Digital dentistry has gained significant attention in recent years due to its potential to improve the accuracy of implant placement and prosthesis fabrication. However, the literature on its effectiveness remains controversial, and a systematic review and meta-analysis are necessary to evaluate the available evidence. A comprehensive search was conducted across multiple online databases using MeSH keywords and Boolean operators. Data extraction was performed, and a bias assessment was conducted based on modified CONSORT guidelines. The pooled odds ratios (OR) and risk ratios (RR) and corresponding 95% confidence intervals (CI) were then calculated. Five studies met the inclusion criteria. The overall analysis showed no statistically significant difference in the accuracy of implant placement and prosthesis fabrication between digital and conventional techniques (OR: 0.95, 95% CI: 0.73 to 1.23 and RR: 0.95, 95% CI: 0.73 to 1.23). Subgroup analysis based on individual studies did not demonstrate consistent results. This review suggests that digital techniques do not significantly impact the accuracy of implant placement and prosthesis fabrication compared to conventional techniques in an in vitro setting. However, the overall evidence is limited by the small number of studies and the heterogeneity observed. Future well-designed studies, including randomized controlled trials and clinical studies, are needed to provide more robust evidence on the effectiveness of digital dentistry in clinical practice.
Background: Post and core restorations are performed (generally after treating the root canals of the tooth) when the majority of the tooth structure has been rendered ineffective to support itself/the crown of the tooth. In this clinical study, we aim to compare the difference between post and core treatment of anterior and posterior teeth and their success/failure rates. Objective: Our investigation aimed to compare the clinical survival rates of custom-fabricated cast metal post-and-cores in cases of anterior and posterior teeth while controlling for the population's age and gender, type of post material, length of the post, amount of alveolar bone tissue supporting the roots, tooth location in the dental arch, and type of cement used, as well as the effect of opposing dentition and the type of definitive prosthetic treatment received. Methods: 112 individuals who had received root canal therapy (RCT) and were chosen to receive post and core therapy following their RCT were chosen for the study, and a total of 164 teeth were scheduled to undergo the therapy. All the posts used were made of cast metal, and the patients were divided into two groups: 48 individuals had the posts placed in their posterior teeth (a total of 71 teeth in this case), and the second group was made up of the remaining 64 patients, all with 93 teeth in the anterior region. The follow-up was done twice at a six-month interval after cementation was complete. Results: No significant changes were observed between the stability of the post structures in the anterior and posterior teeth that were examined, and the survival rates were found to be similar in both instances. Conclusion: The cast metal posts performed at a similar success rate for the one-year period when the teeth were under our observation, and there were no considerable changes seen statistically. But it must be mentioned that a short follow-up period was observed, so the results might probably see some variations when a longer period of time is taken into consideration.
An epidemiological survey was conducted among the geriatric population to determine the status and need for dental prosthetics and their influence on oral health-related quality of life (OHRQoL). The study population consisted of 270 patients aged 60 or older. All pertinent demographic information, clinical data on prosthesis status and need, and the Oral Health Impact Profile (OHIP)-14 questions to assess OHRQoL were collected using a pretested structured questionnaire written in the patient’s native tongue. In addition, a type 3 oral examination was performed on a sample of the geriatric population. The OHRQoL was found to be unaffected by the prosthetic status. However, there was a strong correlation between the elderly study population’s OHRQoL and the need for a prosthetic. Of each variable in OHRQoL, physical pain, discomfort when eating, and loss of taste were the most affected in this population. The prosthetic needs of the study population must be given high priority as there are many unmet needs. The concerned health departments need to seriously consider increasing facilities with an affordable system. There is a lack of appreciation for OHRQoL. However, given that a satisfactory clinical assessment of the mouth does not always indicate good oral health status, the justification for evaluating dental care with respect to oral well-being is compelling.
Background: This review aimed to comprehensively investigate the impact of Hormone Replacement Therapy (HRT) on implant osseointegration and bone loss. The study considered factors such as HRT type, osteoporosis, smoking, and diabetes mellitus, and analysed the available literature to provide insights into the association between HRT and implant outcomes. Methods: Multiple databases were utilized, and studies with diverse designs and methodologies were included that examined the relationship between HRT and implant osseointegration. The selected studies were analyzed and relevant data on implant success rates, bone loss, and other correlations was extracted. Results: The review findings indicate that HRT has a detrimental impact on implant osseointegration, as evidenced by lower implant success rates and increased bone loss in HRT-treated individuals. The odds ratio analysis further strengthens this association, with significant values of 0.59 (95% CI: 0.50-0.70) and 0.64 (95% CI: 0.54-0.76), indicating a higher likelihood of implant failure in HRT-treated patients., highlighting the need for caution when considering HRT as a treatment option in patients undergoing implant procedures. Smoking and diabetes mellitus were also found to significantly affect implant outcomes, emphasizing the importance of addressing these factors in patient management. Conclusion: The assessments demonstrate that HRT adversely affects implant osseointegration and increases bone loss. The results suggest the importance of considering the potential negative impact of HRT on implant outcomes and the need for thorough patient evaluation and management. Further research is warranted to explore the underlying mechanisms, assess the impact of specific HRT types and dosages, and evaluate preventive strategies to mitigate the detrimental effects of HRT on implant success.
The internal and marginal adaptation of endo-crown restorations fabricated using traditional and digital impression techniques is described. Artificial intelligence (AI) was used to analyze high-resolution imaging data obtained through digital scanning and micro-computed tomography. Results showed that endo-crowns produced with digital impressions exhibited superior fit compared to those made with conventional methods. AI-based analysis provided more accurate and consistent measurements than manual evaluation. Thus, we show AI's potential to enhance the precision of prosthodontic assessments.
By adjusting the etching and polishing steps, the surface roughness may be fine-tuned. Using a nanofiber-coated surface is another way to improve osteoconduction. Furthermore, we have shown that covering the titanium surface with nanofibers increases cell adherence. There are a number of methods being researched or suggested to enhance osseointegration by alteration of the implant surface. In addition to increasing and speeding up osseointegration, the use of current surfaces in dental clinical practice may also decrease peri-implant bone loss and enhance the likelihood of re-osseointegration of a damaged surface. In this work, we summarize the literature on the cellular-substrate interaction and in vivo investigations that evaluate the response to these new surfaces. Type I collagen (Koken Co. Tokyo, Japan), polylactic acid (100,000 Da, Aldrich Chemical Company, Inc., St. Louis, U.S.), and 1,1,1,3,3- hexafluoro-2-propanol (HFP, Aldrich Chemical Company, Inc., St. Louis, U.S.) were all employed in the electrospinning process. In addition to increasing and speeding up osseointegration, the use of current surfaces in dental clinical practice may also decrease peri-implant bone loss and enhance the likelihood of re-osseointegration of a damaged surface. An innovative approach to improving osseointegration with the bone regeneration concept is to use functionalized nanofibers as a surface modification for dental implants.
