Dental implants require healthy bone for successful osseointegration. However, bone health can become compromised by aging and/or the presence of underlying medical conditions. The severity and complications associated with these medical conditions usually indicate that they require medication for successful management. Some of these medications may undoubtedly exert effects on bone through direct or indirect mechanisms and, therefore, may also affect osseointegration. These include antihypertensive drugs, oral hypoglycemic agents/insulin, hormones (corticosteroid, thyroxin, and tamoxifen), and antiresorptive agents, including bisphosphonates and anti-angiogenic agents. Part three of this paper reviews the current knowledge regarding the effects of antiresorptive agents on the outcome of implant therapy.

Aim of the Study: To evaluate and compare bite pressure among individuals with implant prosthesis on one side and natural dentition on the contralateral side in the mandibular first molar region using the Nupai bite scan system. Materials and Methods: A total of 30 individuals (15 in which implant prosthesis on the right side and 15 in which implant prosthesis on the left side) with implant prosthesis on one side and natural dentition on the contralateral side participated in the study. The bite pressure was measured at the first molar area on both sides using Nupai bite scan. Results: Maximum bite pressure, average bite pressure, and the amount of the pressed area were found to be more on the natural dentition side in comparison to the side with implant prosthesis. The average pressure on natural teeth was 25.33 MPa and on implant prosthesis, 21.27 MPa. Conclusion: The present study concludes that the measured bite pressure at the natural dentition side is found to be higher than those at the fabricated implant prosthesis side. P value for average bite pressure is 0.033, which is significant (P < 0.05).

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.

Background: A dental implant is an artificial root inserted surgically in the process of single or multiple teeth replacements. 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.

The rehabilitation of full-arches with implant-supported prostheses is a widespread practice in implant dentistry. However, some cases require additional techniques to solve the same clinical case. The purpose of this case report is to present a maxilla total rehabilitation with implant-supported prosthesis in a patient with vertical maxillary excess requiring osteotomy, which was performed with piezoelectric to remove the bone platform, providing the patient with better esthetics and prosthetic space for proper hygiene and maintenance of the prosthesis.

Success rates for osseointegrated dental implants in the anterior mandible are very high. Due to these success rates, as well as lower costs, it is common to treat edentulous patients with just two implants, which will act as anchors for retention of the overdenture. The implant-retained overdenture is an alternative treatment option in edentulous patient's rehabilitation, providing significant retention, stability, function, and esthetics. This clinical report highlights the prosthetic rehabilitation of a partially edentulous mandibular arch with implant-supported overdenture using locator attachment.
