The association of systemic condition and medications on alveolar bone loss and tooth attrition.

Objective: Periodontal disease is caused by subgingival bacteria that adversely affect the host immune system and create and maintain unmitigated inflammation in gingival and periodontal tissues. The condition is also linked to systemic conditions including cardiovascular disease, diabetes, and arthritis. Periodontitis elevates the bacterial load and spreads systemic inflammation through infection and inflammation.

A novel digital way to measure the vertical and horizontal dimensions of the supra-crestal peri-implant soft tissues.

Aim: To report on a novel digital superimposition workflow that enables measuring the supra-crestal peri-implant soft tissue dimensions all along implant treatment and afterwards.

Materials And Methods: A preoperative CBCT and intra-oral scans (IOS) are successively taken before surgery, at the end of the healing period, at prosthesis delivery, and over time; they are digitally superposed on a dedicated software. Then, the stereolithography files (STL) of the healing abutment, of the prosthetic abutment and the crown are successively merged into the superposition set of IOSs.

Simultaneous implant placement and restoration with guided bone regeneration in the mandibular anterior region.

Background: Restoring the mandibular anterior teeth by implants can be difficult due to potential complications arising from using prosthetic implant connections that are larger than the incisors at the cementoenamel junction level.

Methods: This retrospective study is aimed at determining the survival and esthetic outcomes of anterior mandible implants immediately placed and restored in patients diagnosed with stages 3-4 periodontitis. The study included 75 implants that were inserted along with guided bone regeneration in 42 patients.

Osseoconduction of an Airborne Particle-Abraded and Etched Titanium Alloy Surface in Type IV Bone: A Human Histologic and Micro-CT Evaluation.

The present study aimed to evaluate the osseoconduction ability of an airborne particle-abraded and etched (SAE) titanium alloy surface when placed in humans with poor bone quality. Four patients scheduled to receive an implant-supported full-arch prosthesis received two additional reduced-diameter implants to be harvested after 6 months of submerged healing. Undecalcified vestibulopalatal/vestibulolingual histologic sections were prepared after the micro-computerized tomography (μCT) examination.

STT at implant sites was divided into two groups: thin (n = 21, mean STT = 2.

In vitro Interactions between and K12 on a Titanium Cylindrical Surface.

Peri-implantitis is a steadily rising disease and is caused by oral bacterial pathogens able to form biofilm on implant surfaces and peri-implant tissues, making antibiotics treatment less effective. The use of commercial probiotics against oral pathogens could serve as an alternative to prevent biofilm formation. is one of the early colonizers of biofilm formation in dental implants.

Characterization of a Macro- and Micro-Textured Titanium Grade 5 Alloy Surface Obtained by Etching Only without Sandblasting.

Our purpose was to physically characterize the surface, and the subsurface, of a macro- and micro-textured titanium grade 5 dental implant surface obtained by etching only, without sandblasting. The topography, surface roughness, as well as the surface structure and subsurface distribution of elements, were determined by scanning electronic microscopy (SEM), non-contact profilometry, X-ray diffraction (XRD), and a concentration profile performed by Auger electron spectroscopy (AES). The hydrogen concentration in the implants was measured; the ability to generate nanostructures when stored in deionized water was also investigated.

In another patient, 3 implants were inserted in the mandible to rehabilitate a failing bridge.

[New protocol combining orthodontics and implant therapy for partially edentulous adult patients. Part I: Description of the Decker protocol].

Introduction: The treatment of adult malocclusion is usually complex and pluridisciplinary. Its prognosis is not reliable. We present a new clinical protocol to improve the management and final result.

Unconventional Implant Placement Part III: Implant Placement Encroaching upon Residual Roots - A Report of Six Cases.

Background: When a residual root is found in the way of a planned implant placement, invasive surgery is usually performed in order to remove it. Consequently, implant therapy is rendered more complex and lengthy.

Purpose: We present 6 cases treated according to an unconventional protocol in which invasive surgery was avoided by allowing the implants to encroach upon the residual roots in order to permit a prosthetically driven surgery.

[Implants in contact with tissues other than bone. Is there room for a potential paradigm shift?].

Rationale: Modern dental implantology is now 30 year old. During this period of time, concepts have evolved and triggered several paradigm shifts. The aim of the present paper is to present a case treated with an innovative unconventional protocol.

Immediate implants placed in infected and noninfected sites after atraumatic tooth extraction and placement with ultrasonic bone surgery.

Background: Only a few reports deal with implants placed in infected postextraction sites.

Purpose: Survival rates of a cohort of immediate implants cases placed in acute and chronically infected sites were compared with a cohort of noninfected ones while (1) tooth extraction and osteotomy sites were prepared with a piezosurgery device and (2) ultrasonication was applied to abate the bacterial charge at infected sites.

Materials And Methods: Eighty-six patients received 168 immediate implants distributed into three groups: noninfected (85), acute (36), and chronically (47) infected sites.

Microbial biofilm modulation by ultrasound: current concepts and controversies.

Biofilm elimination is often necessary during antimicrobial therapy or industrial medical manufacturing decontamination. In this context, ultrasound treatment has been frequently described in the literature for its antibiofilm effectiveness, but at the same time, various authors have described ultrasound as a formidable enhancer of bacterial viability. This discrepancy has found no solution in the current literature for around 9 years; some works have shown that every time bacteria are exposed to an ultrasonic field, both destruction and stimulation phenomena co-exist.

[Computer-assisted implantology].

We had for aim to present the three applications of computer-assisted implantology: preoperative exploration of the surgery site, guided surgery, and preparation of the temporization prosthesis before surgery. Cases are presented for each indication and their clinical relevance is discussed.

[Unconventional transradicular implant placement to avoid invasive surgeries: toward a potential paradigm shift].

The authors had for aim to present a new minimally-invasive protocol to rehabilitate anterior maxillary edentulism due to an impacted tooth. The implant is placed without removing the impacted tooth, which intercepts the implant trajectory. The inclusion/exclusion criteria have not been defined yet but this protocol goes against the consensual concept that no implant surface other than implant-bone interface should be tolerated.

Early bone formation around immediately loaded FBR-coated implants after 8, 10 and 12 weeks: a human histologic evaluation of three retrieved implants.

The surface characteristics of dental implants play an important role in the osseointegration process. Over the years implant surfaces have been subjected to different treatments, including turning, plasma spraying, coating, sand blasting, acid etching, and anodization. FBR coating is a fully resorbable calcium phosphate (CaP) coating made of brushite, obtained by electrochemical deposition on titanium plasma-sprayed (TPS) implants; this bioactive layer may be totally resorbable in 6-12 weeks and once the FBR coating has been resorbed, the newly formed bone is in contact with the roughness of the TPS surface.
