Book excerpt: BACKGROUND: Resonance frequency analysis (RFA) is a simple, practical, reproducible, clinically feasible and non-invasive method that allows to safely assess the degree of stiffness that the implant is within the bone structure. AIM: According to the applied methodology, the aim of this clinical study was to perform a research to evaluate the stability of two different types of implants, with resonance frequency analysis (RFA). METHODS AND MATERIALS: This clinical research was approved by the ethical committee (Plataforma Brasil) under the number CAEE 54726816.6.0000.5374. Patients were submitted to conventional dental implant surgery with installation of two implants, Straumannu2019s, Bone Level Tapered (BLT) 4x8mm and SINu2019s Unitite 4x8,5mm. Each patient received two implants, one from each brand, with their respective healing abutments. The stability of the implants (ISQ) was measured by the Osstell apparatus. A torque of 10Ncm was applied to the smartpegs. The stability of the implants was measured at the time of surgery, four, six and eight weeks post-surgery. At each stage, three measurements were taken and a mean (mean ISQ) was obtained for each implant. RESULTS: Each group (SINu00ae and Straumannu00ae) was treated, separately, with ANOVA and the differences found identified by Tukey-Kramer multiple comparisons test. The Straumann implants show no statically difference in the ISQ values for all measurements. The SIN group showed only a statistically lower ISQ value in the 4 week. The two groups were compared in all stages with a paired t-test. The ISQ values u200bu200bfor the Straumann groups were statistically higher in all stages (P

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.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Clinical studies have shown that posterior maxilla is associated with challenges in the implant dentistry. Sinus lift procedures are required for sufficient bone volume in the maxillary ridge. Osseointegration of titanium implants in and their stability in grafted and nongrafted sites has been shown by means of resonance frequency analysis (RFA). Aim/Hypothesis. The aim of our study was to evaluate the implant stability quotient (ISQ) results of the resonance frequency (RF) in grafted and nongrafted sinus lift procedures on the first day of surgery and after 1, 4, 16 weeks of healing period. Materials and Methods. In this study were included 58 healthy patients, where sinus lift was obtained. In all, 137 SLA ITI Standard plus implants were placed. In the first group of 27 patients, 62 implants were placed following sinus lift and grafted with Bio Oss 0.25u20131 mm particle size (small particles), and in the second group of 31 patients 75 implants were placed without bone augmentation. Resonance frequency analysis (RFA) was measured at both groups to get implant stability quotient (ISQ) values. Student's t test was used to calculate P values for ISQ with Statistica 7. Results. On the first day and one week after surgery no statistical difference was observed in ISQ values of implants placed in grafted and nongrafted sinus lift procedures (p=0,651). After 4 and 16 weeks, grafted sites showed higher ISQ values than the control site. Conclusion. Sinus lift procedures on grafted sites offer better long term stability. RFA values during the healing period are predictable for the implant outcome during maxillary sinus lift procedures.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Dental implants have become a predictable treatment modality that is widely used in the rehabilitation of edentulous areas. The primary stability achieved shortly after implant installation is necessary for the success of osseointegration, as well as one of the main factors that influence the survival rates of the implants. This study aimed to compare the primary and secondary stability, measured by Resonance Frequency Analysis (RFA), in implants of different lengths installed in areas submitted to maxillary sinus lift using BioOssu00ae as graft biomaterial. Correlation between RFA and implant insertion torque was also assessed.The study was approved by the Research Ethics Committee 53955215.0.0000.5137.Twenty implants of 9 and 11mm were inserted into areas submitted to maxillary sinus lift. The insertion torque was measured using the Bien Airu00ae motor and the Osstellu00ae, determined the ISQ (Implant Stability Quotient) at two times: the day of implant installation (T1) and 90 days after implant installation (T2). A D'Agostino-Pearson normality test showed that the data of these variables, Implant Stability Quotient (ISQ) and insertion torque, have a normal distribution. The paired t-test was performed to assess the existence of differences in ISQ between T1 and T2. A Student's t-test was performed to assess any differences in ISQ between the 9mm implants and the 11mm implants. The Pearson correlation test was used to evaluate the existence of a correlation between ISQ and insertion torque at T1.No differences were observed in the ISQ between T1 and T2 when the 20 implants were grouped, nor when the 9mm implants were evaluated separately. In contrast, when the 11mm values were evaluated separately, the ISQ was significantly higher at T2 than at T1 (p 0.05). At T1, the 9mm implants had a higher ISQ than the 11mm ones (p 0.05), whereas at T2 the 11mm implants showed a higher ISQ than the 9mm implants (p

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: BACKGROUNDSinus lift procedures are considered a safe and predictable option for bone gain in the posterior maxilla. Several studies demonstrated that anorganic bovine bone is considered a predictable option for grafting the maxillary sinus and provide high implants survival rates. Modern surfaces chemically modified sandblasted and acid-etched with hydrophilic properties aims to decrease healing time and afford early loading of dental implants. However grafted sites may represent a challenge for early loading of implants compare to native bone.AIMThe aim of this study was to evaluate the implant stability measurements using resonance frequency analysis (RFA) of a new surface implants placed in native bone and augmented sites at baseline and after 8 weeks.MATERIAL AND METHODSSeventeen edentulous patients with deficient bone high in the posterior maxilla (5mm) were select according to tomographic analysis for bilateral sinus floor elevation. All procedures were performed with the lateral window approach using 100% anorganic bovine bone and collagen membrane over the window. After 8 months, a second tomographic exam was used for planning the placement of 6-8 dental implants with a sandblasting and acid etching surface maintained in an isotonic solution of 0.9% sodium chloride. The implants were maintained submerged in all patients. After 8 weeks, the re-opening surgeries were performed and provisional prosthetic rehabilitation was started. All implants were rehabilitated with splinted crowns. The insertion torque was measured at the day of the implants placement (baseline) while the resonance frequency analysis (RFA) was performed at baseline and after 60 days. The implants survival was evaluated after 6 months of provisional prosthetic rehabilitation.RESULTS A total of 113 implants were performed in augmented sites and native bone (89 and 24, respectively) to allow fixed prostheses oral rehabilitation. Four implants failed and a survival rate of 96,46% was achieved after 6 months of provisional prosthetic rehabilitation. It was showed that the implants placed in the native bone (~60Ncm) presented higher values of insertion torque than the implants placed in grafted areas (~45Ncm). Regarding the RFA analysis, implants placed in grafted areas presented greater stability in relation to the implants placed in native bone in the period of 60 days. In addition, the RFA of the implants placed in native bone reduced at the period of 60 days in relation to the baseline period. All the implants presented an adequate value for the induction of occlusal loading ( 60).CONCLUSION AND CLINICAL IMPLICATIONSWithin the limitations of the present study, RFA analysis demonstrated that the new implant surface presented adequate values for occlusal loading after 60 days of implant insertion in augmented sites. Considering the short term period evaluation (6 months) a good implant survival rate of 96,46% can be achieved for early loading in augmented sites.
