The surgical procedure for the clinical crown lengthening, aims for an aesthetic or functional form to compensate for the reabsorption of the alveolar bone tissue caused by the invasion of the biological space. The conditions that must be taken into account during surgical planning are related to an excessive gingival exposure, altered passive eruption and lack of height of the dental element for restorative purposes. The objective of this systematic review was to evaluate in the scientific literature the minimally invasive surgical techniques used to clinical crown lengthening. A systematic review of the literature was performed using the databases, Science Direct, Embase, Cochrane Collaboration Library, and PubMed/MEDLINE. The search strategy provided a total of 157 studies. After selection, five articles met all the inclusion criteria and were included in this systematic review. Studies have shown that conventional surgical techniques for clinical crown lengthening are presented as an effective approach that promotes good aesthetic and functional results. However, they have some limitations. After evaluating the minimally invasive surgical techniques included in this systematic review, it was possible to infer that they presented satisfactory results in the soft and hard tissue contouring, with no complications and dissatisfaction being observed by the patients.

Introduction: The objective of this systematic review is to assess the effect of vibrational force on biomarkers for orthodontic tooth movement. Methods: An electronic search was conducted for relevant studies (up to December 31, 2020) on the following databases: Pubmed, Google scholar, Web of Science, Cochrane Library, Wiley Library, and ProQuest Dissertation Abstracts and Thesis database. Hand searching of selected orthodontic journals was also undertaken. The selected studies were assessed for the risk of bias in Cochrane collaboration risk of bias tool. The “traffic plot” and “weighted plot” risk of bias distribution are designed in the RoB 2 tool. The 2 authors extracted the data and analyzed it. Results: Six studies fulfilled the inclusion criteria. The risks of biases were high for 4, low and some concern for other 2 studies. The biomarkers, medium, device, frequency and duration of device, as well as other data were extracted. The outcomes of the studies were found to be heterogenous. Conclusion: One study showed highly statistically significant levels of IL-1 beta with <.001. Rate of tooth movement was correlated with levels of released biomarkers under the influence of vibrational force in 3 studies, but it was found to be significant only in 1 study. It was further observed that vibration does not have any significant reduction in pain and discomfort.

Abstract OBJECTIVE Metastatic epidural spinal cord compression is a potentially devastating complication of cancer and is estimated to occur in 5% to 14% of all cancer patients. It is best treated surgically. Minimally invasive spine surgery has the potential benefits of decreased surgical approach–related morbidity, blood loss, hospital stay, and time to mobilization. CLINICAL PRESENTATION A 36-year-old man presented with worsening back pain and lower extremity weakness. Workup revealed metastatic adenocarcinoma of the lung with spinal cord compression at T4 and T5. INTERVENTION AND TECHNIQUE T4 and T5 vertebrectomy with expandable cage placement and T1–T8 pedicle screw fixation and fusion were performed using minimally invasive surgical techniques. RESULT The patient improved neurologically and was ambulatory on postoperative day 1. At the 9-month follow-up point, he remained neurologically intact and pain free, and there was no evidence of hardware failure. CONCLUSION Minimally invasive surgical circumferential decompression may be a viable option for the treatment of metastatic epidural spinal cord compression.
