Introduction: Titanium is the most commonly used bio-inert implant material. Nevertheless, there is a possibility of systemic release of metal ions, which could have clinical implications like implant failure and toxicity. This prospective study focuses on the evaluation of serum metal ion levels in patients receiving dental implants. The aim of the study is to evaluate the release of titanium, aluminium, and vanadium from dental implants by comparing the preoperative and postoperative serum levels of these ions. Methodology: Serum samples were collected from 30 patients undergoing dental implant placement preoperatively and postoperatively at intervals of 6 weeks, 3, 6, and 12 months. These samples were analyzed for titanium, aluminium, and vanadium levels using Inductively Coupled Plasma Optical Emission Spectrometry. The difference in preoperative and postoperative serum levels was measured and statistically analyzed using the paired t -test. Results: There was a slight difference in the postoperative levels of titanium and aluminium (2.30 and 4.07 mg/dl) as compared to the preoperative levels (2.28 and 2.30 mg/dl), which was statistically insignificant ( P > 0.5). The serum levels of vanadium were too insignificant to be detected by the instrument (<0.0088 mg/dl). Discussion: Mild increase in the titanium and aluminium levels in blood serum was noted. These metallic ion levels might increase significantly due to which further clinical research with larger sample sizes and a long-term follow-up period is required to evaluate the clinical effects of metallic ion release from dental implants. There is no significant difference in the serum metal ion levels before and after the implant placement, although a little increase is observed in the aluminium ion levels after the implant placement.
Introduction: In recent years, implantology has increasingly advocated the concept of immediate loading, even with single implants. It is defined as the placement of a prosthetic restoration within 48-72 hours after implant placement. Among the other advantages of immediate loading like overall treatment reduction in timing, with function, cosmetic and psychological benefits for the patient. This case described a new surgical concept and a technique to fabricate screw-retained provisional crowns for immediate loading of free-standing single tooth implants. Hence the aim of this study is to evaluate immediate functional loading with single piece implants Materials and Methods: For rehabilitation with basal implants in sites after immediate extraction, a 2-mm twist drill, the first cortex (alveolar) was drilled and then drilling was continued till the basal cortex (nasal floor/sinus floor/lingual cortex/pterygoid bone), which was perceived as a dip. For rehabilitation with compressive screw implants in healed edentulous sites, the compression screw implants in the upper and lower jaw were inserted with the primary aim of achieving stability through compression of trabecular bone along the vertical (endosseous) axis of the implant. Frequency tables and chi square tests were used to analyze the data. Results: There were 30 patients with 76 implants present and assessed for this study. The mean age of the participants was 47.43±16.93. In the study participants, 30% of the participants had hypertension, 20% had diabetes mellitus and 20% had smoking habit. BCS and Compressive type of implants were both used in the study. In 51.32% sites, BCS implants were used and 48.68% sites Compressive type implants were used depending on the clinical situation. For the success of the implant, many criteria was assessed such as Implant stability quotient, mid-buccal gingival level and inter proximal gingival papilla, absence of complications (pain, discomfort, infection, bone loss and mobility). Results showed that there was a significant association found between diabetes mellitus with mobility, bone loss and discomfort. Contrastingly there was no association between smoking habit and any of the complications affecting the success of the implant. This showed that systemic disease plays a major role in the success of the implants. Conclusion: The high cumulative implant survival rate for the devices and the technology of the Strategic Implant® indicates (within the limitations of this study) that the immediate functional loading concept with cortically anchored implants or implants providing corticalization of spongious bone for the rehabilitation of partially edentulous segments and for single-tooth replacement in maxilla and mandible can be a viable concept even in cases where extractions of teeth were done simultaneously. Keywords: Single implants, immediate loading, Compressive implants, implants, BCS implants.
