Isolated lip dermatitis (atopic cheilitis), successfully treated with topical tacrolimus 0.03%

2020

Background Exfoliative and erosive cheilitis, may be a source of speech and chewing discomfort, but may also be an aesthetic issue for the patients affected. Such a clinical presentation may implicate a variety of inflammatory conditions, including atopic (eczematous) cheilitis. Topical and systemic agents, e.g. corticosteroids, have been used to treat inflammatory lip conditions. Topical tacrolimus has also been used in some inflammatory lip conditions. Material and Methods We performed a retrospective clinical analysis of atopic cheilitis patients. Results Between 2015 and 2020, we addressed 7 (seven) patients with atopic dermatitis affecting only lips and were diagnosed as atopic-eczemat…

Controversies in ameloblastoma management: Evaluation of decision making, based on a retrospective analysis

2020

Background The ameloblastoma management is still challenging to the high recurrence rates and significant morbidity associated with radical treatment. The purpose of this 10-year retrospective study was to analyze the influence of ameloblastoma type and treatment strategy on the long-term outcomes and recurrence rates. Material and Methods The retrospective analyses of 64 histologically-confirmed ameloblastoma cases was performed. The possible risk factors for recurrence and the development of complications were estimated statistically. Results The treatment strategy applied for this group of patients was the following: thirty-four patients (53.1%) were treated conservatively with enucleati…

Design characteristics, primary stability and risk of fracture of orthodontic mini-implants: Pilot scan electron microscope and mechanical studies

2013

Objectives: Orthodontic mini-implants (OMIs) are increasingly used in orthodontics but can fail for various reasons. This study investigates the effects of OMI design characteristics on the mechanical properties in artificial bone. Material and Methods: Twelve self-drilling OMIs (2 small, 6 medium, 4 large) from 8 manufacturers were tested for their primary stability in simulated medium-high cancellous bone and the risk to fracture in high-density methacrylate blocks. For the assessments of the maximum insertion torque (IT) and torsional fracture (TF) 5 of each OMI were used and for the pull-out strength (POS) 10. The OMIs were inserted with a torque screwdriver (12 sec/360°) until the bott…

The effects of surgical preparation techniques and implant macro-geometry on primary stability : an in vitro study

2016

Background The attainment of a good primary stability is a necessary condition to ensure the success of osseointegration in implantology. In type IV cancellous bone, however, it is possible that a reduced primary stability can lead to an increased rate of failure. The aim of this study was therefore to determine, with the help of the resonance frequency (Osstell mentor), which technique of implant site preparation (piezo surgery, conventional, under-preparation, bone compaction, osteodistraction) and macro-geometry is able to improve implant stability in type IV cancellous bone. Material and Methods 10 pig ribs were prepared with a surgical pre-drilled guide, calibrated for a correct implan…

In vitro evaluation of the influence of bone cortical thickness on the primary stability of conventional- and short-sized implants

2022

Made available in DSpace on 2022-04-28T19:50:57Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-01 Background: The aim of this in vitro study was to evaluate the influence of the cortical thickness on the primary stability of short and conventional-sized implants with two types of prosthetic connection. Material and Methods: Seventy-two implants were used. These implants were placed in polyurethane blocks that simulated low-density bone tissue (type IV bone), with two bone cortical heights (type I bone): 1mm and 3mm. The implants were divided into 6 groups with 12 implants each according to the type of prosthetic connections (external-hexagon -EH and morse taper- MT) and implant s…
