screw-retained implant restorations have an advantage of predictable retention as well as retrievability, and obviate the risk of excessive sub-gingival cement commonly associated with cement retained implant restorations. screw-retained restorations generally have screw access holes, which can compromise esthetics and weaken the porcelain around the holes. the purpose of this study is to descr...

abstract fixed dental prosthesis success requires appropriate impression taking of the prepared finish line. this is critical in either tooth supported fixed prosthesis (crown and bridge) or implant supported fixed prosthesis (solid abutment). if the prepared finish line is adjacent to the gingival sulcus, gingival retraction techniques should be used to decrease the marginal discrepancy among ...

objective: the aim of this study was to evaluate and compare the status of supporting tissue around implant-supported fixed partial denture with or without cantilever clinically and radiographically during a four-year period. materials and methods: one hundred and fifty nine patients who were treated by 482 implants supported fixed partial prosthesis with and without cantilever after at least f...

background: assessment of prosthetic needs in a special population would aid in planning the oral health service programs. the aim of this study was to assess the dental prosthetic status and prosthetic needs in a sample of green marble mine laborers of udaipur, india.     methods: the study population comprised of 513 green marble mine laborers who were divided into four age groups (15-24, 25-...

background and aim of study: long span is seen in many clinical situations, treatment planning options of these cases are difficult and may require: fpd, rpd or isp. each option has its own disadvantages: mechanical, patient relief and cost respectively. this article will evaluate the stress distribution of another treatment option which is adding a single supporting implant to the fpd by using...

objective: the aim of the present study was to retrospectively evaluate small-diameter (3.3 mm) straumann® dental implants placed in the maxilla or the mandible over a period of 5 years in function. materials and methods: twenty- eight partially edentulous patients received a total of 48 implants over a 5-year period. after the standard healing period (3 to 6 months), the implants were restored...

OBJECTIVES The aims of this study were to evaluate patient satisfaction with fixed prosthesis following placement and to assess the oral health and oral hygiene practices awareness by survey questionnaire. MATERIALS AND METHODS One hundred and ninety-two questionnaires were filled by patients wearing fixed prosthesis; the questionnaire included the subjective perception of treatment with fixe...

The fabrication of an implant-supported fixed complete denture prosthesis involves multiple clinical and laboratory steps. One of the main steps is to provide the patient with an interim fixed prosthesis to evaluate the patient's esthetic and functional needs as well as to enhance the patient's psychology before proceeding to the definitive prosthesis. Different techniques for fabricating inter...

INTRODUCTION Every patient needs a comprehensive treatment planning. Dentists must consider the advantages and disadvantages of the available implant prosthetic options and match them to patient's expectations. Hybrid denture prosthesis is one, i.e., fabricated and retained by screw threaded into implant abutments, most of the time on four implants. Sometimes due to failure of an implant, the p...
