PRODUCT PROFILE: Processing and Properties of Endosseous Dental Implant Surfaces: Design for Increased Osseointegration Potential

FIGURE 6 Illustration of transverse force components acting on threaded and porous-surfaced implants and the resulting peri-implant stress distribution. The 3-dimensional interlock of bone with the porous-surfaced implant results in a more uniform peri-implant stress distribution.

Successful treatment using endosseous dental implants is dependent on the formation and maintenance of secure implant-to host bone fixation. This criterion for success has been recognized since the late 1970s as a result of early reports by Branemark and co-workers on successful use of threaded, screw-shaped cpTi implants placed using a careful two-stage surgical procedure.1 … Read more

PRODUCT PROFILE: Achieving Osseointegration in Soft Bone: The Search for Improved Results; PRODUCT PROFILE

FIGURE 8 Dense bone insertion of 4.7 mmD tapered Screw-Vent into a straight osteotomy.

Modern implantology represents a continuum of developments spanning more than a century. Most early implant restorations were relatively short-lived, due to a lack of fully biocompatible materials.1 Increased predictability was finally achieved with Strock’s2 introduction of cobalt-chromium implants in 1939. The following year, Bothe et al.3 made the startling observation that living bone forms a … Read more

Pulpal and periradicular pathology develop when the dental pulp and periradicular tissues become exposed to microorganisms. In experimental germ free conditions pulpal and periradicular tissues fail to show the development of pathosis and associated lesions when exposed to bacteria.1,2 The conclusion: microorganisms are the main irritants of the dental pulp and periodontium, and sealing the … Read more

FIGURE 12 Post-operative dive view of patient after successful management of chronic diffuse sclerotic osteomyelitis of mandible.

Chronic diffuse sclerosing osteomyelitis of the jaws is believed to be an inflammatory response to microorganisms of low virulence. Although carious, non-vital teeth have been implicated in the etiology and progression of this disease, chronic periodontal disease appears to provide a more common portal of entry for bacteria. Clinical Features Although this condition may affect … Read more

IMPLANTOLOGY: How Many Implants are ‘Enough?’

FIGURE 11 Clinical photograph of Case #3 showing the bar attached to the implants. This produces much greater support, and a much better prognosis. The prosthesis can now be made as an RP4 (implant born/implant retained).

There are many Implant dentists who believe that any given case might be ‘over treated,’ while the next case is considered ‘under-treated.’ The number of implants used in each individual case can vary with: a) What does the patient wants or what can they afford? b) What the dentist is trying to accomplish? c) How … Read more
