Descriptive retrospective study analyzing relevant factors related to dental implant failure
2019
Background The objective of this retrospective descriptive study was to analyze the characteristics of incident reports provided by dentists while using a specific brand of dental implants. Material and Methods The study was carried out in collaboration with Oxtein Iberia S.L.®, with the company providing access to the incident database in order to evaluate the characteristics of incidents from January 2014 to December 2017 (a total of 917 over four years). The data sheet recorded different variables during each of the stages of implant treatment, from initial implant placement to subsequent prosthetic rehabilitation. These variables included age, sex, systemic pathologies, smoking habits, …
Anxiety sensitivity as predictor of pain in patients undergoing restorative dental procedures
2006
Abstract – Objectives: The personality disposition to anxiety sensitivity refers to beliefs about negative consequences of bodily arousal. The concept has recently been successfully applied in research on chronic pain conditions. The present study investigated whether anxiety sensitivity interacts with dental fear to increase expected and experienced pain during routine dental treatment. Methods: Subjects were 97 patients undergoing dental procedures of excavation and filling. Anxiety dispositions were measured by the Anxiety Sensitivity Index and the Dental Anxiety Scale. Expected and experienced pain were assessed by affective and sensory verbal descriptor scales and a numerical rating…
Implant treatment in atrophic posterior mandibles: Vertical regeneration with block bone grafts versus implants with 5.5-mm intrabony length
2014
Purpose: To retrospectively compare the outcomes of implants placed in posterior mandibles vertically regenerated with onlay autogenous block bone grafts and short dental implants. Materials and Methods: Consecutive patients with vertical bone atrophy in edentulous mandibular posterior regions (7 to 8 mm of bone above the inferior alveolar nerve) were treated with either implants placed in regenerated bone using autologous block bone grafts (group 1) or short implants (with 5.5-mm intrabony length) in native bone (group 2) between 2005 and 2010 and followed for 12 months after loading. The procedure used was the established treatment protocol for this type of patient at the Oral Surgery Uni…
Inflammatory implant periapical lesion: etiology, diagnosis, and treatment--presentation of 7 cases.
2008
Purpose To investigate implant periapical lesions, and to describe their treatment. The hypothesis of this evaluation is that implant periapical lesions are disorders of the area surrounding the apex of a dental implant, and that their etiology can be multifactorial (ie, vascular impairment, vascular ischemia, overheating of bone during drilling, and implant surface contamination). The diagnosis is based on the clinical manifestations and x-ray findings. The x-ray findings usually involve a periapical radiotransparency. Materials and Methods Seven patients with implant periapical lesions (3 in the upper jaw, and 4 in the mandible) after implant placement are described. All patients reported…
Lichenoid lesions of the upper lip: A retrospective study of 24 cases.
2017
Background Lichenoid lesions of the upper labial mucosa, without other oral or extraoral manifestations seem to be rare. The clinicopathologic features of 24 such cases are presented and the pertinent literature is reviewed. Material and Methods 24 Caucasian patients that clinically presented lichenoid features on the upper labial mucosa, with or without lichenoid lesions on the adjacent gingiva, were included in the study. Clinical features were extracted from the patients’ records, while dental plaque/calculus accumulation and composite resin restorations of the adjacent teeth were recorded. Four cases where an incisional biopsy was performed were further evaluated. Results There were 8 m…
Nanocrystalline Hydroxyapatite-Based Material Already Contributes to Implant Stability After 3 Months: A Clinical and Radiologic 3-Year Follow-up Inv…
2014
The present study reports on a 3-year clinical and radiologic follow-up investigation of dental implants placed 3 and 6 months after sinus augmentation in 14 patients. Augmentation was performed with a synthetic bone substitute material composed of nanocrystalline hydroxyapatite. The aim of the study was to determine how the integration period of the bone substitute material, that is, 3 months or 6 months, influences implant integration within the patient's upper jaw. Therefore, the following clinical and radiologic parameters were investigated: implant being in situ; Periotest value; and presence of peri-implant osteolysis, bleeding on probing, plaque, and soft tissue recession around the …
An up to 7-Year Retrospective Analysis of Biologic and Technical Complication With the All-on-4 Concept
2016
The aim of this study was to evaluate retrospectively biologic and technical complications as well as clinical and radiographic outcomes of patients treated with 4 implants according to the All-on-4 protocol and followed up to 7 years of function. Data from 56 consecutive patients presenting complete edentulous jaw, aged 18 years or older, treated between January 2008 and December 2013, were evaluated. The outcomes were implant and prosthetic survival and success rates, any complications, and marginal bone loss (MBL). Two-hundred twenty-four implants were placed in 56 patients. During the entire follow-up, 1 maxillary implant but no prosthesis failed during the healing process. Fourteen pat…
Oral rehabilitation with dental implants in patients with recessive dystrophic epidermolysis bullosa : a retrospective study with 2-15 years of follo…
2019
Background Epidermolysis bullosa (EB) comprises a group of hereditary disorders characterized by mechanical fragility of the skin and mucous membranes, with the development of blisters and vesicles in response to minimum tissue friction. Recessive dystrophic epidermolysis bullosa (RDEB) with generalized involvement is the most common subtype in the oral cavity. The present study was carried out to investigate dental implant survival, peri-implant tissue condition, patient satisfaction, and the impact of treatment upon the quality of life of patients with RDEB rehabilitated with implants and full-arch implant-supported prostheses. Material and Methods Thirteen patients with RDEB underwent de…
Scratches Removal in Digitised Aerial Photos Concerning Sicilian Territory
2007
In this paper we propose a fast and effective method to detect and restore scratches in aerial photos from a photographic archive concerning Sicilian territory. Scratch removal is a typical problem for old movie films but similar defects can be seen in still images. Our solution is based on a semiautomatic detection process and an unsupervised restoration algorithm. Results are comparable with those obtained with commercial restoration tools.
The Urban restoration of the Rabato-Santa Croce district in Agrigento, Sicily: Conservation, resilience and architectural morphogenesis
2015
Il saggio rappresenta un contributo al rilevante tema del restauro urbano, incentrato sulla rivitalizzazione del quartiere Rabato-Santa Croce ad Agrigento, semidistrutto da movimenti franosi nel 1966 e ancora oggi in parziale stato di abbandono. La ricerca inverte i termini del problema così come usualmente posti e non procede attraverso la somma di singole competenze specialistiche, bensì riflette su problematiche sempre diverse in relazione alle complesse implicazioni critico-estetiche e alle cangianti condizioni di conservazione. Al superamento d’una concezione tecnicistica dell’intervento, solitamente espressa dai “manuali del recupero”, segue uno sviluppo metodologico che osserva “caso…
