In-vitro fatigue and fracture performance of three different ferrulized implant connections used in fixed prosthesis
Background/purpose: The aim of the present in vitro study was to evaluate fatigue resistance of dental fixtures in three different types of fixture/abutment finishing line. Materials and methods: Transmucosal dental implants, with or without ferrulized neck, underwent fatigue tests (static and dynamic load) using the following standard protocol: UNI EN ISO 14801:2016. Two types of loading devices (screw- or cement-retained restoration) were also tested, and fatigue cycle tests were run to failure. Data of static and dynamic load tests were analyzed by proper statistical methods. Results: Following standard protocol for fatigue testing, the ILC type (Implant Level with ferrulized neck and ce…
Radiological Outcomes of Bone-Level and Tissue-Level Dental Implants: Systematic Review
Purpose: to assess any differences on marginal bone loss between bone-level or tissue-level dental implants through a review of literature until September 2019. Materials and methods: MEDLINE, Embase and other database were searched by two independent authors. The search was limited to articles in English. Results: The search provided 1028 records and, after removing the duplicates through titles and abstracts screening, 45 full-text articles were assessed for eligibility. For qualitative analysis 20 articles were included, 17 articles of them for quantitative analysis. A total of 1161 patients (mean age 54,4 years) and 2933 implants were observed, 1427 (Tissue-level) and 1506 (Bone-level).…
The effectiveness of the information‐motivation model and domestic brushing with a hypochlorite‐based formula on peri‐implant mucositis: A randomized clinical study
OBJECTIVE Management of mucositis is essential for the long-term maintenance of dental implants. This study determined the efficacy, in terms of clinical parameters, of an adjunctive domiciliary agent paired with non-surgical periodontal therapy (NSPT) for patients with peri-implant mucositis. MATERIALS AND METHODS Patients involved in a periodontal maintenance program were randomly distributed to the domestic use of a chlorhexidine toothpaste and mouthwash (control) or a hypochlorite-based formula brushing solution (test) after diagnosis of peri-implant mucositis. A modified approach towards NSPTwas performed after 10 days of domestic use of the assigned maintenance product in both groups.…
Oral health-related quality of life and clinical outcomes of immediately or delayed loaded implants in the rehabilitation of edentulous jaws: A retrospective comparative study
Background Patient-centered outcomes are being given great attention by the dental scientific community. The Oral Health Impact Profile -14 questionnaire (OHIP-14) has been introduced to address patients' success criteria when describing the impact of oral rehabilitations on quality of life (OHrQoL). Methods Thirty-five patients wearing a full-arch implant-prosthesis being in place between 4 and 6 years before this analysis were considered eligible and then enrolled in the present retrospective study. According to their prosthetic anamnesis, two groups were defined: delayed loading group (IL-group) and immediate loading group (IL-group). At the moment of analysis, clinical and radiographic …
Local Formula with Mucoadhesive Property: A Randomized Clinical Trial of a Therapeutic Agent for the Treatment of Oral Aphthous Ulcers
Background Recurrent or occasional aphthous lesions represent a painful oral condition with high prevalence. Since the etiology is still unclear and most likely related to a dysfunction in the local immune system, several treatment strategies have been proposed, including systemic agents, local agents, and laser therapy, to reduce the pain and discomfort for the patient without acting on the causes. Materials and methods The purpose of the present randomized study was to assess the clinical efficacy of a new topical gel with mucoadhesive property to reduce the pain and the dimension of the aphthosis lesions. Fifty patients presenting at least one minor ulcer were randomized to a control gro…
In-Vitro Investigation of Fatigue and Fracture Behavior of Transmucosal versus Submerged Bone Level Implants Used in Fixed Prosthesis
Background: The present in vitro study aimed to investigate the fatigue performance of different dental fixtures in two different emergence profiles. Biological failures are frequently reported because the problem canonly be solved by replacing a failing implant with a new one. Clinicians addressed minor mechanical failures, such as bending, loosening or the fracture of screws, abutment, or the entire prosthesis, by simply replacing or fixing them. Methods: Transmucosal and submerged bone-level dental implants underwent fatigue strength tests (statical and dynamical performance) by a standardized test: UNI EN ISO 14801:2016. Two types of emergence profiles (Premium sub-crestal straight impl…
The Efficacy of Powered Oscillating Heads vs. Powered Sonic Action Heads Toothbrushes to Maintain Periodontal and Peri-Implant Health: A Narrative Review.
Objectives: To compare the efficacy of rotating-oscillating heads (ORHs) VS sonic action heads (SAHs) powered toothbrushes on plaque accumulation and gingival inflammation. Methods: An electronic (MEDLINE, Embase, Inspec, PQ SciTech and BIOSIS) and a complementary manual search were made to detect eligible studies. RCTs meeting the following criteria were included: final timepoint longer than 15 days; year of publication after 2000; patients without orthodontic appliances or severe systemic/psychiatric diseases. Studies comparing two or more different types of sonic/roto-oscillating toothbrushes were excluded. Selection of articles, extraction of data, and assessment of quality were made in…
Comparación de implantes transmucosos con cuello convergente frente a implantes sin cuello
En los últimos años, se han realizado varios estudios clínicos y revisiones sistemáticas para comparar los implantes “Bone-level” (BL) y “Tissue-level”(TL). Aunque los resultados de la última revisión sistemática realizada al principio de este trabajo de tesis que analizaba las diferencias entre los implantes dentales BL y TL en sitios únicos o múltiples no mostraban diferencias en términos clínicos y radiográficos, probablemente debido al uso del “Platform-switching” en la implantología moderna. Por otro lado, hay muy pocos estudios en la literatura que comparen los implantes BL y TL en términos de propiedades mecánicas, especialmente los implantes TL con cuellos convergentes, que son cada…
