La guarigione della ferita chirurgica nel cavo orale

2021

OBJECTIVES The aim of the study is to describe the physiological mechanism of healing of the surgical wound of the oral cavity and to present the systemic and local factors that can influence it. MATERIALS AND METHODS Hemostasis starts with the activation of the platelets and the coagulation cascade which carry out the vascular constriction and the formation of the fibrin clot which stops the blood loss and provides a temporary scaffold for the migration and anchoring of the cells that will reach the subsequent stages. The clot and surrounding injured tissue begin to release pro-inflammatory cytokines and growth factors such as tranforming growth factor-β (TGF-β), platelet-derived growth fa…

Three single loops enhance the biomechanical behavior of the transtibial pull-out technique for posterior meniscal root repair

2017

Purpose: To investigate the effect of applying an additional suture to enhance the biomechanical behavior of the suture–meniscus construct used during the transtibial pull- out repair technique. Methods: A total of 20 fresh-frozen porcine tibiae with intact medial menisci were used. In one half of all speci- mens (N = 10), two non-absorbable sutures were passed directly over the meniscal root from the tibia side of the meniscus to the femoral side (2SS). In other ten specimens, three sutures were passed over the meniscal root (3SS). All specimens were subjected to cyclic loading followed by load-to-failure testing. Displacement of the construct was recorded at 100, 500, and 1000 cycles. Fur…

Predicting patient compliance in orthodontic treatment

2000

Abstract This article reviews the current knowledge regarding prediction of patientcompliance during orthodontic treatment. Relevant literature dealing with this and other related aspects of patient compliance is discussed, and an attempt is made to structure and summarize available information. The multifacetted nature of this issue is emphasized, existing controversies highlighted, and where appropriate, practical suggestions are made.

Photobiomodulation and myofascial temporomandibular disorder: Systematic review and meta-analysis followed by cost-effectiveness analysis

2021

Background Photobiomodulation (PBM) is a non-invasive and non-pharmacological treatment, which, has shown beneficial results in the treatment of temporomandibular disorders (TMD) related pain. This systematic review and meta-analysis study aimed to evaluate the efficacy of photobiomodulation in the treatment of myofascial pain associated with (TMD by analyzing randomized clinical trials published from 2007 to February 2019. The secondary objective of the study was to perform a cost-effectiveness analysis of TMD treatment with photobiomodulation in patients with myofascial pain. Material and methods International databases were used: Pubmed, Medline and Web of Science; the initial search rai…

Effects of mandibular advancement surgery on the temporomandibular joint and muscular and articular adaptive changes--a systematic review.

2016

The objective of this study was to assess the anatomical changes to the condyle and articular disc following mandibular advancement surgery, the adaptation of the masticatory muscles, and the improvement or worsening of temporomandibular disorders (TMD) in patients with pre-existing disorders and those who developed them following surgery. Four databases were searched systematically: PubMed, Scopus, Embase, and Cochrane Library. Of the 544 articles initially selected, 219 were duplicates and a further 165 were excluded on the basis of their titles and abstracts. On reading the full text, 89 were excluded because they were of no interest and 43 because they did not meet the inclusion criteri…

Temporomandibular joint arthrocentesis guided by ultrasonography: An anatomical study

2021

The temporomandibular joint (TMJ) arthrocentesis is a common procedure in maxillofacial surgery departments for the treatment of TMJ dysfunction. The use of ultrasonography in this area is rare, and in the vast majority of cases only as a diagnostic, and non-therapeutic use. Through this study we propose the equipment and ultrasound parameters necessary to obtain detailed and practical images when using ultrasonography as a therapeutic guide in arthrocentesis of TMJ. In addition, we provide data regarding the placement and working angulations of both the ultrasound probe and the needle that are ideal for facilitating image-guided puncture. It is a simple technique, with a relatively short l…

Surgical and orthodontic rapid palatal expansion in adults using a modified palatal partial osteotomy technique (ppot): Technique description and cli…

2020

Transversal hypoplasia of the upper maxilla is a frequent condition between malocclusions. The rapid maxillary expansion (RME) is an already consolidated technique for these types of defects. This case report analyzes the outcome of a novel surgical technique that we named TOPP (Partial Palatal osteotomy technique) aiming to provide scientifically proven data over the percentage of relapse and the long-term stability of this type of surgical assisted palatal expansion. A 24 year old male patient with a hyperdivergent class III, presenting the absence of 1.1 due to a teenage trauma and a transversal contraction of the upper arch was selected for the surgery. The mucoperiosteal flap was perfo…

Marsupialization of a large dentigerous cyst in the mandible with orthodontic extrusion of three impacted teeth. A case report

2017

The dentigerous cyst (DC) is the most common type of developmental odontogenic cyst. It is usually asymptomatic and associated with the crown of an unerupted or impacted tooth. However, after a long duration, it is likely to cause significant bone resorption, cortical expansion, and tooth displacement. This report presents a large infected DC in the mandible of a 12-year-old female patient. The DC was located inferior to badly decayed primary molars and surrounded three impacted permanent teeth: canine, first premolar, which had a dilacerated root, and second premolar. The DC was treated successfully by marsupialization and extrusion of the impacted teeth. In conclusion, the combination of …

Post-orthodontic position of lower incisors and gingival recession: A retrospective study

2017

Background To evaluate if changes in lower incisor position following orthodontic treatment are correlated with development of gingival recessions. Material and methods Pre- and post-treatment digital models and lateral cephalograms of 22 subjects were collected retrospectively. The clinical crown length, gingival scallop, and papilla height of the central lower incisor were measured along with the cephalometric incisor's inclination, the distance from the mandibular plane, and the distance between the Infradentale and Menton points. Statistical correlations between gingival and cephalometric variables were studied. In addition, two groups were defined based on the post-treatment incisor in…
