Comparison of Implants With Different Implant Surfaces.

A Prospective Randomized Clinical Split-mouth Study on the Influence of Implant Surface Roughness on Peri-implant Bone Stability of Implants Supporting a Mandibular Overdenture.

This study looks at how the surface texture of dental implants affects the surrounding bone and the overall gum health over time. It compares two types of implant surfaces: one partially smooth and one slightly rough. The researchers also check how these implant treatments impact patients' quality of life related to oral health after 1 year and again after 8 years.

This split-mouth randomized controlled trial aimed to assess the effect of surface roughness on long-term crestal bone remodelling and peri-implant health, comparing hybrid and moderately rough implants. As a secondary aim, Oral Health Quality of Life (OHQoL) was assessed after 1 and 8 function years.

Inclusion Criteria:

• Totally edentulous for at least four months
• Sufficient residual bone volume to place two implants of 4 mm in diameter and 9-11 mm in length

Exclusion Criteria:

• <21 years old
• Smoking
• General contra-indications for oral surgery, e.g., full-dose head and neck radiation, intravenously administrated bisphosphonates and current chemotherapy.
