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.

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 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.
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 ]
A protective splint is fitted to protect the implant during the healing period. Recovery time is very fast as neither soft nor hard tissue is traumatised. Typically, even the day after implant placement there is no swelling, bruising or pain. After 8–12 weeks' healing period, the final crown may be fitted by a family dentist.
Early implant designs had the potential to loosen from their attachment to the bones, typically becoming painful ten to twelve years after placement. In addition, erosion of the bone around the implant was seen on x-rays. Initially, surgeons believed this was caused by an abnormal reaction to the cement holding the implant in place.
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 ...
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.
