This study aims to evaluate the awareness, knowledge, and approval of dental implant treatments among dental patients in our hospital. Materials and Methods: This was a cross-sectional study conducted among 442 adult patients attending the Dental Clinic of Usmanu Danfodiyo University Teaching Hospital Sokoto State, Nigeria, from March 2021 to February 2022. After obtaining ethical approval, participants were recruited using a structured questionnaire. This questionnaire consist of 12 questions, assessing the patient's awareness, knowledge, and willingness to approve a dental implant as an option for teeth replacement. The collected data were analyzed using SPSS (IBM SPSS) software version 20. Results: There were 293 (66.3%) males and 149 (33.7%) females with an mean ± standard deviation of age 37.4 ± 12.4 years and a range of 20–65 years. Two hundred and forty-six (55.7%) were unaware of a dental implant as an option for missing teeth replacement and 196 (44.3%) have heard of a dental implant. The majority of respondents (73%) heard about dental implants from a dentist, followed by social media (19.4%). Responses from questions yielded variable responses about the knowledge of implant. Regarding the patient's approval, 80.1% expressed their willingness to replace missing tooth/teeth with a dental implant. Conclusion: This research revealed a below-average level of awareness of dental patients about a dental implant as an option for teeth replacement. Dental surgeons need to do more on information dissemination about the use of dental implants.","PeriodicalId":212982,"journal":{"name":"Journal of Dental Implants","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133441238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Swamy","doi":"10.4103/jdi.jdi_10_22","DOIUrl":"https://doi.org/10.4103/jdi.jdi_10_22","url":null,"abstract":"Purpose of Study: Bacterial biofilm-induced peri-implantitis has been one of the leading causes of implant failure. There are a plethora of local and systemic factors that have been studied at a depth and thereafter have been proven to have a contributory role in the overall disease progression. Epidemiological factors such as site specificity and gender stand to be two confounding factors that have insufficiency in the literature regarding their involvement in the same. Thus, the present article aims to address this gap in the literature and present conclusive evidence about the gender-based comparative evaluation of the microbial load of Aggregatibacter actinomycetemcomitans, one of the potential periodontopathogens for the disease progression, present in anterior versus posterior implant sites. Materials and Methods: Twelve patients (six males and six females) undergoing the implant prosthetic rehabilitation at two intraoral sites, one anterior and one posterior region, were selected as suitable subjects and the healing abutments as the clinical test samples. Culture-independent microbiological analysis was carried out for all the samples for quantification of A. actinomycetemcomitans. Results: The mean viable bacterial DNA count was 503076.49 copies/μL for the male subjects and 474587.85 copies/μL for the female subjects. Hence, there was no significant function correlating gender specificity and the viable bacterial DNA counts. The mean total of viable bacterial DNA counts for the anterior region (site 1) was 407087.17 copies/μL and for the posterior region (site 2) was 570577.17 copies/μL, irrespective of the gender. Thus, a highly significant difference was observed in the mean viable bacterial DNA counts between site 1 and site 2 (F = 20.214; P = 0.001) irrespective of the gender. Conclusion: There seems to be no gender-based predilection for the quantification of viable bacterial DNA counts for A. actinomycetemcomitans. However, a propensity for the presence of higher bacterial load of A. actinomycetemcomitans, one of the causative microorganisms of per-implant diseases, does exist for the implants placed in the posterior region as compared to those placed in the anterior region.","PeriodicalId":212982,"journal":{"name":"Journal of Dental Implants","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132813950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the implant, analog is a lab component, it can be reused multiple times. Reuse of implant analogs may be desirable for both environmental and financial aspects. When implant analogs are reused, it is important to be assured that they are as accurate as new ones. Reusing of implant analog results in loss of precision which is the major key factor in the failure of implant prosthesis. Purpose of the Study: The purpose of the present in vitro study is to assess the effect of multiple reuse of implant analogs of three different materials (SS, Ti, Al) on the dimensional accuracy (external and internal diameter) of implant analogs and the marginal gap between analog and abutment by using two die materials at different time intervals (0, 3rd, 6th, 9th, and 12th). Materials and Methods: Three commonly used implant analog materials (stainless steel, titanium, and aluminum) and two type – IV die stone materials (Kalrock and Zhermack elite) are used to make the samples. A total of sixty implant analogs (20 each), sixty corresponding abutments (20 each) and 720 screws (240 each) were taken, which includes stainless steel, titanium, and aluminum manufactured by Adin, Genesis, and Equinox/Myriad plus, respectively. Addition silicone (light body consistency) was used to make an impression for the internal thread of implant analogues. The obtained samples are tested for external diameter and internal diameter of implant analogues, the marginal gap between analogue and abutment while reusing the implant analogues at the interval of times (0, 3rd, 6th, 9th, and 12th) using a stereomicroscope at ×50. Here the measured values at “0” interval were considered as the control group. The values obtained were statistically analyzed using the one-way ANOVA, independent t-test, and dependent t-test for multiple comparisons. Results: Based on the results obtained, there was no change in the external diameter of three materials of implant analog in both die materials. There was an increase in the internal diameter of implant analogs in which the aluminum material exhibits more increase from 0 to 12th interval, and there was an increase discrepancy in the marginal gap between implant analog and abutment in which the aluminum material has more increase from 0 to 12th interval followed by the stainless steel and titanium implant analogs in both die materials. In between the two die materials, no significant difference was observed in all three parameters. Conclusion: From the study, the following inferences are drawn: that titanium implant analogs can be used more than three times but not more than six times, stainless steel implant analogs can be used for not more than three times, and the aluminum implant analogs can be used for one time only. Hence, among the three materials, titanium implant analogs w","PeriodicalId":212982,"journal":{"name":"Journal of Dental Implants","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129614697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A vascularized interpositional periosteal-connective tissue (VIP-CT) graft comprises pedicled connective tissue which is rotated anteriorly to the recipient site. It maintains intact vascular supply thus minimizes chances of graft necrosis and the amount of graft shrinkage. The objective of this case series was to achieve stable, esthetically pleasing pontic site using VIP-CT graft in the anterior maxillary region. In the present case series, the pontic site was developed successfully in three patients having ridge deficiency using a modified approach of VIP-CT. After soft-tissue augmentation, the site was altered by placing a cantilevered provisional ovate pontic. Once the emergence profile had achieved by molding the grafted area, permanent restoration using the adjacent implant as an abutment was delivered to patient. Esthetically pleasing anterior restorations, satisfying the patient's esthetic demands were obtained, and results were found stable up to a period of 9–24 months and thus can be concluded that modified VIP-CT is a predictable approach in anterior esthetic areas to enhance the emergence profile.","PeriodicalId":212982,"journal":{"name":"Journal of Dental Implants","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132522257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Histological investigations of the bone bed in humans are limited, which in turn hampers opportunities to deepen knowledge about the remodeling process around dental implants. Purpose: The aim of this pilot study was to comparatively evaluate the bone density changes around root-form, threaded collar, two-piece endosseous implants at three different levels as influenced by early and conventional protocols using cone-beam computed tomography (CBCT). Methodology: Twenty implants were placed in 20 patients who were randomly assigned to two groups. Group A (n = 10 implants, 10 patients) received conventional loading protocol and Group B (n = 10 implants, 10 patients) followed early loading protocol following implant placement. Bone density changes were evaluated and compared as influenced by early and conventional protocols using CBCT (gray values).The gray values were measured at the apical level, middle region of radiological implant length, and at the crestal level. The measurements were made immediately (T0) and 36 weeks (T1) post implant placement. Results: Intergroup comparison of bone density changes was done between Group A (conventional loading) and Group B (early loading) from immediate post implant placement to 36 weeks post implant placement follow-up. From immediate post implant placement to follow-up, significant difference was seen in bone density of Group A and Group B at apical and middle levels as P < 0.05, but at crestal level, no significant difference was seen. Conclusion: Under the conditions of this study, early loading significantly densified more bone as compared to conventional loading. Further studies are required to determine CBCT gray values and its correlation with computed tomography Hounsfield units for quantification of the bone.","PeriodicalId":212982,"journal":{"name":"Journal of Dental Implants","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115074981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The need for placing the implant immediately post extraction helps reduce the alveolar ridge resorption and also maintain good soft-tissue contours post placing the implant and during rehabilitation. However, a cause of concern occurs when the buccal cortical plate is thin, especially in the upper anterior region. This poses a direct implication in the maintenance of primary stability and buccal contour of both hard and soft tissues, thus compromising esthetics. The socket-shield technique (SST) is a recent advancement in placing immediate implant post extraction. The maintenance of the buccal root section helps retain both the compromised buccal cortical plate and soft-tissue contour, thus providing a better esthetic profile. In view of the same, two patients were provided immediate implants with SST; one with immediate loading of implant and other with delayed loading method, and postoperative radiographic analysis was carried out to evaluate bone density around the implant.","PeriodicalId":212982,"journal":{"name":"Journal of Dental Implants","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123990622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
