Purpose: To evaluate the effect of Platelet-Rich-Plasma (PRP) and different implant surface topography on implant stability and bone levels around immediately loaded dental implants.
Materials and Methods:Dental implants were placed in subjects divided into two groups and four subgroups on basis of implant treatment with PRP and implant surface topography used. A total of 30 implants were placed, 15 in each group. For PRP group, implants were placed after surface treatment with PRP. Temporization was done within two weeks and final prosthesis was given after three months. Implant stability was measured with Periotest at baseline, one month and three months. Bone height was measured on mesial & distal side on standardized IOPA x-rays.Results: A statistically significant difference was noticed in implant stability with PRP at baseline. The effect of PRP on bone height changes was not statistically significant. A synergistic effect of PRP and square thread-form was observed on improved implant stability and bone levels; however, no such effect is seen with PRP and reverse buttress thread-form.
Conclusion:Within the limitation of this study, enhancement on implant stability and bone healing was observed with PRP treated implant surfaces, and with use of implant with square thread-form.
InTROduCTIOnModern dentistry aims to restore the comfort and health of the stomatognathic system. Dental implants have emerged as a promising option for this purpose. Osseointegration forms the basis of implant success. Studies have been conducted to establish the criteria for success and failure of osseointegration and factors affecting osseointegration [1,2]. Traditionally, an unloaded healing period was considered essential for the achievement of osseointegration of dental implants [3]. Now in implant dentistry, advanced treatment protocols such as early or immediate loading are frequently used to reduce treatment time but this poses new demands on both the primary and secondary implant stability. Implant stability is defined as the capacity of the implant to withstand loading in axial, lateral, and rotational directions [4]. Primary stability is mainly dependent on the mechanical characteristics of the original bone like its local quality and quantity, the type of implant used including its geometry, diameter, length & surface characteristics, and the surgical techniques employed [5,6].Secondary implant stability represents enhancement of the stability as a result of peri-implant bone formation through gradual bone remodeling and osteoconduction, with the possibility of new bone formation at the implant-bone interface and influenced by the implant surface characteristics [7,8]. Contemporary knowledge indicates that the degree of micromotion at the bone-implant interface during initial healing is of utmost importance in achieving good secondary stability [9][10][11].Several measures have been proposed to improve and accelerate osseous healing of endosseous implants. Platelet-Rich-Plasma (PRP) has been suggested to enhance ...
Health care is very complex sector and delivery of service is the fragmented care. Quality can be a common paradigm to address the need of all groups in health care. Quality improvement is the process approach to the organization's operational challenges. The initiative to address the quality in health care has become a global phenomenon. A quality revolution for delivery of service with patient at the center and services around it is the demand of the time. This article comprehensively reviews the quality management in health care service and aims to sensitize the health care professionals towards achieving total quality.
Bisphenol A or BPA-based epoxy resins are widely used in the manufacture of commercial products, including dental resins, polycarbonate plastics, and the inner coating of food cans. BPA is a precursor to the resin monomer Bis-GMA. During the manufacturing process of Bis-GMA dental sealants, Bisphenol A (BPA) might be present as an impurity or as a degradation product of Bis-DMA through esterases present in saliva. Leaching of these monomers from resins can occur during the initial setting period and in conjunction with fluid sorption and desorption over time and this chemical leach from dental sealants may be bioactive. Researchers found an estrogenic effect with BPA, Bis-DMA, and Bis-GMA because BPA lacks structural specificity as a natural ligand to the estrogen receptor. It generated considerable concern regarding the safety of dental resin materials. This review focuses on the BPA in dental sealants and its estrogen-like effect.
