- A 3D digital analysis of the hard palate wound healing after free gingival graft harvestPublication . Marques, Tiago; Ramos, Sara; Santos, Nuno Bernardo Malta dos; Borges, Tiago; Montero, Javier; Correia, André; Fernandes, Gustavo Vicentis de OliveiraPurpose: Within this context, this pilot study aimed to evaluate the healing dynamics process of the hard palate after free gingival graft harvesting in the short term (3 months), utilizing digital imaging technology and tridimensional analysis software. Furthermore, assessing the results found to verify the existence of a relationship between gender or age with tissue loss. Materials and Methods: For connective-tissue harvesting, fifteen patients with gingival recessions type (RT) 1 and RT2 were selected. On the surgery day (before the procedure) and after three months, palatal impressions were taken in all patients, and cast models were done for posterior model scanning. The following variables were analyzed: mean thickness alterations (x¯ TA), maximum thickness loss (MTL), mean maximum thickness loss (x¯ MTL), and volume alterations (VA). A descriptive and bivariate analysis of the data was done. The data were submitted for statistical evaluation and were significant if p < 0.05. Results: Fifteen patients were analyzed, 11 females (73.3%) and four males (26.7%). The patients’ average age was 28 ± 8.52 years (ranging between 16 and 48 years old). The palatal wound region’s mean thickness and volume changes were −0.26 mm (±0.31) and 46.99 mm3 (±47.47 mm3) at three months. There was no statistically significant result correlating age/gender with any variable evaluated. Conclusions: Connective tissue graft harvesting promoted changes with a standard volume and thickness loss of palatal soft tissue. A 3D digital evaluation was a non-invasive method with a reproducible technique for measuring thickness or volume after connective tissue is collected. There was no relationship between age/gender and any variables analyzed.
- Dentists’ perceptions and usability testing of the Implant Disease Risk Assessment IDRA, a tool for preventing peri-implant disease: a qualitative studyPublication . Bornes, Rita; Montero, Javier; Ferreira, Ana; Rosa, Nuno; Correia, AndréIntroduction: we aimed to explore dentists’ perceptions toward the implementation of a dental informatics risk assessment tool which estimates the risk for a patient to develop peri-implantitis. Materials and Methods: the Implant Disease Risk Assessment Tool (IDRA) was presented to a convenience sample of seven dentists working in a university clinic, whom were asked to use IDRA with the information of three clinical cases whilst thinking aloud and then fill the System Usability Scale (SUS). A semi-structured interview technique was used with audio record to allow free expression of participants’ perceptions related to the IDRA. The interviews information was categorized and analyzed by the authors. Results: to our knowledge, this is the first study conducted to develop a qualitative usability test of IDRA, evaluating the effectiveness, efficiency, and users’ satisfaction. There were more variations in responses the greater the degree of complexity of the clinical case. Generally, the participants classified the tool as good, getting usability values of 77,2 (SD 19,8) and learnability 73,2 (SD 24,5). Conclusion: four additional factors should be considered to improve IDRA tool: 1) considering the relation between contour angle and peri‐implant tissue height; 2) automatic periodontal classification in the IDRA tool after completing the periodontogram in the clinical software; 3) presentation of a flow chart to assist therapeutic decisions alongside the final score defined by the IDRA tool; 4) integrating of precision tests such as Implantsafe® DR (dentognostics gmbh, Jena) and Oralyzer®(dentognostics gmbh, Jena). Clinical Significance: etiology and pathogenesis of peri-implant diseases is multifactorial. These tools must follow a natural integration to be easily applied in a clinical setting. It is important to study their usability from the clinicians’ point of view, evaluating the effectiveness, efficiency, and users’ satisfaction.
- A different approach to analyzing the surface roughness of prosthetic dental acrylic resinsPublication . Quezada, Margarida Martins; Fernandes, Carlos; Montero, Javier; Correia, André; Salgado, Helena; Fonseca, Patrícia(1) Introduction: Apart from the polishing method, conventional or mechanized, the arithmetic mean roughness (Ra) is the most common metric to evaluate the surface roughness of denture base acrylic resins. An overview of the constraints related to this roughness parameter is highlighted in this study. This research introduces new parameters for accessing a functional analysis of surface roughness. (2) Materials and Methods: Five samples of CAD/CAM 3D-printed acrylic resins were prepared. Two polishing techniques, manual and mechanical, were applied. Surface roughness parameters were extracted from a profilometer reading: arithmetic mean height (Ra and Pa), skewness (Rsk and Psk), and kurtosis (Rku and Pku). (3) Results: Significant differences (p < 0.001) were found in the Ra distribution among the study samples, in contrast with the lack of significance in Pa values. Surface roughness parameters revealed an increased coefficient of variance (CV) value due to mechanized polishing across the specimens analyzed. Skewness and kurtosis indicate a more pronounced distribution with the manual polishing technique. (4) Conclusion: This preliminary study exhibits the influence of different polishing protocols on surface roughness parameters. The primary profile, skewness, and kurtosis should be assessed for the surface characterization of acrylic resins.
- Effect of customized healing abutments on the peri-implant linear and volumetric tissue changes at maxillary immediate implant sites: a 1-year prospective randomized clinical trialPublication . Fernandes, Danilo; Nunes, Sílvia; López-Castro, Gonzalo; Marques, Tiago; Montero, Javier; Borges, TiagoBackground: Immediate implant placement (IIP) associated with the use of bone substitutes and collagen matrices (CM) seems to reduce the amount of resorption at peri-implant areas. Recently, customized healing abutments (CA) appeared as another solution in order to seal the socket and preserve the original soft tissue contour. Purpose: To evaluate peri-implant tissues dimensional changes after using customized healing abutments compared with the use of xenogeneic collagen matrices as socket sealing options in flapless maxillary immediate implant placement. Material and methods: The present study was designed as a prospective, randomized, controlled clinical trial. Patients were allocated into two groups depending on the socket sealing option: in the CM group a collagen matrix was used and in the CA group a customized abutment. Digital impressions were taken prior to extraction, 1, 4, and 12 months after implant insertion and the digital files allowed to evaluate linear buccal changes (MBC) and the buccal volumetric variation (BVv) between the different time points at peri-implant tissue areas. Additionally, mucosa variation was computed assessing the papilla presence and the midfacial mucosa height. Statistical significance was set at 0.05. Results: Twenty-eight patients were observed during a 12-month period. Significant differences between mean values of BVv at the first month were observed at the CM and CA group (−9.75 ± 6.65% and −4.76 ± 5.29%, respectively) (p = 0.043). At the 1-year follow-up, no significant differences were found in terms of BVv between the two groups, although the thin bone phenotype (≤1 mm) significantly influenced the volumetric variations that occurred in each group. No significant differences were noticed in midfacial mucosa and papillae alteration between groups, after 1 year of treatment. Conclusion: Both treatment options are predictable solutions for socket sealing in IIP, although a higher volumetric variation can be expected in the presence of thin bone phenotypes.
- Oral health related quality of life in institutionalized elderly in ViseuPublication . Balula, Sandra; Silva, Ana Margarida; Couto, Patrícia; Figueiredo, Cristina; Correia, André; Veiga, Nélio Jorge; Montero, JavierBackground: Portugal has an increasingly aging population, due to the raise of average life expectancy and low birth rates. This situation constitutes a challenge for public health, particularly regarding oral health related quality of life. The objective of this study is to assess the impact of oral health on the quality of life of institutionalized elderly people in the district of Viseu, Portugal. Materials and methods: An observational descriptive cross-sectional study was designed, composed of a population of elderly residents in nursing homes in the district of Viseu. Data collection was accomplished by an application of a questionnaire to assess sociodemographic and oral health aspects, the GOHAI index and the OHIP-14 index. Results: The sample consisted of 529 institutionalized elderly aged 65 years or older. As for gender, 69.4% (n=367) are women and 30.6% (n=162) men. According to the GOHAI index, a considerable number of participants (41.5%) have a “moderate” self-perception of oral health. Regarding the OHIP-14 index, it appears that the impact of oral health on quality of life is low, since the average of the global OHIP-14 was 15 (0-56). “Physical pain” was the most affected dimension (2.70), while the dimension with the least impact was “Social limitation” (1.52). Conclusion: in this research, oral health related quality of life was considered reasonable. However, there are participants in whom the impact of oral health in the quality of life is significant. Therefore, it is important to continue to develop strategies and join efforts to improve oral health and, consequently, the systemic health and quality of life of institutionalized elderly.

- Peri-implant diseases diagnosis, prognosis and dental implant monitoring: a narrative review of novel strategies and clinical impactPublication . Bornes, Rita; Montero, Javier; Correia, André; Marques, Tiago; Rosa, NunoBACKGROUND: The diagnosis of peri-implantar and periodontal relies mainly on a set of clinical measures and the evaluation of radiographic images. However, these clinical settings alone are not sufficient to determine, much less predict, periimplant bone loss or future implant failure. Early diagnosis of periimplant diseases and its rate of progress may be possible through biomarkers assessment. Once identified, biomarkers of peri-implant and periodontal tissue destruction may alert the clinicians before clinical signs show up. Therefore, it is important to consider developing chair-side diagnostic tests with specificity for a particular biomarker, indicating the current activity of the disease. METHODS: A search strategy was created at Pubmed and Web of Science to answer the question: "How the molecular point-of-care tests currently available can help in the early detection of peri-implant diseases and throws light on improvements in point of care diagnostics devices?". RESULTS: The PerioSafe® PRO DRS (dentognostics GmbH, Jena) and ImplantSafe® DR (dentognostics GmbH, Jena ORALyzer® test kits, already used clinically, can be a helpful adjunct tool in enhancing the diagnosis and prognosis of periodontal/peri-implantar diseases. With the advances of sensor technology, the biosensors can perform daily monitoring of dental implants or periodontal diseases, making contributions to personal healthcare and improve the current status quo of health management and human health. CONCLUSIONS: Based on the findings, more emphasis is given to the role of biomarkers in diagnosing and monitoring periodontal and peri-implant diseases. By combining these strategies with traditional protocols, professionals could increase the accuracy of early detection of peri-implant and periodontal diseases, predicting disease progression, and monitoring of treatment outcomes.
- The effect of the interproximal creeping attachment in aesthetic site after root coverage surgery with VISTA technique - a case reportPublication . Marques, Tiago M.; Santos, Nuno B. M.; Montero, Javier; Correia, André; Fernandes, Gustavo V. O.Gingival recession is a common manifestation in most populations. The mechanism by which gingival recession occurs is not well understood, but it seems to be complex and multifactorial. The main etiological factors are the accumulation of dental plaque biofilm with the resulting inflammatory periodontal diseases and mechanical trauma due to faulty oral hygiene techniques, especially in thin biotypes. This case report describes the treatment of a vestibular recession associated with interdental bone loss, with the VISTA technique associated with a connective tissue graft. The case was evaluated at 3, 9 months and 48 months after the surgery clinically complete root coverage and increased thickness of keratinized tissue were achieved, and the interdental papilla was augmented improving the soft tissue quality for future orthodontic treatment. VISTA technique associated with a connective tissue graft to reconstruct vertically papilla is a promising alternative for minimally invasive treatment and stable after 4 years.
