs) of primary teeth aims to minimize the development of more severe malocclusions and reduce the need for subsequent complex orthodontic treatment. Purpose: To assess the demographics, practice characteristics, and clinical preferences of United Kingdom (UK) paediatric dentists for BCEs of primary teeth, to determine adherence to national clinical guidelines and whether paediatric dentists refer patients to orthodontists before deciding on BCEs. Methods: This was a total population online survey of members of the British Society of Paediatric Dentistry (BSPD). A pre-tested, self-administered electronic questionnaire was accessed through a secure website. Questions offered frequency options (always/frequently, often/sometimes and rarely/never) for a range of clinical scenarios in patients up to 5 years and those between 6 and 9 years. Descriptive statistics in the form of percentages were presented. To compare single population/sample percentages, a Pearson Chi-square goodness-of-fit (GOF) test with post hoc pairwise binomial analysis and Bonferroni adjustments was performed. Results: Of the 288 specialists invited, 67 (23.3%) completed the questionnaire. Respondents were mostly female (n=55; 82.1%), with most respondents working in secondary care (n=51; 77.3%). The majority (n=54; 81.8%) supported the application of guidelines for primary teeth extractions. Thirty-nine paediatric dentists (58.2%) always/frequently encountered BCEs, with 29 (46.2%) performing BCEs in over 40 patients in the past year. Forty respondents (59.7%) reported always/frequently complying with national clinical guidelines for primary teeth extractions. Data from 65 respondents indicates that 83.6% (n=56) rarely/never made referrals to an orthodontist, whilst 65.7% (n=44) rarely/never consulted an orthodontist (p < 0.001). Conclusions: The results reveal significant decision variation across clinical scenarios, with good adherence to guidelines in BCEs of primary teeth among paediatric dentists. However, there is limited interdisciplinary collaboration, as indicated by the infrequent referrals or consultations with orthodontists when considering BCEs of primary teeth.

“…There is also the direct bonded space maintainer, which uses a stainless steel wire (0.028) bent and adjusted according to the extraction space [20], is inexpensive and easy to fabricate, but susceptible to decementation or fracture [10,21]. Finally, the fiberglass-reinforced resin space maintainer is esthetic and minimally invasive, made of prefabricated fibers and light-curing resin, although it is inexpensive and has minimal effects on soft tissue, requires precise handling with adequate isolation and may de-cement if the cementation procedure is not carefully followed [22].…”

Introduction: 3D and CAD/CAM technology has now been widely adopted by most dentists and pediatric orthodontics is no exception. This technology allows orthodontists to create digital dental models, thus facilitating the design and fabrication of orthopedic appliances customized to the specific needs of each patient. Objective: To gather scientific information that describes in detail the management, advantages and disadvantages of using CAD/CAM and 3D technology in the fabrication of space maintainers. Materials and methods: A search was carried out in several databases, including PubMed, Scopus, Springer link, Science Direct and Google Scholar. Fourteen articles that met the inclusion criteria were selected. Results: 10 studies used materials such as polyetheretheretherketone, polymethylmethacrylate and polymer (Trilor), milled to produce space maintainers. Another 3 studies applied titanium powder with addition 3D printing techniques for the same purpose and finally, 1 study used a zirconium block (BruxZir) to manufacture a band by milling. Conclusions: Digital space maintainers (DSM) show comparable results to conventional space maintainers (CSM), with the additional advantage of being more stable and resistant. Although their cost may represent a limitation, further studies and long-term follow-ups are recommended to take advantage of the benefits of technological innovation in the manufacture of space maintainers and improve the quality of patient care.

The potential of stem cells, for example upper periodontal ligament stem cells from the maxilla (u-PDLSC) and from the mandible (l-PDLSC), adipose-derived mesenchymal stem cells (AD-MSC), and bone marrow-derived mesenchymal stem cells (BM-MSC), with respect to periodontal remodeling and orthodontic treatment is of great importance. In this work, we focus on the comprehensive adaptability of different stem cell types to mechanical forces with the aim to better understanding cell behavior and to refine a new mechanistic approach to investigate periodontal remodeling. We comprehensively analyze stem cells and observe distinct morphological and proliferation changes under compression in dependence on stem cell type. The cell signaling of extracellular signal-regulated kinase (ERK) and protein kinase B, also called AKT, and their respective phosphorylation shows diverse responses to compression. Additionally, vascular endothelial growth factor and hepatocyte growth factor secretion were reduced under mechanical stress in all cell types, with cell-specific variations. Osteoprotegerin secretion was reduced under compression, particularly in u-PDLSC. At least, diverse soluble receptors of NF-kB-ligand secretion patterns among cell types under pressure were observed, providing crucial insights into bone metabolism. These findings offer a deeper understanding of the behavior of mesenchymal stem cells under mechanical stimuli, highlighting their roles in bone remodeling, wound healing, and tissue regeneration in orthodontic and regenerative medicine contexts. Our results underscore the potential of u-PDLSC, l-PDLSC, and AD-MSC in periodontal regeneration, with AD-MSC showing notable resilience under compression, indicating its promising role for further investigation for orthodontic research. While these findings are encouraging, further research is essential to fully comprehend the mechanism of stem cell-based periodontal therapies.
