Palatal graft harvesting techniques: A narrative review
No full textOBJECTIVES According to the American Acade my of Periodontology, soft tissue grafting consists of harvesting soft tissue that is completely detached from the donor site and placed in a properly prepared recipient bed. The harvesting of soft tissue from the palate is a technique used in periodontics for over fifty years and still in continuous evolution. From free gingival grafting to bilaminar techniques with connective tissue only or free gingival grafts disepithelized extra-orally, several techniques have been proposed over the years, some of which are now part of today’s periodontal plastic surgery. These techniques are designed to increase periodontal soft tissue thickness, restore a proper keratinized tissue width, correct muco-gingival deformities, improve aesthetics, allow correction of peri-implant de hiscences, soft tissue augmenta tion and ridge preservation, in or der to limit post-extraction bone crest alteration in aesthetically rel evant areas. MATERIALS AND METHODS This narrative review considers the main techniques of soft tissue harvesting from the palate as described in the literature, from the trap-door proposed by Edel in 1974 to the free gingival graft disepithelialized extra-orally proposed by Zucchelli, through a series of single incision techniques introduced over the years. The examination of the grafting techniques is followed by the analysis of the donor area (lateral palate or maxillary tuber) in terms of tissue quality, composition and thickness, difficulties and complications of the surgery. Wound healing and post-operative discomfort are also explored, evaluating the main differences between techniques involving an epi thelial-connective graft and techniques involving only a connective graft. In particular, the use of donor site protectors, such as cyanoacrylate adhesives and PRF (Platelet-Rich Fibrin), is considered. Finally, possible complications are considered − from intra-operative and post-operative bleeding, treatable by compression with wet gauze and tranexamic acid − to less frequent complications such as flap laceration and donor site infection. RESULTS AND CONCLUSIONS The most indicated technique seems to be the harvesting of an extra-orally disepithelized free gingival graft. This bilaminar technique, besides having shown the best clinical results, is also easier to perform, in a reduced operative time and with a lower risk of damaging vascular structures; moreover, the graft composition is richer in connective tissue, without contamination of adipose or glan dular tissue of lower quality. On the other hand, its harvesting technique implies second inten tion healing at the donor site, which may be less comfortable for the patient, but without increasing post-operative pain. In addition, the use of a donor site protection appears to further reduce possibile post-operative patient morbidity. CLINICAL SIGNIFICANCE The use of an extra-orally disepithelized free gingival graft as part of a bilaminar technique can be considered the gold standard among the soft tissue augmentation techniques, possibly accompanied by the use of donor site protections
Implant-Supported Prosthetic Therapy of an Edentulous Patient: Clinical and Technical Aspects
No full textThe purpose of this article is to show how to implement an implant-supported prosthetic overdenture using a digital workflow. Esthetic previewing using a specific software, guided-surgery, construction of the prosthesis, and the esthetic finalization are described in this article. Patients suffering from severe loss of bone and soft tissue volume could benefit from the construction of an overdenture prosthesis as a feasible therapeutic choice for functional and esthetic issues of the patient
“Movement patterns and cognitive- adaptive functions. An exploratory evaluation in the early years of primary school”
No full textThis exploratory study investigates the relationship between movement patterns and cognitive-adaptive functions in the early years of primary school. Based on the assumption that motor experiences are essential for children’s overall development, the research involved a sample of 263 pupils (M=124; F=139) attending the first and second grades of primary school, assessed through the APCM-2 test for praxic abilities and motor coordination. The findings reveal slight difficulties in motor planning and sequencing processes, as well as a partial acquisition of basic movement patterns, particularly in activities requiring integration between balance and dynamic coordination. The results suggest the need to promote targeted educational interventions within Physical Education activities to enhance motor and cognitive development from the early school years. These findings highlight the importance of an early and systematic approach to motor education to foster the harmonious and integrated development of children’s skill
SELF-EFFICACY AND MOTOR PERFORMANCE: THE IMPACT OF MOTOR-EXPRESSIVE ACTIVITIES IN PRIMARY SCHOOL
No full textThe recent scientific contributions of neuro-pedagogy map learning processes in the light of a
multi-perspective vision that, recognising the existence of a circular dialogue between cognitive,
experiential and bodily narrative dimensions (Damasio, 1995; Gallese et al., 2006; Glenberg, 2008;
Barsalou, 2010; Caruana & Borghi, 2016), return centrality to the body in action in terms of increasing
perceived self-efficacy and intrinsic motivation (Brambilla et al., 2010; Biddle et al., 2019; Errisuriz et al.,
2018). The need to acquire a holistic view of the educational process in the context of Physical Educational
practices and the search for methodological practices and variants that can become the crossroads of
interdisciplinary dialogues (Colella et al., 2020), meet the assumption that the sense of self-efficacy
influences both motivation and behaviour, as well as the ability to cope with challenges and to adopt
proactive attitudes (Bandura, 1997; Schunk & Pajares, 2009). This study investigates, with reference to age
group, gender and learning context (school/dance), the relationship between self-efficacy and motor
performance in developmental age. The aim is to consider how and according to which theoretical and
practical assumptions motor-expressive activities can fit into first-cycle schools, in order to effectively act
in the horizontal and vertical curriculum, by enhancing the development of fields of experience and
competences. The study involved a convenience sample of 248 children between the ages of 8 and 10,
(M=75; F=174), selected by non-probabilistic sampling. The first group was provided with experiential
paths of expressive movement and yoga, and a second group was offered traditional Physical Education
practices. The results, investigated through the administration of the self-report PSP_C (Children's
Self-Efficacy Scale) (Colella et al., 2008), show that a correct disposition of the body's musculoskeletal
structures in relation to the force of gravity and the efficient and enunciative movements enabled by the
prompting of the proprioceptive mechanisms of the body scheme in stasis and dynamics, promoted an
increase in perceived self-efficacy in the group that practiced motor/expressive activities. This confirms
that self-efficacy develops through direct experience and meaningful learning and could be a determining
factor for personal growth and general well-being (Zimmerman, Cleary 2006). The educational approach
declined in movement-expressive practices (Pallonetto, 2023), experiential anatomy (Olsen, Tolja, 1994),
ideokinesis (Bernard et al. 2021), yoga (Bazzano et al. 2018) and educational dance (Palumbo, 2024), implemented the dimension of feeling and body awareness by opening the channels of somatic memory and sense-motor intelligence

ANALYSES OF ROMAN WALL PAINTINGS , BASILICA OF SANTA MARIA MAGGIORE, TRENTO.
No full textQuesto studio mira alla caratterizzazione chimico-fisica dei numerosi frammenti di pittura romana rinvenuti durante lo scavo archeologico della Basilica di Santa Maria Maggiore a Trento.L’obiettivo è quello di confermare la destinazione d’uso delle strutture di epoca romana riportate in luce, identificate dagli archeologi con i resti di un impianto termale pubblico risalente al I secolo d.C., attraverso l’identificazione dei pigmenti e delle tecniche pittoriche usate per la loro decorazione. Le principali tecniche analitiche utilizzate per determinare la composizione dei campioni sono state la spettrometria infrarossa a trasformata di Fourier (FT-IR), la microscopia Raman e la fluorescenza a raggi X (XRF)
