the platform switching (pls) concept was introduced in the literature in 2005. the biological benefits and clinical effectiveness of the pls technique have been established by several studies. in this article different aspects of pls concept are discussed. crestal bone loss, biologic width, and stress distribution in this concept are comprehensively reviewed. in this article the relative publis...

Patients with Down syndrome may not be cooperative during dental treatment and, in cases of complex treatment, it is necessary to use oral or inhaled sedation and/or general anesthesia, which represent safe and efficient treatment resources. There are few reports about oral rehabilitation with dental implants in patients with Down syndrome in the literature. This paper presents the case of a pa...

Introduction: The maxillary anterior region poses the highest number of aesthetic challenges in implant dentistryas any tooth loss leads to bone resorption and collapse gingival architecture leaving inadequatebone for placement. However, immediate placement provisionalization has been a viableoption replacing failing teeth as it preserves vertical existing osseous gingivalarchitecture. A proper...

PURPOSE The purpose of this study was to assess the survival rates and interproximal bone levels for Osseotite implants that were restored with fixed provisional crowns without occlusion immediately after implant placement. MATERIALS AND METHODS Ninety-three implants were placed in 38 partially edentulous patients. All implants were immediately restored with prefabricated abutments and cement...

Purpose To demonstrate an unusual case of orbital trauma due to dental surgery complication. Observations An elderly patient who underwent dental implantation to the zygomatic bone was hospitalized in the ophthalmology department with impaired abduction of her right eye, also evident on ocular examination. Head computed tomography demonstrated damage to the lateral rectus and to the inferior ...

This clinical study assessed at 5 years both implant survival and peri-implant tissue architecture of immediately provisionalized implants placed 4 to 6 months following augmentation with demineralized bovine bone allograft and collagen membrane. Of 23 implants in 19 patients, one implant failed prior to loading (95.6% survival). Implant tissue relationships were stable following implant placem...

Implant placement in the anterior maxilla remains a challenge to even the most experienced clinician. Immediate implant placement is a risky procedure in itself and only successful in limited cases. To combine these modalities is expected to have a variety of complications and possible negative outcome. Due to the pressure of patients’ lifestyles and time constricting careers, there is an incre...

i ntroduction: bisphosphonates are  widely used  for  various bone  diseases including osteoporosis and bone tumors. one of the complications associated with these pharmaceutical agents is bisphosphonate-related osteonecrosis of the jaw. this condition may be triggered by placement of dental implants. in turn,  osteonecrosis  of  the  jaw  may  cause  failure  in  osseointegration  of implants....

Dental implants with their increasing success rates and predictability of final outcome are fast becoming the treatment of choice for replacing missing teeth. Considering the success of immediate implant placement in reducing tissue loss and achieving good esthetic results, is making it a more popular treatment modality in implant dentistry. Understanding the management of gingival tissues in r...
