Inflammatory Impact on Tissues Surrounding the Dental Implant of Singular Abutments Bonded onto Titanium Base - A Randomized Controlled Trial.

Introduction: In dental implants, the biochemical connection between titanium (ti) and bony tissue has been well established. The properties of dental implants such as osseointegration and stability depend upon composition, design of the implant, connection, and design of the abutment, and additional removal of abutments. Recently, laser-generated micro-grooved surface (LSS) and TI abutments are the main focus of preventing peri-implant inflammation. Objectives: To assess the inflammatory impact of singular abutments bonded onto titanium bases on tissues surrounding the dental implant. Methods: Twenty subjects were enrolled. Only those subjects were enrolled who were scheduled to undergo prosthetic rehabilitation of missing teeth. Random division of subjects was done. Group A: Test abutment group and Group B: Control abutment group. The test abutments comprised Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) titanium abutments bonded onto titanium abutments. However, control abutments were customized and only one-piece CAD/CAM titanium abutments were enrolled.On 6 months and 12 months of follow-up, the clinical and radiographic examination was done. Assessment of the bone level changes, clinical variables, and IL-1b levels was assessed. Results: Mean IL-1b levels in Group A subjects at baseline, 6 months, and 12 months were 1.52 pg/mL, 1.69 pg/mL, and 1.55 pg/mL, respectively. Mean IL-1b levels among the patients of group B at baseline, 6 months, and 12 months were 1.56 pg/mL, 1.71 pg/mL, and 1.54 pg/mL, respectively. Conclusion: Within the limitation of the study, it can be concluded that the impact on the inflammatory condition of surrounding tissues of dental implant does not vary significantly between single abutments bonded onto Titanium bases and singular abutments.

Survival and Complications of Single Dental Implants in the Edentulous Mandible following Immediate or Delayed Loading: A Randomized Controlled Clinical Trial.

Introduction: The lifespan of an edentulous mandible with one median implant to hold a full denture for 24 months was evaluated to see if the early loading had any impact on it. Single-implant denture retention for the mandibular region was proposed by "Cordioli et al. in the 1990s. Objectives: Whether rapid loading and placement of a "single median implant" may result in the implant survival rate comparable to rehabilitation with a single implant and second-stage surgery. Methods: It was found that 81 of the 158 implant recipients had quick loading, whereas the rest had delayed loading (77 patients). Patients in the context of "delayed loading group" had follow-up appointments at 1 month, 4 months, 12 months, and 24 months. In addition, the nine implants failed in the 3 months after loading in a quick loading group, while just one implant failed before loading. Median implant survival at 2 years was the study's main goal. Direct loading had a 7% fatality rate advantage over traditional loading because of the alleged advantages of immediate loading, including the avoidance of second-stage surgery. Prosthetic problems were evaluated using Fisher's exact test. Results: A higher rate of implant survival was not seen when implants were loaded more quickly (P = 0.81). A statistically significant difference (P = 0.019) was seen in implant survival between the therapy groups. Conclusion: Single implant loading in an edentulous mandible has a worse survival rate than delayed loading, according to all available research.

Surface Characteristics of Different Zirconia Dental Implants: A Comparative Study.

Introduction: The invention of dental implants has replaced the fixed partial dentures for the replacement of the teeth. Hence, in the present study, we compared the surface characteristics of various zirconia dental implant systems. Materials and Methods: We conducted an in vitro comparative study of 50 implants of the dental implant systems "Straumann pure ceramic implants (SC) and Bredent dent whiteSKY™ (BW)." Scanning electron microscopy (SEM) was used to compare the groups for the surface characters at the different regions of the implant surface. Results: SC showed deep markings on the surface and droplets, and BW showed smoother surface and bigger droplets under the SEM. Conclusion: SC may perform better in the clinical conditions as the surface characters are better than the BW.

Sleep Disorders among Dental Students: An Original Research.

Introduction: With the increased stress among the students, their sleep patterns have been derailed from the routine. Hence, in our study, we aimed to appraise among the dental students the occurrence of sleep disorders. Materials and Methods: We conducted a questionnaire-based survey study among 1115 dental students of 1-4 years. The survey was based on SLEEP-50 that had 50 questions that were given scores from 1 to 4 based on the response. The scores were analyzed for the statistical connotation, keeping P < 0.05 as significant. Results: We observed that 352 students suffered from sleep disorders. The sex ratio of male:female was 25:75. No significant age variation was seen. For the various disorders, insomnia (25%), nightmares (13%), and sleepwalk (8%), circadian rhythm disorders (34%), obstructive sleep apnea (26%), and narcolepsy (30%) were noted with significant variation. The habit of alcohol was seen in 17% of students. Conclusions: The sleep disorders were prevalent among the dental students due to the great amount of stress caused in the study. They should be educated about the stress management methods and importance of sleep.

Assessment of Failure Rate of Fixed Partial Dentures: A Clinical Study.

Introduction: The most common for the replacement for the teeth are the partial dentures. Hence, in our study, we analyzed the failure rates of the fixed partial dentures (FPDs). Materials and Methods: We conducted a retrospective study from the institutional record and analyzed 150 subjects. The various factors for the FPD's failure were noted and analyzed for any statistical significance. Results: We observed a significant difference between the various factors of the failure caries, periodontitis, uneasiness, and pain. Conclusion: The chief cause for the failure of the FPDs was identified to be caries, periodontitis, uneasiness, and pain.

Occlusal Vertical Dimension and Its Association with Length of Thumb: An Original Research.

Introduction: Establishing an accurate vertical dimension at occlusal (VDO) is a challenge. Hence, we aim to find the association between the VDO and the Thumb Length (TL). Materials and Methods: We piloted an observational study by evaluating the VDO and the TL among the Dravidian and Aryan ethnicities with 200 volunteers. The comparisons were made applying the "linear regression analysis" to find the correlation of both. Results: We observed that a strong and positive relation was established for the two parameters of VDO and TL for both the ethnicities. Conclusion: We can suggest from our study that the thumb length can be used as an aid for the occlusal vertical dimension estimation.

Prevalence of Stress and Coping Disorders among Dental Students: An Original Research.

Introduction: The students pursuing professional studies such as medicine and dentistry have to endure a lot of stress. Hence, we evaluated the prevalence of stress and coping disorders among dental students. Methods: We conducted a questionnaire-based online survey study among 100 dental students of 1-4 years. The survey was based on the "modified General Health Questionnaire (GHQ-12; Goldberg and Williams, 1988)." The scores were analyzed for the statistical connotation, keeping P < 0.05 as significant. Results: We observed that over half of the dental pupils felt stressed. The dental students resorted to "Destructive coping mechanisms." Less than 15% of students sought medical and psychiatric counseling. The mean GHQ was 12 ± 1.7. Conclusions: Psychological strength is a prerequisite for good health and better performance in the studies as well as for the practice. There is an urgent need to focus on the mental health of the students specifically in the medical and dental fields.
