Use of short endosseous implants and an overdenture in the extremely resorbed mandible: A five-year retrospective study

Performance of Short Implants in Partial Restorations: 3-Year Follow-up of Osseotite® Implants

“…Even more discrepancy exists when complete edentulism and partial edentulism are compared. 1,5,[14][15][16][17][18][19][20][21][22] In partially edentulous cases, the data from the literature tend to show a high implant failure rate in the maxilla (13.5%) compared to the mandible (4.4%) ( Table 5). 14-19 However, the findings from this study show similar failure rates for both jaws (Table 1).…”

“…[1][2][3][4][5] From an anatomic perspective, in the mandible, the intra-alveolar canal containing the infra-alveolar nerve, the floor of the maxillary sinus, and bone resorption in general can limit the length of implants considered for placement in these locations. Furthermore, these clinical situations usually have low bone density.…”

“…2,3,5 In these reports, implant length was not a primary endpoint but was included in the secondary analyses of overall implant function. Few studies focus exclusively on the success of short implants.…”

Implants in the severely resorbed mandibles: whether or not to augment? What is the clinician’s preference?

“…However, when using only two implants, a rotational movement of the denture is still feasible because the denture is supported by both the mucosa and the implants. To increase the stability of the denture, more implants can be placed, thereby making the denture completely implant-borne [24]. …”

Complications in alveolar distraction osteogenesis of the atrophic mandible

“…Similar survival rates (88%) were reported for implants installed after an augmentation procedure with bone grafts 10,14,16 . The alternative of installing two or four short implants in patients with extremely resorbed mandibles resulted in success percentages varying from 88 to 94% after 5 years 17 .…”
