What is the most common postoperative problem after five mandibular implants?

Gingival inflammation is considered the most common postoperative problem following the placement of five mandibular implants. This condition is typically associated with soft tissue reactions that can arise due to surgical trauma, foreign body responses, improper oral hygiene, or microbial colonization. After implant surgery, the surrounding gingival tissue may become inflamed as a response to these factors, which can lead to discomfort, swelling, and potential complications if not managed properly.

It's important to note that while other issues such as implant failure, bone resorption, and neuropathy can occur, they are generally less frequent or tend to manifest under specific conditions or complications. Implant failure may be closely monitored, but effective surgical techniques and good patient selection often result in a high success rate for implants. Bone resorption can happen, especially if there is insufficient initial integration of the implants, but it often takes time to develop and isn’t immediate. Neuropathy can arise due to nerve involvement during surgery but is also not as common as gingival inflammation in the immediate postoperative period. Hence, gingival inflammation emerges as the more prevalent issue in the context of postoperative complications for multiple implants placed in the mandible.
