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 ...

Vaginal agenesis is one of the major congenital anomalies of the female genital tract. It may present either as an isolated developmental defect or within a complex of more extensive anomalies. Most commonly it is associated with Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome. The correction of vaginal agenesis requires the creation of a neovaginal cavity that is dissected between the bladder and the rectum. After reconstruction of space for vagina surgically, a long-term vaginal stent use is required to maintain vaginal width and depth and to prevent contraction. In this article is presented a case of nonsyndromic agenesis of vagina in a 14-year-old girl and its surgical management using custom fabricated acrylic vaginal stent.

Keloid is cutaneous lesion characterized by fibrous growth produced as a result of aberration in the healing process. Pressure therapy, in combination with other forms of therapy, is used for the management of keloids. Clips or stents are generally used for the therapy and prophylaxis. This report presents use of presurgical compression and prophylactic passive pressure therapy with acrylic appliances for auricular keloids in a patient. Spring and magnets were used in the design of custom-made appliances for compression and retention.

Keloid is dermal lesion characterized by nodular fibroblastic proliferation, which is considered an aberration of wound healing process. It is believed to be the confused scar that does not know when to stop growing. Pressure therapy using clips or splints is widely used for the treatment of keloids; however, it is often very difficult to control the amount and direction of pressure applied. Among the most common complications of this therapy is ulceration due to excessive pressure. A case of presurgical size reduction for a large ear keloid with a custom made pressure appliance is presented. This novel design of the appliance allows for better control over the amount and direction of the pressure applied on the scar tissue.
