Book Description
Obtaining and maintaining implant stability are prerequisites for the clinical success of implant prostheses. Since primary stability is a direct consequence of bone-implant contact, it depends on bone density, surgical technique, and macroscopic and microscopic morphology of the implant used. Primary stability can be either measured by insertion torque or ressonance frequency analysis, but no relation between these two is clearly described. The objective of this study was to evaluate the statistical correlation of primary stability through ressonance frequency analisys (RFA) and manual torque of insertion through literature review and case series study.This study was conducted on a post-graduate clinic (CLIVO- Rio de Janeiro,Brazil), where fourteen dental implants had their manual torque and RFA measured using a manual torque device during instalation. RFA measured the Implant stability Quoeffcient(ISQ) using a smartpeg after instalation in 5 different positions ( bucal, lingual, occlusal,mesial and distal).All of the fourteen implants had the same conical connection and were placed in the mandible or maxila. The mean ISQ measurements and manual torque were submitted to statistical analysis to determine a possible correlation.We evaluated 13 implants, 9 implants performed in female patients and 4 male patients, 5 in maxilla and 8 in mandible. For the study, internal connical connection dental implants were used. In order to verify the correlation between TORQUE and ISQ, the statistical software.

Book Description
Background:Successful osseointegration of dental implants is determined by several factors including implant surface characteristics, bone morphology and metabolism as well as primary stability of dental implants. Lack of primary implant stability and other co-factors may result in loss of osseointegration, leading to implant failures. Precise presurgical site analysis, stringent case selection, comprehensive planning and accurate surgical approach are prerequisites for functional and esthetic success. Aim:The aim of the present in vitro study was to compare insertion and removal torque of implants in polyurethane foam devices simulating bone qualities 1 and 2. Material and Methods;Sixty-four dental implants (NobelReplace Conical Connection, Nobel Biocare Gu00f6teborg, Sweden) were inserted (calibrated Elcomed, W&H, Austria) by 2 different surgeons (ML & SV) in solid rigid polyurethane foam devices with density of pcf (pounds per cubic foot) 30 or 40, which were laminated with pcf 50, for simulating bone qualities D1 and D2, respectively, according to Misch Parameters evaluated were insertion and removal torque, differences between 2 diameters (3.5 mm/13 NP and 4.3 mm/13 RP) and differences between the bone qualities. Pearson correlation coefficient was evaluated for determining the correlation between insertion and removal torque in all groupsResults: Insertion torque reached a maximum of 800 Nmm in foam simulating bone quality D1 with diameter 3.5 and 4.3 mm implants (min: 140/638; mean 512.1/763.1; SD:192/50.1), and a maximum of 568 Nmm for bone quality D2 with 3.5 mm diameter implants (min: 221; mean: 466.8; SD: 78.6). RP Implants reached a maximum insertion torque of 800 Nmm in bone quality D2 (min:339; mean: 471.8, SD: 144.7).Removal torque amounted to a maximum of 800 Nmm in bone quality D1 (min:89; mean: 365.8; SD: 194.6) for 3.5 mm diameter implants and a maximum of 694 Nmm for 4.3 mm implants (min: 409; mean: 551.1; SD: 70.3). In quality D2 bone , the 3.5 mm implants reached 379 Nmm as a maximum (min:169; mean: 317.1; SD: 49.4), whereas 4.3 mm implants had a maximum removal torque of 637 Nmm (min: 238; mean:362.5; SD:96.2).The correlation of insertion and removal torque were significant (r = 0,747 to r=0,895 for the different groups).Conclusion and clinical implication:Evaluation of insertion torque is appropriate method to assess primary stability of dental implants. Further clinical studies are needed to verify a correlation between preoperative assessment of bone quality and insertion torque to implement appropriate loading protocols.

Book Description
Background: Primary implant stability contributes to the success of dental implant placement and affects long-term function. Factors that contribute to the primary stability and osseointegration of a dental implant include the quality and quantity of bone present at the site of placement as well as the shape and surface treatment of the implants. There are numerous methods that assist the clinician in determining implant stability during placement and to confirm osseointegration after a period of healing. Their reliability to predict implant success, however, has not been proven. Torque measurements acquired during implant placement have been used as a method for assuming implant stability, as they provide valuable information about the local bone quality at the site of placement. The operator's tactile assessment of implant stability during placement is often used as the main indicator of primary implant stability, but limited data is available to validate the accuracy of this assessment. Methods: 100 implants placed in the periodontology clinic were analyzed for implant torque during placement. Assessment of the implant stability was first estimated by the clinician in Ncm and in bone density using the Leckholm and Zarb definition and was compared to the implant stability measured using a calibrated torque-measuring device. Other variables, such as years of surgical clinical training, implant system, and location of implant placement were also recorded. Results: There was no significant difference (P = 0.3348) between the estimated implant insertion torque when compared to the calibrated torque values. A significant difference in the ability to measure insertion torque was noted when implants were being placed in socket-converted sites (P = 0.0076), in the mandible (P = 0.0270), and when placing regular platform (P = 0.0433) or wide platform (P = 0.0156) implants. Conclusion: The trained clinician has the ability to accurately measure insertion torque of a dental implant during placement. Within study limitations, it may be concluded that the ability of a clinician to perform this task was effected by placement of a dental implant into a previously socket converted site, the placement of a dental implant into the mandible, and when using wider diameter implants.

Book Description
Background :The question of predictable achievable primary stability of dental implants in the edentulous lower jaw and subsequent possibilities of immediate loading and shortened treatment time for patients is the aim of the present invivo study. Aim:The aim of the present study was to evaluate a possible correlation between voxel values and insertion torque of dental implants in the interforaminal region.Material and Methods;A total of 20 patients with edentulous lower jaws participated in this pilot study. All patients underwent CBCT scan prior to surgery and the obtained data was used for 3-dimensional planning (Simplantu00ae, Dentsply Sirona, Germany) also to determine voxel values. The same implant system (Nobel Replace CCu00ae;Nobel Biocare, Switzerland, Zurich) was used throughout, and all implants were inserted as dictated by the manufactureru2019s drilling protocol. All patients received 4 interforaminal implants. Primary stability was recorded in terms of insertion torque, which was recorded in Nmm by a calibrated device (Elcomed, W&H, Germany). Results: A total of 20 patients (10 women, 10 men) at a mean age of 65.7 years (min: 41 max: 81 years) participated at this pilot study. Insertion torque amounted from min.: 56.0 Nmm to max: 800.0Nmmt(mean: 463.4 SD:167.5). Grey density voxel values evaluated were min.: 425.2 and max.:1479.1 (mean:944 SD227.6). The Pearson correlation coefficient was significant for the correlation between insertion torque and voxel values (r = 0.624; p = 0.003). Linear regression model showed significant influence of bone quality (p=0.587), diameter (p=0.012) and voxel value (p=0.042) on insertion torque. Conclusion and clinical implication:Preoperative evaluation of grey density voxel values can be an appropriate method to assess primary stability of dental implants. Further clinical studies are needed to verify the results of this clinical pilot study.

Book Description
Dental implant treatments are widely used and can be an option for lost teeth. Most treatment alternatives are limited due to bone structure, bone density, and patient’s health condition. This book is focused on simple and complicated clinical cases, different types and designs of implants, and also the way to obtain bone-to-implant contact. We have also sought to assess different biomaterials, bone stimulators, and types of dental implants that can reduce the gap, protect the peri-implant bone, and increase the aesthetics. The relationship of bone formation and biomaterials with dental implants is the key factor in bringing back the full reconstruction of soft and hard tissues. Additionally, the type of materials used for implant development are extremely important, especially in relation to strength and bending forces. The contact and protection of bundle bone with both biomaterials and implants will provide highly predictable success in aesthetics and function.

Book Description
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

Book Description
Background: Implant stability has been recognized as an essential factor link to osseointegration and predicts the survival rate of dental implants. The resonance frequency analysis (RFA) is a noninvasive device providing results in the form of the implant stability quotient (ISQ). The primary stability is also influenced by numerous factors such as surgical technique, implant morphology as well as bone quality and quantity. In the posterior maxilla, the sparse bone density leads to low primary stability. Aim: This retrospective study aims to analyze the factors that influenced the primary stability of dental implant of posterior maxilla.Material and methods: Patients records of treatment performed between January 2014 to December 2018 were reviewed for primary implant stability. Patients who had Straumannu00ae implants at posterior maxilla and exhibited RFA both buccal and mesial area immediate implant placement were included. The following variables were determined; patient age, gender, implantation region, timing of implant placement after tooth extraction (immediate placement, u2264 4 months after extraction, > 4 months after extraction), implant geometry (diameter and length), and adjunctive procedures during implantation (guided bone regeneration and transcrestal osteotomy). The RFA value was used The Kolmogorov-Smirnov Test to determine normal distribution. The Chi-Square Test was applied to compare the relationship between qualitative variables and the Kruskalu2013Wallis test was used to compare the mean. The Pearson correlation coefficient was used to determine correlation.Results: Seventy implants in 53 patients (male 19, female 34) were found. The mean age of this sample size is 59.04uf0b11.41 years old. The mean value of RFA of the buccal area is 65.76uf0b11.44 and the mean of RFA of mesial area 66.59uf0b11.55. The RFA value of the buccal and mesial area was significant correlate (p
