Available in PDF, EPUB and Kindle. Book excerpt: The use of dental implants in the rehabilitation of partially and completely edentulous patients has been significantly increased in recent years. Although high survival rates of implants supporting prosthesis have been reported, failure still happens due to bone loss as results of primary and secondary implant stability. Primary stability of an implant mostly comes from mechanical interaction with cortical bone while secondary stability happens through bone regeneration and remodelling at the implant/bone interface. Defining the implant stability remains a challenge in dentistry and several researches have been made in this field. To detect implant stability, various diagnosis analyses have been employed. Among them, resonance frequency analysis (RFA) is an objective method of monitoring implant/tissue integration. In this thesis, experimental and numerical studies are carried out to find the effect of some parameters affecting the stability of dental implant by using RFA. Modal analysis technique is employed to investigate the effect of coupled mode shapes in dental implant. Moreover, the primary stability of dental implant that indicates the process of bone-implant integration is investigated. Resonance frequency of jaw-implant structure is carried out using finite element modelling. Different implant-bone interface conditions are studied for this investigation. The effects of endosseous implant angulation on the resonance frequency of implant are studied. MIMICS, a three dimensional (3D) modelling software was used to construct a 3D model of a pig mandible from computed tomography (CT) images. The resonance frequency of the implant was analyzed using finite element (FE) modal analysis in a simulated environment. The MIMICS is also used to investigate effect of soft tissue surrounding the implant on the RF of implant. In addition, three different pig mandibles were employed to assess the effect of some parameters affecting resonance frequency of implant. Finally, experimental studies are carried out to investigate the effect of soft tissue on RF of implant. A novel device is also designed for stability analysis of dental implants.

Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 1990 in the subject Medicine - Dentistry, grade: A 3.444 GPA, University of Louisville (University of Louisville Graduate School), course: Master of Science Oral Biology, language: English, abstract: When planning osseointegrated implant therapy, radiological mapping of the prosthesis site is important to detail bone dimensions and quality, and to locate anatomic structures. Diagnostic imaging techniques for treatment planning in endosseous implant therapy were analyzed for dimensional accuracy. Modified mandibular symphysis was the most accurate occlusal survey (mean percent of error = 24.73), followed by the mandibular symphysis (mean percent error = 30.43) and the cross-sectional technique (mean percent error = 41.27). The interforaminal width (mental foramen) of the pantomograph can be accurately corrected using pre-exposure intraoral diagnostic wire and the formula: Distortion factor = Radiographic length of wire / Actual length of wire Linear tomography (Quint Sectograph) was used to diagnose the cross-sectional anatomy of the maxilla and mandible. The circumferential morphology of the tomograph correlated well with the dissected anatomy. Magnification percentage (13.11 height) was slightly higher than the manufacturer's recommendations. The loss of teeth and their subsequent replacement has been a perplexing problem in dentistry. Many patients think the loss of teeth is a consequence of aging. In fact, some patients wish to have their teeth removed and replaced with "good dentures." However, dentures are not a replacement for teeth but rather a substitute for no teeth. Dentists have long realized the benefits of retaining teeth for anchorage of removable or fixed partial dentures and will go to great lengths to save these potential abutments. Therefore, it would naturally follow that in the absence of natural anchorage one would look for an anchor¬age substitute, hence, the evolution of dental implantology.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Osseointegration is defined as: a direct structural and functional connection between ordered, living bone and the surface of a load-carrying implant, without intervening soft tissue, is critical for implant stability and considered a prerequisite for long-term clinical success of endosseous dental implants. Many types of implant surface modification are available nowadays to enhance osseointegration. Light-activated TiO2 surface is one of the surface treatment of titanium. The purpose of the present study was to investigate the effects of the implants, which were coated with the light responsive photocatalytic material, on osseointegration. Maxillary first molars of 6 male C57BL/6NCrSlc mice were extracted bilaterally. Eight weeks after the extraction, two implants were placed in both sides of the maxilla. Photocatalyst implant was placed on the right side (test group) and conventional pure titanium implant was on the left side (control group). After 3, 4 and 6 weeks of implant placement, the animals were sacrificed. The implants and the surrounding tissues were analyzed radiographically. All implants were osseointegrated into bone. But there were no statistically significant differences.

Book excerpt: "Abstract Dental implant supported overdentures have been known to improve patient satisfaction and quality of life. Mini Dental Implants (MDIs) have several advantages over conventional implants. The major advantages are that 1. The surgery is minimally invasive, 2. Transmucosal placement is possible using a single pilot drill and 3. They can be loaded immediately. These also offer an alternative for patients with conditions that restrict them from being candidates for standard width dental implants. Despite these advantages, evidence of their potential for osseointegration and long-term success is lacking, and there are relatively few studies investigating the osseointegration of MDIs. We hypothesized that there is no difference in the osseointegration potential of MDIs and standard-sized implants. To test this hypothesis, an in vitro and a randomized in vivo animal study were designed. From the in vitro investigation, we found that implant surface property may play a significant role in the ability of osteoblastic cells to form initial attachment and proliferation. Thus, we designed three in vivo experiments using a rabbit tibia model to compare MDIs and standard implants for their potential to osseointegrate at different time-points. We used three different methodologic approaches: In the first, a resonance frequency analysis was carried out; results indicated that there is no difference in stability between the MDI and comparator implants (p0.05; Wilcoxon's matched pair's sign-rank test). In the second approach, a histologic study showed that there were no differences between the implant types in the amount of bone implant contact (p0.05; Mann-Whitney). Finally, nanoindentation testing demonstrated that the mechanical properties of bone near and apart from the bone/implant interface were similar between the two implant types (p > 0.05; ANOVA). In summary, the evidence from this project suggests that MDIs offer similar osseointegration potential as commonly-used standard sized implants. Therefore, we recommend that randomized clinical trials with long-term follow-ups be conducted to determine whether MDIs and standard sized implants will demonstrate similar osseointegration characteristics under function and in patient populations." --

This book was released on 2012 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Implant stability is an important factor guiding the selection of placement and loading protocols. An evaluation of the currently available techniques for measuring stability clearly demonstrates a need for a non-invasive, quantitative, repeatable, and reliable way to measure implant stability over time. A potential candidate for this purpose is resonance frequency analysis (RFA). A retrospective study was performed on implant patient data collected over a five-year period. Patients were categorized according to their placement protocol (one-stage vs. two-stage) and loading protocol (early vs. traditional). RFA measurements were recorded during placement and prior to loading. Survival or failure was determined after a minimum follow-up period of two years. Receiver operating characteristic (ROC) statistical analysis was used to determine ISQ cut-off points with respective sensitivity and specificity values for different placement and loading protocols. In predicting implant failure, sensitivity progressively increased and specificity decreased as ISQ cut-off values increased. All failures occurred at ISQ

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Following the placement of an oral implant, primary mechanical stability is gradually replaced by biological stability. Primary stability is the mechanical engagement of an implant with the surrounding bone, whereas bone regeneration and remodeling phenomena create the secondary (biological) stability of the implant. It is of clinical relevance to know the development of implant osseointegration after installation, as well as to detect the incidence of screw loosening after the implantu2019s superstructure is mounted.Objectives: The aim of this study was to examine the progress of implant osseointegration and screw loosening by means of a resonance frequency analysis (RFA) in the rabbit tibia.Methods: One mature New Zealand White rabbit was used. Six titanium implants were installed in the rabbit tibiae bilaterally. A small 3D-accelerometer was mounted rigidly onto the implant abutment, and impulsive vibration was directly applied to the abutment to vibrate the implant in perpendicular to direction of the tibia and implant (x-axis). Two RFA values of x- and y-axis directions (RFx and RFy) were used for evaluation. The y-axis was defined in parallel to the tibia. Also implant stability was measured by implant stability quotient (ISQ) value with Osstellu00ae. These values were measured immediately after implant placement, twice a week for the first month and once a week for the second month. After 8 weeks, RF values and Peiotestu00ae (PT) values were recorded with 13 different screw conditions, i.e. abutment screw tightened with 10N torque (starting point) and the screw was loosened by 5 degrees from 0 to 90 degrees, and the animal was sacrificed.Results: In most implants, ISQ values tend to decrease until 7 to 10 days after installation and then gradually increased. ISQ values at day 7 and 10 were significantly lower than at other time points, except for two implants which located in the distal side of tibiae. In the RF, no consistent tendency with time was observed among six implants in both directions. According to degree of the screw loosening, the RF and PT values significantly changed (p
