OBJECTIVE: To evaluate the clinical and patient-reported outcome of all-ceramic zirconia implant supported fixed dental prostheses (FDPs) 5 years after implant installation. MATERIALS AND METHODS: Thirteen patients were treated with two terminally placed one-piece zirconia implants for a three-unit FDP each. The FDPs consisted of a CAD/CAM-fabricated zirconia framework over-pressed with a fluor-apatite veneering ceramic and were adhesively cemented. Survival and success were assessed by applying modified US Public Health Service (USPHS) criteria and preparation of Kaplan-Meier (KM) plots...

Shane J J McCrea
Here we present an analysis of patient perceptions and expectations to dental implant placement and their prosthetic reconstruction, to then consider whether they have an effect on long-term satisfaction levels. A Post-Treatment Completion Questionnaire was designed to analyse whether patient satisfaction is influenced by age and/or gender; has an effect on patient-reported self-confidence levels; contributes to increased levels of oral hygiene; provides further insight into the average pain levels during and after the surgical intervention; or influences further acceptance of dental implant surgery...

The effect of various instruments on titanium dental implant surfaces was evaluated. Furthermore, a clinical guideline was developed regarding the diagnosis, prevention and treatment of peri-implant diseases. Air abrasive devices appear to be the most suitable meachnical instruments to remove biofilm from implant surfaces. From the available chemotherapeutica, (citric)acid and hydrogen peroxide seem to have the best potential. Regular controls and meticulous maintenance from both the patients and dental care professionals are mandatory to avoid problems...

Tissue damage in chronic periodontal disease is driven by the host response to a dysbiotic microbiota, and not by bacteria directly. Among chronic inflammatory diseases of the oral cavity, inflammation and tissue damage around dental implants (peri-implantitis) is emerging as a major clinical challenge, since it is more severe and less responsive to treatment compared to inflammation around natural teeth. We tested whether oral fibroblasts from the periodontal ligament (PDLF), which are present around natural teeth but not around dental implants, actively regulate inflammatory responses to bacterial stimulation...

PURPOSE: The aim of this retrospective study was to evaluate the incidence of inferior alveolar nerve (IAN) lesion and duration of sensitivity disturbances after the insertion of dental implants. METHODS: One thousand sixty-five patients (mean age: 58.9 years) enrolled between February 2004 and July 2015 with partial or full mandibular edentulism were selected to receive dental implants for oral rehabilitation. A total of 3025 implants were placed. After surgical procedures, controls were scheduled at suture removal, that is, 10 days after surgery, and repeated at intervals of 1, 3, and 6 months, and comprised patient interview, clinical examination, and sensitivity tests...

Peri-implantitis has been described as progressive crestal bone loss around a dental implant. The condition is poorly understood, and is challenging to manage; it is commonly and widely attributed to issues with the implant, the implant surface, surgical technique and oral hygiene. The effect of prosthodontic stages of treatment on the postoperatively established state has not been adequately investigated. It is the authors' contention that the manner in which the implant is restored contributes significantly to prognosis and peri-implant disease experience, and that the role of prosthodontic aspects of treatment in the causation of peri-implantitis may be seriously underestimated...

Cerebral palsy is a non-progressive disorder resulting from central nervous system damage caused by multiple factors. Almost all cerebral palsy patients have a movement disorder that makes dental treatment difficult. Oral hygiene management is difficult and the risks for periodontitis, dental caries and loss of multiple teeth are high. Placement of dental implants for multiple missing teeth in cerebral palsy patients needs multiple rounds of general anesthesia, and the prognosis is poor despite the expense...

The use of novel oral anticoagulants (NOACs) has increased in recent times in an effort to overcome the shortcomings of warfarin. They are being used primarily for the prevention of thrombosis caused by atrial fibrillation and offer the advantages of having fewer drug interactions than warfarin, no dietary restrictions, and no requirement for regular blood tests. Although there is reportedly less postoperative bleeding even if the drug is not discontinued during procedures that can cause local bleeding, such as dental procedures, no well-designed clinical studies have assessed postoperative bleeding associated with the use of these drugs...

Rehabilitation of oral function using dental implants is clinically effective and highly predictable. Bone quantity and quality at the implant site both affect the success of the procedure. However, the effect of bisphosphonate (BP) use on mandibular bone quality has not been well documented. The purpose of this retrospective cohort study was to evaluate the bone mineral density (BMD) and cortical thickness of the mandible, as well as the influence of BP use on early implant failure. Twenty-five female patients (≥ 60 years of age) were selected from among 93 candidates with a partially edentulous posterior mandible...

OBJECTIVES: The microplicae is a typical structure of the epithelial cell surface of the oral mucosa. The cell surface is potentially of great significance, as it provides the underlying basis for the protective function of the salivary pellicle. The aim of this study is to investigate whether radiation therapy affects the surface morphology of the superficial cells of the human oral mucosa in patients who have received radiotherapy for oral cancer. MATERIAL AND METHODS: Oral mucosal tissue samples from 91 patients were collected during dental implant surgery or ablative surgery...

Our ability of screening broad communities for clinically asymptomatic diseases critically drives population health. Sensory chewing gums are presented targeting the tongue as 24/7 detector allowing diagnosis by "anyone, anywhere, anytime". The chewing gum contains peptide sensors consisting of a protease cleavable linker in between a bitter substance and a microparticle. Matrix metalloproteinases in the oral cavity, as upregulated in peri-implant disease, specifically target the protease cleavable linker while chewing the gum, thereby generating bitterness for detection by the tongue...
