Ten‐Year Results of a Prospective Study Using Porous‐Surfaced Dental Implants and a Mandibular Overdenture

Abstract

Short free-standing dental implants with a sintered porous surface used for implant fixation are a predictable and effective means of retaining a mandibular overdenture in patients with advanced mandibular ridge resorption.

Calcium phosphate sol–gel-derived thin films on porous-surfaced implants for enhanced osteoconductivity. Part II: Short-term in vivo studies

“…For both orthopaedic and to a lesser degree dental implants, total avoidance of loading is not possible since muscle forces invariably will act at the implantation site and, in addition, accidental unintended loading may occur. Excessive loads resulting in relative movements greater than a critical level (>50 mm or so [6]) will inhibit bone formation and ingrowth and result instead in fibrous tissue ingrowth and anchorage [7] or, in the extreme, fibrous tissue encapsulation [8] thereby preventing the desired implant osseointegration. Because of this, a period of non-functional loading for three to four months normally is recommended for patients receiving porous-coated joint replacement implants.…”

Design and validation of a short-implant rehabilitation model

“…16 The use of rough surfaces, by increasing the implant -bone contact area, has also been documented as having a positive impact on the biomechanical performance of short implants. 4,17,18 Likewise, the choice for an internal connection with the platform shifting concept seems to promote a better sealing and less micromovements, promoting the preservation of the bone crest level. [19][20][21] However, if the safety of use seems to be well established, some concerns and controversial results still exist.…”

A Retrospective Study of Sintered Porous-Surfaced Dental Implants in Restoring the Edentulous Posterior Mandible: Up to 9 Years of Functioning

“…The survival rate of 125 sintered porous-surfaced implants in the anterior mandible was 92.7% after 10 years. 31 Of the 122 implants in this study, the survival rate of the 81 short (5.0, 7.0, and 9.0 mm) sintered porous-surfaced implants in the posterior mandibles was 96.3% for up to an 8-year functional period. Three-dimensional surface porosity of an implant allows mechanical fixation by bone ingrowth into a porous surface 32 by distributing the occlusal force on the bone effectively, which decreases bone loss.…”
