conclusions according to this study results, implant-retained overdenture prosthesis provided better qol for iranian patients. results in the group of iod, 55.6% of the patients had “good” qol vs. 46.7% of the patients in cd group. three patients (6.6%) in both groups had “poor” qol. no significant relationship was observed between demographic factors and different dimensions of qol, except the...

OBJECTIVE This paper focused on optimal stress distribution in the mandibular bone surrounding a dental implant and is devoted to the development of a modified Osteoplant® implant type in order to minimize stress concentration in the bone-implant interface. MATERIAL AND METHODS This study investigated 0.4 mm thick layers of two elastomeric stress barriers incorporated into the dental implant ...

OBJECTIVES To analyse the microbia composition of 10 healthy dental implants and 10 chronic periodontitis patients. METHODS Subgingival plaque and peri-implant biofilm were sampled at the first molar site before and after implant restoration. The analysis was conducted by 454-prosequencing of bacterial V1 to V3 regions of 16S rDNA. RESULTS Chronic periodontitis subjects showed greater bacte...

Treatment with fixed and removable partial dentures has been the traditional method of addressing the replacement of teeth competencies in dental education. However, by 2013 the Commission on Dental Accreditation (CODA) standards will mandate a competency in "replacement of teeth including fixed, removable, and dental implants." In 2005, New York University College of Dentistry implemented a co...

Since its introduction in northern Europe in the 1960s, dental implant has been used all over the world as an option to restore teeth and periodontal tissues. In the early stage, dental implant prosthesis was used restrictively to replace removable prosthesis; currently, however, it is also used for stationary prosthesis. This treatment utilizes various methods including osseointegration after ...

The use of dental implants in the maxillary anterior region to replace missing teeth is a viable treatment option (Figure 1). There are many benefits of fixed dental implant-supported prosthetics versus traditional crown and bridge or removable tooth-borne prosthetics.1 Maintenance of residual bone, ease of oral hygiene, increased longevity, and noninvolvement of adjacent teeth are a few advant...

Dental implant has been restoring the function and esthetics lost from missing tooth. However, biomechanical implant complications are the major cause of failing implants. Therefore, implant removal is one of the indispensable dental treatments. The 70-year-old male and 66-year-old female who had discomfort on posterior implants region came to Department of Periodontology. Conventional method u...

The availability of in office Cone Beam CT (CBCT) scanners, dental implant planning software, CAD CAM milling, and rapid printing technologies allow for the precise placement of dental implants and immediate prosthetic temporization. These technologies allow for flapless implant placement, or open flap bone reduction for "All on 4" techniques with improved preoperative planning and intraoperati...

Background. Rehabilitation of edentulous jaws with implant-supported prosthesis has become a common practice among oral surgeons in the last three decades. This therapy presents a very low incidence of complications. One of them is the displacement of dental implants into the maxillary sinus. Dental implants, such as any other foreign body into the maxillary sinus, should be removed in order to...
