RESUMEN
Background and Aim: Tissue repair surrounding implants is essential for the cosmetic maxillary anterior zone to respond favorably to implant therapy. Grafting platelets from an individual's blood was developed to overcome the esthetic requirements and speed up healing. Advanced platelet-rich fibrin (APRF) and concentrated growth factor (CGF) are used for good healing. Our aim was to evaluate the impact of APRF and CGF on healing of tissues around dental implants in the anterior region of the maxilla. Materials and Methods: A total of 60 patients who underwent dental implant placement procedures were included in this study. They were divided into two categories: category 1 consisted of patients who underwent dental implant placement procedures without APRF and CGF (n = 30) and category 2 consisted of patients who underwent dental implant placement procedures with APRF and CGF (n = 30). Assessment of alveolar bone height and bone density was conducted using CBCT at baseline and second, fourth, and sixth month postoperatively. Results: The alveolar height and alveolar bone density in APRF group and CGF group patients was greater compared to control group patients at all follow-ups. Conclusion: APRF and CGF have a positive effect on the tissues around dental implants, promoting faster and better tissue healing around dental implants.
RESUMEN
Background: Dental implants have been essential to the therapy of patients who are partially edentulous. Aim: Clinical evaluation of the long-term survival and success rates of different types of implant-supported prostheses. Materials and Methods: Patients who had a healthy edentulous ridge of three missing teeth in the posterior jaw in which two or three dental implants were placed having any of three prostheses, namely, three-unit fixed dental prostheses (FPD) on two implants, three splinted crowns on three implants, and three splinted crowns on three implants were included. Results: The survival rate in all patients with dental implants having different types of prostheses was 94.9%. The survival rate in FPD, three splinted crowns, and three nonsplinted crowns was 100, 88.5, and 93.6% respectively. Conclusion: FPD loaded on two dental implants was found to have a greater long-term survival rate and success rate with a lower frequency of peri-implantitis and prosthodontic complications.
RESUMEN
BACKGROUND: Tobacco usage can be equated to an unending progressive pandemic which continues to spread globally at an alarming unhindered pace. Dental surgeons have a key role in initiating reduction and even cessation of tobacco habits. Hence, the present study was undertaken for analyzing the habits of tobacco use among dental and nondental students of Indian population. MATERIALS AND METHODS: A total of 500 dental students and 500 nondental students were enrolled in the present study. Among dental students, only interns were enrolled across different dental colleges of India. A questionnaire was framed and was sent to all the students in the form of Google Forms. The questionnaire contained questions pertaining to the assessment of prevalence of tobacco use and type of tobacco use habit. All the results were recorded and analyzed. RESULTS: Five hundred dental students and 500 nondental students were enrolled. Among the dental group, tobacco use habits were present in 23.8% of the students, whereas in the nondental group, tobacco use habits were present in 43.6% of the students. While comparing the prevalence of tobacco use habits among the dental and nondental groups, significant results were obtained. In the dental group, smoking habit and chewing habit were present in 44.54% and 32.77% of the students, respectively. In the nondental group, smoking habit and chewing habit were present in 52.29% and 29.82% of the students, respectively. While comparing the pattern of tobacco use among students of the two study groups, nonsignificant results were obtained. CONCLUSION: There is an urgent need of tobacco cessation programs in the community to decrease the morbidity and mortality associated with it.
RESUMEN
BACKGROUND: Dental implants have an important role in mainstream dental practice today to restore esthetics. The present study was conducted to evaluate the microleakage at implant abutment and prosthesis interface in cemented implant-supported prosthesis. MATERIALS AND METHODS: The present study comprised sixty replicas of abutment analog with length 5 mm, width of platform 4.8 mm, and taper 6° which were milled and divided into three groups. In Group I, nickel-chromium copings were fabricated; marginal gap was evaluated with optical microscope and luted with zinc oxide noneugenol cement, Group II with zinc polycarboxylate cement, and Group III with zinc phosphate cement. Microleakage was scored by the method used by Tjan et al. RESULTS: The mean microleakage score in Group I was 2.5, in Group II was 1.9, and in Group III was 1.05. The difference was significant (P < 0.05). CONCLUSION: All cements showed microleakage. Minimum microleakage was seen with zinc phosphate cement than zinc oxide noneugenol cement and zinc polycarboxylate cement.
RESUMEN
Traditionally, periodontics has been instrumental in treating hard- and soft-tissue defect. Surgical and regenerative periodontal procedures can reconstruct the three-dimensional architecture of the hard- and soft-tissue defect. However, at times, these invasive procedures leave the patients with an esthetic problem. In such situations, the defects can be treated by the prosthetic approach. A predictable esthetically pleasing and functional outcome without any surgical procedure is being a choice of treatment for many. This article discusses about the treatment for the defect of excessive hard and soft tissue, using porcelain fused to a metal restoration with gingival-colored porcelain for both tooth-supported and implant-supported fixed prosthesis.
