    Orbitozygomatic fractures represent a complex surgical challenge. Given the urgent need for validated educational tools that surpass traditional learning models, this multicenter study developed and validated a novel synthetic advanced simulation model for the reconstruction of these fractures. The model integrates platinum-cured silicones and 3D-printed bony structures with prefabricated fractures, accurately replicating the anatomy and tactile properties of soft and hard tissues, including simulated herniation of orbital contents. To our knowledge, it is the only available synthetic model combining both tissue types for this training. Ten participants (faculty and residents) completed simulated procedures. Technical performance was assessed using a hand motion tracking system, the global OSATS (Objective Structured Assessment of Technical Skills) scale, and a task-specific error measurement (Specific Fault Measurement, SFM) scale. Statistically significant differences (p = 0.021) were observed in operative time and error count between novices and experts, confirming the model’s construct validity. Faculty completed the surgery in significantly less time (mean 18.16 min vs. 37.01 min for residents) and made fewer errors (mean 12.25 vs. 53.25). Face and content validity were strongly supported by participant surveys, with 100% stating they would use the simulator to practice before real surgery. A strong inverse correlation (r = –0.786, p = 0.021) between OSATS and SFM scores demonstrated concurrent validity. This model enables ethical, repeatable, and cost-effective training, supporting its implementation into surgical curricula to enhance competence and provide objective skill assessment in orbitozygomatic trauma surgery.

    Associations of number and position of tooth loss and quality of life in the Chilean population: a cross-sectional study
    (2025) Célis Sersen, Andrés; Celis Dooner, Jorge; Vargas Buratovic, Juan Pablo; Carrasco Mococain, Claudio; Mellado Torres, Beatriz; Moreno Ferrer, Francisco; Tagle, Elizabeth L.; Borroto, Duniel O.
    Background Multiple studies have demonstrated the association between Quality of Life (QoL) and the prevalence of caries, periodontitis, and tooth loss. However, the role of the position and location of tooth loss in impacting QoL remains unclear. Aim To evaluate the association of tooth loss, including anterior losses, with Health-Related Quality of Life (HRQoL) and Oral Health-Related Quality of Life (OHRQoL) in Chileans aged 15 years and older who participated in the ENS 2016–2017. Methods In this cross-sectional study we included 5473 individuals enrolled in the last Chilean National Health Survey (ENS 2016–2017). HRQoL was measured using the EQ-5D questionnaire, while OHRQoL was assessed through a general question (GQ/ENS) and five specific questions (SQ/ENS). An analysis of variance test was performed to determine how difference or variation in the number(s) of teeth affected their HRQoL. Odds ratios with corresponding 95% confidence intervals were calculated using multinomial logistic regression to determine how and to what degree anterior tooth loss was associated both with HRQOL and OHRQOL in the study sample. Results The number of remaining teeth was significantly higher in the ‘No problems’ group across all EQ-5D dimensions, except Anxiety/Depression. The largest difference was in Self-care, where ‘No problems’ had a mean of 20.18 compared to 6.43 teeth in the ‘Problematic’ group. Anxiety/Depression showed higher odds of ‘Some problems’ with upper anterior tooth loss, while ‘Usual Activities’ showed higher odds of ‘problematic’ with lower anterior tooth loss. Participants with an ‘Excellent’ OHRQoL perception had a mean of 24.32 teeth. Also, upper and lower anterior tooth loss increased the odds of OHRQoL self-perception. Conclusions Tooth loss was associated with lower HRQoL and OHRQoL in some groups, with more remaining teeth associated with better outcomes, while anterior tooth loss was- linked to worse self-perceived oral health.

    Determinants of anterior tooth loss in Chilean adults: data from the Chilean National Health Survey 2016-2017.
    (F D I WORLD DENTAL PRESS LTD, 2020) Berrios Vigneaux, Rodrigo; Vargas Buratovic, Juan Pablo; Moreno, Florencia; Mellado Torres, Beatriz; Cantarutti Martinez, Cynthia; Padilla Perez, Oslando; Margozzini Maira, Paula; Ortuno Borroto, Duniel R.
    Objective: To describe prevalence of anterior tooth loss and its determinants among Chilean people aged over 15 years. Methods: Crosssectional study, using the sampling frame of the Chilean National Health Survey 2016-2017 (n=5473 participants). Multivariate logistic regressions were performed to obtain the prevalence and odds ratio (OR) for anterior tooth loss using a complex sampling method. We described anterior tooth loss affecting each jaw according to sex, age, educational level, urban/rural residence and having health insurance. Results: The odds of anterior tooth loss were 7.11 (95%CI: 4.57 - 10.78) and 4.84 (95%CI: 3.02 - 7.72) times higher for low-educated subjects compared to those with more educational, for the upper and lower jaw respectively. Also, the odds of anterior tooth loss for the upper jaw was 1.34 (CI 95%: 1.07 - 1.66) times higher in women, whereas for the lower jaw, no significant differences by sex were found (p-value 0.14). Adults having only the National Health Fund B insurance (FONASA B) had odds of losing one or more anterior teeth 2.43 (CI 95%: 1.34 - 4.39) times higher in the upper jaw and 2.08 (CI 95%: 1.03 - 4.20) in the lower jaw compared with those having Health Insurance Institutions (ISAPREs). Conclusion: Our study showed for the first time that anterior tooth loss is a widespread condition in Chile, with marked inequities by sex, age, educational level, and geographical area. People in the public health insurance system have a higher odds of anterior tooth loss.

    Impact of the national program More Smiles for Chile on women's quality of life
    (2021) Ortuno Borroto, Duniel R.; Ahumada Salinas, Alexis; Vargas Buratovic, Juan Pablo; Carrasco Mococain, Claudio; Moreno Ferrer, Alonso; Prado Vera, Sebastian
    More Smiles for Chile (MSCH) is a national program that helps women to access comprehensive dental care. Objedive: To assess the changes in oral health related quality of life (OHRQoL) of women attending the MSCH program. Methods: Uncontrolled cohort study including all women registered in the National Health Fund (FONASA), who were at least 20 years old and received dental treatment in the MSCH program during 2016 or 2017 and completed OHIP-7 pre and post treatment. The median was used to describe central tendency and interquartile range to evaluate dispersion. Results: The study included 11782 women in 2016 and 16533 in 2017. The median OHIP-7 scores pre and post treatment were 8 and 6 respectively. Reductions were significant (p<0.001) for the total score and OHIP-7 dimensions, especially physical pain, physiological discomfort and psychological disability. Conclusion: The OHRQoL of women improved after treatment in the Chilean MSCH program.
