Clinical and radiographic evaluation of maxillary central incisors exposure in patients undergoing maxillary advancement

Abstract: Introduction: Patients with dentofacial deformities may undergo orthodontic or orthodontic-surgical treatment. Both modalities can affect esthetics. Objective: This study aims to evaluate clinical and radiographic changes in exposure of maxillary central incisors occurring after orthognathic surgery for maxillary advancement. Methods: A total of 17 patients who underwent orthognathic surgery for maxillary advancement between September, 2010 and July, 2011 were selected. Exposure of maxillary central incisors was evaluated clinically and by lateral cephalograms. Measurements were taken one week before and three months after surgery. Data were paired in terms of sex, age, nasolabial angle, height and thickness of the upper lip, the amount of maxillary advancement, clinical exposure and inclination of maxillary central incisor by statistical tests (CI 95%). Results: After maxillary advancement, incisor clinical exposure had increased even with relaxed lips and under forced smile. Moreover, there was a mean increase of 23.33% revealed by lateral cephalograms. There was an inverse correlation between upper lip thickness and incisors postsurgical exposure revealed by radiographic images (p = 0.002). Conclusions: Significant changes in the exposure of maxillary central incisors occur after maxillary advancement, under the influence of some factors, especially lip thickness.

Reposicionamento horizontal mandibular com próteses provisórias removíveis tipo overlay – relato de caso Mandibular horizontal repositioning with removable temporary overlay prostheses – case report

Abstract: Introduction: Rehabilitation with the use of overlay-type removable prostheses is indicated in cases of more severe occlusal dysfunction. This type of treatment meets the need for more immediate results, providing aesthetic improvement while the rehabilitation work is being done, while promoting the gradual rehabilitation of occlusal function, re-adjusting the intermaxillary relationship. In addition, the patient can anticipate the final result of the treatment before the definitive prosthesis is made. Objective: To show a clinical case of planning and execution of removable overlays. Case report: JCF patient had occlusal dysfunction and presented as main complaint the aesthetic and functional deficiency. He used a removable partial denture (PPR) only on the upper arch. The existing prosthesis did not present stability due to the loss of some dental elements, pillars of the PPR. Two overlays (upper and lower) were indicated because the patient had good periodontal conditions in the remaining dental elements that were in a favorable position. Necessary exodontia, adequacy of the buccal environment with sub and supragingival scaling and the fabrication of overlays were performed. Conclusion: The use of temporary overlays can provide the necessary time for the patient to adapt to the new occlusal conformation in the period in which the restorations and definitive prostheses are expected to be performed. The use of overlays presented a satisfactory result for the proposed treatment, since it promoted the functional rehabilitation, restored aesthetic, even temporarily, and motivated the patient to continue the treatment. According to the patient, there were significant improvements in chewing quality and self-esteem.

Sustainable competitive advantage and green innovation: a review of joint scale propositions

Abstract: The objective of this work was to present the analysis instruments of Green Innovation that seek to relate it to Sustainable Competitive Advantage. Determining the research instruments through which we can analyze the relations between Organizational Capacity, Green Innovation, and Performance can enlighten us in what contributes with the levels of competitiveness of a specific industry, i.e., the sustainable competitive advantage. To do this, we focused on articles indexed in Thomson Reuters, ´Web of Science databank. We analyzed the articles have been most cited and which had presented scales for the analysis and understanding of Green Innovation instruments. We explored three of the most cited articles. These works address innovation from the perspective of Green Innovation and seek to analyze the superior performance of environmental innovations through specific scales. The studies in question adopt quantitative research approaches and operationalized through surveys. According to our analysis, the instruments can represent significant advances concerning the problem addressed in this study.
