Failure rate
The percentage of failures in a study or clinical trial, of a procedure or a device (e. g. implant), which do not meet the success criteria or fall into the failure criteria, defined in the study protocol.

Fibrin Assisted Soft Tissue Promotion
Fatigue
Progressive weakening of a structure by accumulating embrittlement and crack formation/propagation.
Fatigue failure
A structural failure caused by multiple loading episodes when all loads lie below the structure´s ultimate strength.
FDA
The Food and Drug Administration (FDA or USFDA) is a federal agency of the United States Department of Health and Human Services in the USA. The FDA is responsible for protecting and promoting public health through the control and supervision of food safety, tobacco products, dietary supplements, prescription and over-the-counter pharmaceutical drugs (medications), vaccines, biopharmaceuticals, …
FDA-Approval
FDA approved requests are for items that are new or substantially different and need to demonstrate “safety and efficacy”.
FDA-cleared
FDA clearance requests are for medical devices that prove they are “substantially equivalent” to the predicate devices already on the market.
FDBA
Freeze-dried bone allograft Bone harvested from donor cadavers, washed, immersed in ethanol, frozen in nitrogen, freeze-dried and ground to similar particles ranging from 250 to 750μm. It acts primarily through an osteoconductive process, as inductive proteins, often found in only minute quantities, are only released after the resorption of the mineral.
FDM
see Fused Deposition Manufacturing Fused Deposition Modeling also: FFF = Fused Filament Fabrication
FFI
free from infection
Fibroblasts
Cell found within the connective tissue that is responsible for the synthesis of collagen fibers and the ground substance of connective tissue.
Fibrous encapsulation
Layer of fibrous connective tissue between the implant and surrounding bone.
Finite element analysis
A numerical method for solving problems of engineering and mathematical physics. Software technique used to study stresses and strains on mechanical parts or components. Virtual prototyping software, often a component of CAD software programs, automatically generates the simulated mechanical loads for FEA The finite element method formulation of the problem results in a system of …
Fixation screw
Screw used for the stabilization of a block graft, bone substitue or a barrier membrane.
Fixed prosthesis
Dental A restoration that is not removable by the patient. The restoration may be partial arch (FPD: Fixed partial denture), or complete arch (FCD: Fixed complete denture.
Fixed removable
Dental Prosthesis fixed to an implant or implants, only removable by the dentists.
Fixture
Dental Root-form dental implant (synonym)
Flapless implant surgery
Dental Surgical technique where no soft tissue flaps are raised or a circular piece of tissue is removed for implant placement.
fluoroplastic
Fluoroplastics stands for a group of plastics where the molecules contain carbon and fluorine. Fluoroplastics tend to have special properties:- Very high working temperatures. Non-stick characteristics. Very high resistance to chemical and solvents. Very high electrical resistance. The more common members of the fluoroplastics family, with which we work, are:- PTFE (PolyTetraFluoroEthylene) PTFE is the …

Friction fit
State of retention of an implant at the time of insertion that results from slight compression of the osteotomy walls by the implant body. Components retained to an implant by friction.

Fused Deposition Modeling
Fused Deposition Modeling (FDM) is a 3D printing process that uses production-grade thermoplastic material to produce prototypes and production parts. Completed parts are robust, paintable and can be sealed to be impervious to fluids. During the build process, melted plastic is deposited layer by layer to create a two-dimensional cross section of the model. This …
