Introduction: Accurate dental implant placement is essential to achieve predictable prosthetic, functional, and biological outcomes, as well as to reduce the risk of complications associated with improper implant positioning. Objective: To compare the angular, coronal linear, and apical linear deviations of dental implants placed using the freehand technique and two guided surgery workflows, taking the initial digital planning as the reference in an in vitro experimental model. Materials and Methods: An in vitro experimental study was conducted with 24 implant placements distributed into three groups: freehand placement (FHI), guided surgery using a non-specific workflow (GS-NS), and guided surgery using a dental-specific workflow (GS-DS), with eight implants per group. CBCT scans were used for three-dimensional segmentation, virtual planning, fabrication of 3D-printed models, design of restrictive surgical guides, and implant placement. Results: The freehand technique showed the highest mean deviations for all three variables evaluated. Coronal deviation was 1.738 ± 0.342 mm for FHI, 0.375 ± 0.225 mm for GS-NS, and 0.400 ± 0.193 mm for GS-DS. Apical deviation was 1.812 ± 0.344 mm, 0.575 ± 0.249 mm, and 0.537 ± 0.220 mm, respectively. Angular deviation was 8.691 ± 1.522° for FHI, 3.038 ± 0.501° for GS-NS, and 3.100 ± 0.441° for GS-DS. Conclusions: Guided surgery reduced both linear and angular deviations compared with freehand implant placement. However, under the experimental conditions evaluated, the dental-specific workflow did not demonstrate statistically significant superiority over the non-specific workflow.

(Universidad Santo Tomás, 2026-08-14) Bustos Gómez, Raul Sebastian; Trillos Celis, Javier Humberto; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000633275; https://scholar.google.com/citations?user=DmTRplsAAAAJ&hl=es&oi=ao; https://scienti.minciencias.gov.co/gruplac/jsp/visualiza/visualizagr.jsp?nro=00000000013054; https://orcid.org/0000-0001-9432-6500
This article analyzes the business and industrial environment of Ciudad Obregón, Sonora, Mexico, through the lens of an international academic visit. The research examines how regional productive and logistical dynamics operate within global value chains and in relation to international standards. The main objective was to examine the characteristics of the observed business environment and relate them to the theoretical foundations of International Business. A qualitative and descriptive methodological approach was employed, utilizing direct observation in various industrial sectors, supplemented by field notes and reflective analysis. The findings highlight a high level of process standardization, operational discipline, and coordination between production and logistics, emphasizing the importance of quality control and organizational efficiency. Additionally, the experience revealed the relevance of human capital and structured cultures in supporting industrial performance. The study concludes that academic visits constitute a valuable methodological tool for strengthening practical understanding of business environments and bridging the gap between academic training and real-world industrial dynamics, providing students with essential analytical competencies for the global market.

Informe de prácticas empresariales en Econova Meta
(Universidad Santo Tomás, 2026-08-06) Vergara Valencia, Karol Yendrishka; Hernández Bustos, Helen Natalia; Sosa Quintero, Carol Dayana; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000005773; https://scholar.google.es/citations?hl=es&user=5QpJzi4AAAAJ; https://orcid.org/0000-0002-7343-6679
This professional internship was carried out at the Innovation Center of the Eastern Plains Region – Econova Meta, an initiative led by Santo Tomás University and Ecopetrol aimed at strengthening innovation, entrepreneurship, and business development processes in the Meta region of Colombia. The main objective was to contribute to the institutional strengthening of Econova Meta and to design a business support methodology focused on marketing, called MarketLAB. The research was developed under a mixed-method approach with a descriptive scope, using participant observation, semi-structured interviews, document review, and performance indicator analysis. As a result, several institutional communication strategies were designed and implemented, including graphic materials, audiovisual content, visual identity resources, and support tools for events and institutional activities, contributing to brand positioning within the regional Science, Technology, and Innovation ecosystem. Additionally, the MarketLAB methodology was structured and tested through a pilot implementation with a company from the fashion sector. This process validated a business support model based on business diagnosis, market analysis, solution co-creation, strategy implementation, and results evaluation. Findings showed improvements in digital visibility, organic positioning, communication consistency, and strategic content management. Finally, the internship demonstrated that institutional communication strengthening and specialized marketing support are valuable tools for enhancing competitiveness, sustainability, and innovation among entrepreneurs and organizations within the regional ecosystem.
