A study used e-PTFE membranes to cover surgically constructed average size bone defects in the mandibular angles of rats. Consequently, the e-PTFE membrane acted as a barrier to soft tissue and sped up bone healing, which took place between 3–6 weeks while no healing occurred in the non-membrane control group during a 22 week period.

Following implant placement, the template is removed. After attaching the provisional prosthesis to multi-unit abutments and sealing the screw shafts with composite material, the postoperative phase commences. In order to fabricate the permanent prosthesis, it is essential to gather up-to-date data utilizing an intraoral scanner.
Bleeding on probing is considered normal whilst tissues are healing shortly after implant placement, however, if bleeding is present months or years after placement, inflammation should be suspected. [5] Other features which may be present whilst probing include pus, the presence of a pocket around the implant and/or recession of the gums.
Following placement of the implant, healing typically takes several weeks or months before the implant is fully integrated into the bone. [ 21 ] [ 22 ] [ 23 ] First evidence of integration occurs after a few weeks, while more robust connection is progressively effected over the next months or years. [ 24 ]
Failure of a dental implant is often related to the failure of the implant to osseointegrate correctly with the bone, or vice versa. [4] A dental implant is considered to be a failure if it is lost, mobile or shows peri-implant (around the implant) bone loss of greater than 1.0 mm in the first year and greater than 0.2 mm a year after.

In implant dentistry, the implant-abutment junction (IAJ) refers to the location of intimate contact between a dental implant and its restorative abutment.. The IAJ is a focus of much attention because its morphology and location tend to affect the amount of bone resorption during the initial period of crestal bone changes immediately following implant placement.
Peri-implant mucositis is defined as an inflammatory lesion of the peri-implant mucosa in the absence of continuing marginal bone loss. [1]The American Academy of Periodontology defines peri‐implant mucositis as a disease in which inflammation of the soft tissues surrounding a dental implant is present without additional bone loss after the initial bone remodeling that may occur during ...
Nobel Biocare also develops software for diagnostics and implant treatment planning, and produces customized, patient-specific, guided-surgery templates for implant placement surgeries. Since the legal training requirements for clinicians who carry out implant treatment vary from country to country, Nobel Biocare runs a training and education ...
