Immediate versus delayed loading of strategic mini dental implants for the stabilization of partial removable dental prostheses: a patient cluster randomized, parallel-group 3-year trial Mundt et al 2016 long-term survival data for mini implants are lacking and acceptable short-term survival rates (>90 %) of mini-implants are only documented for mandibular overdentures The short-term survival rates

Assessment of implant stability as a prognostic determinant Meredith 1998 Clinicians have reported success rates for implants as high as 90%. Endosseous Implants Osseointegration has been defined as “a process whereby a clinically asymptomatic rigid fixation of alloplastic materials is achieved and maintained in bone during functional loading.” Implant survival and implant success are quite

Oral Implant Surfaces: Part 1—Review Focusing on Topographic and Chemical Properties of Different Surfaces and In Vivo Responses to them Albrektsson et al 2004 Morra et al  found that machined implants display a lower concentration of titanium on the surface and a higher concentration of carbon than sandblasted, acid- etched, or plasma-sprayed surfaces. Wear is

Tremperature threshold levels for heat-induced bone injury: A vital-microscopic study in the rabbit Eriksson and Albrektsson 1983 Critical temperature is to be around 56° because alkaline phosphate denatured at this temperature level. Hard tissue changes after heating in the range of 47° to 50  c. The heating was performed about 10 weeks liter chamber insertion.  Acute

Clinical complications with implants and implant prostheses Goodacre et al 2003 All-ceramic crowns had the lowest incidence of complications (8%). Reviewing the literature from 1981 through 2001 The mean bone loss was 0.9 mm (range from 0.4 to 1.6 mm). The mean loss per year in subsequent years was 0.1 mm (range from 0 to

Criteria for success of osseointegrated endosseous implants Smith et al 1989 1. Individual unattached implant that is immobile when tested clinically   2. Radiograph that does not demonstrate evidence of peri-implant radiolucency   3. Bone loss that is less than 0.2 mm annually after the implant’s first year of service   4. Individual implant performance

Brinemark, M.D., Ph.D. 1983   Separate studies were performed on the healing and anchorage stability of titanium tooth root implants or fixtures of various sizes and designs.    We found that when such an implant was introduced into the marrow cavity, and following an adequate immobilized healing period, a shell of compact cortical bone was
