What type of implant surface is best suited to be exposed to the oral environment?

The machined surface is often recognized as a suitable option for exposure to the oral environment due to its smooth finish and the ability to integrate well with surrounding bone. Its reduced surface roughness minimizes plaque accumulation and enhances cleaning, which can be beneficial in maintaining oral health and increasing the longevity of the implant. Additionally, machined surfaces promote better initial implant stability and can provide sufficient osseointegration with bone, making them effective for various clinical scenarios in implant dentistry.

While other surfaces like HA coated or acid-etched can promote bone growth and integration, they may also be more prone to accumulation of debris or biofilm due to their increased roughness, which can potentially complicate oral hygiene efforts. The balance between osseointegration and oral health management is crucial, emphasizing the machined surface's effectiveness for exposure to the oral environment.
